{"openapi":"3.1.0","info":{"title":"Box API","description":"Box is MailLogic's API-first mailbox service.\n\n**Authentication.** Every request carries `Authorization: Bearer <credential>`:\na Box API key (`boxk_...`), an OAuth access token, or the access token of a\nMailLogic sign-in. A MailLogic account needs no separate Box signup: its\nfirst request sets up its Box customer. API keys belong to one customer, hold\nexplicit scopes (listed per operation as `x-required-scopes`), and may be\nrestricted to one mailbox. A sign-in holds every scope. API keys are created,\nlisted and revoked with a sign-in (`/v1/api-keys`); an API key cannot manage\nAPI keys.\n\n**OAuth.** An application acting for a signed-in owner uses OAuth 2.1\n(the authorization code flow, with a proof key) instead of a key. Box is one OAuth protected\nresource, this API and its MCP server alike: the `401` names Box's\nprotected-resource metadata (RFC 9728), which names the authorization server, MailLogic's identity provider. Register\na client there (server-side applications as confidential clients, native and\ncommand-line applications as public ones), send the owner through the\nauthorization request, and the owner allows the client on Box's consent\npage, choosing its capabilities (`mailboxes:read`, `messages:read`,\n`messages:write`; only if the owner chooses them `messages:send`,\n`messages:delete`, `messages:destroy`, `junk:read`, `junk:write`, `junk:release`, `drafts:read` and\n`drafts:write`; and only if the owner chooses them `domains:read`,\n`domains:write`, `mailboxes:write`, `mailboxes:delete`, `domains:delete`\nand `usage:read`) and, optionally, one mailbox (not with those six, which\ncover the whole account). The\nresulting access token is the same on this API and on the MCP server, and so\nis the owner's authorization of the client (`/v1/authorizations`), which the\nowner can revoke at any time: the client's next request is then refused.\nAn OAuth client acts with its authorization's access only. It never has an\nowner's other capabilities: it cannot manage API keys or authorizations, and\nit cannot use the operations that need a scope outside those\n(`403 auth.insufficient_scope`).\n\n**Scopes are standing authorization.** The scopes an API key was issued, or\nan OAuth client was granted, are the owner's delegation to it, valid for\nevery call until revoked: they are not evidence that a person approved any\none call. No operation takes a confirmation parameter, and nothing in a\nrequest raises what its credential holds. An application acting for a\nperson should ask that person before each call that deletes, releases or\ncannot be undone. The operations that cannot be undone, or that lift a\nprotection, have scopes of their own that no other scope includes:\npermanently deleting mail (`messages:destroy`) and releasing mail from Junk\n(`junk:release`). A credential issued or granted before those scopes existed\ndoes not hold them. Nor does one hold the drafts' scopes (`drafts:read`,\n`drafts:write`) unless they were chosen for it.\n\n**Domains.** Every mailbox's address is on one of the customer's own\ndomains, such as `example.com`. A domain is added (`createDomain`), its\nownership is proved with a TXT record (`verifyDomainOwnership`), its mail\nrecords are added to its DNS and checked (`checkDomainDns`), and then it is\n`active`: mailboxes are created on it (`createMailbox`), and they send and\nreceive mail. A domain's `status` always says what is left to do, and its\n`mail_readiness` whether its mailboxes receive and send now. Domains\ncover the whole account: their operations need `domains:read` or\n`domains:write`, which an API key or an OAuth client can hold too, and a\ncredential without a mailbox restriction (`403 auth.mailbox_restricted`).\nSo does creating a mailbox (`mailboxes:write`). Every mailbox shows the\ndomain it is on (`domain_id`).\n\n**Deleting.** A mailbox is deleted with all its mail, permanently\n(`deleteMailbox`, `mailboxes:delete`); a domain only once it has no\nmailboxes, and deleting a domain never deletes a mailbox (`deleteDomain`,\n`domains:delete`). Each names one resource by its id; there is no bulk\ndeletion and no confirmation parameter: an application deleting for a\nperson should ask that person first. Both scopes cover the whole account,\nand an OAuth client holds them only if the owner chose them. A deletion\nthat cannot finish now leaves the resource `deleting` (`503`); send it\nagain to finish it. Once deleted, a resource is not found (`404`), like one\nthat never existed: a repeated deletion that answers `404` means the\nresource is already gone. A deleted resource's id is never used again; its\naddress or name can be used again.\n\n**Deleting mail.** Deleting a message (`deleteMessage`) moves it to its\nmailbox's trash: it keeps its id, can still be read there (`folder:\ntrash`), and still counts toward the account's stored mail. Only a message\nin the trash can be permanently deleted (`permanentlyDeleteMessage`), and\nemptying the trash (`emptyTrash`) permanently deletes everything in it;\nthat frees its storage, and cannot be undone. A message in the trash is\nmoved back out of it with `restoreMessage`: received mail to the Inbox,\nsent mail to Sent, and a message held in Junk back to Junk (restoring\nnever releases it from Junk). Mail in the trash may be deleted\nautomatically about 30 days after it was deleted, and then cannot be\nrestored. Deleting and restoring need `messages:delete`; permanently\ndeleting and emptying the trash need `messages:destroy`, which\n`messages:delete` does not include. Neither is included in `messages:write`,\nand an OAuth client holds each only if the owner chose it; a credential\nrestricted to one mailbox can use them in that mailbox. Without `junk:read`,\nemptying the trash leaves mail held in Junk, and mail not yet checked for\nit, in the trash, and counts it nowhere.\n\n**Replying and forwarding.** A message is replied to (`replyToMessage`),\nreplied to with everyone it was sent to (`replyAllToMessage`) or forwarded\n(`forwardMessage`) from its own mailbox, with the mailbox's address. You\ngive the reply's text and attachments (and a forward's recipients); Box\nworks out who a reply goes to, its subject and its place in the message's\nconversation from the message itself. Each is sent like any message: the\nsame `Idempotency-Key`, limits and errors as `sendMessage`. They need\n`messages:read` as well as `messages:send`, since what they send comes\nfrom mail you read.\n\n**Attachments.** A message's read lists each attachment with its id\n(`att_...`), file name, media type and size; `getAttachment` downloads its\ncontent, exactly as it was sent, under `messages:read`. The file name and\nmedia type are the sender's: treat them, and the content, as untrusted.\n\n**Usage and plans.** The account's plan, its limits and what the account\nuses of them are read with `getUsage`, cheaply, as a light read.\nWhether the account fits another plan is checked with `getPlanEligibility`,\nwhich measures stored mail first and is rate limited. Both need `usage:read`\nand a credential without a mailbox restriction. Neither changes the plan,\nand no operation of this API changes it directly, except the owner's own\ncancellation of the paid plan (`cancelBilling`). There are two plans: Free\nand Plus, the paid plan. Their codes in this API (`plan`, `target_plan`)\nare `free` and `starter`: `starter` is the Plus plan.\n\n**Paying for Plus.** The Plus plan is paid for monthly through Stripe,\nand a person approves that payment: the account's owner, signed in,\nprepares a Stripe Checkout page (`createBillingCheckout`) and gives it to\nthe person who pays, who reviews and approves the recurring payment there.\nBox has no payment form and never sees card details. Preparing the page\ncharges nothing and changes nothing; the account moves to Plus only once\nStripe confirms the payment, and `getBilling` then shows it. No API key or\nOAuth client can read or prepare payment. While the plan's payment is not\nin good standing, creating a mailbox, adding a domain and sending answer\n`402 billing.payment_required`; nothing is deleted, mail keeps arriving,\nand everything can still be read and deleted.\n\n**Cancelling Plus.** Only the account's owner, signed in, cancels the\npaid plan (`cancelBilling`); no API key, OAuth client or agent can. The\nowner can cancel whatever the account uses. The plan is then not renewed:\nit ends with the period already paid for, and the account keeps Plus in\nfull until then. At that end it moves to Free (3 mailboxes, 3 domains,\n3 GB of stored mail; the month's email count does not matter) if it fits.\nIf it does not, nothing is deleted: it keeps everything, held back (no new\nmailboxes, domains or sending, and mail is refused temporarily while it\nstores more than Free allows) until the owner removes what is over and\ncancels again, or pays for Plus again. Nothing is refunded.\n\n**Resuming Plus.** Until the paid period ends, the owner, signed in, can\ntake the cancellation back (`resumeBilling`): Plus renews automatically\nagain at the end of the period, and its monthly payment is charged then,\nas before; nothing is charged when it is resumed, and no new payment page\nis needed. Once the plan has ended, it cannot be resumed: the owner pays\nfor Plus again (`createBillingCheckout`).\n`getBilling` shows where the cancellation is.\n\n**Isolation.** A mailbox that does not belong to the caller's customer, or that\na restricted key may not reach, is reported exactly like one that does not exist.\nSo is a message outside the mailbox named in the path.\n\n**Errors.** Every error has the body `{\"detail\": {\"code\", \"message\", \"params\",\n\"request_id\"}}`. `code` is stable and machine-readable.\n\n**Rate limits.** Each operation counts toward one of the account's request\nallowances, by kind: light reads (mailboxes, domains, usage, events,\nwebhooks), reading mail, searching, downloading attachments, changing\nmessages, emptying the trash, checking domains, and creating or deleting\nmailboxes, domains and webhooks. Each allows a number of requests at once\nand refills at a steady rate (see each operation's `429`). An allowance is\nthe account's, shared by this API and Box's MCP server and by every\ncredential of the account. Past it, a request is refused with\n`429 auth.rate_limited`, `params.limit` naming the allowance and\n`params.scope` `account`, and `Retry-After`: the whole seconds until it\nfits again. Nothing was done; wait at least that long before retrying, and\ndo not poll in a tight loop. A request refused before it reaches its\noperation (`401`, `403`, an invalid request) counts toward nothing; one\nthat reaches it counts, whatever its outcome. Sending has allowances of its\nown instead: each mailbox's sent messages (`send.messages`, `params.scope`\n`mailbox`) and the account's recipients (`send.recipients`), charged only\nfor a new message (never for a retry of one already sent or being sent),\nbesides the plan's monthly email count. So do the attachment bytes the\naccount downloads from storage (`attachment.bytes`): downloading an\nattachment, and forwarding a message with its attachments. The account\nowner's operations keep their own limits. Separately, an operation that works on stored mail is\nrefused with `429 auth.rate_limited` and empty `params` (`Retry-After: 1`)\nwhile too many of the account's requests are already in progress.\n\n**Writes.** Sending a message needs an `Idempotency-Key`, so that retrying it\nis always safe, and so do replying to one and forwarding one. Creating and deleting a webhook take none: a retried creation\ncan create a second webhook (list them, and delete the one you do not need).\nMarking a message read or unread takes none either: repeating it changes\nnothing more. Nor does creating an API key: a retried creation can create a\nsecond key (list them, and revoke the one you do not need). Adding a domain\ntakes none: a retry answers `409 domains.already_exists` with the domain's\nid. Verifying a domain and checking its DNS can be repeated at any time.\nCreating a mailbox takes none: a local part on a domain is one mailbox, so\nretrying the same request finishes it, never a second one, and once it\nexists answers `409 mailboxes.address_taken` with its id. Deleting a mailbox\nor a domain takes none: repeating a deletion that has not finished finishes\nit, and repeating one that has answers `404`. Deleting a message, permanently\ndeleting one and emptying the trash take none either: deleting a message\nagain leaves it in the trash, permanently deleting one again answers `404`,\nand emptying the trash again deletes only what is in it then.\n\n**Junk.** Mail judged to be spam, or whose sender failed DMARC, is held in\nthe mailbox's Junk. Junk is never listed, searched or announced with the\nmailbox's other mail, and a message in Junk does not exist (`404`) for a\ncredential without `junk:read`, which an owner gives only by choosing it.\nWith it, `listJunkMessages` lists Junk and `markNotSpam` (also\n`junk:release`, which `junk:write` does not include) moves a legitimate\nmessage to the Inbox, where it is ordinary mail from then on; `markSpam`\n(also `junk:write` and `messages:delete`) moves a message from the Inbox to\nJunk. Mail for which there is no evidence\nthat the mail service's inbound checks ran is held the same way (reason\n`unverified`), wherever it is stored. Mail in Junk or the trash is deleted\nautomatically about 30 days after it went into either (`junk.expires_at`,\n`junk.retention`); held mail stored anywhere else is kept until it is\ndeleted or released. Authenticated mail, and mail in the Inbox,\nis not thereby safe to act on: message content is always the sender's.\n","version":"1.0.0"},"paths":{"/v1/mailboxes":{"get":{"tags":["mailboxes"],"summary":"List mailboxes","description":"The customer's mailboxes, or for a restricted key the ones it may reach.","operationId":"listMailboxes","responses":{"200":{"description":"Successful Response","content":{"application/json":{"schema":{"$ref":"#/components/schemas/MailboxList"}}}},"401":{"description":"No usable credential: `auth.missing_token` or `auth.invalid_token`.","headers":{"WWW-Authenticate":{"description":"Bearer authentication challenge.","schema":{"type":"string"}}},"content":{"application/json":{"schema":{"$ref":"#/components/schemas/Error"}}}},"403":{"description":"The credential lacks the operation's scope: `auth.insufficient_scope`.","content":{"application/json":{"schema":{"$ref":"#/components/schemas/Error"}}}},"422":{"description":"Invalid parameters: `request.invalid`.","content":{"application/json":{"schema":{"$ref":"#/components/schemas/Error"}}}},"500":{"description":"Unexpected error: `server.error`.","content":{"application/json":{"schema":{"$ref":"#/components/schemas/Error"}}}},"503":{"description":"Temporarily unavailable, retry later: `storage.unavailable`.","content":{"application/json":{"schema":{"$ref":"#/components/schemas/Error"}}}},"429":{"description":"`auth.rate_limited` with `params.limit` `read.light` and `params.scope` `account`: the account's `read.light` allowance (300 requests per minute, up to 120 at once), shared by this API and the MCP server and by all the account's credentials, is used up for now.

The mailbox's copy of what was sent, when it keeps one, is\nread under the same `id` (`GET /v1/mailboxes/{mailbox_id}/messages/{id}`);\ndo not rely on that copy being there, or its content being readable, as soon\nas `202` returns. `202` does not mean delivered: delivery to each recipient\nhappens afterwards, and can still be delayed or fail.\n\n**Bcc.** Each address in `bcc` gets the message as a blind copy: no\nrecipient sees it, and the message delivered to anyone has no Bcc field.\nOnly the mailbox's own copy shows them (`bcc` on `getMessage`). A Bcc\nrecipient is a recipient like any other: it counts toward the limits and\nallowances below, and its delivery is reported (and refused) like the\nothers'.\n\n**Delivery.** What becomes of each recipient is reported on the event feed\n(`GET /v1/events`), with the message's `id` as `message_id` and the\nrecipient's address (lower-cased) as `data.recipient`:\n\n- `message.deferred`: delivery failed temporarily and is being retried;\n- `message.delivered`: the recipient's mail system accepted the message.\n  It does not say that anyone read it, or where the recipient's system\n  filed it;\n- `message.delivery_failed`: delivery failed and is not retried;\n- `message.delivery_canceled`: the mail service stopped the message before\n  it reached the recipient, because sending was suspended for abuse after\n  the message was accepted; it will not be sent. It still counts toward\n  the monthly email limit.\n\nA recipient gets each of these at most once, in this order: `deferred`\n(if at all), then one of the other three, which is final (should the mail\nsystem still report a delivery or a failure for a canceled recipient,\nthat report is what stands). A recipient with\nnone of them has no known outcome yet. Some receiving systems never report\nback, so a recipient can stay that way. Deferral and failure events carry\n`data.status`, the mail status code (such as `5.1.1`) when there is one,\nand `data.reason`, its category: `recipient_address` (no such address),\n`recipient_mailbox` (for example full or disabled), `mail_system`,\n`network`, `protocol`, `content`, `policy`, `refused_temporarily` or\n`other`. Outcomes keep being reported when the mailbox is suspended after\nsending.\n\n**Recipients refused when the message is submitted.** The mail system can\nrefuse a recipient at once, when Box submits the message. Such a recipient\nis never tried, so Box reports it straight away: in the `202` response's\n`refused` list (present only then), as `failed` among the message's\n`recipients`, and with a `message.delivery_failed` event. A refusal for\nnow (a `4.x.x` status) has the reason `refused_temporarily`: the address is\nnot known to be bad, and it does not count toward the monthly email limit.\nNothing retries it: to try those recipients again, send to them later with\na new key (retrying with the same key returns the same `202` and sends\nnothing). The recipients not in `refused` were accepted for delivery, which\ndoes not mean they were delivered. If the mail system refuses every\nrecipient for now, nothing is sent at all: see `messages.send_unavailable`\nbelow.\n\n**Idempotency.** Every request carries an `Idempotency-Key` of your choice,\nsuch as a random value, unique per message you mean to send; keys belong to\nyour customer. Retrying with the same key and the same request never sends the\nmessage twice and never counts it twice:\n\n- once it is sent, a retry returns the same `202` response, with the same `id`;\n- while the first request is still sending it, a retry gets\n  `409 idempotency.in_progress`: retry after `Retry-After` seconds;\n- a different request under a key already used gets\n  `422 idempotency.key_reused` and sends nothing.\n\nA request refused before anything is sent (`401`, `403`, `404`, `413`,\n`429`, or a `422` other than `idempotency.key_reused` and\n`messages.send_rejected`) does not use up its key.\n\n**A suspended mailbox** (`status: suspended`) sends nothing: every request,\na retry of an earlier one included, is refused with `403 mailboxes.suspended`\nand leaves its key as it was. Once the mailbox is active again, the same key\nanswers as it would have before.\n\n**Sending suspended.** While the mail service has suspended sending for the\naccount, for the mailbox's domain, for the mailbox itself or for the\ncredential making the request, every send from it, a retry of an earlier\none included, is refused with `403 messages.sending_suspended`\n(`params.scope`: `account`, `domain`, `mailbox` or `credential`), and\nleaves its key as it was: nothing is sent or counted. Messages already\naccepted may also be stopped before delivery (their recipients become\n`canceled`).\nRetrying does not help; it lasts until the mail service lifts it. Incoming\nmail keeps arriving and everything stays readable. It is separate from\nthe mailbox's own suspension, from its domain's DNS and from the account's\npayment: fixing one of those does not lift it, nor does lifting it change\nthem.\n\n**A mailbox whose domain is not active** sends nothing in the same way:\nevery request is refused with `403 mailboxes.domain_inactive` and leaves its\nkey as it was. A domain is active once its ownership is verified, it is set\nup for mail and a DNS check has found its records as required; it sends\nagain only once a check finds its sending records as required after its\nownership was verified again (`mail_readiness.outbound` not `unverified`).\nMeanwhile its mailboxes and their messages stay readable, and incoming mail\nis deferred only while its ownership is not verified or it is not set up\n(`mail_readiness.inbound`).\n\n**A domain whose sending records are wrong.** When checks over at least 30\nminutes, each confirmed by a second, independent DNS lookup, find the domain's\nsending records (SPF, and the DKIM record Box signs with) wrong\n(`mail_readiness.outbound` `invalid`, `mail_readiness.sending`\n`suspended`), every send from its mailboxes is refused with `403\ndomains.outbound_dns_invalid` and leaves its key as it was: nothing is sent\nor counted. Fix the records: Box checks the domain again every 5 minutes,\nand a check (`checkDomainDns` too) that finds them as required, confirmed\nby the second lookup, lets its mailboxes send again. A DNS that does not\nanswer never suspends a domain and never lifts a suspension. If Box has not\nbeen able to confirm the sending records for 7 days because the DNS did not\nanswer (`mail_readiness.sending` `unconfirmed`), sends are refused for now\nwith `503 domains.outbound_dns_unconfirmed` and `Retry-After`, until a check\nfinds them as required. Either way incoming mail keeps arriving, everything\nstays readable, and messages already accepted are still delivered. It is\nseparate from a suspension by the mail service, from the mailbox's own\nsuspension and from the account's payment: fixing the DNS does not lift\nthose, nor does lifting them change it.\n\n**When a send fails**, the error says whether the message was sent:\n\n| Error | Sent? | What to do |\n|---|---|---|\n| `422 messages.send_rejected` | No | The message was refused. Change it before trying again. |\n| `503 messages.send_unavailable` | No | Retry later, with the same key or a new one. |\n| `503 messages.send_unconfirmed` | Unknown | Retry later with the same key. Box finds out whether it was sent, and never sends it a second time under that key. |\n| `503 storage.unavailable`, `500 server.error` | Unknown | Retry with the same key. |\n\n`messages.send_unavailable` with `params.recipients` means the mail system\nrefused every recipient for now (`params.status`: the most common mail\nstatus code, such as `4.4.5`). Nothing was sent or counted, and the key is\nunused: send it again later with the same key. Its `Retry-After` is only a\nsuggestion; no one knows when the mail system will accept it.\n\n`messages.send_unconfirmed` gives the message's `id` in `params.message_id`:\nthe id it has if it was sent. If retries keep answering\n`messages.send_unconfirmed`, Box cannot confirm that it was sent, and it\nmost likely was not. Sending it again needs a new key, and may deliver it\ntwice.\n\n**Attachments.** Each attachment is sent with its `filename` and\n`content_type`, and its bytes exactly as `content_base64` gives them. A text\nattachment (a `text/` `content_type`) may also name its `charset`: the\ncharacter set its bytes are in, sent as the attachment's `charset`. Box\nnever converts the content and never guesses a character set: without\n`charset`, none is stated and recipients read the text as US-ASCII, so name\nthe character set of any other text (for a file downloaded with\n`getAttachment`, the `charset` of its `Content-Type`). A `charset` that is\nnot plainly a character set's name, or one on an attachment of another\ntype, is `422 request.invalid`.\n\n**Limits.** Each recipient in `to`, `cc` and `bcc` counts once toward the plan's\nmonthly email limit (`403 entitlements.email_limit`), except one the mail\nsystem refused for now when the message was submitted\n(`refused_temporarily`), and a message not sent at all. Nothing can be sent\nwhile the customer's stored mail is at its plan's storage limit\n(`403 entitlements.storage_limit`). A Box address that is not accepting mail\nis refused with `422 messages.recipient_unavailable`, listed in\n`params.recipients`. At most 50 addresses each in `to`, `cc` and\n`bcc`, 100 in all, each address once across them,\n10 attachments of at most 10 MiB in total, and\n24 MiB per request (`413 request.too_large`).\n\n**Rate.** Each mailbox may send so many messages at once and then so many\nan hour (`send.messages`), and the account may send to so many recipients\n(each in `to`, `cc` and `bcc`) at once and then so many an hour\n(`send.recipients`): see `429`. Past either, the message is refused with\n`429 auth.rate_limited` before anything is sent or counted, and its key is\nunused: send it again after `Retry-After` seconds (the longer wait when both\nare used up), not in a loop. The mail service may also limit the\nrecipients sent to from each domain in an hour (`send.domain.recipients`)\nand in a day (`send.domain.recipients.daily`, `params.scope` `domain`) and\nthe account's recipients in a day (`send.recipients.daily`), refused the\nsame way. A retry of a message already sent, or still\nbeing sent, is answered as above whatever is left of these allowances, and\nuses none of them.

Events already on the feed are not delivered: read\nthem from `GET /v1/events`. `event_cursor` marks the boundary exactly:\n`GET /v1/events?after=<event_cursor>` lists the events the webhook has still\nto deliver.\n\n**The request.** The body is the event, exactly as `GET /v1/events` returns\nit (`id`, `type`, `mailbox_id`, `message_id`, `created_at`, `data`), as JSON.\nEvery event type is delivered, including types added later; skip the ones\nyou do not handle. Headers:\n\n- `Box-Webhook-Id`: the webhook's id;\n- `Box-Event-Id`: the event's `id`;\n- `Box-Timestamp`: when this attempt was signed, in seconds since 1970-01-01 UTC;\n- `Box-Signature`: `v1=` followed by the signature, 64 lower-case hex digits.\n\n**Verifying it.** The signature is the HMAC-SHA256 of the timestamp, a dot\n(`.`), and the raw request body, keyed with the webhook's `secret` (its UTF-8\nbytes), in hex. To check a request:\n\n1. read the raw body, before parsing it;\n2. check that `Box-Timestamp` is recent (within 5 minutes, say);\n3. compute `HMAC-SHA256(secret, Box-Timestamp + \".\" + raw body)` in hex;\n4. compare it with the value after `v1=` in constant time;\n5. skip the event if you have already handled its `id`.\n\n**Delivery.** Answer with any `2xx` status to accept an event. Anything else\n(another status, a redirect, a connection or TLS failure, no answer within\n15 seconds) fails the attempt, and Box sends the same event again later: after\n10 seconds, then twice as long after each further failure, at most an hour\napart. Redirects are not followed, and what the response contains is ignored.\nEvents are delivered one at a time, in the feed's order: the next one is sent\nonly once the previous one is accepted, so later events wait behind one that\nkeeps failing. An event can be delivered more than once (after a failed\nattempt that your server did in fact receive, for example): use its `id` to\ndiscard duplicates. If attempts keep failing for 3 days, Box stops and the\nwebhook's `state` becomes `failed`; nothing is lost from the feed.\n\n**The URL.** It must be `https`, on port 443 or 1024-65535, without user name\nor password or fragment, and its host must be a public DNS name or address:\nnot a private, loopback, link-local, multicast or other special-purpose\naddress, nor a name that resolves to one. Box checks this when the webhook is\ncreated and again, on the address it connects to, for every delivery. A URL\nthat is refused fails with `422 webhooks.invalid_destination`, with\n`params.reason` one of `https_required`, `credentials_not_allowed`, `port_not_allowed`, `invalid_host`, `address_not_allowed`, `invalid_url`.\n\nThe response's `secret` is shown only once.
