# envelope.sent delivered to your endpoint

`POST envelope.sent` (webhook)

InkSeal sends this request to every active subscription whose `events` array contains `envelope.sent`, or whose `events` is `null`. Verify `X-InkSeal-Signature` against the raw body before doing anything else, and deduplicate on `id`.

## Headers

- `X-InkSeal-Event-Id` string, required
- `X-InkSeal-Signature` string, required
- `X-InkSeal-Timestamp` string, required

## Payload

- object
  - `id` string, required: Stable event id, derived from the transition rather than the clock. Every retry of this event carries the same value.
  - `type` 'envelope.sent', required: The event type.
  - `data` WebhookEnvelopeSentPayload, required: An envelope's invitations went out and signing is under way.
    - `envelopeId` string, required: Public id of the envelope.
    - `documentId` string, required: Public id of the document.
    - `documentName` string, required: The document's original filename.
    - `subject` string, nullable, required: The email subject configured on the envelope, or null.
    - `signingOrder` 'parallel' | 'sequential', required: Whether signers were invited all at once or in order.
    - `sentAt` string, date-time, required: When the send committed.
    - `signers` object[], required: Every signer on the envelope.
      - `id` string, required: The signer's public id.
      - `name` string, required: The signer's display name.
      - `email` string, required: The signer's email address.
      - `status` string, required: The signer's current status.
      - `signedAt` string, date-time, nullable, required: When this signer signed, or null.
  - `timestamp` string, date-time, required: When the transition committed. Not the same as X-InkSeal-Timestamp, which is when this attempt was made.

## Acknowledgement `200`

Acknowledged. Return any 2xx, with or without a body, as soon as the event is stored; do your work afterwards. Anything that is not a 2xx, including a redirect (redirects are never followed) and a response slower than the 30 second timeout, counts as a failure and is retried with exponential backoff from 60 seconds, doubling per attempt and capped at 1 hour, for at most 6 attempts. After the sixth the event is terminal and only a manual retry through POST /webhooks/{webhookId}/events/{eventId}/retry will send it again.
