From the endpoint listing.

Behavior

This is the answer to "did you send me that event" without anyone having to open a dashboard.

lastError carries your server's response when an attempt failed, and nextAttemptAt is when we will try again. Retries back off over roughly 70 hours (nine retries, ±20% jitter); after that the delivery is dead and only the event feed (GET /payments/organizations/{orgId}/events) will still have it.

Payloads are not returned. Read the event from the feed by eventId, or replay the delivery from the dashboard (one at a time, or every dead delivery in a window). A replay re-fires under the same eventId, so your deduplication still holds.

Responses

200Delivery attempts, newest first

Body

idstringRequired
eventIdstringRequired
The event's id: the svix-id header we sent, the id in the delivered body, and the id of the same row in GET /events. Dedupe on this.
eventTypestringRequired
attemptsintegerRequired
deliveredAtstring<date-time> | nullOptional
Null until an attempt is accepted.
nextAttemptAtstring<date-time> | nullOptional
lastErrorstring | nullOptional
The status your server answered with on the most recent failure (HTTP 500), or the transport error. Never your response body; we do not store one.
createdAtstring<date-time>Required

Errors

401
The key was refused. Nothing ran.
- UNAUTHORIZED: missing, invalid or revoked, or a key on a route that does not accept one.
- KEY_EXPIRED: the key passed the expiry it was issued with. Issue a new one; an expired key cannot be rotated.
- KEY_IP_NOT_ALLOWED: the key is pinned to source addresses and this request came from another.
403
A valid key that may not make this call. Nothing ran.
- FORBIDDEN: the key belongs to a different organization.
- ACCOUNT_BLOCKED: API access for your organization is suspended.
- DEVELOPER_FEATURE_DISABLED: developer tools (webhook endpoints) are off for your organization. GET /policy lists developer in features when they are on.
429
Too many requests. The default ceiling is 100 requests per minute per API credential on a 60-second window. High-volume payout and reconciliation routes declare a 600/minute override, and batch submission a 30/minute ceiling. A separate 2,000/minute per-source-IP abuse ceiling always applies.

Obey Retry-After; it is in seconds and is authoritative. A 429 means the request was refused before the handler ran. Retry reads normally; retry an idempotent mutation with its same Idempotency-Key.

Error body · Error

typestringRequired
Stable machine-readable code.
detailstringRequired
What went wrong, in a sentence. Always a string, so detail.toLowerCase() is safe.
More
This is the field to read on BAD_REQUEST and PROVIDER_REJECTED, where the type alone does not name the condition.
messagestringRequired
The same text as detail, kept for integrations written before detail existed. Read detail.
resolutionstringOptional
What to do about it, when there is a specific answer. It is not on every error (it is absent on BAD_REQUEST, NOT_FOUND, PAYOUT_NOT_CANCELABLE and DESTINATION_ACCOUNT_NOT_FOUND), so treat it as optional and fall back to detail.
statusintegerRequired
HTTP status, repeated in the body.
statusCodeintegerRequired
The same value as status, kept for integrations written before status existed. Read status.
requestIdstringRequired
Quote this to support and we can find the exact request. Also sent as the x-request-id response header, which is the only place it appears on a successful response. Success bodies do not carry it. Send your own x-request-id on the request and we use it, so your trace and ours share one identifier; otherwise we mint one.
errorsarray of stringOptional
Present on VALIDATION_ERROR; names each field that failed.
originalIdempotencyKeystringOptional
On DUPLICATE_REQUEST_DETECTED only. Send the request again with this to receive the original payout instead of making a second one. Without it there is no way to recover except by risking a double payment.
originalPayoutIdstringOptional
On DUPLICATE_REQUEST_DETECTED only. The payout the first request created.
originalBatchIdstringOptional
On a batch DUPLICATE_REQUEST_DETECTED. The run the first request created.
originalRequestIdstringOptional
On a 409 PAYOUT_OUTCOME_UNKNOWN replay. The requestId of the call whose outcome is unknown; quote it to support.
existingRecipientIdstringOptional
On BANK_ACCOUNT_ALREADY_LINKED. The recipient in your organization that already holds this account.
existingMethodIdstringOptional
On BANK_ACCOUNT_ALREADY_LINKED. The payment method on that recipient.

Branch on type, never on the status or the message. Every error type is listed with what to do about it.
