Get Session Webhook Delivery API Prompt Copy prompt to clipboard \

\`Retrieve one webhook delivery of a Didit verification session through the API.

Endpoint:
GET https://verification.didit.me/v3/session/{session_id}/webhook/{webhook_uuid}
(no trailing slash)

Authentication:
Send my Didit API key in the x-api-key header. A scoped key needs sessions: read and decisions: read.

Goal:
\- Read exactly what Didit sent to my webhook endpoint for one delivery and what my endpoint answered, to debug a rejected or missing event.

Behavior:
\- {webhook_uuid} is the uuid of an entry from GET /v3/session/{session_id}/webhooks/. It must belong to the session in the path; a delivery of another session returns 404.
\- request_header and request_body are JSON-encoded strings. Parse them with a JSON parser.
\- To check my signature code, recompute X-Signature-V2 from the parsed request_body with my destination's secret (the application-level secret for a delivery sent to the legacy webhook_url) and compare it with the header. A scoped key without media: read or sessions: write receives a redacted body, which no longer matches the signatures.

Example call:
curl -X GET "https://verification.didit.me/v3/session/11111111-2222-3333-4444-555555555555/webhook/9f8e7d6c-5b4a-4321-8fed-cba987654321" \
-H "x-api-key: YOUR_API_KEY"

What to read from the response:
\- response_status: the HTTP status my endpoint returned (null while queued, 504 timeout, 503 connection failure, 400 URL refused as unsafe).
\- request_url: where it was sent.
\- request_header: the X-Signature, X-Signature-V2, X-Signature-Simple and X-Timestamp values sent.
\- request_body: the webhook payload (event_id, webhook_type, session_id, status, decision when present).
\- status, webhook_type, created_at.

Failure modes:
\- 401: the API key has expired.
\- 403: missing or invalid key, a key of another application, a scoped key without the permissions above, or a request from outside the key's IP allowlist.
\- 404: the session does not exist, was deleted, or is outside a scoped key's limits, or the delivery does not belong to this session ({ "detail": "No WebhookLog matches the given query." }).
\- 429: more than 600 reads per minute for this API key; honor Retry-After.

Side effects: none. This is a pure read.

Paste into The payload inside `request_body` is the one described in [Webhooks](/integration/webhooks.md#payload-shape), and the headers are the ones covered in [signature verification](/integration/webhooks.md#signature-verification). To send the delivery again, use [Resend session webhook delivery](/management-api/sessions/resend-webhook.md). ## OpenAPI ````yaml GET /v3/session/{sessionId}/webhook/{webhook_uuid} openapi: 3.0.0 info: version: 3.0.0 title: Didit Verification API description: Identity verification API.

The primary key has full access. A named key can be scoped: none, read or write per resource, limited to some workflows or to approved sessions, to a list of IP addresses, and to an expiry date. 401 means the key is missing, wrong, revoked or expired; 403 means the key has no access to this resource or action, or the request came from an address outside its IP list; 404 on a session route means the session is outside the key's workflows or statuses.
