- Know when a job finishes, without polling: Captain sends a signed HTTPS request to your endpoint when an indexing job ends. Each job sends exactly one event:
job.completed, job.completed_with_errors, job.failed, job.timed_out or job.cancelled, with the job_id, file counts and a link to the full job. See Webhooks.
- One endpoint for every job: an endpoint receives events for every indexing job in the organization, from the API and from syncs, however many run at once. Match each event to the job you started with
data.job_id. See Many jobs at once.
- Set up in Studio or with the API: add endpoints, send test events, read delivery logs and resend failed deliveries on the new Webhooks page in Captain Studio, or with the Endpoint management routes. The Captain MCP server adds
captain_webhook_setup and captain_webhook_events.
- Reliable delivery: failed deliveries are retried for about 28 hours, and filters limit an endpoint to certain events, collections, syncs or sources. Each event’s payload is documented under Webhook events.
