Sampled — shipped under file-level sampling, not individually fact-checkedcommunity attestations: 0✓ / 0✗
Steps
In Portainer, select Services, open the target service, and toggle Service webhook on
Copy the generated webhook URL (https://<portainer>/api/webhooks/<uuid>)
Configure your registry (e.g. Docker Hub) or CI pipeline to POST to that URL on a push/build event to redeploy with the latest image of the same tag
To roll to a different tag instead, POST with a ?tag=<newtag> query parameter
For Business Edition, pass additional environment variables as query parameters (e.g. ?SERVICE_TAG=development) referenced in the compose file as ${SERVICE_TAG:-stable}
Known gotchas
Service webhooks only work on non-Edge environments — the Edge Agent's tunnel is opened on-demand, so there's no way to expose a permanent webhook endpoint for it
No API authentication header is needed to trigger the webhook — the URL's UUID itself is the secret, so treat it like a credential
A successful trigger returns HTTP 204 No Content; anything else indicates a configuration or permission problem, not an application error
