change_request.updated
A change request's fields change.
When this fires
Any of the request's own columns change: the title, the description, the reason, the stakeholder, the baseline, the impact fields, the priority; or the records it touches are set. A status move raises its own event, not this one. changes holds one entry per column that changed, each with the value before and after; when the records touched changed, changes.affected lists them as type:id before and after.
Related events
change_request.status_changed: the move that is deliberately not an update.
Ability to subscribe
A token needs this to subscribe an endpoint to the event.
Header Parameters
t=<unix seconds>,v1=<hex>: the HMAC-SHA256 of "<t>.<raw body>" under the endpoint's secret. Verify it before acting, and refuse a t more than 300 seconds from now.
The event's ULID, bare. The envelope's id is the same ULID prefixed evt_, so strip the prefix before comparing. Deduplicate on it: a retry carries the same id.
The event name, the same as the envelope's type.
Always application/json.
Always ZuseBifrost-Webhooks/1.0.
Payload
JSONWhat Zuse Bifrost posts to your endpointapplication/json
The signed JSON envelope posted to your endpoint.
The envelope every event is delivered in.
Responses
2XXAny success status
Your endpoint acknowledged the delivery. Any 2xx status within 30 seconds marks it delivered; the response body is ignored.
defaultAny other status
Any other status, a connection failure, or no answer within 30 seconds counts as a failed attempt. The delivery is retried 8 times, after 10 seconds, 30 seconds, 2 minutes, 10 minutes, 1 hour, 6 hours, 1 day, 3 days; the last failure dead-letters it, and it can be retried from Settings → Webhook Deliveries or POST /v1/webhook-deliveries/{delivery}/retry. After 20 consecutive failures the endpoint is paused until it is resumed.
