project.* events

Any mutable project field changes.

When this fires

Any mutable field on a project changes: display name, handle, description, terms, privacy text, or other dashboard-editable settings. State-flag transitions (archive, restore) emit dedicated events instead.

Caveats

  • The changes block contains only the fields that mutated; unchanged fields are not included.
  • changes can report fields the project snapshot does not carry: description, terms, privacy, metrics, banner_url, and photo_url. Read the new value from changes[field].to, or fetch the project from the project endpoint.
  • POST /v1/projects/{project}/archive and /restore emit the dedicated project.archived / project.restored events, but a plain PATCH that sets active reports the flip in changes.active on project.updated instead. Handle both.
  • Connecting or disconnecting an installation does not trigger project.updated; it emits connector.connected / connector.disconnected.

Related events

  • project.created: predecessor for any project.updated event.
  • project.archived, project.restored: dedicated state-transition events.

Headers

SB-Signaturestring required

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. During a secret rotation a v0= signature under the previous secret may precede v1=.

SB-Event-Idstring required

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.

SB-Event-Namestring required

The event name, the same as the envelope's type.

Content-Typestring required

Always application/json.

User-Agentstring required

Always Subscriby-Webhooks/1.0.

Payload

idstring required

A ULID unique to the event, prefixed evt_. Every retry carries the same id, so it is the key to deduplicate on.

type'project.updated' required

The event name, always project.updated here.

created_atstring date-time required

When the event was emitted, server time, ISO 8601.

api_versionstring required

The contract version of the payload shape, 2026-05-01 today. A breaking change to a shape ships under a new version.

project_idstring uuid nullable required

The project the event belongs to; null for team-scoped and billing events.

Response

Your endpoint acknowledged the delivery. Any 2xx status within 30 seconds marks it delivered; the response body is ignored.

Changes

Webhooks have no change history: a webhook is keyed by its event name rather than a path and method, so no recorded change can name it.
