role.* events

A role is deleted. Only roles no collaborator currently holds can be deleted.

When this fires

A role that no collaborator currently holds is deleted. A role still assigned to someone cannot be deleted at all; the database refuses it.

Caveats

  • Deleting is restricted to the role's creator, unless the caller owns the team: a team owner can delete any role in their team, including the default admin, manager and viewer roles. The dashboard hides the action for roles you did not create; the API and MCP surfaces do not.

Related events

  • role.created: first event in the lifecycle.
  • team.member.role_changed: emits for explicit role re-assignments.

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'role.deleted' required

The event name, always role.deleted 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.
