team.member.role_changed

project_id is always null for team events.

When this fires

A collaborator's role within the team changes — promoted, demoted, or moved between custom roles.

Field reference

Field	Type	Notes
`id`	string ULID	Unique event id, prefixed `evt_`. Use for idempotent processing.
`type`	string	Always `team.member.role_changed` for this event.
`created_at`	ISO 8601 timestamp	Server-side emission time.
`api_version`	string	Webhook API contract version.
`project_id`	null	Always `null` — account-level event.
`data.team_id`	string UUID	Team the collaborator belongs to.
`data.user_id`	string UUID	User id of the collaborator whose role changed.
`data.role_id`	string UUID, nullable	Currently always `null` — the team's pivot role is not carried on this event. Read the role from `GET /v1/teams/{team}/members/{member}`.

Caveats

For ability detail behind a role id, listen for role.updated or pull the role definition from the API.
This event covers the team-level role on the team_user pivot only. Groups carry permissions rather than roles, so a change to group membership emits group.members_synced instead and never this event.

team.member.joined — predecessor in the lifecycle.
role.updated — emits when the role definition itself changes.
