project.member_role_changed

POST

A project member’s role changed.

• Signed with Standard Webhooks (the headers below). Verify the signature over the raw body before parsing it — the recipes are in the developer docs’ Webhooks guide.
• Answer any 2xx within 20 s. Anything else, or no answer, is retried: 8 attempts over about 21 h.
• 410 Gone disables the webhook.
