}Authorizations
A Contact Button scoped bearer key. Send Authorization: Bearer <token>.
Token abilities are enforced independently of workspace membership; both checks must pass.
Interactive MCP clients use registered OAuth applications, Authorization Code + PKCE,
audience-bound tokens, and explicit workspace grants. Personal Sanctum tokens remain supported.
Headers
Stable 8–120 character key for safe mutation retries.
8 - 120Path Parameters
Body
Unexpired opaque quote ID returned by phone-number search.
120Public UUID returned by a call-flow operation.
Send only after the human explicitly approves the quoted recurring and upfront charges.
