Create an inbound agent

Create an inbound agent so a phone number can be answered by one of your agents.

Create an inbound agent so a phone number can be answered by one of your agents.

agent_id must name an agent in your organisation; any other value answers 404. The application's webhook endpoints are derived server-side from that agent — they are Graine's own call-handling URLs and are neither accepted as input nor returned.

Creating the application does not yet make a number ring it: hand the returned application_sid to Graine to have one of your numbers pointed at it. Once linked, the number shows is_inbound: true in GET /v2/phone-numbers.

Inbound agents are not available on every carrier. If your organisation is on one that does not support them the request answers 400 — GET /v2/providers reports what your organisation is configured for.

Rate limit: 1000 requests per minute per organization (bucket default). Exceeding it returns 429 with Retry-After; the X-RateLimit-* response headers report your remaining allowance on every call.
