Reference: https://docs.tryenvoy.ai/api-reference/endpoints/calls/create ## Authentication - `Authorization` header (bearer token, required) — Bearer authentication of the form `Bearer `, where token is your auth token. ## Servers - `https://tryenvoy.ai/api/v1` (Production, default) - `https://staging.tryenvoy.ai/api/v1` (Staging) ## Request ### Headers - `X-Organization-ID` (string, optional, nullable) - `Idempotency-Key` (string, optional) — A unique key (up to 255 printable ASCII characters, e.g. a UUID) that makes a retry of this request safe. Envoy stores the response for 24 hours; a retry with the same key and the same request returns it again with `Idempotent-Replayed: true` instead of running twice. The same key with a different request returns 422 `idempotency_key_reused`; while the first request is still running, 409 `idempotency_key_in_progress`. 5xx and 429 responses are not stored. ### Body (application/json) This endpoint expects a CallCreateRequest. - `phone_number` (string, required) — Phone number to call (E.164 format) - `load_id` (string, optional, nullable) — Load ID associated with this call - `template_id` (string, optional, nullable) — Prompt template ID - `voice_agent_id` (string, optional, nullable) — Voice agent ID (alternative to template) - `call_type` (string, optional, nullable) — Agent type: LOAD_BOOKING, ELP, or None - `template_variables` (map from string to any, optional) — Variables for the template/agent ## Response ### 201 Successful Response - `id` (string, required) - `status` (enum, required) - Allowed values: `SCHEDULED`, `PENDING`, `AGENT_ASSIGNED`, `IN_PROGRESS`, `COMPLETED`, `FAILED`, `CANCELLED`, `VOICEMAIL`, `NO_RESPONSE`, `TRANSFERRED` - `call_time` (datetime, required) - `created_at` (datetime, required) - `updated_at` (datetime, required) - `call_direction` (enum, optional, nullable) - Allowed values: `INBOUND`, `OUTBOUND` - `phone_number` (string, optional, nullable) — Customer phone number (derived from direction) - `to_number` (string, optional, nullable) - `from_number` (string, optional, nullable) - `call_start_time` (datetime, optional, nullable) - `call_end_time` (datetime, optional, nullable) - `call_type` (string, optional, nullable) - `load_id` (string, optional, nullable) - `organization_id` (string, optional, nullable) - `created_by_id` (string, optional, nullable) - `recording_status` (string, optional, nullable) - `load_number` (string, optional, nullable) ## Errors ### 401 Unauthorized Error Not authenticated - missing or invalid token/API key - `any` ### 403 Forbidden Error Insufficient permissions for this operation - `any` ### 409 Conflict Error `idempotency_key_in_progress`: a request with this Idempotency-Key is still running; retry later - `any` ### 422 Unprocessable Entity Error Validation Error; or `idempotency_key_reused`: this Idempotency-Key was already used for a different request - `detail` (list of ValidationError, optional) ### 429 Too Many Requests Error Rate limit exceeded - see Retry-After header - `any` ## Types ### ValidationError - `loc` (list of ValidationErrorLocItems, required) - `msg` (string, required) - `type` (string, required) - `input` (any, optional) - `ctx` (ValidationErrorCtx, optional) ### ValidationErrorLocItems ### ValidationErrorCtx ## Examples **Request** ```json { "phone_number": "string" } ``` **Response** ```json { "id": "call_00000000-0000-0000-0000-000000000000", "status": "SCHEDULED", "call_time": "2024-01-15T09:30:00Z", "created_at": "2024-01-15T09:30:00Z", "updated_at": "2024-01-15T09:30:00Z", "call_direction": "INBOUND", "phone_number": "string", "to_number": "string", "from_number": "string", "call_start_time": "2024-01-15T09:30:00Z", "call_end_time": "2024-01-15T09:30:00Z", "call_type": "string", "load_id": "load_00000000-0000-0000-0000-000000000000", "organization_id": "org_00000000-0000-0000-0000-000000000000", "created_by_id": "usr_00000000-0000-0000-0000-000000000000", "recording_status": "string", "load_number": "string" } ``` **SDK Code** ```python import requests url = "https://tryenvoy.ai/api/v1/calls" payload = { "phone_number": "string" } headers = { "Authorization": "Bearer ", "Content-Type": "application/json" } response = requests.post(url, json=payload, headers=headers) print(response.json()) ``` ```javascript const url = 'https://tryenvoy.ai/api/v1/calls';
