--- title: "Overview" description: "Initiate outbound calls and trigger agents via the API" --- | Method | Endpoint | Quick Link | |---|---|---| | `POST` | `/public/agent/{uuid}` | [Trigger an outbound call by API Trigger node](/api-reference/calls/trigger) | | `POST` | `/public/agent/workflow/{workflow_uuid}` | [Trigger an outbound call by workflow UUID](/api-reference/calls/trigger-workflow) | | `GET` | `/workflow/{workflow_id}/runs/{run_id}` | [Retrieve call details](/api-reference/calls/get-run) | | `GET` | `/public/download/workflow/{token}/{artifact_type}` | [Download recordings and transcripts](/api-reference/calls/download) | | `POST` | `/telephony/inbound/{workflow_id}` | [Inbound call webhook](/api-reference/calls/inbound) | ## Choose the right public call route Dograh exposes two public outbound call route families. They are **not** interchangeable, even though both path parameters look like UUIDs. | Use this when | Production route | Test route | Identifier you pass | |---|---|---|---| | You added an **[API Trigger node](/voice-agent/api-trigger)** to the workflow and want to call that trigger | `/public/agent/{uuid}` | `/public/agent/test/{uuid}` | The trigger UUID (`trigger_path`) from the API Trigger node | | You want to execute the workflow by its stable **Agent UUID** instead of a trigger node | `/public/agent/workflow/{workflow_uuid}` | `/public/agent/test/workflow/{workflow_uuid}` | The workflow UUID from the agent's **[Agent UUID](/configurations/agent-uuid)** field | Do not pass a workflow UUID to `/public/agent/{uuid}` and do not pass a trigger UUID to `/public/agent/workflow/{workflow_uuid}`. Dograh treats these as different identifier types and the request will fail if you mix them up. Once Dograh resolves the target agent, both route families behave the same: - They accept the same request body - They return the same response shape - They validate the same `X-API-Key` organization boundary - They use the same telephony configuration selection rules If you specifically need the API Trigger route, see [Trigger an outbound call by API Trigger node](/api-reference/calls/trigger). To execute by workflow UUID, see [Trigger an outbound call by workflow UUID](/api-reference/calls/trigger-workflow). ## Using initial context `initial_context` passes runtime data into the agent at call time. Values are available as template variables in your agent's prompt using double-brace syntax. ```json { "initial_context": { "customer_name": "Jane", "appointment_date": "March 15" } } ``` Your agent prompt can then reference `{{customer_name}}` and `{{appointment_date}}` and they will be substituted when the call starts. ## Run status values | Status | Description | |---|---| | `pending` | Call queued but not yet connected | | `in_progress` | Call is live | | `completed` | Call ended normally | | `failed` | Call failed before or during execution |
