title: "Trigger an Outbound Call by API Trigger Node"
description: "Initiate an outbound call using an API Trigger node UUID"
openapi: "POST /api/v1/public/agent/{uuid}"
---

Use this endpoint when you want to execute a workflow through an [API Trigger node](/voice-agent/api-trigger).

The `uuid` comes from the API Trigger node in your agent. Add the node to your workflow and copy its auto-generated `trigger_path`.

Use `workflow_run_id` from the response to later [retrieve call details](/api-reference/calls/get-run), recordings, and transcripts.

Pass `initial_context` to inject runtime data as template variables into the agent's prompt. See [Using initial context](/api-reference/calls#using-initial-context).

Pass `telephony_configuration_id` to route the call through a specific telephony configuration instead of your organization's default. The id is shown on each row in **Telephony configurations** (`https://app.dograh.com/telephony-configurations` for hosted or `http://localhost:3010/telephony-configurations` for local).

<Note>
This route expects an API Trigger node UUID (`trigger_path`). Do not pass a workflow UUID here. If you want to execute by workflow UUID, use [Trigger an outbound call by workflow UUID](/api-reference/calls/trigger-workflow) instead.
</Note>

<Note>
Your telephony provider must be configured before outbound calls will connect. See [Telephony](/integrations/telephony/overview) for setup instructions.
