title: "Trigger an Outbound Call by Workflow UUID"
description: "Initiate an outbound call using a workflow's stable Agent UUID"
openapi: "POST /api/v1/public/agent/workflow/{workflow_uuid}"
---

Use this endpoint when you want to execute a workflow directly by its stable Agent UUID instead of through an API Trigger node.

The `workflow_uuid` is the workflow's Agent UUID. It is different from an API Trigger node's `trigger_path`.

To find and copy the Agent UUID in the UI, see [Agent UUID](/configurations/agent-uuid).

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 a workflow UUID. Do not pass an API Trigger node UUID here. If you want to execute via an API Trigger node, use [Trigger an outbound call](/api-reference/calls/trigger) instead.

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