Initiate Call
The simplest way to initiate a call programmatically. 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, recordings, and transcripts. Pass initial_context to inject runtime data as template variables into the agent’s prompt. See 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 at app.asisso.com/telephony-configurations.
Your telephony provider must be configured before outbound calls will connect. See Telephony for setup instructions.
