Place an outbound call

Use the SDK to place a test outbound call from a specific agent to a phone number. This is the same endpoint used by the Test Call button in the Decibyl UI.

Prerequisites

• A Decibyl API key exported as DECIBYL_API_KEY
• A published agent (you need the agent ID)
• A configured telephony provider — see Telephony for Twilio, Vonage, and other setups

Place the call

from decibyl_sdk import DecibylClient
from decibyl_sdk._generated_models import InitiateCallRequest

with DecibylClient(api_key="YOUR_API_KEY") as client:
    client.test_phone_call(
        body=InitiateCallRequest(
            workflow_id=123,
            phone_number="+14155551234",
        )
    )

import { DecibylClient } from "@decibyl/sdk";

const client = new DecibylClient({ apiKey: "YOUR_API_KEY" });

await client.testPhoneCall({
    body: {
        workflow_id: 123,
        phone_number: "+14155551234",
    },
});

Inspect the run

Every call creates a run you can inspect afterwards. See Calls & runs for what’s tracked, or use the Runs API to list and fetch runs programmatically.

Bulk campaigns

For placing many calls at once (say, from a CSV), use Campaigns rather than looping over test_phone_call — campaigns handle pacing, retries, and progress tracking.
