Quickstart - Place an Outgoing Call

Overview

The purpose of this guide is to help you create a working sample that uses the Make Voice Call activity.

This working sample enables you to quickly verify the connection to your Twilio resources and get familiar with the activity's input/output datatypes.

After completing the steps in this guide, you'll have an automation sequence that does the following:

1. Establishes a connection to your Twilio resources (Twilio Scope).
2. Place an outgoing phone call (Make Voice Call).

Prerequisites

Before you begin:

1. Complete the Twilio Setup steps.

Steps

1. First, add an Twilio Scope activity and set the values for the input parameters like in the screenshot below. In the sample workflow above, you can see that I got the values for these parameters from variables. Here's a short description of the activity’s parameters:

   • Account Sid (String) - Your Account SID from your project dashboard.
   • API Key Sid (String) - API Key SID to work with your Twilio project. API Keys can be provisioned and revoked through the Twilio Console.
   • API Key Secret (String) - API Key Secret to work with your Twilio project. API Keys can be provisioned and revoked through the Twilio Console.
     
     

     

     
     

2. Add the Make Voice Call activity which can be used to place a phone call. The parameters of this activity are:

   • From (String) - The Twilio phone number in E.164 format.
   • To (String) - The phone number to call, in E.164 format, e.g. [phone].
   • Say (String) - Text that is read when the call is answered.
   • PlayAudio (String) - The URL of an audio file that Twilio will play when the call is answered.
   • TwiML (String) - Instructions in the form TwiML that explains what should happen when the other party picks up the phone. Learn more about TwiML.
     
     

     

     
     
3. Click Run and verify the call goes through.
