TwHello Developer Documentation

The TwHello IDE allows you to layout the flow of an IVR app with a drag-n-drop "workflow" editor by organizing and linking "elements". Our TwHello JavaScript Library will construct the TwiML and respond to Twilio.

Workflows are the apps you develop with the TwHello IDE. A workflow is made up of interconnected elements. Element logic is programmed using JavaScript. One workflow can be linked to many Twilio accounts and phone numbers.

The Basics

Setting up a workflow with a Twilio phone number is done in a few easy steps:

  1. Develop a Workflow with the TwHello IDE.
  2. Connect your TwHello account to a Twilio account.
  3. Deploy the app by linking the Twilio number to the workflow.
  4. In the Twilio admin, enter the callback URL in the field labelled "Voice Request URL".
  5. Call the number, test the app and repeat.

Simple Auto-Dialer  

The Auto-Dialer is a simple service to initiate voice calls or send messages to a list of phone numbers. Simply upload a CSV or tab-delimited list and TwHello will dial the numbers over a designated hour. It is free to initiate calls. TwHello call management is not required.

JavaScript Library  

The JavaScript library contains the classes and methods you will use to communicate with Twilio. Instead of building TwiML, you will program in JavaScript. The JavaScript library supports every feature of Twilio.

The REST API is how your external systems can communicate with your TwHello apps. Primarily, the REST API provides access to our database and file storage services. We will expand the REST service in the future.
