3CX Http API User Guide

1.Introduction

Our 3CX Http API makes it easy to integrate phone functions into your applications. By abstracting the complexities of the 3CX Call Control API into a simple-to-use API, even a novice programmer can integrate with 3CX.

1.1. What are the API Methods?

Our Http API makes it easy for even novice programmers to incorporate 3CX phone functions into your applications. With over a dozen methods to choose from, HTTP API is perfect for helping create your custom 3CX solution.

A view of all the API methods is displayed in the Appendix section of this manual.

Some of the methods that API includes are as mentioned below:

• Barge-in
• Drop Call
• Listen
• Make Call
• Make Call Play File
• Outbound Caller ID
• Park Call
• Record
• Transfer
• Whisper

1.2. How does it work?
The API is self-documenting. To display the syntax for a given method, simply call the method without any parameters and the API will return the required syntax along with examples. This makes working with the API simple. For example, to display the syntax for the WhisperTo method, simply call the method by browsing to http://localhost:5505/WhisperTo.aspx and the following table will display:

1.3. What’s New?
Our API extends the existing 3CX API methods, and adds new API methods. For example, our MakeCall method has the following additional features:

• All parameters are validated to ensure extensions, queues, ring groups, and shared parking orbits exist

• Enforces security by requiring a PIN for extension parameters

• Adds an optional parameter to swap the outbound Caller ID before placing a call

• Supports a default tenant

• Adds an optional parameter to override the default tenant

Step 4: Download the VoIPTools 3CX Relay (if required)

3CX permits one 3rd party application to communicate with the 3CX server at a time. To overcome this limitation, VoIPTools created the 3CX Relay Service. The Relay is a lightweight application that is installed directly on the 3CX server. The Relay exposes the 3CX Call Control API (and other VoIPTools services) to all our applications, and manages requests and events between by VoIPTools products and 3CX. The Relay also makes it possible to install our VoIPTools products on a remote server (including over the internet).

1. If you have not previously installed the Relay on your 3CX Server, you can download the Relay installer by clicking on the Download Relay button. The Relay must be installed directly on the 3CX server.

2. If you are installing 3CX Http API directly on the 3CX server, you can install the Relay simply by clicking the Install/ Upgrade Relay button and following the Relay install instructions.

If you have already installed the Relay, you need not install it again unless a newer version is required.

Step 5: Test Relay Settings

1. In the Relay Services Host field, enter “localhost” if installing 3CX Http API on the 3CX server. If 3CX resides on a different server, enter the IP address or FQDN of the 3CX server.

2. In the Relay Services Port field, enter the value as 8700

The default port number is 8700.

3. Click Test Relay Settings to confirm 3CX Http API can communicate with the Relay services running on the 3CX server.
