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:
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:

The following section guides you through a detailed walk-through of the installation process.
Step 1: Download 3CX Http API
You can check for the software download link included in your order confirmation email. As an alternative, you can also find the link from your order history on our website.
Step 2: Extract the installer from the downloaded .zip file
The file you downloaded in the above step is a compressed .zip file.
1. Position the mouse on the zip file and right-click.
2. From the popup menu, select Extract All to extract the software.
Step 3: Start the installation process
1. From the extracted folder, find the file VoIPToolsHttpAPIInstaller.exe
2. Double-click the file to start the VoIPToys Setup Wizard.

1. If you are installing 3CX Http API on a 3CX Cloud (Multi-tenant) server, an additional screen will display with a combo box containing a list of all installed tenants. Select the correct tenant and continue.
2. If you are installing 3CX Http API on a separate server and pointing it to a 3CX Cloud server, you will need to tell the installer the name of the specific tenant desired. Start the installer from a command window and include an additional parameter: tenantname=
For example: 3CXHttpAPI.exe tenantname=the3CXtenantname
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.
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
3. Click Test Relay Settings to confirm 3CX Http API can communicate with the Relay services running on the 3CX server.
4. If the 3CX Http API is successfully able to communicate with the Relay services that run on the 3CX server, Success message box appears. Click OK
5. Click Next to continue the installation.
Step 6: Run the Application
When the installation is complete, click Run Application button.
Step 7: Registration
Registration is required to authorize your license key. Registering also makes it possible for VoIPTools to provide a replacement key if your license key is ever lost. Also, it enables VoIPTools to notify you of any product updates, and reminders if your key is reaching the renewal date.
Instructions to Register the software:
1. On the Settings menu, and in the License tab, enter your registration information in all the fields (Note the red dot denotes a required field).
2. Click Register.
