Introduction

Vtiger CRM offers APIs to track calls made from your telephony system. Using these APIs, you can integrate your telephone service provider with Vtiger CRM and use the following features:

• Click-to-call
• Incoming call popup
• Call logging in CRM
• Recording link

With these features, you can:

• Easily trigger popups in the CRM for incoming calls
• Update the recording URL, call status, and call notes for a phone call record in the Phone Calls module

 

Benefits of Phone Calls API

Here are some benefits of phone calls API:

• Manage all phone calls within the CRM system.
• Initiate calls directly from the CRM with a simple click.
• Provide better customer experience with personalized interactions.
• Gain insights into call performance.
• Automatic route calls to the appropriate agents based on skills, availability, and customer preferences.

Configuring the Phone Calls Module

Follow these steps to configure the Phone Calls module: 

1. Log in to the CRM.
2. Go to the main Menu.
3. Go to Essentials.
4. Go to Conversations.
5. Click the Phone Calls module.
6. Click Settings (wheel icon).
7. Select Provider Configuration.
8. Click Add Gateway.
9. Select Generic gateway from the dropdown.
10. Click Save.

After you save this gateway, the screen will display the Vtiger Secret Key, which should be passed in the header with the key X-VTIGER-SECRET for every API.
Note: Ensure your CRM user’s Office Phone is configured for this. Without the Phone Office number, the call pop-up will not appear inside the CRM.

Configuring Outgoing Calls for a Gateway

​​

After you select the Generic Gateway type, follow these steps to configure outgoing call details:

1. Add the telephony services’ REST API URL to track the calls.
2. Select either POST or GET to send the request. By default, the content type is set to FORM.
3. Authenticate your service by providing a username and password
   1. Or continue without any authentication.
4. Add the parameters that you need to pass to the endpoint.
    

​​​​URL-based authorization for outgoing calls

You can provide URL-based authorization for outgoing calls in the Generic Gateway configuration. 

• The URL will return a response used when sending an outgoing call request.
• For example, the token URL will return the access_token in response. This access_token can be used in the request header or parameter.

Setting up Workflows from Generic Phone API

• Using the Generic Phone API, you can now set up a workflow to automatically send an email or a WhatsApp message to a customer when an incoming call is missed. 
• The Generic Phone API triggers a workflow for every phone call status update or any other update for all phone call gateways.

Note: All of them use the below endpoints.
