A voice API is a programming interface that allows businesses to integrate voice calling with any application or website. In the background, it connects the public switched telephone network (PSTN) and online applications. This means that using voice APIs, you can control calls with software, create customised call flows, and more.
For instance, you can connect voice calling to your CRM and directly make outgoing calls from the CRM software using voice API.
Safeguard customers’ privacy: Mask their number from customer service agents
Personalise experience: For instance, you can set up a customised IVR for a specific set of customers who call from a specific location or use a particular product of yours
Enhance tracking: Automatically record calls, capture metadata like caller number, call length etc.
Improve customer experience: Automatically route calls to the right agent based on predefined attributes

The APIs are designed according to REST principles, enabling you to connect your cloud telephony to any application on the World Wide Web. Exotel's REST APIs are served over HTTPS and HTTP.
Yes, once Exotel’s cloud telephony is connected to your contact centre management system using the voice API, you can also receive calls right from within the app/website.
Absolutely. Exotel's REST APIs are served over HTTPS and HTTP, but we recommend the former for additional security. Each API request will contain request headers that include your access token to authenticate the request. HTTP requests to the REST API are protected with HTTP Basic authentication, with your Exotel API key as the username and your API token as the password.
