Powering Your Apps and Services

The process of powering your mobile and web apps with a voice API is fairly straightforward: 1st – your app sends an HTTP request to Flowroute; 2nd – we initiate an outbound call; 3rd – the user receives the telephone call. You can use our API to enhance a number of app tasks such as:

  • SMS and MMS – Use the Flowroute Messaging API to reach customers fast.
  • Verification – With SMS and calling technology, you can verify any end-users number quickly and easily.
  • Voice – Users have more ways to connect from app to app, or app to phone, thanks to our powerful SIP Trunking capabilities.

With our phone call API, end-users have anonymous calling capabilities, meaning they can make or receive calls within the application, and not have to share any personal information or phone numbers. We are also able to provide a superior security level, giving you the tools to aggressively prevent fraud. With cost-effective and quality SIP Trunking services, we help integrate calls, data, and videos with ease.
