REST based One API

Connect’s One API enables businesses to implement communication through multiple channels with a one-time integration effort. Using the One API, you will be able to send and receive messages on both WhatsApp and SMS without the overhead of programming individual channels. One API makes your implementation future proof as we continue to add support for additional channels to the Connect platform.


  • Enable multiple communication channel access without individual integration effort per channel

  • Reduce cost of development with a single API implementation

  • Configure and enable encryption for secure messaging needs

  • Support high deliverability of messages using rules based channel failover between WhatsApp and SMS

  • Test and utilize new messaging channels as they become available on the Connect platform
