I am currently working on integrating rocket chat with WhatsApp using the Chat-Api’s unofficial API. While I know that rocket chat integrates easily with Twilio’s official WhatsApp broker, Twilio’s cost per message can easily add up. So that’s my main motivation with this project.
The project is currently under development, and I can exchange text messages between the two platforms. The multimedia message exchange is currently under development though as I’m having a bit of trouble with Chat-Api.
Anyways, here’s my project on Github.
