The Team Behind the RCS Knowledge Hub
The RCS Knowledge Hub is an open-access knowledge base created and maintained by GatewayAPI — helping businesses understand, plan and launch RCS Business Messaging.
Who We Are
GatewayAPI is a global CPaaS and SMS gateway that lets businesses send messages to their customers through a simple API.
GatewayAPI is owned and operated by ONLINECITY.IO.
Why GatewayAPI runs this hub
RCS Business Messaging is new to many businesses. We created the RCS Knowledge Hub to collect what we know about RCS in one open place, so teams can understand it, plan for it and launch it.
Why We Built This Hub
Open knowledge
Every guide on the hub is free to read, with no sign-up or paywall between you and the answer.
Built on real deployments
The content draws on what the GatewayAPI team sees when businesses set up and send RCS messages.
Vendor-neutral guidance
We explain how RCS works as a standard, so the guidance is useful whichever provider you choose.
