Abstract: A first request to send a message via a communication channel of multiple communication channels is receiving at a software-as-a-service (SaaS) platform via a first application programming interface (API) call. The first request identifies a content template stored at the SaaS platform. The content template specifying a dynamic variable for at least a portion of the content of the message is obtained based on the first request. The message is prepared based on the first request and the content template. The content of the message contains a value for the dynamic variable. The prepared message is sent to the recipient device via the communication channel.
