What's New in RCS
We fixed an issue where the rcsMoMessage wrapper field was not being returned for MO messages and read and delivery receipts. This release also included new and renamed fields to make the information contained in MO messages, read receipts and delivery receipts more clear. For details see MOs, Read Receipts and Delivery Receipts.
We updated RCS MO forwarding to support free text and postback responses with the addition of two new parameters in an MO: content and postBack. These parameters indicate the type of RCS message when a user returns a text response keyword (content) or clicks an action or suggestion sent in the message (postBack). For details see Receive an RCS MO.
