Does Genesys Cloud SMS support MMS?

MMS support coming soon

Yes, but only inbound MMS and only a select set of media types are displayed in the agent user interface. More specifically agents can receive and view .jpg, .png, and .gif media in the agent user interface. Genesys Cloud can receive other media types are but does not display them in the agent user interface. Agents cannot send media in messages.

If an end user sends unsupported media in a message, then the agent receives an indication that a media attachment was removed. If a user sends only media in a message, then Genesys Cloud notifies the agent that the message has no content.

While Genesys Cloud does not display certain media types in the agent user interface, those media types are indeed received by Genesys Cloud and are accessible via an API call. For more information, see Conversations API in the Developer Center.
