Sending media messages with Twilio's WhatsApp API is now possible and can be done just as quickly as sending text-based messages. To get started, set up a Twilio account, .NET Core 2.2 SDK, and WhatsApp Sandbox Channel. Create a new .NET Console application, add the Twilio NuGet package, and initialize the Twilio REST client with your Account SID and Auth Token. Send a message by calling the MessageResource.Create method, passing in the sender's and recipient's WhatsApp phone numbers, a text-based message body, and the media URL. The project can be restored from GitHub and built to run in no time, sending a media message to your phone. Note that there are differences between MMS and WhatsApp media messages, such as file type support and messaging sessions.
