You can now send media content such as images, videos, PDFs and audio files up to 5mb in size over WhatsApp using the Twilio API. This feature is similar to sending an MMS and requires including a MediaUrl parameter in your API requests. The media content is currently only supported in Session Messages and must be re-established with an inbound message after expiration. This update enables businesses to engage with customers on messaging channels they prefer, using rich contextual conversations. It also provides various use cases such as sending boarding passes, tickets, or confirming package delivery. However, there are differences between MMS and WhatsApp media messages, including file type support. The Twilio API for WhatsApp continues to be enhanced, providing developers with new opportunities to build innovative applications.
