Use the media node to upload, retrieve, or delete media.
To send media such as images, documents, audio or video you must first Upload the Media and then Send it.
When a media message is sent, the media is stored on the WhatsApp servers for 14 days. We also store media on our servers for 14 days. If a user makes a request to download the media after 14 days, the user will be notified that the media is unavailable (as the media will be removed).
If you use the media upload process rather than linking to a media URL, the file must be uploaded to the media volume. Once the upload is complete, you can send a message using the media ID.
The application processes the media that is uploaded before it's sent to the server. While the maximum file size for media that can be uploaded to the media node is 64MB, there are post-processing limits for the various media types outlined in the Post-Processing Media Size table.
Media storage is handled by 360dialog. If the media volume gets full, message sending will start to fail.
