Once the upload is complete, you can send a message using the media ID. If you use the media upload process rather than linking to a media URL, the file must be uploaded to the media volume.Outgoing media is generally safe to be removed past 30 days, but you should employ a strategy that best suits your business. It is not safe to assume the media was downloaded simply based on the delivered and read receipts. If the media has been removed, the user will be notified that the media is unavailable. If a user makes a request to download the media after 14 days, the WhatsApp servers will request the same media file from the WhatsApp Business API client. When a media message is sent, the media is stored on the WhatsApp servers for 14 days.
