Send Media & File

POST

Send image, video, audio, or document with an optional caption. Always use type media. Media must be a public HTTPS URL. The message param is the caption shown with the media.

Only delivers if the customer messaged you within the last 24 hours. Outside that window, use Meta Templates. The message param is the caption under the media. Set filename when sending documents.
