Summary

Send an image, video, document, or audio file to a WhatsApp recipient through the 360dialog Messaging API. Provide a recipient phone number, a Business-Scoped User ID, or both; the phone number takes precedence when both are supplied.

Inputs

  • To (Phone Number) — Recipient phone number in international format. The node strips plus signs, spaces, hyphens, and parentheses, then requires digits only.
  • Recipient (User ID) — Recipient Business-Scoped User ID (BSUID), for example BR.13491208655302741918. Must match the BSUID format; at least one recipient identifier is required.
  • Media Type — File type to send: audio, document, image, or video. Defaults to image.
  • Media URL (required) — Publicly reachable HTTPS URL for the file. Signed or expiring URLs may fail.
  • Caption — Optional caption for image, video, or document media. Not used for audio.
  • Filename — Optional filename shown to the recipient when sending a document.

Output shape

A list of output items, one per input item, each containing the 360dialog response as JSON.

The response fields are preserved, with messageId, waId, and userId added from the first message and contact when present. With Continue On Fail enabled, failed items contain an error field instead.

Set Media Type to Image, enter a public HTTPS Media URL, provide either recipient identifier, and optionally set Caption.

Example 2: Send a document with a displayed filename

Set Media Type to Document, enter a public HTTPS Media URL, provide a recipient identifier, and optionally set Filename and Caption.

Example 3: Send audio
