Message → Send Media Base64

AI-generated

Overview

This node operation sends a media file encoded in base64 format to a specified WhatsApp contact. It supports various media types such as audio, document, image, voice message (PTT), and video. The media is sent with an optional caption and requires specifying the MIME type and file name. This operation is useful for automating the sending of media files directly from base64 data, for example, sending images, videos, or documents to WhatsApp contacts without needing to upload files separately.

Use Case Examples

  1. Sending a base64 encoded image to a WhatsApp contact with a caption.
  2. Sending a PDF document encoded in base64 to a contact as a document file.
  3. Sending a voice message encoded in base64 as a PTT (Push-to-Talk) message.

Troubleshooting

  • Ensure the 'To (Contact)' field is correctly formatted as phone_number@s.whatsapp.net.
  • Verify that the base64 data includes the correct data URI prefix and is properly encoded.
  • Check that the MIME type matches the actual media content to avoid sending errors.
  • If the message fails to send, verify the API credentials and network connectivity.
  • Common error messages may include invalid contact format, unsupported media type, or authentication failures. Resolving these involves correcting input formats and ensuring valid credentials.
