It accepts a media payload in JSON format, which can be either a Data URL or a base64 string with an optional mimetype.

Use Case Examples

  1. Uploading a base64 encoded image to a WhatsApp session to share product photos with customers.
  2. Sending a video file to a group chat for marketing or informational purposes.
  3. Uploading an audio message to a contact for personalized communication.

Troubleshooting

  • Ensure the session ID is correctly specified or available in the incoming item; otherwise, the node will throw a 'Session is required' error.
  • The upload payload must be a valid JSON object containing either a Data URL or a base64 string; invalid JSON will cause an error.
  • If the API request fails, check the retry options and network connectivity.
  • Common error messages include invalid session ID, malformed upload payload, or API request failures. Verify credentials and payload format to resolve these issues.
