Interact with Go WhatsApp Web MultiDevice API

Actions23

Overview

This node integrates with the Go WhatsApp Web MultiDevice API, enabling users to manage WhatsApp messaging programmatically within n8n workflows. Specifically, the Update Message operation under the Message resource allows users to modify the content of an existing WhatsApp message by specifying the target chat and message ID.

Common scenarios for this node include:

  • Correcting or updating sent messages in private or group chats.
  • Automating message edits based on external triggers or data changes.
  • Managing conversations dynamically without manual intervention.

For example, a user could automate updating a status message in a group chat whenever a related data source changes, ensuring that the information shared is always current.

Properties

Name Meaning
Phone Number or Group ID The phone number (for private chats) or the Group ID (for group chats) where the message resides.
Message ID The unique identifier of the message to be updated.
New Message The new text content that will replace the existing message content.

Output

The node outputs JSON data representing the result of the update operation. This typically includes confirmation details such as success status and possibly metadata about the updated message. The exact structure depends on the API response but generally confirms that the message was successfully modified.

No binary data output is indicated for this operation.

Dependencies

  • Requires an active connection to the Go WhatsApp Web MultiDevice API.
  • Needs an API authentication credential configured in n8n (an API key or token).
  • The node expects the base URL of the API to be set via credentials.
  • Proper permissions on the WhatsApp account to edit messages are necessary.

Troubleshooting

  • Invalid Phone Number or Group ID: Ensure the provided identifier matches the format expected by the API and corresponds to an existing chat.
  • Message ID Not Found: Verify that the message ID exists in the specified chat; otherwise, the update will fail.
  • Authentication Errors: Confirm that the API credentials are valid and have not expired.
  • API Rate Limits: Frequent updates might hit rate limits imposed by the service; consider adding delays or error handling.
  • Error Messages: If the node returns errors, check the error message for clues—common issues include invalid parameters or network connectivity problems.
