Green API

Overview

This node integrates with the Green API service to manage WhatsApp groups and messages. Specifically, for the Group - Remove Admin operation, it removes admin rights from a specified participant in a WhatsApp group. This is useful when you want to revoke administrative privileges from a group member without removing them from the group.

Practical scenarios include:

• Moderating group roles by demoting admins who no longer need elevated permissions.
• Automating group management workflows where admin status changes based on external triggers or conditions.

Properties

Output

The node outputs a JSON object representing the response from the Green API after attempting to remove admin rights. This typically includes success confirmation or error details related to the operation.

No binary data output is involved in this operation.

Dependencies

• Requires an active Green API account with valid credentials (instance ID and API token).
• The node uses HTTP POST requests to the Green API endpoints.
• Proper configuration of the Green API credentials within n8n is necessary.

Troubleshooting

• Common issues:

  • Invalid or missing Group ID or Participant Chat ID can cause failures.
  • Insufficient permissions or incorrect API credentials may result in authorization errors.
  • Network connectivity problems can prevent successful API calls.

• Error messages:

  • Errors like Failed to remove admin: <error message> indicate issues returned by the Green API.
  • File reading errors do not apply here but are relevant for other operations involving files.

• Resolution tips:

  • Verify that the Group ID and Participant Chat ID are correctly formatted and exist.
  • Ensure the API credentials are valid and have the required permissions.
  • Check network access and retry if transient errors occur.
