Send WhatsApp messages via Green API or trigger workflows on webhooks

Overview

The "Edit Message" operation of the Green API node allows users to update the text content of an existing WhatsApp message. This is useful when you need to correct or modify a previously sent message in a chat without sending a new message.

Common scenarios include:

Fixing typos or errors in a sent message.
Updating information in a message after it has been sent.
Changing the message content based on user interaction or workflow logic.

For example, if a user sends a message with incorrect details, this operation can be used to edit that message to reflect the correct information seamlessly.

Properties

Name	Meaning
Message ID	The unique identifier of the message to edit.
New Message	The updated text content that will replace the original message text.

Output

The node outputs a JSON object representing the response from the Green API after attempting to edit the message. This typically includes confirmation of the edit operation and any relevant metadata returned by the API.

No binary data output is involved in this operation.

Example output JSON structure (simplified):

{
  "idMessage": "BAE5367237E13A87",
  "status": "edited",
  "chatId": "972501234567@c.us",
  "message": "Updated message text"
}

Dependencies

Requires an active Green API account with valid credentials: an instance ID and an API token.
The node makes HTTP POST requests to the Green API endpoints.
Proper configuration of these credentials in n8n is necessary for authentication.
No additional external dependencies are required.

Troubleshooting

Error: Failed to edit message
This error occurs if the API request to edit the message fails. Common causes include:
- Invalid or expired API credentials.
- Incorrect message ID (the message may not exist or belong to the authenticated instance).
- Network connectivity issues.
Resolution:
- Verify that the API credentials are correctly set and active.
- Confirm the message ID is correct and corresponds to a message sent from the authenticated instance.
- Check network connectivity and retry.
Node configured as trigger but used as action
If the node's mode is set to "trigger," it cannot perform actions like editing messages. Ensure the mode is set to "action" when using this operation.
