Overview

This node triggers workflows based on events from the Evolution API, which is used for WhatsApp-related event handling. It listens for specified events from a configured Evolution API instance and starts the workflow when those events occur. Common use cases include automating responses or processing data when messages are received, chats are updated, or other WhatsApp-related events happen.

Use Case Examples

1. Automatically process incoming WhatsApp messages when a 'Message Received' event occurs.
2. Trigger workflows on chat updates or contact changes to synchronize data with other systems.
3. React to instance status changes or connection updates for monitoring and alerting.

Troubleshooting

• If the webhook registration fails, check the API key and server URL credentials for correctness.
• Ensure the instance name matches the one configured in the Evolution API to receive events properly.
• If no events trigger the workflow, verify that the selected events in the node settings match the events sent by the Evolution API.
• Errors during webhook creation or deletion usually indicate network or permission issues with the Evolution API server.
