To authenticate with Evolution API using basic auth in n8n, you can use the **HTTP Request node**. Here’s how:
1. Add an HTTP Request node
2. Set the Authentication dropdown to “Basic Auth”
3. Enter your Evolution API username and password in the respective fields
4. Configure the rest of the request (URL, method, etc.)
If Evolution uses header-based authentication instead, select “Header Auth” and add the appropriate header name/value pair containing your credentials.
Make sure your Evolution API endpoint is accessible from your n8n instance. If you’re still having issues, check Evolution’s API documentation for specific authentication requirements.
