Evolution API

Overview

The "Join Group" operation in the Group resource allows an instance to join a specified group using an invite code. This node is useful when automating workflows that require programmatically adding instances or users to groups, such as managing memberships in collaborative platforms or community management systems. For example, you might use this node to automatically enroll new users into a project group after they sign up, by providing the group's invite code.

Properties

Output

The node outputs a JSON array containing the result of the join group operation. The exact structure depends on the API response but typically includes confirmation details such as the instance joined, group information, and status of the join request. There is no indication that binary data is output by this node.

Dependencies

• Requires an API key credential for authenticating with the Evolution API.
• The base URL for API requests is https://doc.evolution-api.com/api-reference.
• Proper configuration of the API authentication credentials within n8n is necessary.

Troubleshooting

• Unsupported operation error: If the node throws an error stating the operation is unsupported, verify that the Resource is set to "Group" and Operation to "Join Group".
• Invalid invite code: Providing an incorrect or expired invite code will likely cause the API to reject the join request. Double-check the invite code value.
• Authentication errors: Ensure the API key credential is correctly configured and has sufficient permissions.
• Network issues: Connectivity problems may prevent the node from reaching the API endpoint; verify network access and proxy settings if applicable.
