Evolution API

Overview

The node "Evolution API" provides an interface to interact with the Evolution API, specifically supporting operations on various resources. For the Group resource and the Fetch Invite Link operation, this node fetches the invite code (invite link) for a specified group within an instance. This is useful when you want to programmatically retrieve the invitation link to share or manage group memberships without manually accessing the platform.

Practical examples include:

• Automating the retrieval of group invite links to distribute them via other communication channels.
• Integrating group invite management into workflows that handle user onboarding or community management.

Properties

Output

The node outputs a JSON array containing the result of the invite link fetch operation. Each item in the array corresponds to the fetched invite code data for the specified group. The exact structure depends on the API response but typically includes fields such as the invite link/code and related metadata.

No binary data output is indicated.

Dependencies

• Requires an API key credential for authenticating with the Evolution API.
• The base URL for requests is set to https://doc.evolution-api.com/api-reference.
• Proper configuration of the API credential in n8n is necessary for successful execution.

Troubleshooting

• Operation not supported error: If the node throws an error stating the operation is not supported, verify that the resource and operation names are correctly set to "groups-api" and "fetch-invite-code" respectively.
• Missing or invalid credentials: Ensure the API key credential is configured and valid.
• Invalid Group ID or Instance Name: Double-check that the provided group ID and instance name exist and are correct; otherwise, the API may return errors or empty results.
• Network or API errors: Check network connectivity and API availability if requests fail.
