WaAPIInstall

Overview

This node interacts with the WaAPI API to retrieve member requests for a specific group. It is useful in scenarios where you need to manage or monitor pending join requests to WhatsApp groups, such as automating approval workflows, auditing membership requests, or integrating group management into broader communication systems.

For example, you could use this node to fetch all pending member requests of a group and then automatically approve or notify an admin based on custom criteria.

Properties

Output

The node outputs JSON data containing the list of member requests for the specified group chat. This typically includes details about each user who has requested to join the group, such as their identifiers and request status.

No binary data output is produced by this node.

Dependencies

• Requires an active connection to the WaAPI service via an API key credential.
• The node depends on the @devlikeapro/n8n-openapi-node package and the WaAPI OpenAPI specification bundled internally.
• Proper configuration of the API base URL (https://waapi.app/api/v1) and authentication headers is necessary.

Troubleshooting

• Common issues:

  • Invalid or missing instance ID or chat ID will cause the request to fail.
  • Network connectivity problems or incorrect API credentials can lead to authentication errors.
  • If the group chat ID is malformed or does not exist, the API may return an error or empty results.

• Error messages:

  • Authentication errors indicate invalid or missing API keys; verify your credentials.
  • "Not Found" or similar errors suggest the chat ID does not correspond to an existing group.
  • Rate limiting or quota exceeded errors require checking your WaAPI account limits.
