Overview

This node interacts with the WSAPI WhatsApp API to retrieve information about a WhatsApp group invite. Specifically, the "Get Invite Info" operation under the "Group" resource allows users to input a WhatsApp group invite code and fetch details related to that invite.

Common scenarios where this node is beneficial include:

  • Validating or previewing WhatsApp group invites before joining or sharing.
  • Automating workflows that require fetching metadata about WhatsApp groups via their invite codes.
  • Integrating WhatsApp group invite information into CRM or communication platforms.

For example, a user can extract the invite code from a WhatsApp group link (the part after https://chat.whatsapp.com/), provide it as input, and get back details such as group name, description, or member count.

Properties

Name Meaning
Invite Code The WhatsApp group invite code to get information about. Extract this code from the invite link URL (the part after https://chat.whatsapp.com/). Example: AbCdEfGhIjKlMnOpQrStUvWxYz.

Output

The node outputs JSON data containing information about the WhatsApp group associated with the provided invite code. This typically includes metadata such as group name, description, participants, and other relevant invite details returned by the WSAPI WhatsApp API.

If the operation returns binary data (not indicated here), it would represent media or files related to the group invite, but for this operation, the output is expected to be purely JSON.

Dependencies

  • Requires an active connection to the WSAPI WhatsApp API service.
  • Needs an API key credential configured in n8n to authenticate requests to the WSAPI endpoint.
  • The base URL for the WSAPI must be set in the credentials configuration.

Troubleshooting

  • Invalid Invite Code: If the invite code is incorrect or expired, the API may return an error or empty response. Verify the invite code extracted from the WhatsApp invite link.
  • Authentication Errors: Ensure the API key credential is correctly configured and has necessary permissions.
  • Network Issues: Connectivity problems to the WSAPI endpoint will cause failures; check network access and base URL correctness.
  • Operation Not Implemented: If the node throws an error about the operation not being implemented, verify that the node version supports the "Get Invite Info" operation for groups.
