Overview

This node interacts with the WaAPI API to check if a specific contact is a registered user. It is useful in scenarios where you need to verify the registration status of contacts within messaging or communication platforms that integrate with WaAPI. For example, before sending messages or performing actions on contacts, you can confirm whether they are registered users to avoid errors or unnecessary operations.

Dependencies

  • Requires an API key credential for authenticating with the WaAPI API.
  • The node sends requests to https://waapi.app/api/v1.
  • Proper configuration of the API key credential in n8n is necessary for successful operation.

Troubleshooting

  • Common issues:

    • Invalid or missing API key credential will cause authentication failures.
    • Incorrectly formatted Contact Id may result in errors or false negatives.
    • Network connectivity problems can prevent reaching the WaAPI endpoint.

  • Error messages:

    • Authentication errors usually indicate invalid or missing credentials; ensure the API key is correctly set up.
