Non Official Whatsapp API

Actions10

Overview

This n8n node, "Quepasa (Whatsapp)", provides integration with the unofficial Quepasa WhatsApp API. It allows users to interact with WhatsApp functionalities such as retrieving information, sending messages, managing webhooks, and performing control operations through a unified interface in n8n workflows.

Common scenarios:

  • Automating WhatsApp message sending from business systems.
  • Fetching account or bot information for monitoring.
  • Managing webhooks for real-time event handling.
  • Controlling bot behavior programmatically.

Practical examples:

  • Sending automated order confirmations via WhatsApp.
  • Receiving notifications when a new message is received on WhatsApp.
  • Retrieving bot status or configuration details.

Properties

Name Type Meaning
Authentication options Selects the authentication method: either manual parameters or predefined credentials.
BaseUrl string The base URL of the Quepasa API. Required if using parameter-based authentication.
Token string The token for the WhatsApp bot. Required if using parameter-based authentication.

Output

  • The node outputs a JSON array containing the results of the selected resource and operation.
  • For most operations, each output item will be a JSON object representing the response from the Quepasa API.
  • If the operation is "download", the node may output binary data (e.g., media files), which will be included in the binary property of the output items.

Dependencies

  • External Service: Requires access to the Quepasa WhatsApp API endpoint.
  • API Key/Token: A valid WhatsApp bot token is required.
  • n8n Credentials: Optionally uses n8n credential management for storing API tokens securely.

Troubleshooting

Common issues:

  • Authentication errors: Occur if the BaseUrl or Token is incorrect, or if the credentials are not set up properly.
  • Network errors: If the Quepasa API endpoint is unreachable, requests will fail.
  • Invalid operation/resource: Selecting an unsupported combination of resource and operation may result in errors.

Error messages:

  • "Authentication successful": Indicates successful connection during credential testing.
  • Errors thrown by the node will typically include the message from the Quepasa API or network layer. For example, "Invalid token" or "Resource not found".
  • If continueOnFail is enabled, errors for individual items will be included in the output under an error field in the JSON.

How to resolve:

  • Double-check the BaseUrl and Token values.
  • Ensure the Quepasa API service is running and accessible.
  • Use the credential test feature to verify authentication before running workflows.
