Quepasa (Whatsapp)

Non Official Whatsapp API

Actions11

Overview

The Quepasa (Whatsapp) node's "Webhook" resource with the "Find" operation is designed to interact with a non-official WhatsApp API, specifically for managing or querying webhooks. This node allows users to search for existing webhook configurations associated with their WhatsApp bot.

Common scenarios:

  • Retrieving a list of all configured webhooks for a WhatsApp bot.
  • Auditing or verifying webhook endpoints currently set up in your Quepasa WhatsApp integration.
  • Automating monitoring or management tasks related to webhook subscriptions.

Practical example:
A user wants to check which URLs are currently registered as webhooks for their WhatsApp bot to ensure messages and events are being delivered to the correct endpoints.

Properties

Display Name Type Meaning
Authentication options Selects how credentials are provided: either by entering parameters manually or using predefined Quepasa credentials.
BaseUrl string The base URL of the Quepasa API. Required if using manual parameter authentication.
Token string The token for the WhatsApp bot. Used to authenticate API requests when not using predefined credentials.

Note:

  • BaseUrl and Token are only required if "Authentication" is set to "Parameters".
  • When "Predefined Quepasa Credentials" is selected, these values are taken from n8n credentials.

Output

The output is a JSON array containing information about the found webhooks. Each item typically includes details such as:

[
  {
    "id": "string",          // Unique identifier of the webhook
    "url": "string",         // Webhook endpoint URL
    "event": "string",       // Event type the webhook listens to
    "status": "string",      // Status of the webhook (e.g., active/inactive)
    // ...other fields depending on API response
  }
]

Note:

  • The exact structure may vary based on the Quepasa API's response.
  • No binary data is produced by this operation.

Dependencies

  • External Service: Requires access to the Quepasa (non-official WhatsApp) API.
  • API Key/Token: A valid WhatsApp bot token is required.
  • n8n Credentials: If using "Predefined Quepasa Credentials", you must configure them in n8n under the appropriate credential type.
  • Environment: Ensure network access to the specified BaseUrl.

Troubleshooting

Common issues:

  • Invalid Token or BaseUrl:
    • Error message: "Authentication failed" or similar.
      Resolution: Double-check the token and BaseUrl. If using predefined credentials, verify they are correctly set up in n8n.
  • Network Errors:
    • Error message: "ENOTFOUND", "ECONNREFUSED", etc.
      Resolution: Ensure the BaseUrl is reachable from your n8n instance.
  • Insufficient Permissions:
    • Error message: "403 Forbidden" or "401 Unauthorized".
      Resolution: Make sure the token has the necessary permissions to access webhook resources.
  • Unexpected API Response:
    • Error message: "Cannot read property 'body' of undefined" or similar.
      Resolution: Check that the Quepasa API is operational and returning expected data.
