Complete Uazapi integration - Premium WhatsApp API with advanced messaging and automation

Actions37

Overview

This node integrates with the Uazapi WhatsApp API to manage webhook configurations for a WhatsApp instance. Specifically, the Set Webhook operation allows users to configure a URL where WhatsApp event notifications (such as incoming messages or status updates) will be sent via webhooks.

Typical use cases include:

  • Setting up a webhook URL to receive real-time WhatsApp message events and automate responses.
  • Integrating WhatsApp messaging events into other systems like CRMs, helpdesk software, or custom workflows.
  • Automating business processes triggered by WhatsApp interactions.

For example, a user can set a webhook URL that points to their server or an n8n webhook node to capture incoming WhatsApp messages and trigger further automation such as logging conversations or sending automated replies.

Properties

Name Meaning
Webhook URL The URL endpoint where WhatsApp event notifications will be sent.
Additional Fields Optional extra parameters to customize webhook behavior:
- Reply to Message ID ID of a message to reply to (if applicable).
- Delay (seconds) Delay before sending a message (in seconds).
- Disable Link Preview Whether to disable link previews in messages (true/false).

Output

The node outputs a JSON object containing the response from the Uazapi API after setting the webhook. This typically includes confirmation details about the webhook configuration.

Example output structure:

{
  "status": "success",
  "webhook": "https://your-webhook-url.com",
  "instance": "instance_id",
  "message": "Webhook set successfully"
}

No binary data is produced by this operation.

Dependencies

  • Requires an active Uazapi WhatsApp API account.
  • Needs an API key credential and authentication token configured in n8n credentials for Uazapi.
  • The node sends requests to the Uazapi API endpoint specified in the credentials.
  • Proper network access to the webhook URL must be ensured so that WhatsApp servers can reach it.

Troubleshooting

  • Common issues:

    • Invalid or unreachable webhook URL: Ensure the URL is publicly accessible and uses HTTPS if required.
    • Missing or incorrect API credentials: Verify that the API key and tokens are correctly configured.
    • Network connectivity problems between n8n and Uazapi API or webhook endpoint.

  • Error messages:

    • "Unknown resource: webhook": Occurs if the resource parameter is incorrectly set; ensure "webhook" is selected.
    • API authorization errors: Check that the API token and key are valid and have not expired.
    • HTTP errors from the webhook URL (e.g., 404, 500): Confirm the webhook endpoint is correct and operational.

To resolve errors, verify all input parameters, credentials, and network accessibility.
