Overview
This node integrates with the unofficial uazapiGO API to manage WhatsApp instances and send messages. Specifically, for the "Instancia" resource and the "Conectar instância ao WhatsApp" operation, it initiates the connection process of a WhatsApp instance either by generating a QR code or by pairing using a phone number.
Common scenarios where this node is useful include automating the setup and management of WhatsApp sessions in workflows, enabling programmatic control over WhatsApp connections without manual intervention. For example, you can automatically connect a new WhatsApp instance during onboarding or reconnect an instance after disconnection.
Properties
| Name | Meaning |
|---|---|
| Url | Base URL of the uazapiGO API (default: https://api.uazapigo.com). |
| Token da Instância | Authentication token specific to the WhatsApp instance; used to authorize API requests for that instance. |
| Gerar QR Code | Boolean flag indicating whether to generate a QR code (true) for connection or use phone number (false) for pairing. |
| Número de Telefone | Phone number in international format used for pairing when "Gerar QR Code" is set to false. |
Output
The node outputs JSON data representing the response from the uazapiGO API for the connection request. This typically includes information about the connection status, such as QR code data if generated, or confirmation of pairing via phone number.
No binary data output is produced by this operation.
Dependencies
- Requires access to the uazapiGO API endpoint specified by the "Url" property.
- Requires a valid authentication token ("Token da Instância") for the specific WhatsApp instance.
- No special n8n credentials are mandatory but can be configured optionally for admin operations.
Troubleshooting
- Missing or invalid token: The node requires a valid instance token to authenticate requests. If missing or incorrect, the API will reject the connection attempt.
- Incorrect URL: Ensure the base URL is correct and accessible; otherwise, HTTP requests will fail.
- Phone number format: When pairing via phone number, ensure the number is in the correct international format; otherwise, pairing may fail.
- API errors: Any error returned by the API will be included in the node's output if "Continue On Fail" is enabled; otherwise, execution stops with an error.
