Overview
This node integrates with the UazAPI service, which provides extensive WhatsApp automation capabilities through more than 90 endpoints. Specifically, for the Contact - Get Details operation, the node retrieves detailed information about a WhatsApp contact based on their phone number.
Typical use cases include:
- Fetching up-to-date contact details from your WhatsApp contacts list.
- Automating workflows that require validation or enrichment of contact information before sending messages or performing other actions.
- Integrating WhatsApp contact data into CRM systems or databases.
For example, you might use this node to get the profile name and status of a contact before sending a personalized message.
Properties
| Name | Meaning |
|---|---|
| Contact Phone | The phone number of the contact in international format (e.g., "5511999999999"). This is required to identify which contact's details to retrieve. |
Output
The node outputs a JSON object containing the detailed information of the specified contact as returned by the UazAPI endpoint. The exact structure depends on the API response but typically includes fields such as contact name, phone number, profile picture URL, status message, and other metadata related to the WhatsApp contact.
No binary data output is involved in this operation.
Dependencies
- Requires an active connection to the UazAPI service.
- Requires valid credentials for the UazAPI, including a base URL and authentication tokens configured in n8n.
- The node uses HTTP requests authenticated via these credentials to communicate with the UazAPI endpoints.
Troubleshooting
Common issues:
- Invalid or incorrectly formatted phone numbers may cause the API to return errors or empty results.
- Missing or incorrect API credentials will result in authentication failures.
- Network connectivity problems can prevent successful API calls.
Error messages:
- Authentication errors indicate invalid or missing API keys; verify credential setup.
- "Contact not found" or similar messages suggest the phone number does not exist in the WhatsApp instance's contact list.
- HTTP request failures may indicate server issues or incorrect base URL configuration.
Resolutions:
- Ensure the phone number includes country code without "+" and no spaces.
- Double-check API credentials and base URL in the node's credential settings.
- Confirm network access to the UazAPI service endpoint.
