Actions37

Overview

This node integrates with the Uazapi WhatsApp API to manage WhatsApp contacts and retrieve contact information. Specifically, the Get Contact Info operation fetches detailed information about a WhatsApp contact based on their phone number.

Common scenarios where this node is beneficial include:

  • Retrieving profile details of a WhatsApp user before sending messages.
  • Verifying contact existence and status in WhatsApp automation workflows.
  • Enriching customer data by fetching up-to-date contact info from WhatsApp.

Practical example:

  • You have a CRM workflow that triggers when a new lead is added. Before sending a WhatsApp message, you use this node to get the contact's WhatsApp profile info to personalize the message or verify the contact is valid.

Properties

Name Meaning
Phone Number The WhatsApp phone number including country code (e.g., 5511999999999) to identify the contact.
Additional Fields Optional extra parameters (none specifically used for this operation).

Output

The output JSON contains the response from the Uazapi API endpoint /v1/contacts/info. This typically includes detailed contact information such as:

  • Contact name
  • WhatsApp ID or number
  • Profile details (if available)
  • Status or presence information

The exact structure depends on the API response but generally provides comprehensive contact metadata.

No binary data output is produced by this operation.

Dependencies

  • Requires an active Uazapi WhatsApp API account with valid credentials:
    • An API key credential for authentication.
    • API token and instance ID configured in the node credentials.
  • The node sends requests to the Uazapi API base URL specified in credentials.
  • Network access to the Uazapi service endpoint is necessary.

Troubleshooting

  • Common issues:

    • Invalid or missing phone number format: Ensure the phone number includes the country code without symbols or spaces.
    • Authentication errors: Verify that the API key, token, and instance ID are correctly set in credentials.
    • API rate limits or service downtime may cause request failures.

  • Error messages:

    • "Unknown resource": Indicates the resource parameter is incorrect; ensure "contact" is selected.
    • HTTP 401 Unauthorized: Check API credentials.
    • HTTP 404 Not Found: The contact number might not exist on WhatsApp or is incorrectly formatted.

  • To resolve errors, confirm all input parameters, credentials, and network connectivity.
