Integration oficial of Wasapi API for n8n

Actions19

Overview

This node integrates with the Wasapi API to perform operations related to WhatsApp contacts. Specifically, the "Contact - Get" operation retrieves information about a WhatsApp contact using their phone number. This is useful in scenarios where you want to fetch details of a user based on their WhatsApp ID, such as verifying if a contact exists, retrieving profile information, or preparing personalized messaging workflows.

Practical examples include:

  • Fetching contact details before sending a message.
  • Validating phone numbers in your CRM against WhatsApp contacts.
  • Enriching contact data with WhatsApp-specific information for marketing automation.

Properties

Name Meaning
Phone Number The WhatsApp phone number of the contact to retrieve. Must include the country code and contain no spaces. For example, use 573102938401 instead of +57 310 293 8401.

Output

The node outputs JSON data representing the WhatsApp contact's details retrieved from the Wasapi API. This typically includes fields such as the contact's name, status, profile picture URL, and other metadata associated with the WhatsApp account.

If the contact is not found or the phone number is invalid, the output will reflect an error or empty result accordingly.

The node does not output binary data.

Dependencies

  • Requires an active Wasapi API key credential configured in n8n.
  • The node makes HTTP requests to the Wasapi API endpoint at https://api-ws.wasapi.io/api/v1.
  • Proper network connectivity to the Wasapi service is necessary.

Troubleshooting

  • Invalid Phone Number Format: Ensure the phone number includes the country code and contains no spaces or special characters. For example, use 573102938401 rather than +57 310 293 8401.
  • Contact Not Found: If the contact does not exist on WhatsApp or is not registered with Wasapi, the node may return an empty response or an error.
  • API Authentication Errors: Verify that the Wasapi API key credential is correctly set up and has not expired.
  • Network Issues: Check internet connectivity and firewall settings that might block access to the Wasapi API endpoint.
