Making requests

API endpoint

It takes up to a minute to activate your account after the registration.

Postman collection

Postman is a desktop and web application that allows you to make requests to an API from a graphical user interface. We recommend using Postman with WhoisXML APIs endpoints when exploring the APIs functionality, as well as when you are troubleshooting issues with your application.

The WhoisXML API Postman collection is available at the following links:

The collection includes a preconfigured environment. You will need to set up the api_key variable to fire each request. Get your personal API KEY on the My products page. If you have questions related to the API, contact us.

The API returns DNS records matching the given search criteria. One request to the API returns DNS records of one type, which shall be specified in the recordType input parameter.

Request body example

    "apiKey": "YOUR_API_KEY",
    "limit": 1000,
    "recordType": "soa",
    "terms": [
            "field": "domain",
            "term": ""

This request returns all SOA records for the "" domain.

You can also use wildcard search. In this case, the term input parameter looks like "google*". Such requests take longer to process, thus try avoiding too wide searches.
