Unstoppable Domains Partner API v2 (Legacy) has several integration pathways available for developers. This page reviews the integration guides and overall features for each installation option. For more information about the endpoints, please consult the Partner API v2 (Legacy) endpoint specification.


Partner API Integrations will only work on Polygon L2 network.

Step 1: Locate Your Reseller ID

After setting up access to the Partner API v2 (Legacy), you must obtain your resellerID from the API Panel of the Partner Dashboard to integrate our services into your application for your customers.

Step 2: Add Domain Search Functionality

Before you integrate free or paid domain minting (via Stripe or Redirect URLs) payment flows, you must implement a domain search functionality into your application. Unstoppable Domains provides a set of endpoints to provide domain suggestions, check the availability of domain names, and reserve free domain names.
