Business Signup API overview

The Business Signup API has one endpoint that checks if a domain is available. If you want to claim a domain, go to Verify your domain and follow the instructions for your chosen verification method.

To check domain availability, you need:

  • A Trustpilot for Business account with access to the Connect module. If you don’t have an account, go to Request a demo.
  • An access token. If you don’t have an access token, follow the steps in the Authentication overview.

To use the Business Signup API, call the Check domain availability endpoint, include the domain you’re interested in, and add your access token.

Refer to the following example:

curl -X GET "https://api.trustpilot.com/v1/business-signup/domain-availability" \
-G \
--data-urlencode "domain=example" \
-H "Authorization: Bearer YOUR-ACCESS-TOKEN"

The endpoint returns either true or false. True means that the domain is available. False means that a domain is already in use.
