Topsort API authentication is enforced through the use of a bearer token. Requests must include an authorization header containing a marketplace API key. If such header is missing or invalid, the HTTP response code will be
POST /v1/auctions HTTP/2 Host: sandbox.app.topsort.com ... Authorization: Bearer <YOUR-API-KEY> ...
By this point we will have provided you with credentials to log into Topsort's Auctions Manager. After logging in, open the API Integration page, then click on the Generate API key button.
Server side only
