The purchasing endpoint requires an idempotency key to be present in the headers. The client should generate some adequately unique random value for this header, which should be sent along with the purchasing request. The purpose of this header is to prevent accidentally making multiple API calls to purchase the same product due to a connection error. If the request is made multiple times with the same idempotency key, then the API exhibits idempotent behavior, meaning it will return the same response as in the previous call without processing another purchase request. It is therefore safe to call the API multiple times if the response was lost, as long as the same idempotency key is used in the second requestsubsequent requests.

The purchasing API does not restrict the user from purchasing a License for a Product even if they already have a License for the given Product. If different idempotency keys are used for purchasing, then multiple Licenses will be purchased for the user. |
