Testing Marketplace

The marketplace's testing capabilities depend on the merchant registration method you choose.

You can test the functionality of the marketplace in a sandbox environment. The test account is available to anyone who is currently testing the service, so submerchants' balances, as well as the marketplace itself, may change without your input.


The marketplace test account is available only to marketplace platforms that register merchants through a web form.

If you want to perform payout from a test account, you should set value of shopId parameter to 0pKb1aqC.
