Zapper does not provide a sandbox API, but rather test accounts that are configured to accept transactions from predefined cards.

Test Merchant

Request a Zapper merchant test account from support@zapper.co.za. You will be provided with the test Merchant ID and Site ID which can be used for API calls and the Javascript Library.

Test Transactions

In order to test your integration, Zapper allows test cards to be used in combination with different amount ranges, that result in different transaction statuses.
