The merchant dashboard gives you an overview of all your wallets, transactions and customers. It also lets you monitor pending settlements in all your currencies and refund transactions in one click. Before production activation, you need to enter your redirect and webhook URLs in this dashboard.


Mona has a sandbox environment to test with where are transactions are dummy. To use the card checkout feature you can use the test card data given to you during onboarding.
