Fintoc provides a test mode, or sandbox, for testing the API without making payments or connecting real accounts. The sandbox returns simulated objects without affecting transactions or moving money. Use your test API keys to make requests in test mode. The Dashboard displays these keys with the sk_test_ and pk_test_ prefixes. Each sandbox guide provides credentials for testing its supported user flows. You can use test mode for Movements, Payment Initiation, Direct Debit, and Transfers.

Test mode versus live mode

All Fintoc API requests occur in either test mode or live mode. API objects created in one mode aren’t accessible in the other mode. The following table compares both modes:

Mode	When to use	Objects	How to use
`test` mode	Use `test` mode and its associated API keys as you build your integration.	API calls return simulated objects. For example, you can retrieve and use test `link`, `movement`, `checkout_session`, and `subscription` objects.	Use test bank accounts. You can’t accept real payment methods or work with real accounts.
`live` mode	Use `live` mode and its associated API keys when you’re ready to launch your integration and accept money or connect real accounts.	API calls return real objects. For example, you can retrieve and use real `link`, `movement`, `checkout_session`, and `subscription` objects.	Accept real bank accounts and work with customer accounts. You can accept real payment authorizations and charges, and connect real links.

The Test mode toggle in the Dashboard doesn’t affect your integration code. Your API keys determine whether your integration uses test or live mode.
