You can issue cards and simulate purchases using your own Stripe integration in test mode. This allows you to test your integration before you go live without having to make real purchases. You can only use these cards for testing within your Stripe account and not for external purchases.
When testing your authorization endpoint, make sure that you have set the endpoint for test mode in your Issuing settings. Toggle View test data to switch between test and live mode data and settings.
Funding your test mode Issuing balance
Before creating test mode transactions, you must add test mode funds to the Issuing balance on your account. These aren’t real funds, and you can only use them for simulating purchases in test mode.
Issuing users in the US
Issuing users in the US use “pull” funding, and use Top-ups to fund their Issuing balance. You can create test mode top-ups in the Dashboard, or with the Top-ups API. Read more about funding Issuing balances for US users.
Issuing users in the UK and euro area
To top up their balance, Issuing users in the UK and Europe “push” funds using Funding Instructions. You can do this in the test mode Dashboard, or with the Funding Instructions API. Read more about funding Issuing balances for UK and euro area users.
