Overview
To ensure your integration with Moment APIs functions correctly, you can simulate payment flows during development. This allows you to test various scenarios without any real money movement.Testing Cards
When testing card payments, always use test API keys. Only use the specified test cards listed below. Do not use real card information under any circumstances.Note: The 3DS challenge page will not be displayed during testing, as the flow is being simulated to mimic a frictionless authentication experience.
