Network Tokens Testing

Basis Theory provides a Network Tokens sandbox environment that provides stubbed responses without forwarding your requests to the card networks.

Once the feature is enabled, test tenants will be configured to use the Network Tokens sandbox, and you can use the test cards defined below to simulate various scenarios.

Test Cards​

The following test cards can be used to test different error and success scenarios when creating network tokens.
