Primer Sandbox Processor

Primer provides a Sandbox Processor that can be used in the Sandbox environment to make test payments and validate your integration. This processor comes with:

a set of test card numbers to trigger various scenarios
a set of mocked payment methods to create your first payments on the checkout

Keep in mind:

For PCI-compliance reasons, only test card numbers are allowed in Sandbox. A payment will fail if a non-test card number is used.
No error will be raised in production for using a test card number
