In the sandbox environment, you can deterministically trigger payment failures by setting the payment amount to one of the values below.
Each amount drives the simulated response and produces the corresponding failure on the payment. The resulting error codes are the same ones documented on the Error Handling page.
Simulation is only active in the sandbox. In production these amounts are treated as ordinary payment values.
