Tests in STG Environment.

To test the Subscriptions API in the staging environment, use the parameter plan with the value TEST inside the subscription[] object when calling either the OneShot or PCI endpoints.

This triggers simulated deposits every minute, along with the corresponding webhook events, so you can quickly verify the full subscription lifecycle. The number of deposits generated depends on the value of the plan_unit parameter, making it easy to observe the expected behavior in just a few minutes.
