Fortumo provides several tools for testing integration and payments before going live with any service. Methods for testing integration differ based on billing solution that has been integrated.
Before going live, all new payment services run in sandbox environment. In sandbox environment no live billing is performed. Once you have finished testing, click the "Go live" button in service information tab to start processing real transactions.
When integrating Cross-Platform Payments, different payment initialization parameters can be used. For testing different payment initialization parameter combinations, Fortumo provides a web payment integration tool.
PSMS Simulation API allows you to trigger notifications to your back-end. With PSMS Simulation API you can specify various different payment parameters that could be important when processing the payment result.
