Use Simulations to simulate Billing objects

Test your Billing integration and make sure it behaves as expected. By running a simulation, you can see how various Billing resources like subscriptions change over time. For example, you can see how your setup handles a payment failure for a quarterly renewal.

Simulations use test clocks to control time. In the API and Dashboard, there are references to both. A simulation uses a clock to advance time, and track how things change.

Simulations let you:

• Test complex simulations such as upgrading or changing plans mid-cycle.
• Ensure your integration processes Billing lifecycle webhooks correctly.
• Validate that your app handles trials correctly.
• Build and test multi-phase subscription schedules.
