Hyperline test mode
Setting up billing often requires experimentation. Use test mode, also called sandbox, to test Hyperline without affecting your production account. When you switch to test mode, Hyperline creates a separate test account. You can create test customers, subscriptions, invoices, usage events, and payments before configuring production billing. Test mode has the same product capabilities as your production account. Use the product documentation to configure your product catalog, manage templates, send invoices, use credits and wallets, and more.Testing payments
Test payment flows before using production bank accounts or payment provider accounts. You can use test card numbers and test bank account numbers as described below.Testing credit card numbers
To test payments in Hyperline, you can use the false credit card numbers provided by Stripe or Mollie (see section below). Payment providers supply test card numbers for payment tests. You can find testing card numbers on the following pages:Testing direct debits
You can test direct debits with test account numbers provided by most payment providers. You can find testing numbers you can use for Stripe on this page.Simulate usage data without code
This applies if you want to configure your first usage-based plan and assign a subscription to a customer in order to test Hyperline. In the test account, you can simulate usage data by generating fake events for a specific customer. This is done in two steps:Go to one of your customers from the Customer section
Then click the Events tab, and click Simulate new events.
Fill in the Event type field with the event name used to aggregate usage in your billing plan configuration.
Fill in:
- The event type (API calls, email sent, document retrieved or created, etc.)
- The date (leave blank if you prefer)
- The number of events to create
- You can optionally add extra parameters to your event with the JSON Payload field.
