Project modes: Test and Live

Byl provides two project modes — Test and Live — to make it easy to build, test, and then accept real payments.

Test mode

Test mode lets you register a project and start building without paying anything. In this mode:

• You can create a new project and start development right away.
• Test mode works exactly like Live mode, except every transaction is capped at 50₮.
• This lets you exercise the full payment flow and see how revenue is recorded.

Benefits of Test mode

• Experiment without any risk
• Recreate the real payment flow using small-amount transactions
• Catch bugs and issues easily during development

Warning: Transactions made in Test mode are for testing purposes only and are not considered real payments.

Live mode

Live mode connects your project to the real payment systems, allowing you to accept transactions of any amount from your customers.
