Coinify's Payment API provides multiple options for testing. It enables you to speed up your testing process by setting payment intents in a desired state instantly using the test API endpoints or directly via the Payment Window UI without having to wait for network confirmations or send testnet bitcoin to test different Payment Intent states. On the other hand, you can also test Payment Intent flows using bitcoin testnet network transactions.
