How online payments work#

Learn which payments integration fits your business.
Use UseePay to accept payments for your business online and around the world with scalable payments solutions. This guide helps you understand which UseePay payments products and services best fit your business.
You have to register for a UseePay account and verify your email before you use any of these products or solutions. After you register, you can access the Dashboard to manage and configure your account and business.

Payment objects#

Use the following core API resources to build and manage online payments:
ResourceDefinition
[PaymentIntent]A way to build dynamic payment flows. A PaymentIntent tracks the lifecycle of a customer checkout flow and triggers additional authentication steps when required by regulatory mandates, custom Radar fraud rules, or redirect-based payment methods.
[PaymentMethod]PaymentMethod objects represent your customer’s payment instruments. You can use them with PaymentIntents to collect payments or save them to Customer objects to store instrument details for future payments.
[Refund]Refund objects allow you to refund a previously created charge that isn’t refunded yet. Funds are refunded to the credit or debit card that’s initially charged.
