Unified payment creation
Create credit card, ATM and convenience-store payment flows through a consistent API shape.
PayCore Developer Center
One payment gateway layer for multiple payment providers.
Use PayCore to create payments, route users to a secure checkout page, receive gateway callbacks, and notify your own system after payment succeeds.
What PayCore standardizes
PayCore keeps payment creation, payment page routing, status query and merchant notification under the same product boundary.
Multi-gateway expansion
Stripe, PLUS, SmilePay and ECPay can live behind the same PayCore gateway layer.
Traceable callbacks
Gateway callbacks and merchant notifications can be recorded, retried and checked by operations staff.
Two ways to create an order
Direct Gateway API
The merchant sends the gateway credentials in each request. This is useful for tests, one-off integrations, or teams that do not want PayCore to store their gateway keys yet.
- Use gateway_credentials
- Specify gateway and method in the URL
- Return a PayCore payment URL or offline payment info
All-in-One Project Checkout
The merchant saves gateway credentials in PayCore, creates a payment project, then uses the PayCore project API key to create payments. The payer chooses a method on the PayCore checkout page.
- Use project_api_key
- Payment methods come from the project settings
- Payer enters PayCore hosted checkout
