gopay
A unified payment-processing library for Go with support for Stripe, PayPal, and Razorpay.
The core package (github.com/KARTIKrocks/gopay) defines provider-agnostic
interfaces, types, sentinel errors, a Client, and a MockProvider. Each
provider lives in its own Go module, so importing one never pulls in the
SDKs of the others.
go get github.com/KARTIKrocks/gopay
go get github.com/KARTIKrocks/gopay/stripe # or paypal, razorpay
