In version 1.2 of indico there is an add-on that allows you to use a payment gateway like PayPal. The plugin in this version is located on the path:
/ MaKaC / plugins / Epayment / myPay
Is there a way to convert that plugin that works for version 1.2 to version 2.2 of indico?
What would be the correct way to create a complement in version 2.2 of Indico?
Do you know any template or documentation to customize the add-on that use payment gateways?
