ITechPSP payment page SDK

This is a set of libraries in the Go language to ease integration of your service with the ITechPSP Payment Page.

Payment flow

Installation

Simply use go get:

go get github.com/ITechPSP/paymentpage-sdk-go

To update later:

go get -u github.com/ITechPSP/paymentpage-sdk-go

Get URL for payment

import "github.com/ITechPSP/paymentpage-sdk-go"

payment := paymentpage.NewPayment(11, "test_payment_id")
payment.SetParam(paymentpage.ParamPaymentCurrency, "EUR")
payment.SetParam(paymentpage.ParamPaymentAmount, 1000)

gate := paymentpage.NewGate("your project secret")
paymentPageUrl := gate.GetPaymentPageUrl(*payment)

paymentPageUrl here is the signed URL.

Handle callback from ITechPSP

You'll need to autoload this code in order to handle notifications:

import "github.com/ITechPSP/paymentpage-sdk-go"

gate := paymentpage.NewGate("your project secret")
callback, err := gate.HandleCallback(data)

data is the JSON string received from payment system;

err nil or error interface; error returned if signature invalid or callback data can't parse;

callback is the Callback object describing properties received from payment system; callback implements these methods:

1. callback.GetPaymentStatus() Get payment status.
2. callback.GetPayment() Get all payment data.
3. callback.GetPaymentId() Get payment ID in your system.
