Redirect User to Payment Gateway

package main
import (
	"fmt"
	"github.com/pepco-api/golang-rest-sdk"
)

func main() {	
    // Create an object from PasargadAPI struct
    // e.q: pasargadApi := pasargad.PasargadAPI(4412312,123456,"https://pep.co.ir/ipgtest","cert.xml");
    pasargadApi := pasargad.PasargadAPI(YOUR_MERCHANT_CODE, YOUR_TERMINAL_ID, REDIRECT_URL, CERT_FILE_HERE)
    request := pasargad.CreatePaymentRequest{
        Amount:        15000,
        InvoiceNumber: "4029",
        InvoiceDate:   "2021/08/17 16:12:00",
        //Mobile:        "09121231234",   // Optional
        //Email:         "xxxx@xxxx.xxx", // Optional
    }
    response, err := pasargadApi.Redirect(request)
    if err != nil {
        fmt.Println(err)
    } else {
        fmt.Println(response)
    }
}

This method, will return a string like this:

// output:
 https://pep.shaparak.ir/payment.aspx?n=LySl+5tYkxL5qNMBRthW7DWzV8e3ALnTJUqiCS0V/io=
// Redirect User to the generated URL to make payment

Checking and Verifying Transaction

After Payment Process, User is going to be returned to your REDIRECT_URL.

payment gateway is going to answer the payment result with sending below parameters to your redirectURL (as QueryString parameters):

• InvoiceNumber (iN field)
• InvoiceDate (iD field)
• TransactionReferenceID (tref field)

Store this information in a proper data storage and let's check transaction result by sending a check api request to the Bank:

package main
import (
	"fmt"
	"github.com/pepco-api/golang-rest-sdk"
)

func main() {	
    pasargadApi := pasargad.PasargadAPI(4412312,123456,"https://pep.co.ir/ipgtest","cert.xml");
    request := pasargad.CreateCheckTransactionRequest{
        InvoiceNumber:          "4029",
        InvoiceDate:            "2021/08/17 16:12:00",
        TransactionReferenceID: "637648135297288707", // optional
    }
    response, err := pasargadApi.CheckTransaction(request)
    if err != nil {
        fmt.Println(err)
    } else {
        fmt.Println(response)
    }
}

Successful result:

{
    "TraceNumber": 13,
    "ReferenceNumber": 100200300400500,
    "TransactionDate": "2021/08/08 11:58:23",
    "Action": "1003",
    "TransactionReferenceID": "636843820118990203",
    "InvoiceNumber": "4029",
    "InvoiceDate": "2021/08/08 11:54:03",
    "MerchantCode": 100123,
    "TerminalCode": 200123,
    "Amount": 15000,
    "IsSuccess": true,
    "Message": " "
}

Our code will return CheckTransactionResponse struct as response or err in case of any errors.

If you got IsSuccess with true value, so everything is O.K!

Now, for your successful transaction, you should call VerifyPayment() method to keep the money and Bank makes sure the checking process done properly:

package main
import (
	"fmt"
	"github.com/pepco-api/golang-rest-sdk"
)

func main() {	
	pasargadApi := pasargad.PasargadAPI(4412312,123456,"https://pep.co.ir/ipgtest","cert.xml");
	request := pasargad.CreateVerifyPaymentRequest{
		Amount:        15000,
		InvoiceDate:   "2021/08/17 16:12:00",,
		InvoiceNumber: "4029",
	}
	response, err := pasargadApi.VerifyPayment(request)
	if err != nil {
		fmt.Println(err)
	} else {
		fmt.Println(response)
	}
}

...and the successful response looks like this response:

{
 "IsSuccess": true,
 "Message": " ",
 "MaskedCardNumber": "5022-29**-****-2328",
 "HashedCardNumber": "2DDB1E270C598677AE328AA37C2970E3075E1DB....",
 "ShaparakRefNumber": "100200300400500"
}

Our code will return VerifyPaymentResponse struct as response or err in case of any errors.

Payment Refund

If for any reason, you decided to cancel an order in early hours after taking the order (maximum 2 hours later), you can refund the client payment to his/her bank card.

for this, use Refund() method:

package main
import (
	"fmt"
	"github.com/pepco-api/golang-rest-sdk"
)

func main() {
	pasargadApi := pasargad.PasargadAPI(4412312,123456,"https://pep.co.ir/ipgtest","cert.xml");
	request := pasargad.CreateRefundRequest{
		InvoiceDate:   "2021/08/17 16:12:00",
		InvoiceNumber: "4029",
	}
	response, err := pasargadApi.Refund(request)
	if err != nil {
		fmt.Println(err)
	} else {
		fmt.Println(response)
	}
}

Our code will return RefundResponse struct as response or err in case of any errors.
