How to Integrate Payment Gateway in Asp.net

Authorized.net Integrate Payment Gateway within Asp.net MVC – Accept Hosted

Accept Hosted:

Accept Hosted is a mobile-optimized payment form hosted by Authorize.Net. It enables you to use the Authorize.Net API to submit payment transactions while maintaining SAQ-A level PCI compliance. You can redirect customers to the Accept Hosted payment form or embed the payment form directly in your own page.

Overview:

How to Integrate Payment Gateway in Asp.net

There are three step of process: How to integrate payment gateway in asp.net c#

  1. Requesting the form token.
  2. Embed the payment form or redirect the customer to the payment form by sending an HTML POST containing the form token.
  3. Your customer completes and submits the payment form. The API sends the transaction to Authorize.Net for processing. The customer is returned to your site, which displays a result page based on the URL followed or the response details sent.

Now we will see the whole process with the example including the code:

Requesting the Form token:

The Accept Hosted process starts with a getHostedPaymentPageRequest API call. The response contains a form token that you can use in a subsequent request to display the hosted payment form.

Note that Form token is Valid for 15 minutes only.

This API call contains two primary element :

  1. Transaction Request: it contains transaction information.
  2. HostedPaymentSettings: It contains the settings that control the Payment form for the transaction.
TRANSACTION REQUEST DETAIL

The transactionRequest element contains transaction details and values that can be used to populate the form fields. It uses the same child elements as the transactionRequest element in createTransactionRequest. Only the transactionType and amount elements are required.

Example:    var transactionRequest = new transactionRequestType

  1. {
  2. transactionType = transactionTypeEnum.authCaptureTransaction.ToString(),
  3. amount = objPayment.amount,
  4. };
HOSTED FORM PARAMETER SETTINGS

This is use to control the payment form. There is one element HostedPaymentSettings within the getHostedPaymentPageRequest API call. Below table contains the all the parameters settings. The values for all parameters sent within hostedPaymentSettings are sent as JSON objects, regardless of whether you sent the getHostedPaymentPageRequest API call in JSON or XML format.
