https://freefrontend.com/jquery-credit-card-plugins/For validation like expiry month/year and the required inputs ought to handle on the UI side so that we can show the Warning/Error message without sending the API call and wait for the responses. - Creating methods to Authenticate Card, Save Card or Charge Card
First set the API Key and Password inside the <AppSetting> element of the WebConfig file and call these before sending the request to the API. On the backend, you will have to write the methods for calling the API for authentication if you need card’s details for authentication purpose only. If you are saving the card you don’t need to call the API for the authentication as it saves the card after authenticating itself.
For the authentication, you can refer to the link https://eway.io/api-v3/?csharp#pre-auth.
For saving the card data you need to call the API for creating the customer and need to pass the card and customer details, it will return the TokenCustomerID as the response and you can save this TokenCustomerID for the future transaction. For more details, you can refer to the link https://eway.io/api-v3/?csharp#token-payments
For charging the card you need to set the Transaction Type as Purchase and you can make the charge by passing the TokenCustomerID or the details of the card. Refer to the link https://eway.io/api-v3/?csharp#direct-connection for more details.Many more APIs are available like Refunds, Transaction Query, Recurring Payments etc., which can also be used. - Error Handling
When any kind of errors occurred during the transaction process the API returns the respective Error Code in the response. eWAY returns the error message if you request using the error code and the preferred language code. You can also show a custom error message by creating a method where you can write your custom error message for the respective error code and call that method inside the error/exception handling code. You can refer to the link https://eway.io/api-v3/#response-amp-error-codes for the various error codes.
To make development even faster and easier, eWAY provides Software Development Kits for . NET (C#). These provide native structures and functions to do the heavy lifting for you. All eWAY SDKs are free, MIT licensed and open source.
