About this tutorial

This is an end-to-end guide to integrating a CCAvenue payment gateway into ASP.NET web application using official kit. Starting from account setup to successful payment.

Pre-Requirement

  1. Visual Studio
  2. Active CCAvenue account
    1. Merchant ID
    2. Access Code
    3. Working Key

Setting up your CCAvenue account for localhost

In order to run your CCAvenuepayment gateway in localhost, we need to add our localhost into CCAvenue account. You have to write an email to service@ccavenue.com and ask him to add your localhost.  Kindly refer screenshot below for more details.

Example: http://localhost:55181/

Add Reference to the project [Very Important]

Note: Reference DLL file will be available in downloaded integration kit itself.
Browse the downloaded folder
  1. bin → MCPG.ASP.net.ENC.dll & add it to the project.
  2. lib → MCPG.CCA.Util.dll & add it to project.
Note: REMOVE existing dll, if any. You have to add fresh dll.

Add localhost to the project

This step is mandatory to run the CCAvenue setup in local system i.e in a development system. If you didn't ask localhost, this setup won't work because by default asp.net project will point to some default IP like http://127.0.0.1/

So, better add your localhost i.e In my case it is which http://localhost:55181/ is same as in my CCAvenue Account, which we have added in step 1.

Right click project → Properties
