If customer want money back from clickbank, how to delete customers file on my server

Hi,

I sell a software where users pay for a Login to this software. This login is saved like this:
Database/CustomerLogins/User1Login.txt

Now if this customer doesn´t want this software and want his/hers money back, in this case from Clickbank.

How will it be possible to automatically delete the file User1Login.txt ?

 

Yes possible. Clickbank API sends refund variables. We use this data in our affiliate program.

You can get programmer to code- receive refund IPN from clickbank then remove user from list.

But you will need a coder

 

That sounds wonderful. I am a fully C# and ASP.net programmer myself, so I will be able to do this.

The only thing I need to know is where I can find documentation and examples of this kind of functionality.
How and where this API send refund variables and how I can retreive them and so on...

Like if a customer refund this product, how can I match this against the purchase and so on?

I found information here but not examples:
http://www.clickbank.com/help/account-help/account-tools/clickbank-api/

One information was the one I am after to retreive but are looking for reallife coding examples
Request a refund for a customer’s purchase

 

I managed to find the function for this. I have put an API and CLERK key in my Account tab. I have put them in this function. (I have changed the keys in this example so they are not the right one)

It do retreive this information for a buy. What I wonder is how a refund tag would look like. I beleive that tag should be avaliable for this order if that did occur?
