All of the parameters that are sent to your IPN script are sent as POST data just like a form POST. &nbsp;<br />
<br />
The only custom value(s) you can send to PayPal in payment requests are within the CUSTOM parameter. &nbsp;Just want to make sure you understand you can't just create your own custom parameters. &nbsp;There's only 1, and it's literally called CUSTOM. &nbsp;It can hold up to 256 characters of text. &nbsp;<br />
<br />
You can pass whatever value you want in the CUSTOM parameter within payment buttons, API requests, etc. &nbsp;Then that same value will come back in the IPN data as POST field with the same name: &nbsp;CUSTOM. &nbsp;<br />
<br />
I'm not familiar with C#, but again, you would handle it just like any other basic form processing you might do.
