FillFormVars Method

This is used to fill the FormVars property.

Syntax

void __fastcall FillFormVars(String postdata);

Remarks

This method takes the entire post data of the Instant Payment Notification received by the merchant, and uses it to fill the FormVars. You may alternatively parse the post data yourself and fill the FormVars property manually. This method is here for your convenience.

Due to PayPal constantly updating their IPN protocol, there are many form variables that are not automatically parsed by the component. The following is a list of more commonly used form variables which do not have associated properties in this component.
