If you have already collected your customer’s information, you can pass this information to
PayPal to prepopulate the first page of a new customer’s sign-up. The fields and parameters
are listed in the following table. You can pass all or none of this data, as necessary. While your
customer’s sign-up page will be prepopulated, it will still be editable.
To pass this information to the PayPal payment pages, post the variable name and the
associated data to PayPal in the HTML in the form of
variable name = value. You will also
need to change your cmd value to _ext-enter and add a new variable, redirect_cmd,
