We have a transcript request form that automatically calculates how much is owed based on the amount of transcripts requested and if it is standard or rush delivery. We take payments through PayPal and currently just provide a link. We would like to be able to pass the Total Amount value to PayPal so when they have selected Online Payment and click Submit it would redirect them to PayPal and auto fill the amount due and give a description of the product being paid for.
Has anyone done an integration like this with PayPal using Forms or could point me in the right direction?
