A client of mine is selling tickets for a fund raiser and they'd like to ask for the minimum donation amount and allow people to enter more, if they wish. I read the specs for the donate button however, I did not see information regarding setting a minimum donation amount. Is there a key/value pair that would do this?
Welcome to the Boards!
If you would like to add additional variables to the donation button code you can visit PayPal's Developer Forum here. They may be able to help you a little better. I wish you luck.
