title: How to allow users to enter custom amount vs charging set amount in stripe?
body: <p>Thus far, I've only seen examples/tutorials for stripe in which you declare an amount via choosen library to charge customers/clients. How would you write code that allows the user to input custom amount for say  a "pay bill" or "donation" form.  Conceptually it seems this might be an if/else statement that sets a high/low parameter but I'm not entirely sure nor how to code this to work with Stripe API. Could really use some help here. Ultimate goal is to make a simple payment page that allows user to make a custom payment and then create a customer object to charge customer at a later date.</p>
