Symptoms
When processing transactions with the Gravity Forms Stripe Add-On you get the PaymentIntent status: is invalid error.
How To Fix It
This can happen when you try to submit the form with an amount less than the minimum required by Stripe.com: Minimum and maximum charge amounts ($0.50 USD).
This is most commonly the issue when testing your form in live mode and trying to process 10 cents. It can also happen if you use a product with a quantity field. If the quantity is left empty and the total is zero dollars you will see this error.
It can also happen if you are not using a Product Field from the Pricing Fields section within your form.
In a lot of cases you might want to allow your users to enter their own amount, in which case you might use a Numbers field. This will result in the PaymentIntent error.
To fix this, you must use a Product field from the Pricing Fields Section. The Product field has a Field Type “User Defined Price” which you can use instead of the Numbers field.

How the heck did you know I tested on live mode with $0.10? You guys are good.
Haha! Thank you!
If the product field is set to single product with a set price what do you think could be causing the error to happen?
Do you have a total field in your form? If so does the total field reflect the product price?
If you’d like to provide a link to your form I can take a look and see if anything stands out.
