I am currently adding PayPal to an e-commerce site that doesn't take payment straight away so authorizes the payment on checkout then takes it once the product is shipped.
Inbetween that process the order amount can change slightly (within the limits) so when capturing the payment I need to pass an amount, however, I just can't seem to successfully do this, I have followed the API Docs.
I keep getting "422 unprocessable entity" if I do not pass the amount it just takes the full amount as expected.
