Gracfer for a Backend

If any of those custom types fail, i it is for the library that i use. It never hits my application. So you can automatically remove type of bad creditcard imput from users before it even hits yourapi. Which i think is one of the best parts about using gracfer for a back end. But would i like, i cand of want to go back to making the server for people. Ogt her, if you ave to ever make the server, think grap cule is really great to be.
