Use known customer payments methods during bind

We've recently begun rolling out support so that API integrations may submit known credit card information for policy payment, without the use of Braintree's client libraries.

As these integrations require handling customer payment information directly, we require PCI compliance screening before access to direct payments is granted.

You may read more about the required pieces and information flow in our new Submitting Known Payment Information guide, as well as by reviewing our updated BindPolicy documentation.
