New requirement for vendor payments with the CARD_ACCOUNT funding account type

When you create a vendor payment with a card account, we now require you to specify the card funding purpose for the payment. Set the card funding purpose as the vendor industry.

In your create payment request with POST /v3/payments, cardFundingPurpose is a new required body parameter for the CARD_ACCOUNT funding account type.

See POST /v3/payments in the API reference for more information.
