Fields Required to Capture an Authorization {#applepay-txn-capture-ex-rest-fields}
==================================================================================

As a best practice, include these REST API fields in your request to capture an authorized Apple Pay payment transaction.  
Depending on your processor, your geographic location, and whether the relaxed address verification system (RAVS) is enabled for your account, some of these fields might not be required. It is your responsibility to determine whether an API field can be omitted from the transaction you are requesting. For information about the relaxed requirements for address data and expiration dates in payment transactions, see the [Payments Developer Guide](https://developer.merchant.services.bankofamerica.com/docs/bofa/en-us/payments/developer/ctv/rest/payments/payments-intro.md "").
