Can I transfer money from my Apple credit card to Apple Cash

Hi, anubis14!

Thanks for stopping by the Apple Support Communities to get help with Apple Cash. We would be happy to provide you with some information regarding adding funds!

According to the following requirements for Apple Cash from Set up Apple Cash - Apple Support, you must use a debit card to transfer funds to and from your Apple Cash card:

"What you need

• Be at least 18 years old and live in the United States.
• Have a compatible device with iOS 11.2 or later or watchOS 4.2 or later. 
• Set up two-factor authentication for your Apple ID. 
• Sign in to iCloud with your Apple ID on any device that you want to use to send or receive money.
• Add an eligible debit card in the Wallet app, so you can send money"

Once you have a debit card added to use with Apple Cash, you can add funds using the steps in Add money to Apple Cash - Apple Support.

Cheers!
