Overview

Link internal (custodial) wallets to your card to use them as funding sources for card transactions. Users can link up to 5 wallets, with priority determining the order in which they are charged during purchases. Use Cases:
  • Enable card payments from specific wallets
  • Manage which currencies fund card transactions
  • Control payment source priority
  • Temporarily disable wallet usage for cards
Retrieve all custodial wallets currently linked to the user’s card.
