Can I use my Onboard card to pay on X (Twitter)?

Flex Card — Yes, Flex cards work on X (formerly known as Twitter) with no issues.

Classic Card — You may experience declines. X is powered by Stripe, and Classic cards have lower acceptance rates with some Stripe-powered platforms. If your Classic card is being declined on X, we recommend switching to a Flex card for a smoother experience.

How to create a Flex card: See the Flex Card Creation Guide for details.
