# 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](https://help.onboard.xyz/en/article/how-do-i-create-my-onboard-flex-card-w7kh7k/) for details.
