I have this warning in my Stripe account: PCI compliance. ACTION NEEDED All users who accept cards need to validate PCI compliance annually. Learn more about PCI compliance. Consider upgrading your integration We strongly recommend that you exclusively use Checkout, Stripe Elements, one of our mobile libraries, or a PCI compliant platform in order to minimize your PCI scope. If you upgrade, Stripe can pre-fill your PCI documentation for you. If you prefer to keep your current setup, you'll need to provide documentation in the next step.
