How To Integrate A CMS With A Payment Gateway
IntermediateQuick Answer
TL;DR
Integrate a content management system (CMS) with a payment gateway like Stripe, PayPal, or Square by using the CMS to manage product and service content while the payment gateway's client-side SDK handles secure checkout. The CMS stores product descriptions, pricing display, and purchase page content while the payment gateway handles actual transactions, PCI compliance, and payment processing. Never store credit card data in your CMS — always use the gateway's hosted checkout or tokenized payments.
Key Takeaways
- The CMS manages content (product descriptions, pricing pages); the payment gateway handles transactions
- Use the gateway's client-side SDK or hosted checkout for PCI-compliant payment processing
- Never store credit card numbers, CVVs, or sensitive payment data in your CMS
- Stripe Checkout and PayPal hosted buttons are the simplest integration paths
- Webhooks from the payment gateway confirm successful payments and trigger fulfillment
