Integrate NOWPayments Into an AI-Built Website

Explore how to instruct an AI coding assistant to build a payment integration while keeping credentials private and processing payment statuses correctly.

Understand Payment Verification

Learn why a success-page redirect alone is not sufficient proof of payment, how server-side verification works, and why authentic notifications and correct order matching matter.

Build or Review a Custom Integration

Discover the essential components of a backend payment workflow, including payment creation, webhook notifications, order tracking, and product delivery.

Test Before Launching

Use practical checklists to identify common mistakes involving failed payments, expired transactions, incorrect amounts, duplicate notifications, and insecure credential handling.
