What you'll learn

  1. 1

    Checkout, Subscriptions and Webhooks

    Why a "payment successful" page proves nothing, and how webhooks confirm payments, all in test mode.

    Goal: Explain the checkout and webhook flow, and why access must be granted from a verified webhook, not from a success page.

    • The pieces of getting paid
    • Why not trust the success page?
    • A safe webhook handler
    • Project task: test mode only
    • If AI gets stuck

  2. 2

    Can This Provider Pay You?

    Check a payment provider's real requirements for your country and business, compare options honestly, and know your legitimate alternatives.

    Goal: Use official documentation to check whether a payment provider supports your country and business, and compare providers fairly.

    • Availability isn't universal
    • Legitimate or not?
    • What to look for
    • Merchant of record, explained
    • Project task: build a comparison table
    • Before you continue
