* s2Member's PayPal Checkout (REST) handler. |
| 5 |
* |
| 6 |
* Server-side entrypoint for PayPal Checkout operations used by s2Member shortcodes: |
| 7 |
* - Buy Now: create_order + capture_order (one-time payments). |
| 8 |
* - Subscriptions (membership level): get_plan_id + confirm_subscription. |
| 9 |
* - output="url|anchor": redirect/return flow (does not create orders on page load). |
| 10 |
* - Optional: cancel_subscription (on-site cancel for logged-in users). |
| 11 |
* |
| 12 |
* Successful operations are proxied into s2Member's existing PayPal notify/return handlers, |
| 13 |
* preserving legacy provisioning behavior (level/ccaps/EOT/etc.) without rewriting it. |
