PayPal API Subscriptions

This plugin is deprecated and should not be used for new installations.

PayPal API Subscriptions was built in 2008 using the PayPal NVP (Name-Value Pair) API v52.0, which PayPal has since discontinued in favour of their REST APIs. The plugin also directly handles raw credit card numbers on your server, which creates PCI compliance obligations that most WordPress sites cannot meet.

Recommended alternatives:

• WooCommerce + PayPal Payments — modern PayPal integration with Smart Buttons (card data never touches your server)
• MemberPress — full membership/subscription management with PayPal and Stripe
• Paid Memberships Pro — free membership plugin with PayPal support

What happens in v1.2.0:

• Existing [ppsa] shortcodes display a retirement message instead of subscription buttons
• An admin notice reminds you to migrate
• All PayPal API code, the credit card form, and bundled jQuery have been removed
