This plugins gives you a great framework to use for integrating with PayPal. 
It stores both live and sandbox API credentials and allows you to switch back 
and forth easily. All NVP API calls are passed through the framework and 
default values such as API version, API credentials, and even currency code are 
added to the request based on settings from the admin panel.
It also has a built in IPN listener that validates messages as coming from 
PayPal then throws WordPress actions based on messages received. For example it 
throws “paypal-recurring_payment_profile_cancel” when someone cancels a 
recurring payment that they had set up with you. It passes along all the info 
that PayPal sent to the action, so it’s simple to create other plugins that use 
this one.
Requires PHP5.

Payment gateways are now requiring commmunication via TLS 1.2. This plugin will test your webserver for compatibility to ensure there is no outage in your ecommerce application.
If your server is not able to communicate via TLS 1.2, you will be shown the appropriate steps to take to upgrade the server version of OpenSSL, PHP, or direct you to update the SSLVERSION of CURL.
The plugin currently offers testing via these API Endpoints: 
* PayPal (https://tlstest.paypal.com/) 
* How’s My SSL? (https://www.howsmyssl.com/a/check)
Testing against these API Endpoints should validate compatibility for other gateways and APIs, even if you are not using PayPal, for example, on your ecommerce application. However, we do plan to add more tests for API Endpoints provided by popular gateways.

TLS 1.2 Compatibility Test

Very simple plugin to ensure your server supports TLS1.2. For example, are you worried about your payment processor being able to work with Stripe? First, make sure this test passes.

This plugin is key to ensuring your eCommerce site can still conduct commerce.

Thanks for making this tool! This saved me a lot of time!

Very helpful!

Verify TLS 1.2 support on your webserver for included API endpoints and diagnose a solution to enable compatibility.
