1. PHP version (check Module version guide)
2. TLS 1.2 & cURL 1.0.1c

The Payment Card Industry (PCI) Council has mandated that early versions of TLS be retired from service. All organizations that handle credit card information are required to comply with this standard. As part of this obligation, PayPal has upgraded its services to require TLS 1.2 for all HTTPS connections. Connections to the sandbox environment use only TLS 1.2.

For more official, relevant information, see the 2017-2018 Merchant Security Roadmap Microsite:

• TLS 1.2 and HTTP/1.1 Upgrade Microsite
• SSL Certificate Upgrade Microsite

Check the version of your URL’s underlying security library. If you use OpenSSL libraries, please update them to at least version 1.0.1c.

PrestaShop modules are open-source extensions to the PrestaShop e-commerce solution. Everyone is welcome and even encouraged to contribute with their own improvements.

Contributors must follow the following rules:

• Make your Pull Request on the "develop" branch, NOT the "master" branch.
• Do not update the module's version number.
• Follow the coding standards.

Contributors wishing to edit a module's files should follow the following process:

1. Create your GitHub account, if you do not have one already.
2. Fork the paypal project to your GitHub account.
3. Clone your fork to your local machine in the /modules directory of your PrestaShop installation.
4. Create a branch in your local clone of the module for your changes.
5. Change the files in your branch. Be sure to follow the coding standards!
6. Push your changed branch to your fork in your GitHub account.
7. Create a pull request for your changes on the 'develop' branch of the module's project. Be sure to follow the commit message norm in your pull request. If you need help to make a pull request, read the Github help page about creating pull requests.
8. Wait for one of the core developers either to include your change in the codebase, or to comment on possible improvements you should make to your code.

That's it: you have contributed to this open-source project! Congratulations!
