Because we support our merchants in helping them grow their business, we continue to make significant investments and improvements to our infrastructure. These improvements sometimes require us to perform necessary service upgrades.
Please read below as we explain what the change is, and what action may be required by you.*
Over the course of 2015 and 2016, PayPal will be working towards upgrading various SSL certificates. The changes include upgrading the following:
1. The version of the VeriSign Trusted Root Certificate used to establish secure connections to PayPal.
2. The signing algorithm of certificates (from SHA-1 to SHA-256).
Why is this happening?
We’re taking measures to address industry-wide security concerns which aren’t unique to PayPal. When implemented, these measures can help us improve the security and reliability of our PayPal integrations and help guard against current and future security threats.
When is this happening?
We’ve published the schedule of our service upgrade plan. Please check our 2015-2016 SSL Certificate Change microsite ( https://ppmts.custhelp.com/app/answers/detail/a_id/1236 ) for the most recent updates as published schedules may change. Our efforts to upgrade SSL certificates for our production endpoints are scheduled to start in May 2015, and will continue into next year.
Please note – Testing in the Sandbox environment is one of the best ways to make sure your integration works. Sandbox endpoints have been upgraded to accept secure connections signed by the G5 Root Certificate. Please review the microsite for information when SHA-256 testing is available for your integration.
What do I need to do?
For information regarding the important details of these upgrades, how it may impact your integration, and what you must do to future-proof your integration, please refer to the Merchant Security System Upgrade Guide on the microsite.
*Please note – If you’re impacted by this upgrade, you may be required to implement these changes prior to the dates listed on the microsite. Otherwise, you may not be able to process payments through your current integration with PayPal. In addition, if you’re integrated with a third party, please check with them on any additional steps you may need to take.
