NET, PHP, Ruby, Python and Node.js, may also be affected.As previously communicated in the Microsoft 365 Admin Center (for example, communication MC240160 in February 2021), we're moving all online services to Transport Layer Security (TLS) 1.2+. We expect significant impact to Java environments, including Android. TLS 1.2 (SHA-256) - An SSL connection error will be thrown by your code.įor additional help, we have put together language-specific testing notes for common environments.HTTP/1.1 - will return an HTTP 400 response with the following text in the body: "ERROR!

Use our testing environment to verify that your servers support the latest security standards.
The Production endpoints will only allow TLS 1.2 and HTTP/1.1 connections: The Payflow testing endpoints will only allow TLS 1.2 and HTTP/1.1 connections:
These endpoints only allow TLS 1.2 and HTTP/1.1 connections: You can use these endpoints to verify that your code supports the required standards prior to the Production endpoints getting updated. The PayPal Sandbox endpoints have been configured with the latest security standards to which the Production endpoints will be moving.
