Authorize.Net is a payment gateway service provider allowing merchants to accept credit cards and electronic check payments through their Web site and over an IP (Internet Protocol) connection.
As payment industry standards evolve, Authorize.Net has seen a need to advise developers on best practices for API usage.
You are may be aware of the new PCI DSS requirements that state all payment systems must disable early TLS by 2018. Users send sensitive information via internet. To encrypt this information,
Transport Layer Security (TLS) technology is used. Earlier Secure Sockets Layer (SSL) was used for this. TLS is the replacement for SSL.
In preparation for this requirement, Authorize.Net plans to disable TLS 1.0 and TLS 1.1 prior to September 18, 2017.
They have disabled the sandbox in advance of production to allow users and developers to test the website or payment solution. The users should ensure that they are no longer using TLS 1.0 or 1.1 prior to September 18th. Users are advised to contact their web developer or payment solution provider, as well as web hosting company, to confirm that they can support TLS 1.2 for users API connections. Users are required to update their web browsers as browsers released prior to 2014 may not support TLS 1.2.
Payment security is the foremost priority for the most website. Please make sure your transactions are secured by making the switch to TLS 1.2.
