NOTE: The PCI Data Security Standard requires that merchants discontinue using early TLS for securing their sites, no later than June 30, 2018. Please contact your solution provider and web hosting company to confirm that your solution and server fully support TLS 1.2. Thank you.

The PCI Security Standards Council recently announced that, as of June 30, 2018, TLS 1.0 (and in some cases, TLS 1.1) will no longer be supported. For details see the PCI SSC document, Migrating from SSL and Early TLS.

As of November 25, 2016, these protocols are enabled:
  • TLS 1.2 (preferred)
  • TLS 1.1
  • TLS 1.0
Authorize.Net does not support any version of Secure Sockets Layer (SSL), as SSL is fully superseded by TLS.

SSL Labs has full reports on the protocol and cipher support of our API endpoints. Please see below for a matrix of reports available, by API endpoint and environment.
