Experiencing Sandbox Connection Issues? TLS 1.2 Is Now Required

[ Edited ]

Authorize.Net now requires a TLS 1.2 connection to our developer sandbox and will require the same for production on Sept 18, 2017.


Please check the code for your solutions and systems to confirm that they can default to TLS 1.2 for your API connections.


You can also review our API Best Practices for details about TLS 1.2 platform support, cipher recommendations, and other integration suggestions.




Webhooks are now available for Authorize.Net

Using SOAP, see our deprecation notice.
Check out Accept.js, our Javascript replacement for DPM.
Pro Tip: Never use test mode in the sandbox, instead use the Testing Guide.
