SSL Certificate Updates for Legacy SDKs

Beginning April 29, 2018, Authorize.Net began updating its SSL certificates on the and endpoints.  Legacy SDKs may point to these endpoints and therefore require a new cert.pem file located in Authorize.Net’s GitHub repository.  Additionally, if your payment solution pins Authorize.Net’s certificates or related information, please update accordingly. 


We greatly apologize for any inconvenience this may have caused.
