# Mongodb – How to add –sslAllowInvalidCertificates on mongodb uri

mongodbmongodb-3.4

I have a mongodb server requires x.509 certificate. So I have to use --sslPEMKeyFile and --sslCAFile on mongo shell command to connect to that server. It works fine. In my dev environment, I am using --sslAllowInvalidCertificates parameter. It works fine. But I wonder how I can use --sslAllowInvalidCertificates through nodejs driver. I have checked this link http://mongodb.github.io/node-mongodb-native/2.2/reference/connecting/connection-settings/ but it doesn't have the option for invalid certificates.
