Hi!
I am just started to learn outsystems and now evaluating it.
I am trying to use web services that require crt certificates, that can be downloaded from api service provider. I was told that this can be achieved :
"You can also use client certificates with the Agile Platform to make web service calls - simply add the certificates in Service Center (in CRT format) in Administration -> Certificates, then configure your web-reference to use them to make the call in the eSpace properties."
But in that path there is only 

Server Configuration | Front-end Servers | Zones | Email

and no certificates.
Second way is using oAuth tokens. Hava any one any suggestions how to achieve that in outsystems ?
