I'm calling an external API from within my App Service. This API is secured with a Thwate certificate which doesn't seem to be installed into the App Service's certificate store by default. Therefore I can't connect to the external API.
How can I add the certificate, one of the Thwate Roots, into my App Service?
The portal only accepts .pfx certificates. I have seen solutions that involve running startup scripts in conjunction with the service definition files, but that feels very hacky. I'm sure there is/should be an easy way to do this. It must be a common requirement.
Update
This isn't a certificate I should need to install for the communication. This is a regular call to an https endpoint. The issue is that Azures doesn't seem to have the correct root/intermediary certificates in the cert store. I need to add the intermediary to the cert store (or the equivalent on the App Service)
