How is the CloudFunctionsService intended to be use used?

Thanks for stopping by to ask us a question! Please make sure to include:

• What you’re trying to do

I am trying to call a private cloud function using a service account credential file

• What code you’ve already tried

            GoogleCredential credential;
            using (var stream = new FileStream("sa.json"), FileMode.Open, FileAccess.Read))
            {
                credential = GoogleCredential.FromStream(stream).CreateScoped();
            }

            var service = new CloudFunctionsService(new BaseClientService.Initializer
            {
                ApplicationName = "testing",
                HttpClientInitializer = credential
            });

• Any error messages you’re getting

I receive no error messages. This cloud function service doesn’t have any public methods to execute a function with credentials. The documentation is not very good and I could use a little help understanding how we are intended to use the cloud function service type.

Thanks in advance.

Why do the docs for CallFunction call out that it should only be used for testing?

That’s a question for the product team, I’m afraid. It’s not something I know the details of. See this page for details of authenticating when calling the function from regular code. You might want to look at the Functions support page for options in terms of asking product questions, such as joining the Slack channel.

I’ll close this issue now as I believe the library-specific aspect of the issue is now covered.

The part I’d like to use the library for is getting the id token from the service account credentials and sending that as the authz header.

You can do that with Google.Apis.Auth without using any Functions-specific library. I haven’t done it for Functions myself, but I’m sure we can sort out an example for you if you get stuck.

The api surface is very limited compared to what is available via cloud functions.

I’m afraid I don’t know what you mean by that.
