Stack Overflow is the best place to ask questions for GCP.
The documentation does describe how to authenticate to this API. If I
recall correctly, API keys are not supported.

I'm trying to make an api call to google vision api using an api key from
golang. But I'm getting a 400: bad request, invalid_grant error.
What is the right way to make this call?
import (
// ...
"google.golang.org/api/option"
vision "cloud.google.com/go/vision/apiv1"
"golang.org/x/net/context"
)
func getImageLabels(filename string) []string {
ctx := context.Background()
apiKey := "..." // my api key has been generated in the console and should
be fine.
apiKeyOption := option.WithAPIKey(apiKey)
client, err := vision.NewImageAnnotatorClient(ctx, apiKeyOption)
// ...
labels, err := client.DetectLabels(ctx, image, nil, 10)
}
*Failed to detect labels: rpc error: code = Internal desc = transport:
oauth2: cannot fetch token: 400 Bad Request*
*Response: {*
* "error" : "invalid_grant"*
*}*
p.s. is there a specific group for gcp+golang that I should preferably post
this to?
