To avoid compare with strings and a more idiomatic way on Golang for errors should be:
Substitute this line:

var (
 ConnectionFailed = "ConnectionFailed"
 UnexpectedResponse = "UnexpectedResponse"
 OK = "OK"
)

for this:

// import "errors"
var (
    ConnectionFailed = errors.New("ConnectionFailed")
    UnexpectedResponse = errors.New("UnexpectedResponse")
)

and just change the method signature for this:

func syntheticHttpRequest(url string, apiToken string) error

and at the end of the function just return nil
