go - Google Apps API 403 with Service Account -

-

i've been trying make query against google's admin api list users in google apps organization. have permissions make query in web ui example , results, 403's when try make query service account.

import (     "fmt"     "io/ioutil"     "log"      "golang.org/x/net/context"     "golang.org/x/oauth2/google"     directory "google.golang.org/api/admin/directory_v1" )  func main() {     serviceaccountjson, err := ioutil.readfile(serviceaccountfile)     if err != nil {         log.fatalf("could not read service account credentials file, %s => {%s}", serviceaccountfile, err)     }     config, err := google.jwtconfigfromjson(serviceaccountjson,         directory.admindirectoryuserscope,         directory.admindirectoryuserreadonlyscope,     )      client, err := directory.new(config.client(context.background()))     if err != nil {         log.fatalf("could not create directory service client => {%s}", err)     }      users, err := client.users.list().viewtype(publicdataview).domain(domain).do()     if err != nil {         log.fatalf("failed query users => {%s}", err)     }      _, u := range users.users {         fmt.println(u.name.fullname)     } }

every time execute 403. same query parameters works in try it! section here i'm not sure why fails.

result: failed query users => {googleapi: error 403: not authorized access resource/api, forbidden}

i know question year old, couldnt find anywhere - ive managed fix after running same error you.

basically need set delegation user config, eg:

func main() {     serviceaccountjson, err := ioutil.readfile(serviceaccountfile)     if err != nil {         log.fatalf("could not read service account credentials file, %s => {%s}", serviceaccountfile, err)     }     config, err := google.jwtconfigfromjson(serviceaccountjson,         directory.admindirectoryuserscope,         directory.admindirectoryuserreadonlyscope,     )      // add me     config.subject = "someone@example.com"      client, err := directory.new(config.client(context.background()))     if err != nil {         log.fatalf("could not create directory service client => {%s}", err)     }      users, err := client.users.list().viewtype(publicdataview).domain(domain).do()     if err != nil {         log.fatalf("failed query users => {%s}", err)     }      _, u := range users.users {         fmt.println(u.name.fullname)     } }

see https://github.com/golang/oauth2/blob/master/google/example_test.go#l118

hope helps else!
