I'm getting InvalidArgument always

[Federico Extramiana]

Hello,

I'm trying to integrete with google adds using Go and gprc (using google's generated libraries)

I'm making a request to get a campaign but it always returns InvalidArgument, I'd tried almost anything

I tried to use Rest api (same credentials, same resources) and worked

Does anyone knows whats going on??

the code:

func getClient() *grpc.ClientConn {
   token := oauth2.Token{
      AccessToken:  "MyAccessToken",
      TokenType:    "Bearer",
      RefreshToken: "MyToken",
      Expiry:       time.Now(),
   }

   config := oauth2.Config{
      ClientID:     "MyClientID",

      ClientSecret: "MyClientSecret",

      Endpoint:     google.Endpoint,
      Scopes:       []string{"https://www.googleapis.com/auth/adwords"},
   }

   tokenSource := config.TokenSource(context.Background(), &token)

   t, err := tokenSource.Token()
   if err != nil {
      fmt.Println(err)
      return nil
   }
   perRPC := oauth.NewOauthAccess(t)

   // TSL credentials
   pool, err := x509.SystemCertPool()
   if err != nil {
      fmt.Println(err)
      return nil
   }
   creds := credentials.NewClientTLSFromCert(pool, "")

   // client init
   connection, err := grpc.Dial(
      "googleads.googleapis.com:443",
      grpc.WithPerRPCCredentials(perRPC),
      grpc.WithTransportCredentials(creds),
   )

   if err != nil {
      fmt.Println(err)
      return nil
   }

   return connection
}

func getCampaign() {
   service := googleads.NewCampaignServiceClient(getClient())

   // request
   headers := make(metadata.MD)
   headers["developer-token"] = []string{"my-developer-token"}
   header := grpc.CallOption(grpc.HeaderCallOption{HeaderAddr: &headers})
   request := &googleads.GetCampaignRequest{ResourceName: "customers/1234567890/campaigns/123456789} // I faked the ids

   // call
   response, err := service.GetCampaign(context.Background(), request, header)
   if err != nil {
      fmt.Println(err)
      return
   }

   fmt.Println(response, err)
}

UPDATE: developer token is missing

How I should set it?

Hello,

The developer token should be placed in the same file as where you're credentials are such as client id and secret.

Regards,
