In google adwords, ClienLogin method is deprecated. I need to switch over to Oauth2 authentication method
My example code is below,
:method: OAUTH2_JWT
:user_agent: test
:developer_token: "*********"
:oauth2_issuer: "*********#developer.gserviceaccount.com"
:oauth2_secret: notasecret
:oauth2_keyfile: '*********-privatekey.p12'
:client_id: *********.googleusercontent.com
:oauth2_prn: *********#developer.gserviceaccount.com
:client_customer_id: *********
When i running the request , i am getting error as below
Authorization failed. Server message: (Signet::AuthorizationError)
{
"error" : "access_denied",
"error_description" : "Requested scopes not allowed: https://adwords.google.com/api/adwords/"
}
Anyone tell me solution to fetch the access token.
An OAuth2 + Google service account means that you have a Google Apps domain (e.g. you use GMail enterprise).
I recommend you to watch the Adwords API workshop on OAuth2
The OAuth2 playground is also helpful for testing purposes, before you try to use it straight from your app.

I am trying to get new access token from my refresh token for google drive api. In my google playground it works but when I want to create the same request in postman or my code it doesn't work and I always get error "Invalid grand type". I don't know to find what is problem.

You need to understand that there is three steps to the Oauth2 dance.
step one is requesting access of the user and getting the authorization code.
HTTP GET https://accounts.google.com/o/oauth2/auth?client_id={clientid}.apps.googleusercontent.com&redirect_uri=urn:ietf:wg:oauth:2.0:oob&scope=https://www.googleapis.com/auth/analytics.readonly&response_type=code
Note &response_type=code tells the server you want an authorization code returned.
step two is to exchange that code for an access token and refresh token.
POST https://accounts.google.com/o/oauth2/token
code=4/X9lG6uWd8-MMJPElWggHZRzyFKtp.QubAT_P-GEwePvB8fYmgkJzntDnaiAI&client_id={ClientId}.apps.googleusercontent.com&client_secret={ClientSecret}&redirect_uri=urn:ietf:wg:oauth:2.0:oob&grant_type=authorization_code
Note the part where it says &grant_type=authorization_code. this tells the server you are giving them an authorization code.
3 the final step is refreshing your access token.
POST https://accounts.google.com/o/oauth2/token
client_id={ClientId}.apps.googleusercontent.com&client_secret={ClientSecret}&refresh_token=1/ffYmfI0sjR54Ft9oupubLzrJhD1hZS5tWQcyAvNECCA&grant_type=refresh_token
Note &grant_type=refresh_token you are telling the server you are sending them a refresh token.
You appear to be sending a refresh token with the wrong grant type.
I have a video on how to set up postman to use google oauth2
How to set up Oauth2 in PostMan.
Google 3 Legged OAuth2 Flow
Note: Due to a recent change with Making Google OAuth interactions safer by using more secure OAuth flows redirect uri of urn:ietf:wg:oauth:2.0:oob is going to stop working soon.
So I'm trying to use the Home Graph API by calling the API endpoint
https://homegraph.googleapis.com/v1/devices:requestSync
It is a HTTP POST request and it needs an ACCESS_TOKEN and service account key.
Getting the service account key is easily done as per Google's documentation. The issue is getting the ACCESS_TOKEN.
As per this documentation by Google, I need to get ACCESS_TOKEN created using the following scope of permissions
https://www.googleapis.com/auth/homegraph
I opened OAuth 2.0 Playground to request a developer temporary ACCESS_TOKEN for testing. I wrote all the necessary urls and in scope I wrote this-
scope is written to be authorized
Now after this, I am navigated to my Authorization URL (ie, Google's sign in page). I login with email id and password.
If credentials are correct and scope mentioned is valid then I should have been redirected to OAuth playground page with authorization code which I would have exchanged for access token and refresh token.
But, what actually happens is after I enter my credentials, I get following error and I am never redirected to Oauth Playground page-
Authorization Error
Error 400: invalid_scope
Some requested scopes cannot be shown: [https://www.googleapis.com/auth/homegraph]
Request Details
access_type=offline
o2v=2
response_type=code
redirect_uri=https://developers.google.com/oauthplayground
prompt=consent
client_id=xxxxxxxxx.apps.googleusercontent.com
scope=https://www.googleapis.com/auth/homegraph**
I searched a lot online too, but couldn't find the actual reason.
So due to this issue with scope, I am not able to get ACCESS_TOKEN.
I have followed Google's documentation and the scope was mentioned there.
This is the pic from oauth 2.0 playground settings- OAuth 2.0 configuration
The issue is that you, a user, should not be getting and sending an access token. The service account should be getting and sending an access token. This is to make sure your service is authorized to talk to the Home Graph API.
You indicated you logged into the OAuth playground with "userid and password". But service accounts don't have passwords.
If you are using one of Google's libraries, it will take care of getting the access token for you, and this is the easiest way to do so. If you are just testing and need an access token, you can use something like oauth2l to get the access token based on the service account credentials.
I had implemented the REST approach to call HomeGraph Report State as below.
We need to follow the below steps:
Create a service account for your project and safely store the json file
Using the service account JSON, get the access token from Google
Using Oauth 2.0 token as Bearer authorization, invoke Report State API
Step 1:
This is straightforward. Please follow the steps in the below link
https://developers.google.com/assistant/smarthome/develop/report-state#expandable-1
Step 2:
Refer below code to get the Access token using service account json
GoogleCredentials credentials = GoogleCredentials
.fromStream(Helper.class.getClassLoader().getResourceAsStream("smart-home-key.json"))
.createScoped("https://www.googleapis.com/auth/homegraph");
credentials.refreshIfExpired();
AccessToken token = credentials.getAccessToken();
return token.getTokenValue();
Step 3:
Invoke Report State API
curl -X POST -H "Authorization: Bearer [[Access token from Step 2]]"
-H "Content-Type: application/json"
-d #request-body.json
"https://homegraph.googleapis.com/v1/devices:reportStateAndNotification"

I need to create request for getting data from Google Analytics API in Postman. I managed to generate access token with playground platform but I need permanent refresh token (in playground I can generate only 24h token).
I tried to generate token in Console API:
I've created project
Add analytics API in my project
Generate client ID and secret code
But I don't know which redirect URL using. Default value that was generate in JSON is urn:ietf:wg:oauth:2.0:oob","http://localhost
Than I've generated authorization code with request (from browser):
https://accounts.google.com/o/oauth2/auth?scope=https://www.googleapis.com/auth/analytics&redirect_uri=http://localhost&response_type=code&client_id=XXXX
And when I tried to generate access_token with POST request in Postman, sending such keys:
code:XXXXXX
redirect_uri:urn:ietf:wg:oauth:2.0:oob (also tryed http://localhost)
client_id:YYYYY
client_secret:ZZZZZZ
scope:https://www.googleapis.com/auth/analytics
grant_type:authorization_code
And got error
{
"error": "invalid_grant",
"error_description": "Bad Request"
}
How should I set grant for Postman? Could you help me to resolve issue and understand what I do wrong
I managed to resolve my issue. It should be added redirect_url https://www.getpostman.com/oauth2/callback
Steps I have followed:
Create a project in Google API console and also enabled Google+
API.
Fetch client API and client secret.
Uncomment code and replace the appropriate value in the code:
Fetch Authorization token using Angular6 after sign in to Google.
While Calling API from postman getting the following error:
"Message": "Authorization has been denied for this request.
I'm working on a intranet-based application and I want to use Google services. Currently I have successfully implemented Google Authentication with "Sign-In for Websites" using JavaScript client-side authentication. My users can now sign in or sign up with their Google accounts.
Now I want to use Google API to create and share Google Sheets with my users. These documents will be created with a specific Google account and then shared with my users.
This is why I want to use this server-slide flow to get a one-time authorization code and exchange it for a refresh token:
https://developers.google.com/identity/sign-in/web/server-side-flow
This refresh token will be stored in my database allowing me to user Google services on behalf of this offline user.
Using JavaScript library, I was able to get the one-time authorization code that I send to my server with a AJAX request.
auth2.grantOfflineAccess({'redirect_uri': 'postmessage'}).then(grantOfflineAccessCallback);
var grantOfflineAccessCallback = function(authResult) {
var auth_code = authResult.code;
// Exchange the one-time authorization code for tokens
$.post(...);
}
On server-side I use Google API PHP Client (v2.0.0-RC6) to acquire an access and refresh token.
$this->client = new Google_Client();
$this->client->setClientId($this->clientId);
$this->client->setClientSecret($this->clientSecret);
$this->client->setAccessType('offline');
$this->client->setApprovalPrompt('force');
$response = $this->client->fetchAccessTokenWithAuthCode($oneTimeCode);
I wasn't able to exchange the authorization code.
Client error: `POST https://www.googleapis.com/oauth2/v4/token` resulted in a `400 Bad Request` response:
{
"error": "invalid_request",
"error_description": "Missing parameter: redirect_uri"
}
On this page we can read:
On the server, exchange the auth code for access and refresh tokens.
Use the access token to call Google APIs on behalf of the user.
On the JAVA example code:
REDIRECT_URI: // Specify the same redirect URI that you use with your web
// app. If you don't have a web version of your app, you can
// specify an empty string.
Because the application I working on is an intranet application, I tried to specify an empty string for this redirect_uri parameter before calling fetchAccessTokenWithAuthCode() method:
$this->client->setRedirectUri('');
... result in Redirect URI must be absolute.
Can we use this hybrid server-slide flow without callback URL?
Is there any solution to my problem?
Thanks,
Edit:
redirect_uri is where the user will be redirected to after he signed in. This URL must be registered in the Google Project (developers console). So redirect_uri is NOT the callback...!
Problem is now solved with:
$this->client->setRedirectUri('http://same.url.as.in.developers.console/');
