I am writing a code in salesforce to update Email signature using the API documentation mentioned in https://developers.google.com/admin-sdk/email-settings/. I am using a 3 legged approach.
Considering that this is an API for domain admins, My questions is
can a user ( non - admin) provide authorization for this API ?.
And can the access token returned as a result of this authorization be used to update his email signature. ?
Right now I am getting an Error 403- "you are not authorized to access this API
Note that this is working fine if a domain admin provide authorization and his access token is used to update his/ any user's email signature
Thanks for your help
With the new updates on the GMAIL Api you can get the user signature by using the method "Users.settings.sendAs: get" explained here https://developers.google.com/gmail/api/v1/reference/users/settings/sendAs/get and it does not require the user to be an admin. This method returns a Users.settings.sendAs resource in the response body and this resource contains the property signature which you can manipulate.
Hope it helps!

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"

We are using Zohocrm api v2 for getting currently logged in user. It works fine for most of the logins.
But we are getting 403 for one of the user account.
URL https://www.zohoapis.com/crm/v2/users?type=CurrentUser
HEADERS {Authorization=Zoho-oauthtoken 1000.786ecda99xxxx}
Response
{"code":"NO_PERMISSION","details":{"permissions":["Crm_Implied_Api_Access"]},"message":"permission
denied","status":"error"}
Response Code 403
Note: From the same zoho team other 2 users were able to login.
Please suggest.
Just adding the steps with which I tried in Postman. It works for me.
If at all any of the steps are different from yours, you could try these steps instead.
Add the client to get client secret
Generate auth token giving client id and secret (and scopes)
After this step, oauth permission request page will be shown, asking user to confirm access to Accounts User Profile and CRM users info. Both have to be accepted.
Use the latest generated token in postman
Execute API GET
My project has the requirement to access the yammer data using the given REST API using server side script(mainly PHP) and not involve a client side login using yammer's OAuth dialog.
I have gone through this document:
https://developer.yammer.com/docs/oauth-2
but this says, we requires user interaction.
What I wanted was can I generate a client_id and client_Secret to further generate access token to make API call out, but in all these processes I only use the authenticated users username and password in my server-side script.
Can anyone suggest a solution or is a client-side interaction required by design?
Thanks in advance!!
You have to have a user authorize the application at least once. This is just the nature of the OAuth implementation and you can't work around it. Having users go through the OAuth flow is considered a best practice.
If you have an OAuth token for a verified admin of Yammer, you can use impersonation to get tokens for end users without them interacting with the OAuth flow.
The below from Microsoft blogs might help you & added source at the end of answer.
Obtain a Verified Admin token for your application in one of the following 2 ways
a. Create the app with a Verified Admin account and then in the app’s Basic Info page, click “Generate a developer token for this application.” Note that you’ll need to use this app’s info in the JS SDK and any subsequent calls.
b. Use the process outlined at https://developer.yammer.com/docs/test-token with a Verified Admin account to get an OAuth token for that VA account. Note that you must use the app info used to generate this token in all future steps.
Obtain the current user’s email address in the server-side script.
Using the VA token obtained in step 1 to authenticate, pass the user’s email address to our Get User by Email Address endpoint documented at https://developer.yammer.com/docs/usersby_emailjsonemailuserdomaincom, and then process the response
a. If the call to the API endpoint returns a 200 OK response, first check the “state” field to make sure the user is “active” and if so, store the “id” field that’s returned and go to step 4
b. If the call returns a 404 or a state other than “active,” direct the user to finish creating and activating their account however you like.
Once you have the user’s ID, you can pass it to our Impersonation endpoint to obtain a pre-authorized OAuth token for that user. This endpoint is documented at https://developer.yammer.com/docs/impersonation and must use the VA token obtained in step 1 to authorize the call, and the consumer_key of your JS SDK app.
You now have an OAuth token for the current user. When generating the code being passed to the browser, have the client side JS SDK code first call yam.platform.getLoginStatus and if there’s no active session and you have a token from step 4, pass that token to yam.platform.setAuthToken($tokenFromStep4, optional_callback_function_if_desired(response)). If you don’t have a valid token, direct the user to finish setting up their Yammer account.
Continue making JS SDK calls as you normally would, without needing the user to authenticate.

I am using MobileServiceClient for authentication, my provider is Microsoft and Google. After success login in response I am getting auth Token and Sid. But I want more detail. I am using this service for Xamarin forms. Is there any way to get more detail of login user like email, username, verified_email, family_name etc?
Yes. Send a request to the /.auth/me endpoint with the X-ZUMO-AUTH header set to the ZUMO token. You will get back a JSON blob that contains all the claims plus the identity provider token. You can use these to get the information you need if it is available.
I wrote a PHP application which tries to create an User in my Google Directory. I don't use the Google Libraries. I succeded making requests to the Android Enterprise API. I can enroll and unenroll Enterprise Service Accounts with my MSA. So I assume my Code for the JWT and Requests work.
I created a Service Account and enabled "Domain Wide Delegation" and added the following permission "https://www.googleapis.com/auth/admin.directory.user, https://www.googleapis.com/auth/admin.directory.group" to my API Client under the "Manage API client access" windows.
My Service Account has the status role "Editor" in the "Permissions for project" windows.
So first my script gets the Bearer token from the Google Server, for that I create a JWT and encrypt it with my private key.
The Token contains the following fields
"iss" => sacname#projectname.iam.gserviceaccount.com
"scope" => "https://www.googleapis.com/auth/admin.directory.user, https://www.googleapis.com/auth/admin.directory.group"
"aud" => "https://www.googleapis.com/oauth2/v4/token",
"exp" => timestamp+3000,
"iat" => timestamp
When I do that request I get a bearer token, but when I use that token to make the insert request I always get the message "Not Authorized to access this resource/api" with an HTTP 403.
When I add the field "sub" to my JWT and specify the email of the Project admin "admin#mydomain.com" I can't even get the bearer token, then I get a 401 error with the following message "Unauthorized client or scope in request."
After that I tried something "easy", I just wanted to get a list of all users in my directory. But the Google Server just reponds with an "bad request" error. I got the same error with the API Explorer which is on API Page. Maybe the API is broken ? At least the API Explorer should work.

Do you have some ideas why I can't create users with my service account ?
(I had to insert some spaces in the scopes and urls because I'm not allowed to post more than two links)
Greetings
Philip
Adding the sub claim is the right thing to do, because you must impersonate a super admin to use Directory API. If you get a "Unauthorized client or scope in request" response, that might be because there's a typo in the service account client ID you used to authorize (or the scopes), or that not enough time has passed (it usually propagates within a few minutes, but could take up to 24 hours).
See JWT error codes for more details on possible errors and causes.
Do you have some ideas why I can't create users with my service account?
Yes. Your service account seems to have no authority to create users. Check your Service Account's role in GDC to check if it's Owner, Editor, Viewer,etc. The scope of what they can do depends on that. Watch this Google video for a live demo.
Also, try to read more on Using OAuth 2.0 for Server to Server Applications.
