get the current scope of the users oauth token in Google API? - oauth-2.0

Is is possible to obtain the scope(Google API's) an Oauth token can access??
I have tried searching for it but no luck.
However facebook has something called as access token debugger which does the job does google have something similar to it ?

you can call Google's tokeninfo endpoint, as in:
curl https://www.googleapis.com/oauth2/v1/tokeninfo?access_token=<access_token>
and get back something similar to:
{
"issued_to": "<>
"audience": "<>
"user_id": "<>
"scope": "https://www.googleapis.com/auth/plus.me",
"expires_in": 3245,
"access_type": "offline"
}

Refresh token not present in response of Authorization API for multi tenant app

According to step 3 "Get a token" in https://learn.microsoft.com/en-us/graph/auth-v2-user
The API should return,
{
"token_type": "Bearer",
"scope": "user.read%20Fmail.read",
"expires_in": 3600,
"access_token": "eyJ0eXAiOiJKV1QiLCJhbGciOiJSUzI1NiIsIng1dCI6Ik5HVEZ2ZEstZnl0aEV1Q...",
"refresh_token": "AwABAAAAvPM1KaPlrEqdFSBzjqfTGAMxZGUTdM0t4B4..."
}
but it is returning, [Refresh token missing]
{
"token_type": "Bearer",
"scope": "user.read Fmail.read",
"expires_in": 3599,
"ext_expires_in": 3599,
"access_token": "eyJ0eXAiOiJKV1QiLCJub25jZ9...."
}
Can you please help with what am I missing?
You have to add offline_access to the scope to get a refresh token:
With the Microsoft identity platform endpoint, permissions are
requested using the scope parameter. In this example, the Microsoft
Graph permissions requested are for User.Read and Mail.Read, which
will allow the app to read the profile and mail of the signed-in user.
The offline_access permission is requested so that the app can get a
refresh token, which it can use to get a new access token when the
current one expires.

AcquireTokenForClient does not return a refresh token?

We are not receiving the refresh_token when requesting the token despite the documentation says that always you request a token you will receive a refresh token.
Might be accidentally missing/misunderstanding something ?
This is a piece of the code we are using:
var app = ConfidentialClientApplicationBuilder.Create("...")
.WithAuthority(AzureCloudInstance.AzurePublic, "...")
.WithClientSecret(CLIENTSECRET)
.Build();
AuthenticationResult result = await app.AcquireTokenForClient(ewsScopes)
.ExecuteAsync();
And here is the reference to the documentation that we are basing our expectation on:
https://learn.microsoft.com/en-us/azure/active-directory/develop/active-directory-configurable-token-lifetimes#refresh-tokens
Refresh tokens
When a client acquires an access token to access a protected resource, the client also receives a refresh token.
You are using Client Credentials flow here in your code here to acquire the token.
See here for documentation - IConfidentialClientApplication.AcquireTokenForClient(IEnumerable) Method
AuthenticationResult result = await app.AcquireTokenForClient(ewsScopes)
.ExecuteAsync();
Read here about the Client Credentials flow in more detail, and specifically what a successful response looks like in this case, which is only expected to have an access_token and no refresh_token.
{
"token_type": "Bearer",
"expires_in": 3599,
"access_token": "eyJ0eXAiOiJKV1QiLCJhbGciOiJSUzI1NiIsIng1dCI6Ik1uQ19WWmNBVGZNNXBP..."
}
A different flow, like Authorization Code flow (usually used by web apps) returns back an access_token as well as a refresh_token.
You can read more about that flow and a response in that case here - Authorization Code Flow

I haven't found documentation on what should i do with credentials part of this response? What should i use for user identification? What should be saved as token on client side (ios/android app) in order to revive the session? What does expires_in: 3600 means and what should i do about it? What does token_type: Bearer means and why do i need it? etc.
Thank you, #pinoyyid for clarifications!
The main thing i was looking for is this:
On server side get access_token property from credentials and verify it, using this url
https://www.googleapis.com/oauth2/v1/tokeninfo?access_token={your access_token}
Do whatever you want with the rest of the provided data.
Personally, i'll prefer to generate own token, save it on client side and use it to revive user's session (to verify his identity). Once token is lost for whatever reason, user just will go through the whole process again.
what should i do with credentials part of this response?
Rejoice, for you have done the hard part.
What should i use for user identification?
Anything you like, or nothing at all. It depends on your app's use case.
What should be saved as token on client side (ios/android app) in order to revive the session?
The Refresh Token. Note that "revive the session" is wrong terminology. In OAuth/REST, there are no sessions.
What does expires_in: 3600 means and what should i do about it?
It is saying that the Access Token will expire in 1 hour (3600 seconds). What you should do is use the Refresh Token to acquire a new Access Token by POSTing it as described https://developers.google.com/identity/protocols/OAuth2WebServer#offline
What does token_type: Bearer means?
It means the Access Token should be placed in an HTTP Authorization header whenever you try to access a Google API. Eg Authorization: "Bearer aaaaaaa" where aaaaaa is the Access Token.
and why do i need it?
To prove to Google that your app has been given permission to access a Google resource (eg. a file in Drive) by the owner of that resource.

Microsoft Account OpenID authentication token request returns id_token but not access_token

In the documentation at https://learn.microsoft.com/en-us/azure/active-directory/develop/active-directory-v2-protocols-oauth-code
... it states that a successful response to a token request looks like:
{
"access_token": "eyJ0eXAiOiJKV1QiLCJhbGciOiJSUzI1NiIsIng1dCI6Ik5HVEZ2ZEstZnl0aEV1Q...",
"token_type": "Bearer",
"expires_in": 3599,
"scope": "https%3A%2F%2Fgraph.microsoft.com%2Fmail.read",
"refresh_token": "AwABAAAAvPM1KaPlrEqdFSBzjqfTGAMxZGUTdM0t4B4...",
"id_token": "eyJ0eXAiOiJKV1QiLCJhbGciOiJub25lIn0.eyJhdWQiOiIyZDRkMTFhMi1mODE0LTQ2YTctOD...",
}
After the first step of authentication completes, I receive a code on the redirect and use it to request a token.
However, I only receive this:
{
"token_type": "Bearer",
"id_token": "eyJ0eXAiOiJKV1QiLCJhbGciOiJub25lIn0.eyJhdWQiOiIyZDRkMTFhMi1mODE0LTQ2YTctOD...",
}
My scope is set to openid email profile.
Why do I not receive the access_token?
Access token will be returned only when resource specific scopes are requested, so that it can used to access the protected resource. Try including a scope like "https://graph.microsoft.com/mail.read" as indicated in sample present in the documentation link posted with the question.

Testing with OAuth2 and Postman

I am using ZF2 Apigility and am working on setting up an OAuth2 workflow for an API I am writing.
So far I can get the following to work:
Call the API and get a token
{
"access_token": "62f6109dcbce42b38f9117b21529faf30fc0ee86",
"expires_in": 3600,
"token_type": "Bearer",
"scope": null
}
Now I know I need to use this token in the headers of my next request in order to access my API.
I am just not sure how to go about doing this with PostMan?
Click on Headers
then add
Authorization
as Header
and
Bearer 62f6109dcbce42b38f9117b21529faf30fc0ee86
as Value
