In the header of this Access Token, the kid attribute is missing.
{
"typ": "JWT",
"alg": "RS256",
"x5t": "oOvcz5M_7p-HjIKlFXz93u_V0Zo"
}
Is there anyway to have in the Azure DevOps Access Token the kid field ?
To get kid field in Azure DevOps access token, you can generate OAuth token using Azure AD to call DevOps REST API.
I tried to reproduce the same in my environment via Postman and got below results:
I registered one Azure AD application and added Azure DevOps permissions like below:
Make sure to grant admin consent to the permissions like below:
Now, I generated access token using client credentials flow via Postman with below parameters:
POST https://login.microsoftonline.com/<tenantID>/oauth2/v2.0/token
client_id: <appID>
grant_type:client_credentials
scope: https://app.vssps.visualstudio.com/.default
client_secret: <secret>
Response:
When I decoded the above access token in jwt.ms, I got kid field successfully like below:

I'm trying to query application insights via their REST API. I'm stuck on getting a token.
I have created an API key using the API Access blade in Azure Application Insights:
That gives you an Application ID and an API Key.
I have populated postman with the following:
url: https://login.microsoftonline.com/<Our Tenant ID>/oauth2/token
tenant: <Our Tenant ID>
client_id: <The Application ID from the API Access screen>
scope: https://api.applicationinsights.io/.default
client_secret: <The API Key from the API Access screen>
grant_type: client_credentials
All of this is taken from their documentation page here: https://learn.microsoft.com/en-us/azure/active-directory/develop/v2-oauth2-client-creds-grant-flow#get-a-token
The error is as follows:
"error": "unauthorized_client",
"error_description": "AADSTS700016: Application with identifier '<application ID from API Access screen>' was not found in the directory '<My Company Name>'. This can happen if the application has not been installed by the administrator of the tenant or consented to by any user in the tenant. You may have sent your authentication request to the wrong tenant.\r\nTrace ID: 57f78a92-fe94-40e3-a183-e3002be32801\r\nCorrelation ID: 0ab8e3ec-655d-44aa-93fa-4d3941862d11\r\nTimestamp: 2022-11-30 15:04:20Z",
I checked with the Azure Admin for our company and I'm definitely sending this to the right tenant. Also he created another key for me so it's not that either.
Thanks.
I tried to reproduce the same in my environment and got below results:
I created an API key from API Access blade in Azure Application Insights like below:
When I tried to acquire the token via Postman with below parameters, I got same error as below:
POST https://login.microsoftonline.com/<TenantID>/oauth2/token
client_id: <Application ID from API Access screen>
grant_type:client_credentials
client_secret: <API Key from API Access screen>
scope: https://api.applicationinsights.io/.default
Response:
There is no need to generate token separately if you want to query Application insights using API key.
Without including token, you can directly query Application insights by including x-api-key header like below:
GET https://api.applicationinsights.io/v1/apps/{Application ID from API Access screen}/metadata
x-api-key: <API Key from API Access screen>
Response:
The process you are currently following works only if you want to authenticate your API via Azure AD. In that case, you can generate the access token by granting required roles and scopes to registered Azure AD application.
But if your requirement is using API key, you can run any query by simply including x-api-key header for Authorization purpose.
I have created and registered an Application in Azure AD, which has multiple API permissions configured, among them Azure DevOps, the only available permission, user_impersonation.
I have successfully obtained an OAuth2 token via the full code flow, with requested scope of https://app.vssps.visualstudio.com/user_impersonation.
The access token is JWT, and I have decoded it:

So far so good. The important part here is aud that is the intended target for token which is "https://app.vssps.visualstudio.com" which is Azure DevOps service/resource.
I try to use is as a bearer token when calling Azure DevOps service:
e.g.
GET https://app.vssps.visualstudio.com/_apis/profile/profiles/me?api-version=6.1-preview.3
with header Authorization value Bearer eyJ0eXAiOiJKV1QiLCJhbGciOiJSUzI1N...
, I always get back a redirect to https://app.vssps.visualstudio.com/_signin?realm=app.vssps.visualstudio.com....., as if I wasn't authenticated.
Is there some step I am missing here? I have successfully called this endpoint with other types of authentication.
I am trying to update keyvault secret in Azure through Postman. But getting Authorization error.
Any suggestions. Anything I am missing. Thanks in advance
{
"error": {
"code": "Unauthorized",
"message": "AKV10022: Invalid audience. Expected https://vault.azure.net, found: https://management.azure.com/."
}
}
Using the below to update the secret:
PUT https://demokv.vault.azure.net/secrets/secretname?api-version=7.0
in Body:
{
"value": "mysecretvalue"
}
As mentioned in another reply, the audience of your token is not correct, to call Azure Keyvault REST API - Set Secret - Set Secret, the audience should be https://vault.azure.net.
To get the token, you could use the client credential flow in the postman.
1.Register an AD App in azure ad, then get values for signing in and create a new application secret.
2.Navigate to the keyvault in the portal, add the service principal of the AD App to the Access policies.
In the postman, follow the screenshot below, fix the properties that got from step 1.
POST https://login.microsoftonline.com/<tenant-id>/oauth2/v2.0/token
client_id=<client_id>
&scope=https://vault.azure.net/.default
&client_secret=<client_secret>
&grant_type=client_credentials
Then copy the token to call the REST API to set secret, it will work fine.
Also, you can get the token with az account get-access-token --resource "https://vault.azure.net"
To specificity vault resource
My challenge was using the older version of the oauth API.
Ensure that you're using:
POST https://login.microsoftonline.com/<tenant-id>/oauth2/v2.0/token
And not:
POST https://login.microsoftonline.com/<tenant-id>/oauth2/token
You acquired the access token (Bearer) for the wrong audience,
AKV10022: Invalid audience.
Expected https://vault.azure.net,
Found: https://management.azure.com/.
Acquire a new one for the correct audience and give it another go.
Here's the configuration for the Azure AD B2C, create two applications: web and api. added two scopes read and write to the api scope. configure web application to web application. tested with the built-in user flows e.g. sign up sign in. run the flow for the web app, get the access token, scopes are in the token.
now create a custom policy to use multitenants to authenticate the users with Azure AD. created a custom signup/in policy. run the policy, got the access token by specifying the api scopes in the access token, however the return token does not contain the scope claims. my question is how to configure the custom policy to have the api scopes in the access token?
When you run the custom policy, it will only return an ID token rather than access token.
So your scope claims won't be included in the ID token.
You should refer to Request an access token in Azure Active Directory B2C.
After you have Added a web API application to your Azure Active Directory B2C tenant, use authorization code flow to get the access token.
GET https://<tenant-name>.b2clogin.com/tfp/<tenant-name>.onmicrosoft.com/<policy-name>/oauth2/v2.0/authorize?
client_id=<application-ID>
&nonce=anyRandomValue
&redirect_uri=https://jwt.ms
&scope=https://<tenant-name>.onmicrosoft.com/api/read
&response_type=code
The response with the authorization code should be similar to this example:
https://jwt.ms/?code=eyJraWQiOiJjcGltY29yZV8wOTI1MjAxNSIsInZlciI6IjEuMC...
After successfully receiving the authorization code, you can use it to request an access token:
POST <tenant-name>.onmicrosoft.com/oauth2/v2.0/token?p=<policy-name> HTTP/1.1
Host: <tenant-name>.b2clogin.com
Content-Type: application/x-www-form-urlencoded
grant_type=authorization_code
&client_id=<application-ID>
&scope=https://<tenant-name>.onmicrosoft.com/api/read
&code=eyJraWQiOiJjcGltY29yZV8wOTI1MjAxNSIsInZlciI6IjEuMC...
&redirect_uri=https://jwt.ms
&client_secret=2hMG2-_:y12n10vwH...
The response:
{
"access_token": "eyJ0eXAiOiJKV1QiLCJhbGciOiJSUzI1NiIsImtpZCI6Ilg1ZVhrN...",
"token_type": "Bearer",
"not_before": 1549647431,
"expires_in": 3600,

I wanted to generate Azure token from Postman for API authorization in my project. I am able to generate token using below API request but getting the below error message "Authorization denied for this request" while using the generated token in another API request.
Endpoint#
https://login.microsoftonline.com/:tenant_id/oauth2/token
Params#
tenant_id:As per id generation by azure.
Body# (Form-data)
grant_type:client_credentials
client_id:As per id generation by azure.
client_secret:As per id generation by azure.
resource:Required URL
Response#
"token_type": "Bearer",
"expires_in": "foo",
"ext_expires_in": "foo",
"expires_on": "foo",
"not_before": "foo",
"resource": "foo",
"access_token":foo
Since the above returned token is not accepted, I had passed username and password as well in body of the request but ended up with same results. Also azure did not consider my credentials even they are wrong.
Could you please assist what else I need to send in the response to get valid token id?
The Valid format for client_credentials authentication flow is like below:

Expose Your Own API:
When You want to authorize your own API you have add it here. So that your token will contain this permission and this API can be accessed. Refer this docs
For more clarity you could refer official docs
You should try adding "X-ZUMO-AUTH" header to your request when using the generated token.
GET https://<appname>.azurewebsites.net/api/products/1
