Trying to retrieve Okta token using postman but getting
"Invalid value for 'client_id' parameter."
I know the client_id is correct because it successfully works when I manually test my Azure function in Azure.
Plus, I can manually generate a token in Okta and then put that in the function call with client_id and client_secret in Postman and that works fine.
I'm using a Post http method.
I tried to reproduce the same in my environment and got the same error like below:
The error "Invalid value for 'client_id' parameter" usually occurs if you are passing invalid Client_ID value.
Make sure you are passing the values from the Okta Portal like below:
When I passed the correct values, I am able to generate the access token successfully using the below Parameters:
https://XXXX.okta.com/oauth2/default/v1/token
client_id:ClientId
client_secret:ClientSecret
grant_type:client_credentials
scope:scope
I created an Azure HTTP Trigger1, and selected the HTTP methods like below:
I am able to call the Azure Function Trigger successfully like below:
https://xxx.azurewebsites.net/api/HttpTrigger1
token:token
client_id:ClientID
client_secret:****

Today, I have an issue getting an Azure AD access token from Postman. This is while it was working before for the same app and other apps I am working on. But none of them are working today.
I was working correctly, but now it shows me this error:
Error: AADSTS900144: The request body must contain the following parameter: 'client_id'
I use https://login.microsoftonline.com/common/oauth2/v2.0/authorize as auth URL, and https://login.microsoftonline.com/common/v2.0/token for Access token URL.
I have tried these for access token URL but none of them worked. https://login.microsoftonline.com/{{tenant_id}}/v2.0/token
https://login.microsoftonline.com/common/token
https://login.microsoftonline.com/{tenant_id}/token
here is my Azure AD oauth 2.0 configuration. Also, as you see, there is no client_id in the request body.
I tried to reproduce the same in my environment and got below results
You can get values of auth URL and access token URL from your Azure AD application that varies based on supported account type like below:
Go to Azure Portal -> Azure Active Directory -> App registrations -> Your App -> Overview -> Endpoints
Now I added environment variables in Postman by defining them like below:
Make sure to select the correct Environment while requesting for token with variables.
I filled the required details same as you to get the access token like below:
When I selected Get New Access Token, I got the token successfully as below:
The error usually occurs if you missed including client_id while
acquiring access token.
I changed client_id parameter to blank in variables like below:
When I tried to get access token again, I got same error as you like below:
To resolve the error, make sure to pass client_id value in right environment and save it.
I found out why it's acting like this:
I checked my friend's PC, and it was working there!
The issue was the last update of Postman. They have changed something in authorization.
just change the Client Authentication to Send client credentials in body and it will work.
I am trying to grant access to IoT Hub based on Azure AD. But when I try to get token, it is throwing this error in Postman
####### Update ######
I have already created the Application in Azure AD
The resource field should be the static ID of all IoT Hub service principals. Try this instead of the hostname:
89d10474-74af-4874-99a7-c23c2f643083
Here is another approach:
I tried to reproduce the same in my environment and got the results successfully like below:
I created an Azure AD application like below:
To generate token via Postman, I used the below parameters:
POST https://login.microsoftonline.com/TenantID/oauth2/token
client_id:14ad98e6-8b3d-4774-a2ad-XXXXX
client_secret:XXXXXX
resource:https://iothubs.azure.net
grant_type:client_credentials
Response:
When I decoded the above token, I can see the aud as https://iothubs.azure.net like below:
The 400 Bad request error usually occurs if you have passed any invalid URL while generating the token. Make sure to pass the valid parameters.
Try sending the request again in Postman and check if the access token is generated or not.
Alternatively, you can also replace the resource by 89d10474-74af-4874-99a7-c23c2f643083 as suggested by Matthijs van der Veer like below:
Decoded token Response:
I have some troubles trying to call an Azure Function (code) with Postman.
I have already set up the Authentication / Authorization and settings.
It's working with my browser (with login page).
But when I try to use Postman, I'm getting 401 :
"You do not have permission to view this directory or page."
I also tried to use the Postman built-in (see configuration) Oauth2 to login. I can successfully get the tokens (access and refresh). But it seems that my API request to functions are not working...
Here is the final API Call: postman screenshot
The aad tenant_id starts with 8d6, the application client_id starts with 226, and the app secret ends with Av2.
Is there anything wrong ... ? It looks like actually, Azure Functions handle only Cookies for the authentication, that's why it's working with the browser and not Postman. How can I make it works with the header Authorization / Bearer ?
Thanks for your help !
The way you got the access token is not correct. Just like #Marc said, in your Postman you are not specifying a resource or scope. The postman get new access token tool only has the scope parameter, so you should use the v2.0 endpoint to get the access token.
Auth URL:
https://login.microsoftonline.com/{tenant}/oauth2/v2.0/authorize
Access Token URL:
https://login.microsoftonline.com/{tenant}/oauth2/v2.0/token
Scope:
{clientId}/.default
Following this guide: https://azure.microsoft.com/en-us/documentation/articles/resource-manager-api-authentication/#_get-objectid-of-application-service-principal-in-user-azure-ad
I've reached the stage where I call graph.windows.net to Get the ObjectId of the service principal in user Azure AD.
When I do the call, however, I'm getting the following message:
{"odata.error":{"code":"Authentication_MissingOrMalformed","message":{"lang":"en","value":"Access Token missing or malformed."},"values":null}}
I've already tried replacing the clientId with the 'onmicrosoft.com' address too (so graph.windows.net/appname.onmicrosoft.com/...), still got the same message.
To extend on my comment, we have seen this when the app secret contains characters that need encoding. Such as "+" and "="
If you are not using some of the client helpers available or are testing with Fiddler or Postman you will need to URL encode the secret before calling the graph api, so it looks it becomes:
"7hIkYG5m7xJQnocThxMc4yPjtbRP7bO41aNC%2bbrEzvo%3d"
I've been trying to use the Azure Service Management API in order to list the Hosted Services with no success.
In the first place, I was able to set up the authentication using PowerShell as the Microsoft documentation states here: https://msdn.microsoft.com/en-us/library/azure/dn790557.aspx
My first step was to request an access token using OAuth2 making a POST request to this URL:
https://login.windows.net/<MY_TENANT_ID>/oauth2/token
and passing these parameters:
grant_type: client_credentials
client_id: <THE_CLIENT_ID_OF_THE_APP_REGISTERED_THROUGH_POWERSHELL>
client_secret: <THE_PASSWORD_OF_APP_REGISTERED_THROUGH_POWERSHELL>
resource: https://management.core.windows.net
so, I receive a valid response and an access_token included in the response. So far so good.
Then, I want to make a simple call to the Management API; I would like to list my Hosted Services (Cloud Services), so I make a GET request to this URL:
https://management.core.windows.net/<MY_SUBSCRIPTION_ID>/services/hostedservices
Including the following headers:
Authorization: Bearer <THE_ACCESS_TOKEN_RECEIVED_IN_THE_PREVIOUS_STEP>
x-ms-version: 2014-10-01 (I've also tested with different versions)
but, what I get is a 401 Unauthorized error, with the following message:
The JWT token does not contain expected audience uri 'https://management.core.windows.net/'
I also tried with a Native Application registered directly in the Azure Portal (with Permissions set to use the Service Management API) and requesting a token using the grant_type = authorization_code. I get the access_token correctly and a refresh_token, but when I try to make a request to the above URL, I get the same error message.
On a side note, I am able to use the Azure Insights API successfully; the issue above is with the Azure Service Management API.
Anyone knows what I am missing?
I faced the same problem today. Complete the resource url with '/' https://management.core.windows.net
See the mismatch between the url in your resource and the one in the error message 'https://management.core.windows.net/'
