It appears via the OneDrive API documentation that a user must always "authenticate" using a web-browser to access the OneDrive API. This is not helpful for system accounts. Am I interpreting this correctly? Or is there a way to achieve step one without a browser:
Step 1. Get an authorization code
To start the sign-in process with the code flow, use a web browser or web-browser control to load this URL request.
GET https://login.microsoftonline.com/common/oauth2/v2.0/authorize?client_id={client_id}&scope={scope}
&response_type=code&redirect_uri={redirect_uri}
https://dev.onedrive.com/auth/graph_oauth.htm#code-flow
What you're looking for is an App-Only integration. See Get access without a user for details on how this process works.
Keep in mind that there are scope differences between app-only and delegated scenarios. Also, app-only scenarios will require Admin Consent before they can operate against a given tenant (see v2 Endpoint and Admin Consent).

I am building an app which authenticates via microsoft and needs various that predominantly uses Delegated permissions. I use the v2 auth endpoints to do incremental authentication, only asking for additional scopes when the user needs them.
This has worked well for the many delegated permissions I have so far. In many cases I need admin approval for these permissions, but I have a flow for that which works well.
One of the scopes I have used as a delegated permission is "User.Read.All", I now need the same scope on the application permission level. But I am struggling to work out if there is a way to do incremental authentication for application permissions. The docs say to use the generic endpoint where you don't specify scopes, but this then asks for all the scopes I have on my application registration rather than just passing in the scopes as a param.
It has nothing do with the endpoint and the scopes you specified. Since you use Delegated permissions in your original job, so I consider you use auth code flow or username/passord flow. If we use auth code flow or username/password flow, we can't get application permission when we do authentication although you have assign the application permissions to your registered app. If you want to get application permission when do authentication, you need to use client credential flow instead.
It is not possible to do this unfortunately the consent flow allows either a dynamic set of delegated scopes to be submitted or /.default which acts like the v1 endpoints and requests all scopes for that client. See these docs
I'm having difficulties finding documentation for auth0 and microsoft graph integration. My end goal is to have a SPA that can login with a microsoft profile to auth0 (connected to azure ad). Then I want my app to get a token for microsoft graph and do some api calls.
As I've understood it so far, auth0 does not allow you to get the access token to different identity providers in a front end application, but rather that they should use a proxy to get this token. My flow therefore is:
I login with a SPA auth0 app (using a microsoft identity)
This is then used to authenticate to a backend server using a api registration in auth0
The backend has its seperate machine-to-machine app in auth0
Backend api uses this seperate app to get access token to auth0 management api
Current user is fetched (based on the logged in user from front end app login) from management api,
Here i find an access token under the azure identity (if I do the same in the front end, the access tokens are omitted)
Token does not work to call graph, I am unsure of where to send it next.
I am aware that the above is probably completely wrong, that's why I am here :)
My questions are:
1) Is it even possible to get an access token for microsoft graph starting from a login to auth0 in the way I want it to. If not, can it be done from a backend?
2) Does anyone have a link that discusses this, ideally with some code samples.
To answer your first question:
1) Is it even possible to get an access token for microsoft graph starting from a login to auth0 in the way I want it to. If not, can it be done from a backend?
I have had the chance to authenticate apps using the microsoft identity library called MSAl whose documentation is found here. It gives a pretty detailed way to authenticate directly from your SPA.
I have also used the microsoft javascript sdk as it comes inbuilt with token caching and refreshing so that I do not need to build that for myself.
In relation to this,
Does anyone have a link that discusses this, ideally with some code samples.
You can find the samples well described in the samples section of the SDK
I hope this helps.
I have a JavaScript app that requires a user to login and hit a button then it runs a report, posts data to Excel, and sends an email. I want to automate this so a user does not have to log in and push a button.
I started with this project code: https://github.com/microsoftgraph/nodejs-apponlytoken-rest-sample
I followed the instructions and am able to get an access token but then my api call fails with 401 unauthorized. As a test, I am trying to send an email as myself and I have the Application type Mail.Send permission granted by the company admin.
I have spent many hours reading docs and blogs but have not found a solution. This document summarizes best what I am troubleshooting: https://blogs.technet.microsoft.com/sharepointdevelopersupport/2018/03/15/troubleshooting-assistance-with-microsoft-graph-api-development/.
The token I get back does not have any Roles in it as seen when I decode it with JWT. This is the only discrepancy I have found so far.
Any advise would be greatly appreciated. How can I ensure that my token has Roles defined or what else can I try? How is it that I can get a token successfully but can't use it for anything?
Thank you!
I am not a Node expert, so helping you out with a few pointers that might help.
Microsoft Graph has two types of permissions, Delegated and Application. So some things to know of and check..
Delegated permissions require a user to be present, they would show up in the scp claim in the access token. These are obtained by web applications using the implicit_grant flow, Authorization code grant or on-behalf-of flow (usually).
Application Permissions, require an admin to consent and will be provided to you in the roles claim in the access token. This requires, the app to obtain an access token via the client credentials grant. Note that, these are also present when the user is assigned a role as explained in this sample, but this scenario might not be applicable for in your case.
Does you app has the grant provided as you expect? You can check these via the Graph Explorer using the following two rest calls. There would be a OAuth2PermissionGrant entry with the expected role in it.
https://graph.microsoft.com/beta/OAuth2PermissionGrants
https://graph.microsoft.com/beta/kalyankrishna.net/OAuth2PermissionGrants
It'd help more if you can explain the flow that you have been using to obtain the access token. For example, the implicit_grant_flow does not work with application permissions.
In my case, the problem had to do with the endpoint and my tenant. I had been using the common tenant make api calls for tokens because that is what was listed in AzureAD for my app. I found that for the Application client permissions I must use my specific tenant id like 'https://login.microsoftonline.com/tenant_id/oauth2/token' when getting tokens with the proper roles.
New to Oauth and had a general question. Is there a way to restrict who can log into your site with Oauth 2? Similar to AD groups or something so I could control who I want to be able to log in based on group or user name? I would like people to use google or facebook but only let certain people actually log in.
You can filter users in a code that handles the redirect_uri. If you use the Auth code grant, that will be some backend code and if you use the Implicit flow, it will be a code in a browser application. But the JavaScript security restrictions should have their equivalent somewhere at the backend too, since the JavaScript code can be altered by the browser user.
To be able to do that (to have info about an authenticated user), you should either request an ID token or an access token with a scope that authorizes you to get user info at the /userinfo endpoint.
I configured an application on AzureAd to be multi-tenant, I chose to require all the permissions for Windows Azure Active Directory and Office 365 Exchange Online.
I can get a user to grant permissions, get access tokens, refresh them, OAuth works for me. I always used the "common" keyword instead of the tenant ID, because my app is multi-tenant.
Now, I would like to have (CRUD) access to a user's Mail, Contacts and Calendar with this token. Here is my problem: I am completely lost in all the possible API endpoints. Should I use: graph.windows.net, outlook.office365.com, graph.microsoft.com? This page seems to suggest that graph.microsoft.com is the Swiss army knife that would serve my purpose, but somehow I cannot find a doc that allows me to find the info I'm looking for. Plus, it seems under development and maybe too incomplete for what I want.
If I make queries against outlook.office365.com, I've got a 401 error.
If I put my access token in this token analyzer, it seems healthy although the scope field only shows the permissions I set in the AzureAd portal for Windows Azure Active Directory, not Office 365 Exchange Online.
I am kind of lost, any help would be welcome...
You have a choice:
Call the separate service apis - Your problem is that you acquired a token to call AAD, and then tried to use that to call Outlook - you need to make a separate call to acquire a token for outlook.office365.com through ADAL or through the token endpoint directly. The token acquired for AAD Graph can ONLY be used against AAD Graph. Similarly the token acquired for Outlook can ONLY be used against Outlook APIs.
Just to clarify - Azure AD OAuth can protect/secure multiple web APIs, including O365 APIs, Azure AD Graph, Azure Resource Management APIs, your own APIs and the new O365 unified API. In the first access token request, you specify the first resource you want/need to call. It doesn't have to be AAD Graph - i.e. it's not the default AFAIK. Based on what is consented to, you have the ability to request additional access tokens using the (multi-resource) refresh token. Vittorio's blog post which you link to in your comments does a great job explaining this.
Call the O365 unified API (which is in preview) and IS documented. See below. The beauty of the unified API is that you only need to acquire a token to call graph.microsoft.com and ALL the entities on that endpoint are available to you AND more. It removes the siloed nature of #1, and the requirement to get and manage multiple access tokens to call these different API endpoints. However #1 is currently GA, and the unified API is preview only at this time.
For more on #2 please see https://msdn.microsoft.com/en-us/office/office365/howto/office-365-unified-api-overview and search for "unified" in the list of samples here: https://msdn.microsoft.com/en-us/office/office365/howto/starter-projects-and-code-samples
We are working on improving the unified API documentation. If you are making pure REST calls, then I recommend starting out with the API explorer (and try things like https://graph.microsoft.com/beta/me/events and https://graph.microsoft.com/beta/me/messages to get your calendar events and mail messages), OR the API sandbox (which can show you JS code snippets, and allow you to test your own easily enough). As you can see on the REST examples, to access mail and calendar features in the unified APIs, you should be able to swap the service roots from Outlook to the unified API ie - https://outlook.office365.com/v1.0 -> https://graph.microsoft.com/beta. On the JS sample - we will be adding more capabilities here and additional samples.
NOTE: Personal contacts available in outlook.office365.com are not available in the unified API yet.
Hope this helps
