Microsoft Power Automate does not provide digest authentication for HTTP requests out of the box.
However, to access an API with Power Automate, we need Digest Authentication. Has anyone ever implemented this and can give me some tips?

I have a Power App and Power Automate solution integrated with Docusign using their REST API's.
My issue is that I have users log into Docusign from a link which when completed and authenticated, returns an https response (authorization code) on the redirect uri. I want to be able to 'capture' the authorization code within Power Automate.
I want to avoid using custom connectors as they seem unreliable when using Oauth2 authentication and the users access token has expired. My preference is to use the HTTP REST API steps in Power Automate instead.
With a redirect to https://localhost:3000/auth/docusign/callback, I get the following https response:
https://localhost:3000/auth/docusign/callback?code=eyJ0eXAiOiJNVCIsImFsZyI6IlJTMjU2Iiwia2lkIjoiNjgxODVmZjEtNGU1MS00Y2U5LWFmMWMtNjg5ODEyMjAzMzE3In0.AQoAAAABAAYABwAAlzFclSfZSAgAACO4o5Un2UgCAOid-3Oz8jJHsDvIUG5hRR8VAAEAAAAYAAEAAAAFAAAADQAkAAAAZjA5Y2U4NDQtM2U5Yy00NjEzLTkwNzctNGY5MmFhY2NjZTc4IgAkAAAAZjA5Y2U4NDQtM2U5Yy00NjEzLTkwNzctNGY5MmFhY2NjZTc4NwBBDjKOCdhvSaNUWiI7O-21MAAAkAfAlCfZSA.zrYv2gsNFPVWHZpoO7-_5o4Ika3DxQpbNqlPUHiOvYFVL5igRnbZHh2V7OmN0bff7Tf14QF3pWaBAATozpIgzgj21m3ZjLbhY5J42eR1msXmoXjbBggibGC_FqbprVCzjSCvjbvMlwgEwda7LApdSWwr49ON9KhdN84qWD9sacJJvdi3Oi1KInImlVB_2rTpCLFhMD98PBv6b074yTqLOfwV31QT-6si8xLtk3G2vtn2gFZigXQxIA18b6tC-BM3NOILV1zwZNa1pstxxG2W8jJByUQlAux3d1GuS4vnDu_nr54mXULV0vY7txLFRiJA5w_E7Nlu2dlaOa5_DmfpNg
I want to intercept the code=eyJ0e........ in my flow.
I have tried setting up an http request and using the unique endpoint, used that as a redirect endpoint to send it to a receiving HTTP request flow. Docusign did not like the http request URL as a redirect.
I have to think this is a very simple thing to do and probably has to do with how the redirect/callback is configured in Power Automate. There maybe third party solutions that can act as a redirect intermediary which I can then GET with an API call. All ideas appreciated.
I have a working oauth2 application using v1.0 of Azure REST API. I am able to acquire access token via ADAL library for Java and no problem accessing their resources.
However, I wanted to know if there is a way to use this same token in order to let Office365/Outlook users to login on a web browser without entering a password ? Something like https://outlook.office365.com/token=abc..
This will help us to let users SSO on different devices without typing their passwords.
Technically, yes you can. You can try to leverage Microsoft Graph API to achieve your requirement.
Add the permission of Microsoft Graph in your AAD application, refer to https://graph.microsoft.io/en-us/docs/authorization/auth_overview for more info.
Follow OAuth2's Authorization Code Grant Flow to generate an access token, or leveraging your ADAL, please refer to https://graph.microsoft.io/en-us/docs/authorization/app_authorization for details.
Set the access token in the request header the same as you call Azure Rest APIs.
GET https://graph.microsoft.com/v1.0/users/john.doe#contoso.onmicrosoft.com HTTP/1.1
Authorization : Bearer <access_token>
For outlook APIs, you can refer to https://graph.microsoft.io/en-us/docs/api-reference/v1.0/resources/message for more info.
I have a need to authenticate against Azure Active Directory from a .net Web API. I read Vittorio Bertucci's article: Using ADAL .NET to Authenticate Users via Username/Password, and was wondering if there's any way of getting around the limitation of not being able to do this from a website/confidential client. He describes this as an AAD setting. Is it one that can be turned off?
Any assistance with this would be much appreciated!
This is not common scenario to use the Resource Owner Password Credentials in a web app. The recommend way is that using the Client Credential flow as Shawn Tabrizi suggested.
If you do want to use the Resource Owner Password Credentials flow, you can construct the request yourself as below:
POST: https://login.microsoftonline.com/xxxxx.onmicrosoft.com/oauth2/token
Content-Type: application/x-www-form-urlencoded
resource={resource}&client_id={clientId}&grant_type=password&username={userName}&password={password}&scope=openid&client_secret={clientSecret}
The Client Credential Flow (App Only Flow) should enable your confidential client to be able to authenticate to a downstream resource without a logged in user. This type of authentication is pure Service to Service Authentication, and will require only a secret for the client app to be presented either in the form of an App Key (symmetric key) or a Certificate Credential (asymmetric key).
However, all forms of access to an AAD Resource will require some form of initial interactive login. In the case of App Only Flows, you will need an Admin to perform an interactive login experience with the Client application, which will then allow subsequent user-less flows.
Check out these sample and let me know if it addresses your question!

I hope this helps!
I have a Web API written in C# and hosted in Azure with Azure API Management (AAM) sitting in front of that API and throttling requests.
The clients that call the API will be javascript based and will be calling on behalf of anonymous end users. For example, the home page of a web site might call our API via javascript to present information to an end user without asking them to login.
AAM ensures that callers to the API have a valid API key. There is the potential for this key to be copied and abused though if someone grabs it from the publicly visible source.
Is it possible to use OAuth2 to obtain a JWT Access Token without human intervention and for this to be exposed on the client?
OAuth2 can issue expiring JSON Web Tokens which would lower the risk of token theft, but I'm struggling to get this going without any human intervention.
OAuth2 is mostly about end user initiated authorisation but IdentityServer3 seems to have a Hybrid approach. Could I use this Hybrid approach to get the remote web server to request a token by sending the API key from server to server first and then outputting the JWT in the web page for use by the client side script?
This would then hide the API key and only show a JWT that is of use for a few minutes.
AAM can integrate with OAuth2 and inspects JWT Access Tokens, but I don't think it understands this Hybrid flow (it may not need to as we won't be asking for user logins).
Or should I just give up and rate limit requests only?
If you can generate these hybrid JWT keys without user intervention then API Management can validate them and use one of the claims as a key for doing rate limiting. Normally rate limiting is done based on API Management subscription keys, but the new advanced rate limiting policies allow you rate limit based on any expression.
I'm not familiar with how the IdentityServer hybrid mode keys work, but usually if there is non-interactive login, then there is some kind of secret that needs to be protected. This is always a challenge when running code on the client.
The API Management HTTP API does have a method to regenerate keys. You could use this to implement your own token expiry mechanism to limit the impact of key theft.
I want to download a file using BITS or any other asynchronous file download winapi. Can anyone suggest any method to identify the proxy authentication scheme on server so that I can act accordingly in my application. (For ex. either its NTLM or Kerberos or simple Basic Authentication, Digest Authentication or Passport ... etc. )
