Hi,Is it possible to use the general Web API from a Power Platform Portal (not the portal web api)?I want to perform a batch operation with the Web API coming from a portal but I'm struggling with the authentication.Thanks
You haven't disclosed enough information to adequately answer this. Technically, probably yes but I don't know that I would recommend it or if there is a better way to achieve what you want to do - I suspect there is a more appropriate way to achieve what you may want.
You would need to treat the portal as though it was a stand alone page https://docs.microsoft.com/en-us/power-apps/developer/data-platform/webapi/authenticate-web-api#authenticate-with-javascript-in-web-resources using the adal.js library. https://docs.microsoft.com/en-us/power-apps/developer/data-platform/oauth-cross-origin-resource-sharing-connect-single-page-application
Thanks for your response.Authentication in the portal is currently done with Azure AD.Is it possible for example to use a user token that is obtained with [portal-url]/_services/auth/token?Ideally I would like to retrieve a token in the background without any user interaction as they are already logged in to access the portal.
if you get a token from the portal it will not work with the Dataverse Web API because the context is different.
Keep in mind that the authentication against a Portals is done with contacts, against Dataverse is done against users and app registrations.
@GuidoPreiteSo is there any way I can retrieve a token for the Dataverse Web API from the browser without user interaction?Thanks
as I wrote before the context of a Portal is different, I am not aware of way to get a Dataverse token without user interaction starting from a Portal user
If the user is logged into the Portal you could look into the Portals support of Implicit Grant Flow. https://docs.microsoft.com/en-us/power-apps/maker/portals/oauth-implicit-grant-flow
Not sure why you need batch from the portal so it is difficult to provide an answer - if we know why, may be able to suggest other options.
have you considered using Azure Functions? does your process have to run on a Batch operation?
is that a sync/async operation? from a Web Portal perspective, a large operation should always be done in the background, otherwise the user might be stuck waiting for the response
@OliverRodrigues We are trying to avoid Azure Functions at this time. At a certain point I need to create up to 2000 records. The user needs to wait until they have been created as those records are needed in the next step. I was able to retrieve a working token with the MSAL.JS library.
