PowerApps Component Framework Authenticating REST API Call from ServerBackEnd Web Api

(0) ShareShare
ReportReport
Posted on by chigivigi08 5

I have a completed ServerBackEnd Web Api that receives requests from a frontend web application and returns a response for them.

My ServerBackend uses JWT Bearer tokens.

The purpose of my PCF is to replace the the frontend web application and send authorized requests to the backend.

 

I would like to avoid working in React as I am unfamiliar with the language and it would take too long to make a proof of concept.

Is there a way to authenticate those request inside the PCF without it ?

 

I made successful get request that did not require a bearer token using the fetch method inside PCF.

    You can create a PCF component that doesn't use React (most of mine don't)

     

    But I suspect your biggest issue won't be React is will be CORS - Cross-Origin Resource Sharing which may course you problems if you can't get the headers set correctly https://developer.mozilla.org/en-US/docs/Web/HTTP/CORS

     

    And if that's an issue the way I've got round CORS issues is to create a action within you PowerApp App that does the heavy lifting of talking to the serverbackend and handles the authentication requests - you then just need your pcf component to call the Action (and I'm sure I've posted code to do that here in the past).

     

    If however CORS isn't an issue https://medium.com/better-programming/authentication-and-authorization-using-jwt-with-node-js-4099b2e6ca1f shows you how to create a node application that handles JWT tokens

    I am using Azure AD authentication for my ServerBackend API.

    I apologize for not mentioning it earlier.

    So a JWT Token needs to come from there.
