I want to create a Powerapp to connect to the Cisco Webex API to get a list of attendees for a meeting. To do this I need to use an Integration (in Webex termnology - similar to an Azure app integration) which uses Oauth. The workflow is that the user clicks on a link to Cisco (with a redirect URL of an app as a parameter) . The user logs in to Webex, grants the required permissions, and the response goes to the specified redirect URL. There is a second exchange before the Bearer token is granted. I have successfully created a Flow that acts as the application at the redirect URL, and that gets the bearer token in a response from Cisco. My problem is how to return that token to the Power app. I cannot call the Flow from the Power app directly, as the user needs to login to Webex with the browser, and the Flow does not run as the user so I do not think I can return the value that way. If I start with the browser, I do not know of a way of triggering a Power App from a Flow. Cisco's workflow seems to be aimed at a Web Application that will do all the work, I feel I must be missing something simple!
