title: LinkedIn Signin for ios OAuth2, API V2. How to open the installed LinkedIn app
body: <p>Until now we have implemented an OAuth Workflow with mobile app and web-based login for LinkedIn with the help of (<a href="https://github.com/tonyli508/LinkedinSwift" rel="nofollow noreferrer">https://github.com/tonyli508/LinkedinSwift</a>). Due to LinkeIn API change to V2 on 1.3.2019 we updated our app to use browser-based OAuth 2.0 workflow for LinkedIn using REST-Interface API V2, an embedded UIWebView and intercepting the request to get the token, because LinkedinSwift uses the mobile ios SDK of LinkedIn and does not support API V2.</p>
  
  <p>The LinkeIn website for the SDK (<a href="https://developer.linkedin.com/docs/ios-sdk" rel="nofollow noreferrer">https://developer.linkedin.com/docs/ios-sdk</a>) says "The Mobile SDK is not currently supported". Following the Link, only the REST API is documented.</p>
  
  <p>Question:
  Did anybody manage to use a installed LinkedIn app for authorization and using API V2?</p>
