Is there a way to direct the user to the login page when trying to access a web api when they are not logged in? Currently with IE it&#39;s prompting: &quot;Do you want to save &lt;weben-USTelligent Community 12https://community.appian.com/thread/50580?ContentTypeID=1Fri, 01 Dec 2017 21:59:48 GMTd3a83456-d57b-489c-a84c-4e8267bb592a:9dbe8447-dd04-4ff5-99f6-ff43595041d7aloks0189Hi as per my understanding, WEB-API is meant for exposing Appian Data outside the world. When a 3rd Party System wants to interact with Appian Data/Process then need to make the use of Web-API where they can pass the required parameter/body of API (if any)<br /> <br /> <br /> While invoking WEB-API from third party system, they need to use Basic Authentication to avoid HTTP Error 401: Unauthorized, but Web-API is not meant for redirection to login page.<br /> <br /> In order to achieve login requirement, you need to build Servlet-Plugin which can redirect you to login page.<br /> <br /> Hope this will help you.<div style="clear:both;"></div>
