Hello,
I am creating an application which will be using flowable open source. I want to make an authentification page(like ui authentification task app which exploits idm users). But I don’t found any flowable api rest to check password and username. Do I have to create it myself ? how if that was the case?
The open source Flowable UI applications don’t have a login page, if a user isn’t logged in they are redirected to the IDM application. After the user has successfully logged in they are redirected back to the Flowable UI application.
Yes ! you are totally right 
So i’ll make an independent module for authentication
thanks,
If you want to embed a Flowable engine in your application you can use an open source solution like Keycloak which supports OpenID Connect, SAML 2.0 and OAuth 2.0.
