Communication between Alfresco APIs and Gateway level (Middleware) with Authentication

[Tabu]

Hi, 

We have a plan, where in our front end application can access all the Alfresco APIs through middleware (gateway level).

Middleware would have it's own authentication but as Alfresco has authentication of generating a ticket, we are using the same mechanism in our front end, to complete some of the operations related to Alfresco.

Now, we are facing a challenge in creating communication between the middleware and Alfresco APIs with the authentication.

Any suggestions would be appreciated. Thank you!
