Conect and navigate on an other app via API


I am new on Adalo, and i am triying to use Adalo to create the Basic front of my aplications and connect thata basic application to others plugins that we develop in intern.

example: the user submit a document and click an sign document → with a customer actions and a call to the API go to my plugin and process the document → at the end of the use of the plugin, go back to my adalo app and send back the doument signed via API

Is that possible to do somenting like that ??

Thanks a lot for your help, Hugues
