While creating Document, what is the action class invoked before DocumentAction class is invoked

Hi All,

I have a requirement and below is the scenario before creating a Document.

Make an external api call once "Publish" button clicked(as of now i have implemented in CreateDocumentStrategy).

(if external api returns true - complete the create document flow, if api returns false stay in same page and update the UI)

Question:-

Is CreateDocumentStrategy the right class to make an api call or any other action class?

In CreateDocumentStrategy class I could not get access to BaseContentActionBean to pass the api response value true/false to make the UI changes.

Please suggest the right approach.

Thanks
