What exactly is your usecase? Giving answers to such questions without knowing a usecase is often leading to the wrong direction and not helpful at all.
Yes the use case is that we want to integrate the aem dam with 3rd party dam but the client want to reverse the process and want to integrate 3rd party to aem so want to know it is possible or not if yes then how ?
what do you mean with "integrate"? What usecases do you need to support? Integration of a DAM into a DAM does not make that much sense, if no additional information are provided 🙂
