Hi @PoojaMudgal
not sure I fully understand your question or requirements.
Let's say how you integrate Adobe Target largely depends on your current setup and how much time you have to integrate it.
Modern but with higher integration complexity - Web SDK
The modern way to implement it is by using Web SDK and connecting Adobe Target to your configured datastream.
This is typically done through a tag manager like Adobe Data Collection (former Launch)
Web SDK replaces the legacy Adobe libraries for Analytics, Target, Audience Manager and Visitor ID Service with one single library that is a lot more lightweight than the combined individual libraries. It comes with a learning curve though.

Classic Approach - at.js
However, the classic / legacy library "at.js" can still be used. But keep in mind that it can happen that Adobe decides to phase out the legacy libraries in the future.
