Hello Meghna,
You need to start and finish your transaction in your first microflow before you can retrieve it with the REST in the other.
You can use for this the object handling actions;
Start transaction and end transaction:

Hope this helps,
Good luck!
Hi Meghna,
I don't know whether it works or not, Check with this suggestion.
Use After Commit Event and keep that REST Call in that microflow to retrieve that object.
Correct me if I'm wrong.
