I am trying to access nested Json Structure like I have a entity A which is in 1-1 relation with entity B and B has 1-many relation with entity C. Now I want to access the data of C entity through RestAPI. When I hit the API it fills all the data but only shows Entity A data. So can anybody suggest how should I access the data of entity C? I have tried doing the A/B/C relation but it is not working .
You have to retrieve the association A→B first use the Retrieve action. Then use Retrieve action again to retrieve all C objects from entity B.
