Hi,
I’m trying to build an workflow for orchestrating the SDK integration,
So we are fetching the data from an 3rd party application, which sends users data, The problem i’m enduring now is with the loop over item or i would recommend someone to help me how to orchestrate further,
Our SDK Integration Upload data supports only 1000 records/transaction per upload, but the API call has more than 1000+ user records, I have used Split out and set fields to customize the payload and I’m getting all user records as one item via the Aggregate node, I tried using loop node as well but same behavior. Can someone advice me how to orchestrate further to make sure we upload all the user data before finishing the sync?
