Efficiently Retrieving Data Changes (Deltas) from EthosCE API

Our team needs to regularly update our system with changes (deltas) from EthosCE. We want to ensure this process is efficient and doesn’t overburden the EthosCE API, as well as take as long as it does to refresh our system. Could anyone share best practices or strategies for fetching data changes? Are there specific endpoints designed for this purpose, or recommended methods to minimize API load?
