It’s a mistake. The functionality of the Endpoint provider has been merged into the new OData provider, but the Endpoint provider is only deprecated for DW10. You can wait for the next release or use the new OData provider which has the same functionality of the Endpoint provider and much more, consuming not just BC endpoint, but also F&O and CRM. You can read about the old and new version here: https://doc.dynamicweb.com/documentation-9/integration/integration-framework/data-integration-activities#sideNavTitle1-2
