Facing performance issue of OIC integration if we use a REST API for pushing Learning Records DFF.

We are facing performance issue of OIC integration if we use this API-

Module- Oracle Learning Management-

/hcmRestApi/resources/11.13.18.05/learnerLearningRecords/{learnerLearningRecordsUniqID}/child/primarySelectedCourseOffering/{primarySelectedCourseOfferingUniqID}/child/assignmentDFF/{RequestDetailID}

Also, this API cannot be accessed directly, we require 4 API GET calls to go to this, and hence increasing the time for a single record.

Please provide a direct API where we can POST/ PATCH Learning Records DFF data.

We created an OIC Integration to POST the Learning Records DFF data for a learner but due to multiple API calls, the integration is taking 3.5 hours for 1000 records and after that it stops.
