There are several reasons why data is not returned from OData.
- The OData key you are using belongs to an admin account that has expired. For security reasons the key is blocked. Please contact the Aptem Support Team.
- The OData key has been mistyped in your query and therefore is rejected.
- The group access settings on the admin account assigned to the OData key do not have permission to view certain groups of learners, thus their data is not returned.
- Your OData query has not specified the column names for the required data. By default, on large tables only data for the first ten columns are returned.
- Where column names have been defined the query can be very long, this usually occurs with custom fields and skill radar fields in the Users table. For security reasons, the request URL cannot exceed 8000 characters. If it does then the query is blocked. The solution is to split the required columns into groups so that each query is less than 8000 characters.
