General Best Practices
Learn System Administrators should be enrolled in courses only using a non-Admin enabled user.
- System Administrator information is generally only available to 3LO Administrator requests.
Always monitor your API usage using the x-header information returned on non-oauth requests
- Details on rate_limits and x-headers are available here.
Not all data operations are best done Just-In-Time (JIT). Some operations, such as backfilling data warehouses or refreshing caches are best done during off-peak Learn hours.
- JIT calling or repeatedly calling for the same "static" data is inefficient.
- Checking whether a student is still in a course or getting their course grades are reasonable JIT activities as that is data that may change between now and their last access.
Cache infrequently changed or “static” data and refresh periodically.
- This reduces repetitive calls.
- This reduces integration performance impact.
- Don’t JIT retrieve ALL Courses for example as that data changes infrequently. Instead do this once and then periodically retrieve course data created or modified since you last request.
Always "optimize" your requests.
- reduce your “search” criteria to as small a set of data as possible.
- This limits the number of pages of returned data set.
- E.g. use
?dataSourceId=to reduce your search to objects created using a specific DSK and follow caching practices.
- Use the fields parameter to reduce the returned data set to only data points you require.
- This limits the data transmitted and system load
- reduce your “search” criteria to as small a set of data as possible.
Always try to logically bound your requests or before acting on request results:
- Check if dates are within bounds
- Check if attempts exist of if items are graded
- Check availability
Do not use Collection Gets to test for a specific object.
E.g.: don't use
GET /learn/api/public/v1/courses/{courseId}/usersto get all the course memberships to test if a student is enrolled.Instead use:
GET /learn/api/public/v1/courses/{courseId}/users/{userId}and branch your code based on the result.
