+Usage of the bulk-update API
+============================
+
+Context
+=======
+
+The LMS Grades API exposes a set of Gradebook-related endpoints:
+https://github.com/edx/edx-platform/blob/master/lms/djangoapps/grades/api/v1/gradebook_views.py
+The ``bulk-update`` endpoint defined therein allows for the creation/modification of subsection
+grades for multiple users and sections in a single request.  This allows clients of the API to limit
+the number of network requests made and to more easily manage client-side data.  Moreover,
+the course grade updates that occur during calls to this API are synchronous - the entire update operation
+is completed before a response is given to the client.
+
+For decisions made about the implementation of this API, see:
+https://github.com/edx/edx-platform/blob/master/lms/djangoapps/grades/docs/decisions/0001-gradebook-api.rst
+
+Decision
+========
+
+The Gradebook front-end will post data about a single subsection and user in a single request
+to the ``bulk-update`` API.  That is, we currently need only the "update" aspect of this
+endpoint, and not the "bulk" aspect, for satisfying the requirements of the current UX.
+
+Status
+======
+
+Accepted (circa December 2018)
+
+Consequences
+============
+
+This is a scenario in which the implementation of the API is coupled to the
+UX that depends on the API.  Because the course grade update is synchronous, it means
+the API response can contain the updated subsection and course grade data.  Because
+a response from the API contains this data, the UI can operate in a very familiar way:
+
+- A user clicks a button to submit a request with grade update data to the update endpoint.
+- On the server, the subsection and course grades are modified.
+- In the meantime, the client-side user looks at a spinner.
+- A response is returned with updated data and the spinner goes away.
+- Updated data is displayed to the user, along with a message indicative of the update.
+
+If the update becomes asynchronous, the user experience outlined above has to change.
+Because a single call to this endpoint updates grades data for only a single user,
+the endpoint does not necessarily have to utilize an asynchronous operation at this time.
