To delete a lesson, you need to pass required parameters, SID, safeKey, timeStamp, course ID and lesson Id. The API responses with error code and the description that you can refer to.

Notes: If you delete the lesson created with courseUniqueIdentity, the courseUniqueIdentity would also be deleted.
