v1 action: log_expended_energy
Logging expended energy is most commonly used for step tracking. To accomplish this with the v2 API, make a POST request to /diary with type = steps, with a parent entry of type steps_aggregate.
Clients creating the first steps entry of a day may create the corresponding steps_aggregate entry in the same request, provided the steps_aggregate entry has an acceptable id property, and the chosen id value is set as the steps entry’s parent_id property. (If the chosen id property is not acceptable, the entire request will fail.)
The steps_aggregate entry may be created separately, of course.
