What is the difference between body and daily payloads?

Daily and Body payloads cover different things, with some deliberate overlap.

Daily and Body payloads cover different things, with some deliberate overlap.

• Daily payloads are per-calendar-day summaries of activity and health metrics, and update throughout the day.

• Body payloads contain body-specific measurements (weigh-ins, blood glucose, and so on), sent whenever the user records a new measurement.

Metrics that appear in both (HR, RHR, HRV, SpO2, VO2 max, and similar) carry the same values in either payload, so you can read them from whichever is more convenient. If you only need daily metrics, you can consume Daily alone without missing data.
