Flo API Integration

With Terra's Flo integration, your app receives the cycles users track in Flo, one of the most widely used period-tracking apps. Terra normalizes each update, covering period start and end dates, cycle length and the symptoms users log, and POSTs it to your webhook.

Two ways to receive Flo data

When data is available from a Flo device, Terra sends it straight to your webhook. During your Terra account setup you'll be prompted for a callback URL, and that is where Terra POSTs each payload.

Flo does not notify Terra when data changes, so Terra polls it every 5–10 minutes for each connected user and POSTs the normalized payload to your webhook.

Flo's Menstruation
Payload Preview

Terra API preserves the raw data from the wearable, it just standardizes the units and the json format. It doesn’t augment or change the raw data in any way.

Data is organized into one of 6 data types.
