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.

How the Flo API integration works

Data delivery: Terra polls Flo
Expected latency: Up to 5–10 minutes after the provider syncs
Data types: Menstruation, normalized by the Terra unified API
Credentials: No provider credentials required

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.

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.

People Often Ask Us...

How do I access Flo cycle data through an API?

Your user connects their Flo account through the Terra widget, and Terra reads the cycles they track, normalizing each update into its standard Menstruation payload and POSTing it to your webhook.

How quickly does Flo data reach my app?

Terra polls Flo every 5–10 minutes for each connected user, so new data reaches your webhook within that window of a device sync.

What data is available from Flo through Terra?

Through Terra's Flo integration, you can access menstruation data.

What menstrual data does the Flo integration return?

Period start and end dates, cycle length and the symptoms users log in Flo — the same normalized Menstruation shape Terra uses for every other cycle-tracking source, so you write the feature once.

Do I need Flo API credentials?

No provider credentials are required. Users authenticate with their own Flo login through the Terra widget.
