All of your business data,
through one API.
An official REST interface for connecting external systems: members, leads, schedule and bookings, memberships, messages, tasks and reports. You create the key inside the app, without waiting for anyone.
Three steps
and you are live.
Connecting an external system to your business data: create a key, make a first call, then work against the API.
Create an API key
In the app: Business settings, API tab, create a key. Pick only the scopes the integration needs, and prefer read only to start with. The full key is shown once, so store it like a password. If the API is not open for the business yet, send an access request and we will open it.
First call
A 200 with your business id means the connection works.
curl https://web.featshare.com/api/v1/me \
-H "Authorization: Bearer fs_live_YOUR_KEY"Day to day
Read, sync and write. Every POST takes an Idempotency-Key so a retry never creates a duplicate.
curl "https://web.featshare.com/api/v1/members?limit=10" \
-H "Authorization: Bearer fs_live_YOUR_KEY"
curl "https://web.featshare.com/api/v1/schedule?from=2026-09-01&to=2026-09-07" \
-H "Authorization: Bearer fs_live_YOUR_KEY"
curl -X POST https://web.featshare.com/api/v1/leads \
-H "Authorization: Bearer fs_live_YOUR_KEY" \
-H "Content-Type: application/json" \
-H "Idempotency-Key: lead-42" \
