Flowsery Analytics

Privacy-first web analytics. Query real-time visitors, breakdowns, time series, revenue, goals, and visitor profiles — all via one API.

Setup

1. Sign up at https://flowsery.com/signup
2. Add your website and install the tracking snippet
3. Go to Site Settings → API tab → generate an API key
4. Set the environment variable:

   export FLOWSERY_API_KEY="flow_sk_live_your-token-here"

Base URL: https://analytics.flowsery.com/api/v1 Auth header: Authorization: Bearer $FLOWSERY_API_KEY

All API keys use the flow_ prefix (e.g. flow_sk_live_abc123). Treat them like passwords — never expose in client-side code.

Core Workflow

1. Check website metadata

curl -s -H "Authorization: Bearer $FLOWSERY_API_KEY" \
  https://analytics.flowsery.com/api/v1/metadata

Returns { "status": "success", "data": [{ "domain", "timezone", "name", "logo", "kpiColorScheme", "kpi", "currency" }] }. Use the timezone and currency values for subsequent queries.

2. Get site overview (aggregated metrics)

curl -s -H "Authorization: Bearer $FLOWSERY_API_KEY" \
  "https://analytics.flowsery.com/api/v1/overview?startAt=2026-01-01&endAt=2026-01-31&timezone=America/New_York"

Returns: visitors, sessions, bounce_rate, avg_session_duration, revenue, revenue_per_visitor, conversion_rate.

Omit date params for all-time data. Use fields param to select specific metrics: ?fields=visitors,revenue.

3. Get time series data

curl -s -H "Authorization: Bearer $FLOWSERY_API_KEY" \
  "https://analytics.flowsery.com/api/v1/timeseries?interval=day&fields=visitors,sessions,revenue&startAt=2026-03-01&endAt=2026-03-31"

Intervals: hour, day, week, month. Returns timestamped data buckets with totals.

Response includes data array, totals object (with visitors, sessions, revenue, revenueBreakdown), and pagination.

4. Check real-time visitors

curl -s -H "Authorization: Bearer $FLOWSERY_API_KEY" \
  https://analytics.flowsery.com/api/v1/realtime

Returns { "data": [{ "visitors": 42 }] } — active visitors in the last 5 minutes.

For geographic data, use the map endpoint:

curl -s -H "Authorization: Bearer $FLOWSERY_API_KEY" \
  https://analytics.flowsery.com/api/v1/realtime/map

5. Get breakdown reports

Each returns top items for a dimension with visitor/session counts. All accept date range, pagination, and filter params.

# Top pages
curl -s -H "Authorization: Bearer $FLOWSERY_API_KEY" \
  "https://analytics.flowsery.com/api/v1/pages?startAt=2026-03-01&endAt=2026-03-31&limit=20"

# Top referrers
curl -s -H "Authorization: Bearer $FLOWSERY_API_KEY" \
  "https://analytics.flowsery.com/api/v1/referrers?startAt=2026-03-01&endAt=2026-03-31"

# Countries
curl -s -H "Authorization: Bearer $FLOWSERY_API_KEY" \
  "https://analytics.flowsery.com/api/v1/countries?startAt=2026-03-01&endAt=2026-03-31"

# Devices (desktop/mobile/tablet)
curl -s -H "Authorization: Bearer $FLOWSERY_API_KEY" \
  "https://analytics.flowsery.com/api/v1/devices?startAt=2026-03-01&endAt=2026-03-31"

# Marketing channels
curl -s -H "Authorization: Bearer $FLOWSERY_API_KEY" \
  "https://analytics.flowsery.com/api/v1/channels?startAt=2026-03-01&endAt=2026-03-31"

Available breakdown endpoints: pages, referrers, countries, regions, cities, devices, browsers, operating-systems, campaigns, hostnames, channels, goals.

For any dimension, use the generic breakdown:

curl -s -H "Authorization: Bearer $FLOWSERY_API_KEY" \
  "https://analytics.flowsery.com/api/v1/breakdown?dimension=utm_source&startAt=2026-03-01&endAt=2026-03-31"

See references/breakdown-dimensions.md for all 24 dimensions.

6. Get a visitor profile

curl -s -H "Authorization: Bearer $FLOWSERY_API_KEY" \
  https://analytics.flowsery.com/api/v1/visitors/VISITOR_ID_HERE

Returns comprehensive visitor data:

• identity: country, region, city, browser, OS, device type, viewport
• source: original traffic source with favicon URL
• activity: visit count, page views, first/last visit, visited pages, completed goals
• revenue: total revenue, customer flag, time to first conversion (seconds)
• profile: identified user data (userId, name, email) or null for anonymous visitors
• activityTimeline: merged chronological list of all pageviews, goals, and payments

The visitor ID comes from the _fs_vid browser cookie set by the Flowsery tracking script.

7. Track a custom goal

curl -X POST https://analytics.flowsery.com/api/v1/goals \
  -H "Authorization: Bearer $FLOWSERY_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "visitorUid": "VISITOR_UID_FROM_COOKIE",
    "name": "newsletter_signup",
    "metadata": { "plan": "pro", "source": "pricing_page" }
  }'

• name (required): lowercase letters, numbers, underscores, hyphens; max 64 chars
• visitorUid (recommended): from the _fs_vid browser cookie
• metadata (optional): up to 10 key-value pairs (keys: lowercase, max 64 chars; values: max 255 chars)

The visitor must have at least one recorded pageview before a goal can be created.

8. Record a payment

If you use Stripe, LemonSqueezy, or Polar, payments are tracked automatically when connected. Use this endpoint only for other providers.

curl -X POST https://analytics.flowsery.com/api/v1/payments \
  -H "Authorization: Bearer $FLOWSERY_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "amount": 29.99,
    "currency": "USD",
    "transactionId": "payment_456",
    "visitorUid": "VISITOR_UID_FROM_COOKIE",
    "email": "customer@example.com"
  }'

Required: amount, currency, transactionId. Optional: visitorUid, sessionUid, email, name, customerId, isRenewal (boolean), isRefund (boolean).

9. Delete goal events

curl -X DELETE "https://analytics.flowsery.com/api/v1/goals?name=signup&startAt=2026-01-01T00:00:00Z&endAt=2026-01-31T23:59:59Z" \
  -H "Authorization: Bearer $FLOWSERY_API_KEY"

At least one filter required: visitorId, name, startAt, endAt.

10. Delete payment records

curl -X DELETE "https://analytics.flowsery.com/api/v1/payments?transactionId=payment_456" \
  -H "Authorization: Bearer $FLOWSERY_API_KEY"

Tips for the Agent

Read-only by default

Most commands are safe GET queries. The only write operations are:

• POST /goals — track a goal event
• POST /payments — record a payment
• DELETE /goals — delete goal events (irreversible)
• DELETE /payments — delete payment records (irreversible)

Always confirm with the user before running DELETE operations.

Date handling

• When the user says "this month", "last week", "yesterday" — calculate the actual ISO dates
• Default to the last 30 days when no date range is specified
• Always use UTC or the site's timezone (from the metadata endpoint)

Revenue data is sensitive

When displaying payment or revenue data, ask the user about the appropriate level of detail before dumping raw numbers.

Polling

Do not poll the realtime endpoint more than once per 5 seconds.
