clamp-analytics 0.1.0

Server-side analytics SDK for Clamp. Send tracked events from Python apps (Django, FastAPI, Flask, etc.).

clamp-analytics

Server-side analytics SDK for Clamp Analytics in Python.

Send tracked events from any Python server runtime to Clamp. Works with Django, FastAPI, Flask, Celery workers, scheduled jobs, and anything else that runs Python and can make outbound HTTPS calls.

Install

pip install clamp-analytics

Python 3.9+ supported.

Quick start

from clamp_analytics import init, track, Money

init(project_id="proj_xxx", api_key="sk_proj_xxx")

# Simple event
track("signup", properties={"plan": "pro", "method": "email"})

# Link a server event to a browser visitor (e.g. inside a Stripe webhook)
track(
    "subscription_started",
    anonymous_id="aid_xxx",
    properties={"plan": "pro", "total": Money(29.00, "USD")},
)

Get a server API key at https://clamp.sh/dashboard (Settings → API Keys, format sk_proj_...). Set it as an environment variable; never commit it.

API

init(project_id, api_key, endpoint=None)

Initializes the SDK. Call once at process startup (e.g. in your Django settings.py, FastAPI lifespan, Flask app factory). Stores config in module-level state; subsequent track() calls use it.

endpoint is optional and overrides the default https://api.clamp.sh. Use this for self-hosted Clamp deployments or integration testing.

track(name, properties=None, anonymous_id=None, timestamp=None)

Sends a server event.

• name: event name string. Examples: "signup", "subscription_started", "feature_used".
• properties: optional dict. Values may be str, int, float, bool, or Money. No nested dicts (other than Money) and no arrays.
• anonymous_id: optional string. Links the server event to a browser visitor. Read the browser's anonymous ID via the JS SDK's getAnonymousId() and pass it through your auth flow (e.g. Stripe's client_reference_id).
• timestamp: optional. Pass a datetime (timezone-aware preferred; naive datetimes are assumed UTC) or an ISO 8601 string. If omitted, the SDK uses the current UTC time.

Returns True on success. Raises ClampHTTPError on a non-2xx response or ClampNotInitializedError if init() wasn't called.

Money(amount, currency)

A typed monetary value. Use it for revenue, refunds, taxes; anywhere a currency-denominated amount belongs.

track("purchase", properties={
    "plan": "pro",
    "total": Money(29.00, "USD"),
    "tax": Money(4.35, "USD"),
})

amount is in major units (29.00, not 2900). currency is an ISO 4217 code (uppercase, three letters).

Framework integrations

Per-framework integration patterns (Django middleware, FastAPI dependency, Flask after_request, Celery task hook) are documented at https://clamp.sh/docs/sdk/python.

Errors

The SDK is synchronous and raises on failure. There are no automatic retries. If you want fire-and-forget behavior, wrap the call yourself:

import logging

try:
    track("subscription_started", properties={...})
except Exception:
    logging.exception("failed to send to Clamp")

For high-throughput webhook handlers, consider sending events through a background task queue (Celery, RQ, Dramatiq).
