Kissmetrics

Kissmetrics is a product and behavioral analytics platform that tracks individual people across web and mobile rather than sessions, resolving every event to a persistent identity and surfacing funnels, cohorts, retention, paths, revenue and A/B test reports against that person-level history. Product, marketing and growth teams use it to understand user journeys and pinpoint conversion drop-off, and it now markets an LLM Acquisition report that measures human traffic arriving from AI assistants. Two programmable surfaces are published: a Basic-auth REST Query API at query.kissmetrics.io/v3 for getting data out — account metadata, asynchronous ad-hoc and saved queries, SQL, and CSV/S3 exports — and a query-string tracking beacon at trk.kissmetrics.io for getting events in, alongside first-party Ruby, PHP, Python, iOS and Android libraries and a hosted JavaScript snippet.

Kissmetrics publishes 1 API on the APIs.io network: REST API. Tagged areas include Analytics, Product Analytics, Behavioral Analytics, Marketing Analytics, and Customer Analytics.

Kissmetrics’ developer surface includes authentication, code examples, documentation, API reference, getting-started guide, pricing, signup flow, and 29 more developer resources.

  name: Kissmetrics REST API
  description: 'REST API for programmatic access to Kissmetrics reports, segments, events, properties and account metadata.
    Queries are asynchronous: a POST to /queries, /queries/report or /queries/metric returns a query id which is polled at
    /queries/{id} and cancelled with a DELETE, and results are materialized through /exports to CSV or a customer S3 bucket.
    Nine query types are published, including cohort, funnel, ab_test, people_search and raw sql. Used to pull report data
    into dashboards, spreadsheets and BI tools, and to export user segments to destinations without native integrations. Authentication
    is HTTP Basic in the Authorization header. The API is self-declared beta and rate limited to 15 requests per minute.'

  description: Event ingest surface. Three query-string endpoints record an event (/e), set person properties (/s) and irreversibly
    alias two identities to one person (/a), accepting GET or POST with the product key in `_k`, the person identity in `_p`
    and arbitrary additional keys as person properties. It powers the hosted JavaScript snippet, the first-party Ruby, PHP,
    Python, iOS and Android libraries, and the 1x1 pixel beacon used for email and ad impression tracking. By design it answers
    200 OK with a 1x1 GIF to every request, valid or not, so a 200 is not evidence an event was accepted. This entry replaces
    the former Kissmetrics Data Out API entry, whose only documentation host, oldsupport.kissmetrics.com, no longer resolves
    (probed 2026-08-13).
