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.
Create-or-Update Ergonomics applies to this provider. This API accepts writes, so it
carries 10 points of the composite. It is scored from the published contracts
themselves: whether a caller can create-or-update in one call, whether the write accepts a key the caller already
holds, and whether the response says which branch ran. Without that, every write needs a search-and-branch in
front of it, and the first time that check is skipped a duplicate record is created.
Scored against the observed mean rather than raw — a provider at the catalog average is unchanged by this facet,
not penalised by it.
Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/kissmetrics: open an issue to ask a question, or submit a pull request to add artifacts.

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).
