Statsig Events API

The Statsig Events API handles the ingestion of event data from both client and server SDKs. It receives exposure events, custom events, and diagnostic data at the events.statsigapi.net endpoint. This data powers Statsig's experimentation analysis, product analytics, and metric computations. The Events API is optimized for high-throughput data ingestion, processing over a trillion events daily with high reliability and low latency, enabling real-time experiment monitoring and metric updates.

Authentication & Security 3

Statsig Events API declares 3 security schemes for authenticating requests. An API key is passed in the header as statsig-api-key (clientSdkKey). An API key is passed in the header as statsig-api-key (statsigApiKey). An API key is passed in the header as statsig-api-key (serverSecretKey).

  • clientSdkKey — Client-SDK Key that is safe to embed in mobile apps and front-end web applications. Created in Project Settings API Keys tab.
  • statsigApiKey — API key for authentication. Use a Server Secret Key for secure server-side requests or a Client-SDK Key for client-side applications.
  • serverSecretKey — Server Secret Key for secure server-side API access. Must only be used from trusted server environments and never exposed client-side.

Where this information came from

This is an independent, third-party profile of Statsig Events API, published by API Evangelist. We do not operate, host, resell, or support these APIs, and we are not affiliated with or endorsed by the company unless stated above. Everything here is built from publicly available information — the company's own site, developer portal, documentation, public repositories, and the specifications it publishes for public use. Nothing is obtained by breaching a system, defeating an access control, or using credentials.

The Kin Score and Agent Readiness rating are independently calculated assessments of a company's public API artifacts, scored against a published rubric. They are not certifications, endorsements, security assessments, or audits.

Corrections, re-scores, and removal are free — no partnership or purchase required, and you do not need to justify the request. A removed company is recorded as unrated, never scored zero for having asked. Acknowledgement within one business day; removal within two.
