Koala Collection API

openapi: 3.2.0

  title: Koala Accounts Collection API
  description: 'Koala''s developer-facing HTTP surface for its B2B buyer-intent and go-to-market platform. It has two distinct halves with two distinct auth models:


    1. The **Collection / Batch API** on `https://api2.getkoala.com`, which ingests visitor identifies, custom events, traits, and account-level data. It is authenticated by the workspace **public (publishable) project key** embedded directly in the URL path (`/web/projects/{public_api_key}/...`). There is no bearer token; the key is not secret and the same key powers the browser pixel. A `GET` on the project root returns the JSON bootstrap config the client-side SDK uses to initialize.


    2. The **Deletion (GDPR) API** on `https://app.getkoala.com/api/v1`, which is authenticated with a **secret API key** (`sk_...`) via an `Authorization: Bearer` header and is used to request and poll right-to-erasure deletions.


    Visitor de-anonymization (IP-to-company), person enrichment, and company firmographic enrichment are performed by Koala internally (powered by Clearbit Reveal/Enrich and ZoomInfo) and surfaced in the app, exports, webhooks, and reverse ETL integrations. Koala does not document a public REST endpoint to query enriched company/visitor/intent records directly; that data is consumed through the app, warehouse syncs (BigQuery, Snowflake, Hightouch, Census), and outbound automations.'

      summary: Ingest visitor identifies, events, and traits
      description: Sends a batch of visitor-level data to Koala. The request body MUST include a top-level `profile_id` (from the `ko_id` cookie) or `email` so the payload can be attached to a visitor. Each of `events` and `identifies` is limited to 30 entries per request, and every event in a single request must belong to the same person. A `User-Agent` header is required or the request may be dropped as bot traffic. Authenticated by the public project key in the path.
