It has predictable resource-oriented URLs, accepts JSON-encoded request bodies, returns JSON-encoded responses, and uses standard HTTP response codes, authentication, and verbs. ## Where to find your keys 1. Sign in to the Qonversion dashboard at https://dash.qonversion.io/. 2. Open your project and go to **Project Settings** in the sidebar. 3. The **Project Keys** section exposes three values: - **Project Key** - bearer token for the v3 REST endpoints documented here. A 32-character URL-safe random string (`A-Z`, `a-z`, `0-9`, `_`, `-`) with no fixed prefix (e.g. `JFPATc4VaaWYsfurml3qZ4zsmNw0VfWH`). - **API Key** - used in the URL path of the analytics API (`https://api.qonversion.io/v1/analytics/{API_KEY}/...`); do NOT use it as a v3 bearer. - **Secret Key** - bearer for the entitlement grant/revoke endpoints. Always prefixed with `sk_`. ## Sandbox vs production Project Keys with the `test_` prefix (e.g. `test_PV77YHL7qnGvsdmpTs7gimsxUvY-Znl2`) target the **sandbox** environment. Production keys have no prefix. The same prefix scheme applies to Secret Keys. Sandbox users do not affect production analytics. ## Errors All endpoints share the error envelope shown in `Error`. The `meta.reference` URL is set automatically for the documented machine-readable codes (`invalid_data`, `invalid_request`, `invalid_entitlement_data`); other errors omit `meta`. There is no `meta.fields[]` array. servers: - url: https://api.qonversion.io/v3 description: Production security: - ProjectKey: [] paths: /products/{uid}: patch: tags: - Products summary: Patch a product description: > Partially updates a product.
