# Retrieve user properties

> Retrieves all properties for a given user. Up to 100 properties per user.

**Rate limit:** Properties endpoints are rate-limited per project (default 30 requests
per second; configurable on the server). Exceeding the limit returns 429.


<Note>Qonversion-defined properties are prefixed with `_q_` (e.g. `_q_email`). Custom properties use your own keys.</Note>


## OpenAPI

````yaml /api-reference/rest-api.yaml get /users/{id}/properties
openapi: 3.1.0
info:
  title: Qonversion REST API
  version: '3.1'
  description: >
    Qonversion REST API follows REST standards. 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.
