# Get Data Schema Property Index

`GET /v2/charts/data-schema/property-index`

## Request

- Base URL: `https://api.superwall.com`
- URL: `https://api.superwall.com/v2/charts/data-schema/property-index`
- Auth: one of:
  - HTTP bearer
  - API key in cookie `accounts_superwall_token`
  - HTTP bearer

Lists the property keys of every event Get Data Schema lists, in one response, with every JSON type each arrived as: what you need to search property keys across events. Each event holds its 500 most recently seen keys, without last-seen times; `properties_truncated` says when an event was cut. The SDK's bookkeeping keys are left out. Read from pre-aggregated data. Requires charts:read scope.

## Query parameters

- `application_id` string, required

## Response `200`

Success

- object
  - `object` 'data_schema_property_index', required: Object type, always `data_schema_property_index`
  - `events` object[], required: The events Get Data Schema lists, custom and standard, each with its property keys. Events with no properties are left out.
    - `name` string, required: The event's name, as Get Data Schema lists it
    - `properties` object[], required: The event's property keys, sorted by key: at most 500, the most recently seen.
      - `key` string, required: The property's key, as the app sent it
      - `types` string[], required: Every JSON type the key has arrived as, most recently seen first. More than one means the app has sent the key with different types.
  - `properties_truncated` boolean, required: True when at least one event has carried more than 500 property keys, so its list holds only the most recently seen.
