# Get Data Schema Event Volume

`GET /v2/charts/data-schema/event-volume`

## Request

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

How often each of an app's events arrived in production, per day, over the last 30 days (UTC, today included), with each event's total: the counts behind Get Data Schema's event lists. Counts are approximate (about 1.6% error), and an event delivered twice counts once. Read from a daily rollup, so it answers in about a second for any app. Requires charts:read scope.

## Query parameters

- `application_id` string, required

## Response `200`

Success

- object
  - `object` 'data_schema_event_volume', required: Object type, always `data_schema_event_volume`
  - `days` string[], required: The window's dates (UTC, `YYYY-MM-DD`), oldest first: the last 30 days, today included
  - `events` object[], required: Every event that arrived in the window, most arrivals first. An event Get Data Schema lists but that isn't here didn't arrive in the window.
    - `name` string, required: The event's name, as Get Data Schema lists it
    - `total` number, required: How many times the event arrived over the window
    - `daily` number[], required: Arrivals per day, one entry per date in `days`, oldest first (30 entries; 0 for a day with none)
