Returns the scroll-depth distribution for the site over a time window. Each row reports the scroll depth (in pixels) that a share of page views reached, at fixed breakpoints of 75%, 50%, and 25% of page views.

Filter the report with top-level query parameters (country, deviceType, pagePath, etc.) or via the filter parameter for multi-value and negation matching. Omit deviceType to include all devices.

Analyze add-on required

This endpoint requires a workspace with the Analyze add-on.

Concurrency limit: 1 request at a time

Each access token can have one Analyze request in flight at a time, across all Analyze endpoints. Additional concurrent requests return 429 Too Many Requests. Wait for your in-flight request to finish, or for the Retry-After interval, then retry.

Required scope | sites:read

Authentication

AuthorizationBearer

Bearer authentication of the form Bearer <token>, where token is your auth token.

Path parameters

site_idstringRequiredformat: "objectid"

Unique identifier for a Site

Query parameters

startTimestringRequiredformat: "date-time"

Inclusive start of the reporting window. Must be a UTC timestamp in ISO 8601 / RFC 3339 format ending in Z (for example, 2026-04-01T00:00:00Z); numeric offsets such as -04:00 or +00:00 are not accepted. Must be on or after 2025-04-09T00:00:00Z.

endTimestringRequiredformat: "date-time"

Exclusive end of the reporting window. Must be a UTC timestamp in ISO 8601 / RFC 3339 format ending in Z (for example, 2026-04-08T00:00:00Z); numeric offsets such as -04:00 or +00:00 are not accepted. Must be greater than startTime and within 100 days of it.

deviceTypeenumOptional

Restrict the report to a single device type.

Allowed values:

countrystringOptional=2 characters

Restrict the report to a single country. ISO 3166-1 alpha-2 (two letters, normalized to uppercase).

pagePathstringOptional

Restrict the report to a single page path.

trafficSourcestringOptional

Restrict the report to a single traffic source code (for example, SO for Organic Search).

referrerstringOptional

Restrict the report to a single referrer domain.

browserstringOptional

Restrict the report to a single browser.

utmCampaignstringOptional

Restrict the report to a single utm_campaign value.

utmMediumstringOptional

Restrict the report to a single utm_medium value.

utmSourcestringOptional

Restrict the report to a single utm_source value.

filterobjectOptional

Filter the report by dimension. Use bracket notation. Scalars take a single value (filter[country][eq]=US, filter[country][ne]=US). Arrays use indexed brackets (filter[country][in][0]=US&filter[country][in][1]=CA, filter[country][nin][0]=US&filter[country][nin][1]=CA). Each dimension entry takes at least one of eq, in, ne, or nin. Filter a given dimension in one place — either a top-level query parameter or a filter entry. See the ScrollDepthFilter schema for the full list of supported dimensions.

Response

Scroll-depth distribution for the requested window and filters.

reportenum

Discriminator identifying the report type.

Allowed values:

windowobject

A reporting time window. endTime must be greater than startTime.

datalist of objects

Scroll-depth breakpoints sorted from shallowest (highest share) to deepest (lowest share). The report currently returns up to three rows, for the 75%, 50%, and 25% breakpoints. Rows may be omitted when the underlying data is sparse.

filterobjectOptional

Filter the scroll depth report by dimension. Each property is an optional set of AnalyzeFilterOperators (eq, in, ne, nin) applied to the named dimension. Filter a given dimension in one place — either inside filter or as a top-level query parameter.
