# GET /gammas/{gammaId}/analytics

Retrieve doc-level engagement metrics for a single Gamma.

## Get Gamma analytics

> Returns doc-level engagement metrics for a Gamma: total views, unique viewers/editors, card count, last opened time, and a 30-day daily unique-viewer breakdown. Requires at least edit permission on the Gamma. When the API key's user has manage permission the metrics cover all viewers (\`scope: "all"\`); otherwise they cover only that user's own activity (\`scope: "self"\`). Data is eventually consistent (\~hourly).

{% hint style="info" %}
Accepts either the API file ID or the doc ID from a `gamma.app/docs/...` URL. Requires at least edit permission on the Gamma. The response `scope` field is `all` when the API key owner has manage permission (metrics cover every viewer) or `self` when they have edit permission only (metrics cover that user's activity). Metrics are eventually consistent and update about hourly.
{% endhint %}

This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://developers.gamma.app/analytics/get-gamma-analytics.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
