# Frequently asked questions

Quick answers about the Estactics API.

## Do I need to send my organization ID?

No. Your API key already identifies your organization.

## Can I use the API from my website's JavaScript?

The API accepts browser requests, but anyone visiting the page could read your key. Call the API from your server instead.

## Why do read requests use POST?

Search endpoints take filters and field lists, which are easier to send in a body. Check each endpoint in the [API reference](/reference) for its method.

## Does each response tell me the total?

No. Call the matching count endpoint, as described in [Pagination](/docs/pagination).

## Can I test without touching real data?

There is no separate test environment. Create a clearly named test record, and delete it when you finish.

## Where can I get help?
