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 for its method.
Does each response tell me the total?
No. Call the matching count endpoint, as described in 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.
