In plain English
Other software can read and write WordPress content over HTTP: fetch posts, create entries, update fields. The block editor itself uses it.
It also enables headless WordPress, where WordPress stores and manages content and a separate front end presents it.
What to know
HTTP endpoints
Read and write content.
Used by the editor
Not an optional extra.
Enables headless setups
Content managed here, presented elsewhere.
Needs authentication
For anything beyond public reads.
Why it matters
For integrations, the REST API means WordPress content can feed apps, dashboards and other systems without manual export. For most business sites it works quietly in the background.
Common mistakes
×Disabling it entirely, which breaks the editor.
×Exposing endpoints that reveal user information.
×No authentication on write operations.
×Choosing headless without the development capacity to maintain it.
FAQs
Should I disable the REST API?
No. The editor depends on it. Restrict specific endpoints if needed.
What is headless WordPress?
WordPress as the content store, with a separate front end consuming the API.
