### What is this page ?

API = Application Programming Interface.
This is the way other applications can communicate with Piwigo. This feature is also know as Web Services.

Examples:

- Wordpress (web blog software) can display random photos from a Piwigo gallery in its sidebar
- Lightroom (photo management software for desktop) can create albums and upload photos to Piwigo

This page lists all API methods available on your Piwigo installation, part of the Piwigo core or added by third-party plugins. For each method you can consult required and optional parameters, and even test them in direct live!

Introduced in Piwigo 16, you can now use an API key in the HTTP header to perform authenticated requests without a user session. For more details, check out our documentation.

For more information you can consult our Wiki Piwigo Web API and our forums.
