Your Wiki.js installation exposes a REST API at path /_api. It's fully documented and OpenAPI 3.0 compliant.
Open https://wiki.example.com/_api in your browser to see the list of all available endpoints and their parameters.
In the Administration Area API Access page, click the Enable API button in the top-right corner to allow API tokens to be used.
Note
Disabling the API doesn't turn off the API endpoints. It only prevents API keys from being used.
Warning
Make sure to save the key value in a safe place. It will not be shown again!
Tip
To authenticate your requests, add a X-API-Key header with the key value. e.g.:
X-API-Key: eyJhbGciOi...
