Discourse API Documentation
This page contains the documentation on how to use Discourse through API calls.
> Note: For any endpoints not listed you can follow the
reverse engineer the Discourse API
guide to figure out how to use an API endpoint.
The Content-Type for POST and PUT requests can be set to application/x-www-form-urlencoded,
multipart/form-data, or application/json.
Endpoint Names and Response Content-Type
Most API endpoints provide the same content as their HTML counterparts. For example
the URL /categories serves a list of categories, the /categories.json API provides the
same information in JSON format.
Instead of sending API requests to /categories.json you may also send them to /categories
and add an Accept: application/json header to the request to get the JSON response.
Sending requests with the Accept header is necessary if you want to use URLs
for related endpoints returned by the API, such as pagination URLs.
These URLs are returned without the .json prefix so you need to add the header in
order to get the correct response format.
Some endpoints do not require any authentication, pretty much anything else will
require you to be authenticated.
To become authenticated you will need to create an API Key from the admin panel.
Once you have your API Key you can pass it in along with your API Username
as an HTTP header like this:
If an endpoint accepts a boolean be sure to specify it as a lowercase
true or false value unless noted otherwise.
