POST request to change the language of a page.
API documentation
Example
Making any POST request is a multi-step process:
- Log in, via one of the methods described on API:Login.
- GET a CSRF token.
- Send a POST request, with the CSRF token, to take action on a page.
The sample code below covers the final step in detail.
