Pavyzdys

Making any POST request is a multi-step process:

Log in, via one of the methods described on API:Login .
GET an edit/CSRF token as shown here API:Tokens
api.php?action=query&format=json&meta=tokens [try in ApiSandbox]
Send a POST request, with the CSRF token, to merge page histories.

The sample codes below cover these steps.
