I am new to the media wiki. Any help on this below query is highly appreciated.

Query:

I have created a media wiki server and update a section of one particular page (a table of values) dynamically.

I am planning to do this using rest APIs referring to https://www.mediawiki.org/wiki/API:Tutorial 

What is the flow I should follow to edit a page? Should I use APIs to login first and then get the csrf token using another rest API and then finally update the page.

What is the exact sequence??

Thanks in advance
