Is it possible to automate the addition of news content without parsers?

Question

CMS

There are 20 sites on WordPress, you need to add articles (news) with tags, with photos in the materials, with the necessary headings, and so on. You also need to change prices - but the store is on the constructor, everything is done manually.
There are 2 sites on Bitrix - the same. It is necessary to add materials (more often news)
Are there programs somehow or MB plugins?

Answer 1

XML-RPC
In WP, it's built in by default.
In Bitrix - I do not know.
