How to automate posting to websites, social networks?

Question

Automation

There are 2 social networks and 2 sites, it is necessary to fill in about 10 fields for the event: photo, title, description, tags, date, etc. on sites, all 10 fields will be involved, in social. networks are smaller (most often about 3). I would like to somehow automate so that in one program all the data is filled in, and the input fields on sites and social. networks, this data was pulled up when you open a page to create a new event / post / news.
Are there ready-made examples of such solutions? Is it possible to implement this without programming knowledge?
