In which social networks can I publish a post from the site?

Question

Web development

We plan to make a site on 1C-Bitrix (if it is important). It is required to make it possible to create a post from one complex form in as many of the following places as possible (optional in checkboxes):

The site itself (that's why it is necessary that the form be on the site, and not on an external resource)

• News
  
• Forum
  

Social network

• facebook
  
• Instagram
  
• whatsapp
  
• Telegram
  
• In contact with
  

Video hosting

• Youtube

I want to know which social networks and video hosting sites can be integrated with this? I would also be grateful for the tips.
