It's Easy..
First Thing to Note Free Makedotcom account comes with 1000 Operations Limit So If planning to do Bulk Posting in Many Social Media accounts Multiple times a day then Free account won't work.
Second:- You need API Level access to any of the Well Known AI Platform ,OpenAI with API Credits if Want Both Text & Image Posting or Perplexity If Ok with Only Text Generation. Claude won't work cause It can't access web for scraping the articles & making summary of it.
First Node RSS Node ,it will ask for RSS Link in Settings. Paste the rss link,modify few basic settings (Done)
Second Node-OpenAI or Perplexity ,Paste your API Key ,Connect, Then Paste the Article Summary Prompt in message then Access Level(User)
Third Node-Router
From Third Node(Router) ,Now you need to create Number of Nodes based on How many social media accounts you have.
For Example: I just wanna create Facebook Post Through it.
Then what you to do is Again Create OPENAI or Perplexity App Node to Router Node,Open Settings,Paste Facebook Post Creation Prompt from Article which we created in 2nd node.
Last Node would be Facebook App Connect,It will ask for Facebook Permission & Allow it
