Automatically generate Linkedin Carousal and Upload to Linkedin

Use case : Linkedin Content Creation, specifically carousal. But could be adjusted for many other creations as well.

How it works

  • It will run automatically every 6:00 AM
  • Get latest News from TechRadar
  • Parse it into readable JSON
  • AI will decide, which news resonates with your profile
  • Then give the title and description of that news to generate the final linkedin carousal content.
  • This step is also trigerred by Form trigger
  • After carousal generation, it will give it to Post Nitro to create images on that content.
  • Post Nitro provides the PDF file.
  • We Upload the PDf file to Linkedin and get the file ID, in next step, it will be used.
  • Finally create the Post description and Post it to Linkedin

How to use

  • It will run every 6:00 AM automatically. Just make it Live
  • Submit the form, with correct title and description ( i did not added tests for that so must give that correct 😅 )

Requirements
