Schedule LinkedIn Posts with AI Content Generation and Telegram Approval

Overview This workflow automates LinkedIn posts using OpenAI. The prompts are stored in the workflow and can be customized as needed to fit your needs. The workflow uses a combination of a Schedule Trigger, some code that determines what day of the week it is (no posting Friday - Sunday), a prompts node to set your OpenAI prompts, a random selection of a prompt so that you are not generating content that looks repetitive. We send that all to OpenAI API, select a random time, have the final LinkedIn post sent to your Telegram for approval, once approved wait for the correct time slot, and then Post to your LinkedIn account using the LinkedIn node.

How it works:

Run or schedule the workflow in n8n The automation can be triggered manually or on a custom schedule (excluding weekends if needed).

You should customize the prompts in the Prompt Node to suit your needs.

A random LinkedIn post prompt is selected Pre-written prompts are rotated to keep content fresh and non-repetitive.
