This comprehensive n8n workflow automates the process of generating, creating, and posting engaging Instagram content based on pre-defined topics stored in Google Sheets. The workflow begins with a scheduled trigger, which fetches the next post idea marked as ‘pending’. It then uses AI-powered language models, like Google Gemini, to generate a compelling content concept, detailed image prompts, and a fitting caption for the post.

Next, the workflow utilizes AI image generation via the Replicate Flux model to produce a high-quality visual aligned with the concept. The generated image URL and caption are then prepared for Instagram API integration, where the media container is created, and after processing time, the content is published directly to the connected Instagram account.

Finally, the workflow updates the Google Sheet to mark the post idea as completed, ensuring smooth, repeatable content automation. This process is ideal for social media managers or marketing teams seeking to streamline content production, maintain consistent posting schedules, and leverage AI to generate creative and engaging visuals and captions effortlessly.
