Hello, fellow flowgrammers,
I built this exciting n8n automation that will design the post for you and upload the carousel to Instagram after your approval. No, it does not use AI. You have to give the script manually.
Here is the resultant carousel: https://www.instagram.com/p/DPtdBZHjDmd/?img_index=1
How it works?
Well, I made a full youtube tutorial if you are interested: https://www.youtube.com/watch?v=TKyjkgluTCA
Here is the flow:
1. The form node accepts the text input, deletes the rows in google sheet (you will understand the reason once you work with the workflow ) and loops through each input
2. It uses apitemplate.io to automate image generation with api and parameters with custom predesigned template
3. The urls/links of hosted images will be stored in the google sheet as the loop iterates
4. After the end of the loop, All the links will be retrieved from google sheet and a html email template will be generated showcasing all the images
5. Human in the loop - Manual approval email will be sent in Gmail
6. If approved, The carousel will be uploaded to Instagram using http requests of Blotato
If you don’t want to take a headache of designing Instagram posts every single time, maybe just build this flow once and enjoy.
A like helps
