Create AI video reels from images with GPT Image 2, Seedance and Blotato

Description

Quick Overview
This workflow receives a webhook with an image-edit prompt, a video-motion prompt, and a caption, generates a stylized image with AtlasCloud (OpenAI GPT Image 2) and a vertical video with AtlasCloud (ByteDance Seedance 2.0), then publishes the result to Facebook, TikTok, and Instagram via Blotato.

How it works
Receives a POST webhook request containing prompt, prompt_video, and an optional caption.
Sends the prompt and a configured source image URL to AtlasCloud’s OpenAI GPT Image 2 edit endpoint to generate a new image.
Polls AtlasCloud until the image job completes (or stops with an error on failure) and extracts the generated image URL.
Sends the generated image URL and motion prompt to AtlasCloud’s ByteDance Seedance 2.0 image-to-video endpoint to render a 9:16 video.
Polls AtlasCloud until the video job completes (or stops with an error on failure) and extracts the generated video URL.
Publishes the generated media and caption to TikTok and Instagram via Blotato, and posts the generated image to a configured Facebook page via Blotato.

Setup
Add your AtlasCloud API key by replacing the Authorization: Bearer YOUR_API_HERE header value in all AtlasCloud HTTP requests.
Set the source profile_image_url (the input image URL) and provide your target Blotato account IDs (Facebook page/account, TikTok, and Instagram) in the configuration values.
Connect your Blotato API credentials and ensure your Blotato account is linked to the Facebook Page, TikTok account, and Instagram account you want to publish to.
Copy the webhook URL from n8n and configure your calling app to POST prompt, prompt_video, and caption to it.
