n8n AI Image/Video Generator Workflow with Webhook & Form

Generate AI images or videos from an n8n prompt—via Webhook or Form—and get results back as JSON

This n8n AI Image/Video Generator Workflow takes a prompt, modelId, and aspectRatio, starts generation on imgmov.com, polls until it’s complete, and returns the final result URLs (or an error) as a JSON webhook response.

What this workflow does

• Receives inputs from an n8n form submission or an incoming webhook request.
• Applies defaults when any values are missing (for prompt, model ID, and aspect ratio).
• Starts an imgmov generation task by calling imgmov API POST /generate and capturing the returned task ID.
• Waits and polls: pauses for 10 seconds, then checks status using imgmov API GET /tasks/:taskId.
• Repeats until completion, then formats completed task details—including result URLs and credits cost.
• Returns JSON with either the results or an error if the task status is failed.

Use cases

• SaaS operator building a “Generate Media” button that triggers imgmov from an n8n webhook and immediately returns result links.
• Automation engineers integrating AI image/video generation into existing pipelines (e.g., store URLs, notify users, or update a dashboard).
• Teams testing prompts using the n8n Form trigger to quickly iterate with different modelId and aspectRatio values.

Technical details

• Trigger options: n8n Form trigger or Webhook.
• Nodes used: if, set, wait, webhook, sticky note, form trigger.
• imgmov API integration: POST /generate to create tasks; GET /tasks/:taskId to poll status.
• Authentication: create an imgmov API key and configure an n8n HTTP Header Auth credential as Authorization: Bearer <YOUR_API_KEY>.
