Workflow fit
Best when you want the same researched process to run consistently without rebuilding the node chain for every job.
Key features
- 11 connected n8n nodes with one clear form-to-image path
- Collects the prompt and aspect ratio in a publishable n8n form
- Creates a Replicate prediction with Google Imagen 3
- Waits before polling instead of hammering the prediction endpoint
- Routes succeeded, failed and incomplete jobs to separate outcomes
- Returns the generated image URL or a readable error message
Setup instructions
1. Import the workflow JSON into n8n.
2. Create an n8n HTTP Header Auth credential with your Replicate API token and attach it to Create image prediction and Get prediction status.
3. Open Create image prediction and confirm the configured model/version is available in your Replicate account. Replace it if Replicate has retired that version.
4. Publish the form and submit a short prompt with the default aspect ratio.
5. Inspect the prediction ID, wait step and status response. Increase the wait only when the selected model consistently needs longer.
6. Confirm that completed jobs return an image URL and failed jobs expose the provider error.
7. Review the image for rights, likeness, brand and platform requirements. This workflow does not add disclosure metadata automatically.
