n8n Workflow: Generate Veo 3.1 Videos via Pollo API

Generate Veo 3.1 videos from a prompt (and optional images) directly from an n8n form—then deliver the final video URL automatically

This n8n automation workflow submits a video generation request to the Pollo API (Veo 3.1 endpoint), polls until the job finishes, and returns the generated video URL plus status and metadata—all driven by an n8n Form Trigger.

What this workflow does

• Collects input via an n8n form: receives a prompt, optional image_url(s), the Pollo model path (e.g., google/veo3-1), and a Pollo API key.
• Starts a Veo 3.1 generation task: sends a POST request to the Pollo API using the provided prompt and optional image guidance.
• Polls job status until completion: waits 10 seconds, then repeatedly checks the task status using the returned task ID.
• Stops on success or failure: the loop continues until Pollo reports succeed or failed.
• Outputs results: returns the task ID, final status, generated video URL, media type, and the reported credit value.

Use cases

• Enable non-technical teams to request Veo 3.1 video generation using a simple n8n form.
• Build a controlled “prompt-to-video” service for SaaS operations with automated status tracking.
• Create image-guided video generation by supplying publicly accessible image URLs for Pollo to fetch during generation.

Technical details

• Nodes / components: Form Trigger, HTTP Request, Wait, If, Set, Sticky Note.
• Integrations: Pollo API with the Veo 3.1 model path (e.g., google/veo3-1).
• Operational behavior: POST to start generation, then wait-and-check loop polling by task ID.

Setup note: ensure any submitted image_url values are publicly accessible so Pollo can retrieve them during generation.
