Generate Google Veo 3.1 AI videos from form prompts with Pollo API

Quick overview

This workflow collects a video prompt (and optional reference image URL) via an n8n form, sends a generation request to the Pollo API for Google Veo 3.1, polls the task status until it succeeds, and returns the finished video URL and related metadata.

How it works

1. Receives a form submission containing a prompt, optional image_url, model_path, and Pollo API key from https://api.pollo.ai/api-keys.
2. Sends a POST request to the Pollo API generation endpoint for the selected model (for example, google/veo3-1) with the prompt and optional reference image.
3. Waits 10 seconds and then queries the Pollo API task status endpoint using the returned taskId.
4. Repeats the wait-and-check loop until the generation status is reported as succeed.
5. Outputs a simplified result containing the task ID, status, generated video URL, media type, and credit usage.

Setup

1. Create a Pollo API account and provide a valid API key (x-api-key) in the form submission.
2. Configure the form fields (prompt, image_url, model_path, api_key) and set model_path to the Pollo model route you want to use (for example, google/veo3-1).
3. If using image_url, ensure the referenced image URL is publicly accessible so Pollo can fetch it during generation.
