Create metaphor-driven video ads with Google Veo 3 via Pollo API

Description

Quick overview
This workflow collects a video-ad prompt via an n8n form and submits it to Pollo API’s Google Veo 3 generation endpoint (optionally with an image reference), then polls Pollo for completion and returns the final task status and video URL.

How it works
Receives a submission from an n8n form containing a prompt, optional image URL, Veo 3 model path, and a Pollo API key.
Sends a POST request to Pollo API’s generation endpoint for the specified model (for example, google/veo3), passing the prompt and optional image reference.
Waits 10 seconds to give Pollo time to start processing the generation task.
Requests the generation status from Pollo API using the returned task ID.
Repeats the wait-and-check cycle until Pollo reports the generation as succeeded or failed.
Outputs the task ID, final status, generated video URL, media type, and credit usage information.

Setup
Create a Pollo API account and generate an API key with access to the Veo 3 endpoint.
Publish the n8n form and use its URL to submit the required fields (prompt, model_path like google/veo3, and api_key) and optional image_url.
If you use image_url, ensure the image link is publicly accessible (no login or expiring URL) so Pollo can fetch it.
