Veo 3 Video Ad Generator n8n Workflow via Pollo API Form Trigger

Generate Veo 3 video ads from an n8n Form—using the Pollo API (with optional image support)

Turn form submissions into Google Veo 3 video ad generations automatically. This n8n automation workflow collects a prompt (and optional image URL), sends it to the Pollo API Veo 3 generation endpoint, then polls until the job completes and returns the final status and video URL.

What this workflow does

• Receives input via an n8n Form Trigger: collects prompt, model_path (e.g., google/veo3), api_key, and optional image_url.
• Submits a generation request to Pollo API: sends a POST request to the specified Veo 3 generation endpoint, including the prompt and (if provided) an image reference.
• Waits and polls for results: pauses for 10 seconds to let processing start, then repeatedly checks generation status using the returned task ID.
• Returns complete outputs: outputs the task ID, final task status (succeeded/failed), generated video URL, media type, and credit usage information.

Use cases

• Marketing content ops: collect ad ideas from a team form and generate video ad drafts on demand.
• SaaS operators: build a self-serve “video ad generator” request flow backed by Pollo and Veo 3.
• Automation engineers: create a reliable pattern for async generation + polling using n8n and HTTP requests.

Technical details

• Workflow trigger: Form Trigger (public form URL submission)
• Core logic nodes: if, set, wait, sticky note, form trigger, http request
• External API: Pollo API Google Veo 3 generation endpoint (model path like google/veo3)
• Image input requirement: if using image_url, it must be publicly accessible (no login and no expiring access), so Pollo can fetch it.

Ideal for building n8n video ad generation pipelines that turn a prompt into a completed Veo 3 result—fully automated.
