Generate Kling 3.0 commercial videos from form prompts with Pollo API

Quick overview

This workflow collects a video prompt and optional image URL via an n8n form, starts a Kling 3.0 generation job through the Pollo API, repeatedly polls for completion, and returns the final task status and generated video URL.

How it works

1. Receives a submission from an n8n form containing a prompt, optional image URL, model path, and Pollo API key.
2. Sends a POST request to the Pollo API generation endpoint for the provided model (for example, kling-ai/kling-v3-0) to start a video generation task.
3. Waits 10 seconds and then requests the task status from the Pollo API using the returned task ID.
4. Repeats the wait-and-status-check loop until the generation status is either succeed or failed.
5. Outputs the task ID, final status, video URL, media type, and remaining credits (with credits set to 0 if the response indicates they were refunded).

Setup

1. Create a Pollo API account and have an API key available to use in the form submission.
2. Set the model_path value you want to call (for Kling 3.0, use kling-ai/kling-v3-0).
3. If you use image_url, ensure it is a publicly accessible direct link to the image.
4. Run the workflow once to get the form URL, then share or embed it wherever you want users to submit prompts.
