Kling 3.0 Text & Image Video Generator (Pollo API) n8n Workflow

Generate Kling 3.0 videos from prompts (and optional images) with the Pollo API—automated in n8n

This n8n workflow lets visitors submit a prompt (and an optional image URL) through an n8n form, then automatically requests a Kling 3.0 text-to-video or image-to-video job via the Pollo API. It polls until the task finishes and returns the final video URL.

What this workflow does

• Receives inputs from an n8n form trigger: prompt, optional image URL, a model path (e.g., kling-ai/kling-v3), and a Pollo API key.
• Chooses the generation mode automatically:
  • If no image URL is provided, it submits a text-to-video request.
  • If an image URL is provided, it submits an image-to-video request.
• Creates a generation task by sending a POST request to the Pollo API using the specified model path.
• Polls for completion: waits 10 seconds, checks the current status using the returned task ID, and repeats until the status is succeed or failed.
• Returns results including task ID, status, media type, credit value, and the generated video URL when available.

Use cases

• Build a simple video generation request form inside your product or internal tool using n8n.
• Enable prompt-driven marketing video drafts that support both pure text prompts and image-based concepts.
• Give SaaS users a guided workflow to generate Kling 3.0 outputs while abstracting Pollo API polling and status tracking.

Technical details

• Nodes / logic: form trigger, if, set, wait, sticky note, http request.
• Pollo API integration: POST to start generation; repeated status checks by task ID.
• Requirements: for image-to-video, the image_url must be publicly accessible so Pollo can fetch it.
• Setup: create a Pollo API account, generate an API key, and provide the correct model path in the form trigger.
