It converts the form values into the JSON payload expected by the Havis API.\n3. It submits the job to `https://havis.ai/api/grok-imagine` and receives a task ID.\n4. It polls `https://havis.ai/api/task/{task_id}` until the job finishes or fails.\n5. It returns the task metadata, credit usage, payload, and generated result URLs.\n\n### Setup steps\n\n- [ ] Create a Havis API key at https://havis.ai/manager/profile.\n- [ ] Open the form trigger URL after importing this workflow into n8n.\n- [ ] Enter the required Grok Imagine inputs: prompt, model, duration, image_url_1, image_url_2, image_url_3.\n- [ ] Confirm your Havis account has enough credits before running the workflow.\n- [ ] Adjust the polling wait time if your executions need faster or slower status checks.\n\n### Customization\n\nChange default prompt values, optional fields, polling interval, or the final output fields to match your automation. Keep the Havis domain fixed unless you intentionally publish a separate private workflow."
