Hi Zapier Community, I'm experiencing an issue with my Zap where the ChatGPT step fails due to input data errors. I've checked the field names and formatting but the problem persists. Could anyone offer guidance or share similar experiences? Thanks in advance for your help!

I'm trying to connect GoHighLevel with ChatGPT using Zapier to generate funnel copy automatically. However, I'm encountering issues with the ChatGPT step due to input data errors. I've checked the field names and formatting but can't resolve the problem. Any advice or similar experiences would be greatly appreciated. Thank you!

Hi
Thanks for reaching out and sharing the screenshot—it's a common issue with the ChatGPT (OpenAI) Zapier action. The error "Failed to create a conversation" usually means the messages input is missing or incorrectly formatted, or there's a model access issue. Make sure you're sending a properly structured array like [{"role": "user", "content": "Your prompt"}], not just a plain string. Also, double-check that your model (like gpt-4o) is accessible via your OpenAI account. If needed, try switching to gpt-3.5-turbo as a test. Adding a "Code by Zapier" step to structure the message before the ChatGPT action often resolves this. Finally, confirm that the Webhook passes actual data into the message field.
