Linking Zapier Account to ChatGPT4

Hello OpenAI Community

I have a newbie question, as I am trying to connect my zapier account to Chatgpt

From my research using Chagpt4 it gave me two ways to connect the two - the first using the formatting tool on Zapier and an API key from OpenAI and the second method was using a webhook.

Can I can get some advice on which is the most efficient way to get Zapier to communicate with ChatGPT

If Webhooks are the way to go, can I get someone’s insight on where to find the Endpoint URL in the OpenAI’s documentation?

Thanks

API Key would probably be easier? Where do I find my API Key? | OpenAI Help Center
