This template starts when your website chat widget POSTs a message to a Latenode webhook. ChatGPT reads the intent.
JavaScript calls Microsoft Graph to list free slots on the Outlook calendar and to create an event when the visitor picks a time. Put the Graph token in that JavaScript node. ChatGPT is a Latenode AI step. Copy the webhook URL into the chat widget and return the reply on the webhook.
Latenode bills workflow runtime in CPU seconds. The first 10,000 CPU seconds are free each month, then usage follows pay-as-you-go CPU-second pricing. Plug-and-Play (PnP) AI nodes are billed separately—each PnP token is $1 USD, charged pay-as-you-go at vendor cost plus a small processing fee, with no API keys required.
