The feature will put the workflow in a waiting state where a message is sent to the admin with 2 buttons: confirm and decline.\n\nWhen the admin clicks on the confirm button, the workflow resumes from the Gmail node and a meeting event is created for the requesting user in Google Calendar.\n\nWhen declined, a rejection email is sent to the requester instead."

It also uses n8n's wait for approval feature which allows the ability to confirm appointment requests and create events in Google Calendar.\n\n### How it works\n* We start with a form trigger which asks for the purpose of the appointment.\n* Instantly, we can qualify this by using a text classifier node which uses AI's contextual understanding to ensure the appointment is worthwhile. If not, an alternative is suggested instead.\n* Multi-page forms are then used to set the terms of the appointment and ask the user for a desired date and time.\n* An acknowledgement is sent to the user while an approval by email process is triggered in the background.\n* In a subworkflow, we use Gmail with the wait for approval operation to send an approval form to the admin user who can either confirm or decline the appointment request.\n* When approved, a Google Calendar event is created. When declined, the user is notified via email that the appointment request was declined.\n\n### Need Help?\nJoin the [Discord](https://discord.com/invite/XPKeKXeB7d) or ask in the [Forum](https://community.n8n.io/)!\n\nHappy Hacking!\n"
