Webhook request to check availability

I have a business where we rent home alarm systems.
We use Airtable to manage the stock and availability of the kits.
I would like to introduce it in our booking form, so what I want to do is make a request to check if in the dates my client wants to rent the alarm system, we have some system available.
Di you know if this is possible and can help me a little please?

Thanks community!

What you can do is filter your availability dates to be based on your inventory. So that only valid dates are shown on your booking form. You can display those linked records as a calendar using our Advanced Form for Airtable.
