As @ScottWorld has suggested, you are free to mimic webhooks by writing them in Javascript as script actions. But unlike true webhook support, the burden is on you to not only build every aspect of the hooking process, but to also utilize a triggering action and lastly - ensure that the number of actions doesn’t exceed the arbitrary quotas established for your account.
That’s a lot of responsibility that vendors try to shield users from by providing true webhook features that everyday users can tap into without these complexities. Until a fully-baked event model and webhook layer is added, this is the state of webhookery in Airtable.
