It now supports real time web hooks.

Gosh I sound like a Zapier salesman :)

i don't think it works well. Tried it, not all updates come in especially if you're using lookup formulas.

If they can do Zapier push then a webhook should not be that hard to pull of either. But the request has been there for a long time (https://community.airtable.com/t/webhooks-for-records/1966) and I just don't think that their architecture is ready for it (yet).

Maybe the 50mio will do some good :-)
