Used some of the newer Cloud features (event webhooks, deployment triggers) to kick off flow runs in response to kafka messages. https://medium.com/the-prefect-blog/beyond-scheduling-event-driven-flows-with-prefect-b072edd06833

hi will, can i check is it possible for it to call deployment run from webhook without the need of automation. or the only way is using rest function?

you’ll need to link the webhook request to the deployment with an automation.

is it possible to bypass automation due to the limit

it is not possible via prefect, but if you control the webhook you could potentially hit the /flow_runs endpoint directly rather than a webhook with the appropriate auth/payload to kick off a flow run.
