webhook timing

Hi,

We are using the hook web integration to send the user reg data back to our backend. After the typeform submission, we redirect to our landing page, which does a look up in our database on the user reg data to perform further action. My question - is it guaranteed that the web hook submission happen BEFORE the redirect? We are seeing a weird rare issue when we get to the redirect landing page, the data is not there yet - but later when we go back to the same landing page, the data then appears. Thanks for your help.

Thanks,
Bryan
