Zapier webhooks keeps asking to "reauthorize your user"

Hi everyone!

I’m currently using Zapier’s webhooks to connect with Webflow, the zaps all work correctly, but after every few zaps, I get this error “This token is invalid. Please reauthorize your user”. Then I grab a new API token and the zap works again, but why does this keep happening? Not idea at all obviously. Thank you in advance!
