Webhook with basic authentication - Error code 419



I use basic authentication for the webhook with email & password. But it returns me error code 419. It means authentication timeout. Every time the webhook is triggered, hubspot will send a new http post request? Why is it timeout?

Error Message:
Webhook failed: Client error
Server responded with error code 419


Welcome, @tiw1.

Happy to help. Could you share a link to your app's Monitoring tab so I can investigate the errors?

The link should look like this: https://app.hubspot.com/developer/{developer-hub-id}/application/{app-id}/monitoring/webhooks.
