How are you running Sentry?
Saas (sentry.io)
When I trying to save webhook configuration with callback URL ex. https://fb0e7c33c1d6.ngrok.io/sentry or https://webhook.site/afd3cc94-d436-4293-8c19-4a91c0d6d0f4 validation error occurs - Not a valid URL.
https://fb0e7c33c1d6.ngrok.io/sentry to Callback URLs textareaGood items to include here include:

No errors
Fix validation for callback URL
I have the exact same issue with another URL:
https://app.datadoghq.com/intake/webhook/sentry?api_key=MY_DATADOG_API_KEY (needless to say I do provide my actual API key in the URL)
I experienced the same issue with Datadog EU URL:
https://app.datadoghq.eu/intake/webhook/sentry?api_key=MY_DATADOG_API_KEY
https://sentry.io/api/0/projects/ORGANIZATION/PROJECT/plugins/webhooks/ responds with 400 Bad Request.
