Send test webhook

Send a test webhook to verify your endpoint is configured correctly. The test payload includes event: "webhook.test" to distinguish it from real events.

webhook.test belongs to the webhooks resource group, so a key with that group disabled is rejected with 403, as is a test fire on a subscription that lists webhooks in its own disabledResourceGroups (a 403, not a reported delivery failure). Replays of real events (redelivery, dead-letter requeue) run the same checks as live delivery, against both the key's groups and the subscription's.
