endpoint_disabled

This code is registered so the envelope contract and its docs_url anchor stay stable, but no route currently emits it — a disabled endpoint simply stops receiving deliveries, and the affected events are recorded as permanently failed with an “Endpoint inactive” reason. Do not write receiver logic that waits for this response. An endpoint gets disabled in two ways:

• Automatically, and only after five consecutive permanently failed deliveries. disabledReason is free-form prose carrying the streak threshold, today "repeated_failures (>= 5 consecutive deliveries)"; the threshold is interpolated from the retry schedule, so match the repeated_failures prefix rather than the full string. A failed DNS/SSRF re-check counts as one failed attempt feeding that streak — it is not a disable trigger of its own.
• Manually, from the dashboard or PATCH /v1/webhook-endpoints/{id} with isActive: false.

To recover: fix your receiver (it must answer 2xx within 10 seconds), then re-enable the endpoint via PATCH /v1/webhook-endpoints/{endpointId} with isActive: true or from the dashboard. See Webhooks § Delivery and retries.
