# webhook_unavailable

> The test event was published, but the webhook pipeline could not store or queue it, so your endpoints will not receive it.

Source: https://tickwire.io/docs/errors/webhook_unavailable/

HTTP 503.

**Likely cause:** POST /v1/webhook-events/trigger while webhook storage or the delivery queue is failing.

**What to do:** Retry later with a new Idempotency-Key. Running tickwire listen sessions still received the event. If it persists, check the status page and contact support with the requestId.

**Retry:** Yes. Nothing happened (or it was a read), so repeat it, after `Retry-After` when present.
