inbound_unavailable

Inbound event could not be stored · HTTP 503

What causes this

The event verified but could not be written to the store or enqueued for delivery. This is transient — it is our side, not the sender's.

How to fix it

Retry with the same Idempotency-Key. The event is deduplicated on that key, so a repeat after a partial failure is safe.
