## Update a relay

**put** `/accounts/{account_id}/moq/relays/{relay_id}`

Updates a relay's name and/or configuration. Partial updates:
omitted fields are preserved. Config sub-objects replace as
whole objects when present. origin_fallback and lingering_subscribe
are mutually exclusive.

### Path Parameters

- `account_id: string`

  Cloudflare account identifier.

- `relay_id: string`

### Body Parameters

- `config: optional object { lingering_subscribe, origin_fallback }`

  origin_fallback and lingering_subscribe are mutually exclusive.

  - `lingering_subscribe: optional object { enabled, max_timeout_ms }`

    - `enabled: optional boolean`

    - `max_timeout_ms: optional number`

      Relay-level ceiling on lingering subscribe timeout (ms). Default 30000.

  - `origin_fallback: optional object { enabled, origins }`

    - `enabled: optional boolean`

    - `origins: optional array of object { url }`

      Ordered list of upstream origin relays. Each entry is an object
      (not a bare string) so per-origin configuration can be added in
      the future without another breaking change.

      - `url: optional string`

        Upstream origin relay URL.

- `name: optional string`

### Returns
