# Create a relay

POST/accounts/{account\_id}/moq/relays

Provisions a new MoQ relay instance. Auto-creates a publish+subscribe token and a subscribe-only token. Token values are included in the response (shown once). Config is always set to defaults (upstreams off) and cannot be supplied here — sending a non-empty `config` is rejected (21014); `null` or `{}` is accepted as absent. Use PUT to configure the relay after it exists.

##### Security

API Token

The preferred authorization scheme for interacting with the Cloudflare API. [Create a token](https://developers.cloudflare.com/fundamentals/api/get-started/create-token/).

**Example:**`Authorization: Bearer Sn3lZJTBX6kkg7OdcBUAxOO963GEIyGQqnFTOFYY`

##### Path ParametersExpand Collapse 

account\_id: string

Cloudflare account identifier.

##### Body ParametersJSONExpand Collapse 

name: string

Human-readable name for the relay.

minLength1

##### ReturnsExpand Collapse 

errors: array of object { code, message } 

code: optional number

message: optional string

messages: array of object { code, message } 

code: optional number

message: optional string

success: boolean

result: optional object { config, created, issuers, 3 more } 

Relay with its auto-created default token pair (one full-access \[publish, subscribe\] and one \[subscribe\]-only), each with its one-time secret, wrapped in the issuers envelope.

config: object { upstreams } 

upstreams: optional object { enabled, upstreams } 

Upstreams are external MOQT server publishers that a relay falls back to when it has no local publisher for a requested namespace/track.

enabled: optional boolean

upstreams: optional array of object { url } 

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

url: string

Upstream MOQT server publisher URL. Must be an absolute URL with a host and a scheme the relay can dial: moqt:// (raw QUIC) or https:// (WebTransport). Validated on update (PUT); rejected with 21013.

formaturi

created: string

formatdate-time

issuers: array of object { cloudflare\_tokens, issuer, type } 

Token collection (discriminated union on `type`). On create this holds the auto-created default pair, each including its one-time secret.

cloudflare\_tokens: array of object { created, expires, jti, 3 more } 

Always present (\[\] when empty).

created: string

formatdate-time

expires: string

Mandatory; no more than 1 year after `created`.

formatdate-time

jti: string

Token identity and registry key (32 hex chars).

operations: array of "publish" or "subscribe"

Signed allowlist of what the token may do. V1 coarse roles; the array form extends to fine-grained MoQT message names later without a breaking change.

One of the following:

"publish"

"subscribe"

label: optional string

Optional, customer-set.

secret: optional string

The signed JWT. Present ONLY in create / auto-create responses (shown once); never returned by list, never stored.

issuer: "cloudflare"

type: "cloudflare\_jwt"

modified: string

formatdate-time

name: string

uid: string

Server-generated unique identifier (32 hex chars).
