# Cluster Peering - HTTP API |
|
|
|
The functionality described here is available only in |
|
[Consul](https://www.hashicorp.com/products/consul/) version 1.13.0 and later. |
|
|
|
## Generate a Peering Token |
|
|
|
This endpoint generates a peering token. |
|
|
|
| Method | Path | Produces | |
|
| ------- | -------------------- | ------------------ | |
|
| `POST` | `/peering/token` | `application/json` | |
|
|
|
The table below shows this endpoint's support for |
|
[blocking queries](/consul/api-docs/features/blocking), |
|
[consistency modes](/consul/api-docs/features/consistency), |
|
[agent caching](/consul/api-docs/features/caching), and |
|
[required ACLs](/consul/api-docs/api-structure#authentication). |
|
|
|
| Blocking Queries | Consistency Modes | Agent Caching | ACL Required | |
|

|
|
|
### JSON Request Body Schema |
|
|
|
- `PeerName` `(string: <required>)` - The name assigned to the peer cluster. |
|
The `PeerName` is used to reference the peer cluster in service discovery queries |
|
and configuration entries such as `service-intentions`. This field must be a |
|
valid DNS hostname label. |
|
|
|
- `Partition` `(string: "")` - <EnterpriseAlert inline /> The admin partition that the |
|
peering token is generated from. Uses `default` when not specified. |
|
|
|
- `ServerExternalAddresses` `([]string: <optional>)` - The addresses for the cluster that generates the peering token. Addresses take the form `{host or IP}:port`. |
|
You can specify one or more load balancers or external IPs that route external traffic to this cluster's Consul servers. |
|
|
|
- `Meta` `(map<string|string>: <optional>)` - Specifies KV metadata to associate with |
|
the peering. This parameter is not required and does not directly impact the cluster |
|
peering process. |
|
|
|
### Sample Payload |
|
|
|
```json |
|
{ |
|
"PeerName": "cluster-02", |

## Delete a Peering Connection |
|
|
|
Call this endpoint to delete a peering connection. Consul deletes all data imported from the peer in the background. The peering connection is removed after all associated data has been deleted. |

Operators can still read the peering connections while the data is being removed. A `DeletedAt` |
|
field will be populated with the timestamp of when the peering was marked for deletion. |
|
