Is necessary to have at least the Standard plan to use this route. The same account may attach one domain to multiple applications (load balancing): up to 2 applications on Standard, 5 on Pro, and 10 on Enterprise. See List Load Balancers.

string

required

The API key for your account. You can find this in your account settings.

Requires an API key with the apps:write scope. Replacing an existing custom domain releases the previous hostname at the edge before attaching the new one, unless another application on the same account still points at it. The same validation runs whether attaching or removing (custom: "@"): on a workspace-shared application, the caller needs the workspace admin role or ownership. A domain can only be claimed by one account at a time: attaching a hostname already held by another account returns DOMAIN_ALREADY_EXISTS. To see every hostname configured across your applications, see List Domains. Once attached, fetch the required validation records with Get DNS Records.

Parameters

string

required

The ID of the application. You can find this in the URL of your application’s dashboard.

string

required

The fully qualified domain to attach, or @ to remove the application’s current custom domain. It cannot be a Square Cloud domain (squareweb.app, squarecloud.app, …).

Response

string

Indicates whether the call was successful: success if it was, error if not.

On failure, the response includes an error code:

Status	Code	Meaning
`400`	`INVALID_DOMAIN`	The domain is not a valid fully qualified domain name.
`400`	`RESERVED_DOMAIN`	Square Cloud domains cannot be used as a custom domain.
`403`	`UPGRADE_REQUIRED`	The active plan does not include custom domains (Standard, Pro, or Enterprise required).
`403`	`LOAD_BALANCER_LIMIT_REACHED`	The plan’s limit of applications on this domain was reached.
`409`	`DOMAIN_ALREADY_EXISTS`	The domain is already attached to an application owned by another account.
`502`	`DNS_FAILED`	The domain attachment failed at the edge provider.

{
    "status": "success"
}
