Create domain checkout link

<Info>This API is in beta. Endpoints, fields, and behavior may still change, so avoid depending on it in production.</Info>

Creates a one-time checkout link for buying a domain through Base44.

Not every workspace can buy domains through the API. For one that can't, the call is rejected and the domain has to be bought in the Base44 editor.

Pass domain to open checkout on that domain, and check it first with Check domain availability. Leave it out to open checkout on a domain search.

The person who opens the link pays at checkout, and nothing is bought until they finish. The domain is then attached to the app once it's registered, and appears in List custom domains.

Each call returns a new link and buys nothing, so retrying is safe, including after a timeout. The call fails while the checkout provider is unavailable.

Creating links is limited to 6 requests a minute and 20 an hour per caller. Some workspaces have a different limit.
