POST /api/domains/checkout

Request	`POST /api/domains/checkout`
Authentication	Session cookie required
Handler	`backend/domain_market.py`

What it does

Opens a payment session with the provider and returns its URL. Nothing is charged here and no domain is registered here; the callback confirms the payment with the provider before anything is credited.

Authentication

Session cookie required. Send the ff_session cookie. Without one the engine treats the caller as a new visitor with no holds and no claims, and returns a new cookie to use from then on.

Parameters

Parameter	In	Type	Required	Description
`ff_session`	cookie	`string`	Optional	The session identifier. Omit it on the first call and store the value the response sets; every later call must send the same one or the engine treats the caller as a new visitor with no holds and no claims.
`domain`	body	`string`	Required	The domain to buy.
`product_id`	body	`string`	Required	The product it is being bought for.

Request

The cookie jar carries the session between calls. Angle-bracketed values are the parameter types from the table above.
