Sell domains in your product

For site builders, agencies, onboarding flows and AI app builders that buy domains for their own customers.

The pattern

Your user types a name. Call search as they type, and suggest when it's taken.
They pick one. Create the order with their details as contact and your ID for them as external_ref.
Decide who pays (below). Show a checkout link if needed.
On order.completed, point the domain at the site you host for them.

Who pays

You pay, they pay you	Keep a balance topped up and use `payment: "balance"` or `"auto"`. Bill your customer however you already do. Domains register instantly.
They pay directly	Use `payment: "checkout"` and send them the `checkout_url`. The domain registers when they pay.

Keeping track

GET /domains?external_ref=your-customer-8271 lists one customer's domains.
Webhooks carry external_ref, so you can match events without storing our IDs.
The contact on each domain is the legal owner. Use your customer's details, not yours, unless you own it.

Partner pricing

Accounts that sell domains on get lower prices on every extension. Email hello@plonki.com.au with what you're building and rough monthly volume, or use Ask about partner pricing in Settings.

Testing

Build the whole flow with a plk_test_ key and a webhook pointed at your staging server. Test events arrive with test_mode: true.
