Open a hosted checkout from a launch link
A launch link carries the checkout in its query string, so you can put it in an email, a button, or an iframe src. Every time the link is opened it creates a new checkout and redirects to it, so one link can be reused. Anyone holding the link can start a checkout with it.
It takes the same fields as POST /api/v1/payer/intake except metadata and the items’ required and metadata. Number the items from 1: item1_id, item1_description, item1_amount, item1_quantity, item1_category, then item2_…. Bracket names such as items[0][id] also work, and amount_cents is accepted for amount. For a single item you can send description and amount, with optional item_id (default ITEM-001) and quantity.
