Create a link for a drop, a tip, a subscription or the profile

Creates one link id. The link is https://www.dropfans.io/buy/{id} (web) and https://t.me/<bot>/app?startapp={id} (Telegram), with no parameters. The drop, the tip amount and your externalRef are stored with the id.

• buy: a drop (productId from create-drop) opens its checkout. A subscriber-only drop opens the subscribe sheet instead.
• tip: opens the tip sheet, prefilled with amountUsd when you set one ($5–$750), or the fan picks.
• subscribe: opens the subscribe sheet. profile opens the profile.

externalRef (1–32 of A-Z a-z 0-9 _ -) comes back on the sale: the drop.paid / tip.paid webhooks and GET /orders and /tips, together with the link's linkId. One link per fan per drop is the usual pattern.

The same request always returns the same link, so it's safe to call again. With a key that belongs to an app, sales through the link earn your app owner commission for life, and the call makes your app the account's connected CRM.
