# Create Payment Link

Create a payment link for collecting payments from customers. Supports **one-time** (default) or **recurring** links. Auth: Bearer token with scope `external.apis`. Use `checkoutType: "recurring"` and `recurringCharge` for subscription, consumption, or seating billing. For `POST /v1/ext/collections/payment-link`, `itemDeliveryAddress` and `cartItems` are required, and each cart item must include at least `name` and `description`.
