Once you've minted a CST, you can route your customer to the Diddo-hosted checkout page to complete their purchase. The hosted checkout handles the full payment experience — no additional frontend work required.
There are two ways to load it: a URL redirect for web, or a WebView for native iOS and Android apps.

🚀 Checkout URL
https://checkout.shopdiddo.com
Both methods below load this URL with the following required parameters:

|---|---|
cart_id | The ID of the user's cart |
auth_token | The CST minted via POST /checkout/cst |
