Create a payment order

POST

/v1/checkout

Access steps:

The server creates an order: pass in app_id + amount + user information + return url

Obtain the checkout_url, and the front-end will redirect, preferably redirecting on the current page instead of opening a new window

After successful payment, it will redirect back to the success_url, with checkout_id and 302_signature included in the query parameters.

The server uses the checkout_id to verify whether the payment is successful. If successful, proceed to the next step.

The webhook will pass 302_signature in the header to facilitate verification of whether the request is authentic.

Note: After calling the payment interface and the user completes the payment, the funds will be automatically transferred to your 302.AI account balance.
