Describe the bug

In the Demo APP, when selecting the Native checkout mode and replacing the Client ID with my own account's ID (without modifying the Order ID), I observed the following:

1. received an error delegate callback.
   

2. then the app shows a payment page, click the complete
   

3. at last receive a complete callback
   

4. I consistently encountered this screen when I replaced the order ID with my own. A 'Review Order' button is at the bottom but not a 'Complete Order' button. When I clicked it, the popup just disappeared.

If an error callback is received, the flow should be stopped and not proceed with the payment.

Is this SDK in a stable release or beta/preview version?

[KunJeongPark]

Thank you for your interest in our SDK.
The demo app uses hard coded clientID and sandbox merchant credentials in our test merchant server.

If you hard code another clientID, the demo app will not work properly.

@KunJeongPark Thanks. Regarding the issue described in the fourth scenario above, when I used my Client ID and Order ID, the 'Review Order' is on the screen instead of the 'Complete Order'. Please help me understand what might be the problem in this case.

[KunJeongPark]

I'm not sure but it is not a flow that is supported by the demo app, modifying the demo app to include a different client ID.

[citcon-aoyansheng]

The same thing happened when I integrated the SDK separately in my app. It also shows the 'Review order'

[KunJeongPark]

It is the same with your own app, you need server side integration. ClientID is only for use in the SDK.

It looks like you are using PayPalCheckoutSDK which is wrapped in our PayPalNativeCheckout module and that SDK along with the PayPalNativeCheckout module is being deprecated. We are only addressing existing merchants' critical security bugs for that module. We are directing our merchants to use PayPalWebPayments.

Currently, I have not used the backend server. I created the order using the Client ID and Secret in the Postman and obtained the Order ID. Then set the Client ID and Order ID in the demo app, which is when the problem occurred. Even if I use PayPalWebPayments, it's the same.
