Paypal Cordova Plugin or InAppBrowser?


Hi, I want to integrate Paypal Cordova Plugin on my Ionic project.
I have created paypal developer test account and working with Sandbox.
In test mode with Client ID (SANDBOX API CREDENTIALS) everything is ok,
but when I try to use Live Client ID for Direct credit cards I have received this message:

PayPal return this error
Note: Direct credit card processing is not available for you when using REST APIs. Your live credentials are inoperable for direct credit card processing for your country but your test credentials are enabled for sandbox testing.

Now I decided to use InAppBrowser
Is there anybody here who implemented Paypal payments with InAppBrowser.

Sorry for my bad English
