Hi getting same
import { InAppBrowser } from ‘@ionic-native/in-app-browser’;
constructor(public iab: InAppBrowser){}

[ts] Property ‘InAppBrowser’ does not exist on type ‘CheckoutCarPage’.

after user closed means it has to redirect to some page
how i can do that ?

oops, should have been:

this.iab.open(this.url, ‘_self’, ‘location=yes’);

no, haven’t done sth like this. I use the iab to get Login Cookies.
