Pay with PayPal using Adyen PSP

[rokridi]

Hello 👋

I am trying to use ASWebAuthenticationSession to allow the user to pay with PayPal via a PSP called Adyen.
The web content is displayed and the user can initiate the payment.
However the ASWebAuthenticationSession ’s completionHandler does not get called and an alert is displayed telling me that Safari could not open the url because it is invalid. (please see attachment).
I can’t figure out why it is not working. I would appreciate any kind of help.

Sample code:

let url = URL(string: "https://test.adyen.com/hpp/checkout.shtml?u=redirectPayPal&p=eJztVktv4zYQ-jX2JaDApx4HHWzL2jibblw3WbS9BBQ5irmxJVWinXh-fUey88B20w2KnooCBk3Pi8OZ7xt6qQ9LvQkafWj0ZuW6*3QUTUeca2udd3WlN7dWe42SkZiM1PSovYfDScJ5B5WF9tbUu8q3B-y20Ov4DNe93uzg2TJf9dso63V-CbOH1jujN2-4Xk5ny9bttYe-iXFKRZshmVtn3wjGQ0qFihPCtYqJVEIRXYRAdBgCDQWzMYQ-Pga22r2VbqX9WlcaNoHZta4a8akBr3e*ZiNJtYW9q7wOTL398THNuq7eqijGFeIsOoujM6nOKD1T4hRQZbiOi1ZXdoYdSY8NHpvrVhtodAuVTyklZShEwi1EQjJRRorFjBUQ01AnsdEQExA0NlxTJY0QwApC2diswdzXOx-4fzHYxHvYNn5hU8tVaXVcEGWNIZIaTQoFIVG4lonQLNIhi6TkCaeCcSUVy2bxfCJzPp-OBJ3nExVNRUbnWTSjlFPF6WwqBc3FnMWopzPOIpWxSagwxkyMT9gdCpWvxtgyvJI5-p7frMZbaA2200*OwEpfwPisWlQe7lrdUybwhwbS2fl89vHq5vr2w-zTfLWYfdcSQd-hdxqxZ-UKSuhPh1SFgkpaKEJNorEOVJKiEAVWMeEFBR6FNH7l5ndtlSFV049TMb1QYpVdXigeRerZ5hd3l8rygX*4ypNynv26XWLVzt00Ql7mG8Hy*YO*KNWX7gKazC3d3Uhk6Ox1PwGCqvauRIb2iZ-XnU-X3jfdgMMcP7pxwR9aBEVdEVO7KqjAH8W4Ivq2CBLSdA15gGJd1-e9zh6gOmpd9XLQyXiRpdSyUiU8JFaAIjIxEYlNGRIaypiJhGpa8vHJfLIdWsMoHf8-zP6Tw6yFBrQniC-vtoAjIy31pgOUdzery2-g*DRWunXdNNASD50PBsAdE-3WACUdtHtnoMPt8gTBCm1ddbcC61owPZ73rOdKjb092fwEfl3bkci-GRLInddtDtuBoJgoKo6pctUnq-p01Vv8UScGqVcc2hUbZ8iTuE-oRTvs30ObwXCoATZyXbfuK-QJ4S2G6*A2W05*W04ue8Nwh7VxR*n74IY*8Nhg0Qaf47QWsRhyDddbbQZ5wSQUXBZaWBpRHkqgDKKEykgqrblRKkG9oYmhcSFKyQvJwjIuASzFCyKRw9cPGlb2n75CLQ6LYfjAo4cWB0UGPRZybD60DYLepwIwcplYkkQljmNVaKIZs31VZWlpqSGx7ynOy1ndvWuGKeXbHYw76Pq34LPeOJxWh5RTjqNfEkavmURcU4GLYr*PT4gNPGxg4NOn3baANv0Of55s5z2703fz*Mmtf6qwvP3oTOco7yEOT8rLngSQli3BJ-Mke3m83lWJk9d1-17yMZajOv5X2RXBngcxZ0qwJBYIDEqTKPja-rxdq5v6Sx1*9hdrWz6W-nqd6cmV-FrmOVlUi5vY5rvHw*JP9yhHYg")!

Hello, This is Victoria Park from PPCP mobile SDK team. Are you currently using our mobile SDK and if so, can you let me know which version you are using? From your message, it appears that you are trying to invoke the PayPal checkout by passing a direct URL into ASWebAuthenticationSession. That approach isn’t supported by our SDK. If there are invalid characters in the URL, and if URL fails validation right away, iOS can display an alert immediately and never call the completion handler. Let me know how you’re integrating our SDK and I’d be happy to help.

Hello Victoria,

Thanks for replying.
I am not using PayPal's SDK.
I am relying on Payment Service Provider called Adyen like Stripe
I do not call PayPal directly to make payments, i am calling Adyen which is an intermediate.
The URL is given by Adyen to our backend then from the backend to the iOS application.
I am sorry, i should not have posted this here given the issue is not related to PayPal's SDK.
