[SOLVED] Version 4.0 localhost testing getting 3228 : The ThreeDSNotificationURL field format is invalid

Version 4.0 localhost testing getting 3228 : The ThreeDSNotificationURL field format is invalid

I am currently testing the changes for version 4.0 of the protocol for PSD2 using Direct Integration.

I am running under Visual Studio using a localhost website address.

When calling the SagePay payment endpoint with ThreeDSNotificationURL set as a localhost address (http://localhost:15536/Payments/ThreeDResponse) I receive the following error '3228 : The ThreeDSNotificationURL field format is invalid.'

If I change this field to a fully qualified domain (http://www.google.com) I no longer receive the error, but can't complete my testing.

Using localhost for the termurl in version 3.0 of the protocol works as expected.

Solution

Did you URL encode the ThreeDSNotificationURL in your post? I send it like that and it is ok: sb.Append(HttpUtility.UrlEncode("https://www.clientdomian.com/ac/ThreeDSNotificationURL.aspx")); I run the site on my local IIS for development.
