Re: VTC - how can we simulate delivery of notification
Yes, you can get static sample alerts delivered in Sandbox. In order to do that, you need to create a project on VDP (developer.visa.com) and add VTC API to the project.
Once the VTC project is created, you can go to your project dashboard and click on Configuration section to add the outbound API configuration where you provide your end point URL to receive the alerts. Once you submit the same, it comes to Visa for approval. Post approval, you can test the Notification alerts in sandbox environment.
Please go through the below link for setting up outbound URL and the pre-requisties required on your end.
