Transaction Emulator error

[MDL]

Hello,
I'm trying to use Visa Transaction Alerts API. I successfully created a customer a POST https://sandbox.api.visa.com/vta/v3/communities/{community-code}/customers. Now I'm trying to emulate transactions using the Transaction Emulator but when I click on emulator "submit" button I get the following error : "Invalid Request ( Note : Please make sure to register the card using run time API calls before using it in emulator. )".
As I successfully registered the card through customer creation the problem seems to be elsewhere.

Can you help me please?
