When a Card Transaction goes through SCA, the following occurs:

1. Treezor notifies you by sending a card3DSv2Authentication.create webhook.
2. You authenticate your end user using the SDK and an SCA method.
3. You inform Treezor of the authentication result using the dedicated endpoint.
4. Treezor notifies you of the final transaction status by sending a card3DSv2Authentication.update webhook.
