    <summary>2. Wait for incoming webhooks from Adyen and look at the status in outgoing webhook</summary>

Expectation - for `Adyen` the incoming webhook received for payout will be mapped to `initiated` - updating the payout status to `initiated` - the latest status (`initiated` in this case) should be propagated in the outgoing webhook.
