Hello I'm trying to integrate Adyen within paypal and stuck with next issue. I'm going to grant API permissions page and doing next steps: 1. I'm filling out Third Party Permission Username field with "paypal_api2.adyen.com" 2. Clicking on lookup field 3. And getting "Please enter valid API username." error I found in adyen documentation that this API user name is valid. It would be great if you can help me with this. Thanks.
