Test and go live
Trustly provides a test environment. For Login ID/Personal number values, you can enter any digits, following the format YYMMDD-XXXX (for example: 111111-1111). 
You can check the status of Trustly test payments in your Customer Area > Transactions > Payments.
Before you can accept live Trustly payments, you need to submit a request for Trustly in your live Customer Area.
