I'm experimenting on a BC Cloud Sandbox. I've navigated to the Service Connections page and selected HMRC VAT Setup. A page with the title: 'Edit - OAuth 2.0 Setup - HMRC VAT' is then displayed. My question is:
How do I change the Service URL on this page from the live environment to test?
(i.e.)
From:
https://api.service.hmrc.gov.uk
to
https://test-api.service.hmrc.gov.uk
... it appears to be read only?
