Hi all,

I’ve built Practice API support into my integration, [Receipt Relay](https://receiptrelay.co.uk) (practice sign-in, client list, then filing for clients via X-Subdomain), and I’d like to test it before any practices use it.

Two questions:

1. How do developers get a sandbox practice account to test with?
2. Does my app need approving for the Practice API on live FreeAgent (I’ve seen the “Unknown Application” error mentioned in another thread), and if so, how do I request that?

I emailed [integrationsrequests@freeagent.com](mailto:integrationsrequests@freeagent.com) on 10 October but haven’t had a reply or acknowledgement yet, so I wanted to check this is the right route.

Thanks,  
John
