Thanks for your message. With the curl command I've managed to create a Sandbox API-key. However it would be nice to login to the sandbox app.
- With the curl command I just get a API-key, no login credentials for the app.
- When tinkering and making the 'tinker/user-overview.php' call I do get login credentials but these don't work.
- When manually singing up a new account for the sandbox app I do not receive the verification code.
I'm a bit stuck here, any help would be appreciated!
