I made application but nothing happened

I applied for an API key but the page didn’t do anything not sure if I have registered or not?

I have checked, and you do not have any API keys.
Go to https://developer.companieshouse.gov.uk/api/docs/ and click ‘Sign in / Register’ (top right).
Then click on ‘Your applications’ next to your email address. this will show all your API keys.
This is the also the page where you can click ‘Register an application’ to apply for a key.

cheers its working now
