Can I link to the self registration URL from my app?

Luis B

I have enabled the "Self service registration" feature for my app, meaning Users have a button to create a new account in the login form. Clicking this button redirects to a different URL where the registration form is shown, the URL looks like

/oauth2/register?tenantId=xxxyyyzzz&client_id=aaabbbcccnonce=&pendingIdPLinkId=&redirect_uri=http%3A%2F%2Flocalhost%2Fmy-callback&response_mode=&response_type=code&scope=&state=&metaData...

Can I safely put a "Sign up" button in my app that points to this registration form URL, is there some documentation of what params are supported?

Thanks

If you click on the application magnifying icon and then look under integration details, you will get a generated link very similar to what you have above. This link can be inserted into your application and used to push users into a registration flow.

Thanks,

If you see an error message like https://YOURFUSIONAUTHSERVER/en?error=invalid_request&error_reason=missing_code_challenge&[…]The+request+is+missing+a+required+parameter%3A+code_challenge

it is because you have required PKCE for your application, but have not provided those parameters when attempting a login/registration. The links that we autogenerate in the app will not have a code_challenge by design, because those are dynamic for each request.

You can learn more about PKCE and turning it off on the applications core concepts page.
