FAQ

Which LINE channel type should I create for this setup?

Create a LINE Login channel with app type Web app.

That’s the channel type that supports the OAuth callback flow used by enrolment forms.

Do I need to enable “Email address permission” in OpenID Connect?

Enable it if your enrolment flow requires an email.

Without it, LINE may not return an email for the user.

What callback URLs do I need to add?

Add one callback URL per environment.

The URL must match exactly and must include /auth/callback/line.

Use the patterns listed above for prod, QA, dev, and any custom domain.

Where do I find the LINE clientId and secret?

In the LINE Developers Console:

Your channel → Basic settings.

Copy the Channel ID into authentication.clientId and the Channel secret into authentication.secret.

How do I actually show the LINE button on the enrolment form?

Enable the provider in your enrolment form settings.

If you manage buttons via layout YAML, add - type: line under signinOptions.providers.
