Custom provider troubleshooting

Suggestions for troubleshooting problems that could crop up when working with custom providers.

A custom provider button doesn't work
Verify that you’ve correctly entered the custom provider in the authentication.provders setting. (Admittedly, it can be a bit tricky.)
A custom provider button isn't visible
Most likely you forgot to add the custom provider to the authentication.provders setting.
A custom provider button has an odd-looking label
Make sure you’ve entered the correct value in the authentication.providers.custom setting. And make sure you have an authentication.providers.custom setting.
Custom provider users can't log on to Hosted Login
Our advice? Start by checking the redirect back from the social login identity provider.
No user data is shown in the Complete Your Registration screen
Typically this is because: 1) you didn’t include an attribute map; or, 2) there’s a problem with your attribute map.
The scopes you requested aren't being returned
First, make sure you included an attribute map. Second, make sure those scopes are supported by the social login identity provider.
You don't know the endpoints required to create a custom provider
