Providers

A provider connects Casdoor to an external service, such as an identity provider for sign-in, an email service, or a cloud storage. You create a provider once and then add it to the applications that use it.

Provider categories

Who can use a provider

Only administrators create providers. Where a provider is available depends on who created it:

Created by	Available to
A global administrator: a user of the built-in organization, or a user with IsGlobalAdmin	All applications
An organization administrator: a user with IsAdmin	Applications of the same organization

Create a provider

1. In the Casdoor admin console, go to Identity > Providers and add a provider.
2. Select the Category and the Type. Casdoor fills in Name and Display name: the name follows the pattern provider_<category>_<type>, and the display name is <Category> <Type>. Casdoor stops updating a field once you edit it yourself.
3. Fill in the fields of the type. The page of each provider type lists them.
4. Save the provider.

Add a provider to an application

A provider takes effect only in the applications that you add it to.

1. Open the edit page of the application, go to the Providers tab, and add a row.

   

2. Select the provider. The list shows all providers that are available to the application.

   

3. For OAuth and captcha providers, set how the application uses them. See Add providers to an application and Configure the default captcha.

   

4. Save the application.
