  2. Open the Clients table in edit mode and add a new client for the i4connected.invitation app.

  3. Make sure to save your changes.

Setting up the User Invitation system app settings

In order to configure the User invitation application, please follow the below-described steps:

  1. Open a File Explorer window and locate the appsettings.json file under the i4-invitation-app folder.

  2. Open the appsettings.json file using an editor tool.

  3. The following settings are listed:

    1. OpenIDConnect – lists the settings needed for the interaction/communication of the Invitation Application with the Identity and Access Management system (IAM):

      1. ClientId - sets the i4connected invitation system client ID.

      2. ClientSecret - sets the i4connected Invitation system client secret.

      3. Authority - sets the i4connected authority URL.

      4. ResponseType - sets the type of data contained in the response.

      5. CallbackPath - sets the path where the server will redirect during authentication.

    2. ConnectedApi

      1. BaseAddress - sets the i4connected API endpoint address

      2. IsNative - enables/disables the native mode.

        In native mode, accepting an invitation will redirect the user to i4Identity, where he/she will be able to log in with an existing account or register a new account in the system. The new user will be created by the identity module, an email will be sent to the user for account confirmation, and the user will be able to log in with the credentials they’ve set up.

    3. ConnectedTranslation

      • Namespace - describes which translation namespace should be used to translate the texts.

    4. RedirectUri - sets the redirect URI, which is the callback entry point of the application. This setting will overwrite the RedirectUri of the OpenIdConnect provider.

    5. RegistrationLink - sets an optional registration link.

    6. PortalRedirectUri - sets the portal redirect URI, which occurs each time a user successfully accepts an invitation.


      The portal redirect URI should be different than the initial entry point of the application.

  4. Fill in the custom values and save the appsettings.json file changes.
