The ImportOAuth program

Use the ImportOAuth program to register the mandatory URL endpoints based on the OAuth2 identity provider (IdP) URL.

With the Genero ImportOAuth program, you can:

Register a new OAuth2 identity provider (IdP).
List all registered OAuth2 IdPs.
Remove OAuth2 IdP identified by its URI.

The ImportOAuth.4gl source code is provided in $FGLDIR/web_utilities/services/openid-connect/src/, and the compiled version is in the bin directory.

Syntax

ImportOAuth [ options ] IdP

options are described in Table 1.
IdP is the URL of an OAuth2 identity provider.

Note: The ImportOAuth tool command line follows the convention of other Genero command line tools for both short and long versions of options.

Table 1. ImportOAuth options
Option	Description	Usage example
`-h, --help`	Display help with the command.	`fglrun ImportOAuth -h`
`-l, --list`	List all imported IdPs stored in the database.	`fglrun ImportOAuth -l`
`-r, --remove`	Remove the OAuth2 entry for the specified IdP from the database.	`fglrun ImportOAuth -r https://www.instagram.com`
`-i, --import`	Import the IdP endpoints and register them in the database for OAuth2.	See Import option usage example
`-a, --authz IdP_endpoint`	OAuth2 authorization end point URL (mandatory).	See Import option usage example
`-t, --token IdP_endpoint`	OAuth2 token end point URL (mandatory).	See Import option usage example
`-o, --logout IdP_endpoint`	OAuth2 logout end point URL (optional).	See Import option usage example
`-k, --keys IdP_endpoint`	OAuth2 public JWK keys URL (recommended). Not all OAuth providers have public keys; however, if an IdP public keys URL is available, provide it to get the ID token signature validated.	See Import option usage example
`-p, --profile IdP_endpoint`	OAuth2 user profile end point URL (optional).	See Import option usage example

Import option usage example

To import an IdP as OAuth2, you must execute the ImportOAuth program with the --import option. This example provides the command for Instagram; line breaks have been added for readability.

fglrun ImportOAuth --import 
            --authz https://api.instagram.com/oauth/authorize 
            --token https://api.instagram.com/oauth/access_token 
            --logout https://instagram.com/accounts/logout 
            --profile https://api.instagram.com/v1/users/self?
            https://www.instagram.com

The first two parameters --authz and --token are mandatory, and the endpoint URLs of the IdP are required:

--authz URL: mandatory authorization endpoint URL.
--token URL: mandatory token endpoint URL.
--logout URL: optional logout endpoint URL.
--profile URL: optional user profile endpoint URL.
URL of the IdP: mandatory

Important: The profile URL requires an access_token to get user profile information. In some cases, the access_token must be provided via the query string (for example, Instagram requires it). Therefore you must add an ending question mark (?) during importation so that OpenID-Connect service providers know how to generate that request.
