Chapter 4. Managing authorizations by using the REST API

To automate the maintenance of Red Hat Developer Hub permission policies and roles, you can use Developer Hub role-based access control (RBAC) REST API.

You can perform the following actions with the REST API:

Retrieve information about:
- All permission policies
- Specific permission policies
- Specific roles
- Static plugins permission policies
Create, update, or delete:
- Permission policy
- Role

4.1. Sending requests to the RBAC REST API by using the curl utility

You can send RBAC REST API requests by using the curl utility.

Prerequisites

You have access to the RBAC feature.

Procedure

Find your Bearer token to authenticate to the REST API.
1. In your browser, open the web console Network tab.
2. In the main screen, reload the Developer Hub Homepage.
3. In the web console Network tab, search for the query?term= network call.
4. Save the token in the response JSON for the next steps.

In a terminal, run the curl command and review the response:

GET or DELETE request

curl -v \
  -H "Authorization: Bearer <token>" \
  -X <method> "https://<my_developer_hub_url>/<endpoint>" \

POST or PUT request requiring JSON body data

curl -v -H "Content-Type: application/json" \
  -H "Authorization: Bearer <token>" \
  -X POST "https://<my_developer_hub_url>/<endpoint>" \

4.3.4. User statistics

The licensed-users-info-backend plugin exposes various REST API endpoints to retrieve data related to logged-in users.

No additional configuration is required for the licensed-users-info-backend plugin. If the RBAC backend plugin is enabled, then an administrator role must be assigned to access the endpoints, as the endpoints are protected by the policy.entity.read permission.
