Explore the oauth-keycloak sample collections for real-world OAuth2 flows to walk through each grant type step by step:

Some APIs will require a digital certificate to establish a client’s identity. You can add your certificate authority (CA) or client certificates to Bruno. See Add and Manage Certificates for more information.

You can pass auth details along with any request in Bruno in the header, body, or as a parameter. If you enter your auth details to the Auth tab of your requests, we will automatically populate the relevant parts of the request for your chosen auth method.
