Use this method when calling backchannel request directly from your application. See service-account example from demo for more details

                                                                                                                                               {
        ClientCredentialsProvider authenticator = deployment.getClientAuthenticator();
        authenticator.setClientCredentials(deployment, requestHeaders, formparams);
    }

setClientCredentials() [2/2]

static void org.keycloak.adapters.authentication.ClientCredentialsProviderUtils.setClientCredentials ( KeycloakDeployment  deployment, HttpPost  post, List< NameValuePair >  formparams  )

Don't use directly from your JEE apps to avoid HttpClient linkage errors! Instead use the method setClientCredentials(KeycloakDeployment, Map, Map)

                                                                                                                          {
        Map<String, String> reqHeaders = new HashMap<>();
        Map<String, String> reqParams = new HashMap<>();
        setClientCredentials(deployment, reqHeaders, reqParams);

        for (Map.Entry<String, String> header : reqHeaders.entrySet()) {
            post.setHeader(header.getKey(), header.getValue());
        }

        for (Map.Entry<String, String> param : reqParams.entrySet()) {
            formparams.add(new BasicNameValuePair(param.getKey(), param.getValue()));
        }
    }
