Hello together, I am struggeling to get the following cURL call to work as a Java Snippet node: curl -X GET -H "x-sessiontoken: $2a$04$7UhCb2pm0aH.HUMm3Dn7lu" -H "Cache-Control: no-cache" -H "Postman-Token: bb01f25c-f1a9-79f8-b77c-0b7532b70629" [REST URL] I found the following code in the forum (https://tech.knime.org/forum/krest-nodes/api-call-with-authorization-token?destination=node%2F48743) but I don't know what needs to be changed to get it to work and output the JSON answer of the REST service. // system imports import org.knime.base.node.jsnippet.expression.AbstractJSnippet; import org.knime.base.node.jsnippet.expression.Abort; import org.knime.base.node.jsnippet.expression.Cell; import org.knime.base.node.jsnippet.expression.ColumnException; import org.knime.base.node.jsnippet.expression.TypeException; import static org.knime.base.node.jsnippet.expression.Type.*; import java.util.Date; import java.util.Calendar; import org.w3c.dom.Document; // Your custom imports: import javax.xml.bind.DatatypeConverter; import java.net.HttpURLConnection; import java.net.URL; import java.util.Map; import java.util.HashMap; import java.util.List; import java.io.PrintStream; import org.knime.core.node.NodeLogger; // system variables public class JSnippet extends AbstractJSnippet { // Fields for input columns /** Input column: "username" */ public String c_username; /** Input column: "password" */ public String c_password; /** Input column: "auth_url" */ public String c_auth_url; // Fields for output flow variables /** Output flow variable: "toLWSSO" */ public String out_toLWSSO; // Your custom variables: // expression start public void snippet() throws TypeException, ColumnException, Abort { // Enter your code here: String enc_auth = DatatypeConverter.printBase64Binary(String.format("%s:%s", c_username, c_password).getBytes()); try{ // Open connection HttpURLConnection httpUrlConnection = (HttpURLConnection) new URL(c_auth_url).openConnection(); // Clean Accept httpUrlConnection.setRequestProperty("Accept", "text/plain"); Map<String,String> headers = new HashMap<>(); headers.put("Authorization", "Basic " + enc_auth); // Add HTTP headers if (!headers.isEmpty()) { for (Map.Entry<String, String> entry : headers.entrySet()) { httpUrlConnection.setRequestProperty(entry.getKey(), entry.getValue()); } } // Set HTTP method httpUrlConnection.setRequestMethod("GET"); // Set response statusCode httpUrlConnection.getResponseCode(); Map<String, List<String>> responseHeaders = httpUrlConnection.getHeaderFields(); List<String> allrespHeaders = responseHeaders.get("Set-Cookie"); NodeLogger LOGGER = NodeLogger.getLogger(AbstractJSnippet.class); for(int i=0; i<allrespHeaders.size();i++){ String str = allrespHeaders.get(i); if(str.contains("COOKIE_KEY")){ out_token = str; LOGGER.warn("Found: " + str); } } } catch (Exception ex) {} // expression end } } Is anybody able to help me out with the necessary code or where I might find an answer on that? Any help is appreciated! Many thanks an best regards, Andy

Can you share how you fix this by REST nodes? I am also struggling in the authorization token.
