* [Transaction IDs](#transaction-ids)

Every SDK call returns a response with a transaction ID in the `x-global-transaction-id` header. This transaction ID is useful for troubleshooting and accessing relevant logs from your service instance.

Assistant service = new Assistant("2019-02-28");

ListWorkspacesOptions options = new ListWorkspacesOptions.Builder().build();

Response<WorkspaceCollection> response;

try {

// In a successful case, you can grab the ID with the following code.

response = service.listWorkspaces(options).execute();

String transactionId = response.getHeaders().values("x-global-transaction-id").get(0);

} catch (ServiceResponseException e) {

// This is how you get the ID from a failed request.

// Make sure to use the ServiceResponseException class or one of its subclasses!

String transactionId = e.getHeaders().values("x-global-transaction-id").get(0);
