Adding-new-endpoints.md

+# Adding new endpoints
+
+Adding new endpoints is done by adding either a new controller or a new mapping in an existing controller.
+
+Controllers are described in this article:
+
+[[Server Components]]
+
+Looking at the example of a controller [Server Components](Server Components#Controllers)
+
+```java
+@RestController
+public class ObjectiveController {
+
+	private final ObjectiveService objectiveService;
+
+	public ObjectiveController(ObjectiveService objectiveService) {
+		super();
+		this.objectiveService = objectiveService;
+	}
+
+	@PostMapping("/objective-complete")
+	public ResponseEntity<Object> authenticateObjective(@RequestBody ObjectiveRequest request) throws JsonProcessingException {
+		int response = objectiveService.completeObjective(request);
+		ObjectiveResponse responseObj = new ObjectiveResponse(response);
+	return new ResponseEntity<>(responseObj.toJSON(), HttpStatus.OK);
+	}
+}
+```
+
+Adding a GET mapping to this page would look like this:
+
+```java
+@RestController
+public class ObjectiveController {
+
+	private final ObjectiveService objectiveService;
+
+	public ObjectiveController(ObjectiveService objectiveService) {
+		super();
+		this.objectiveService = objectiveService;
+	}
+
+	@PostMapping("/objective-complete")
+	public ResponseEntity<Object> authenticateObjective(@RequestBody ObjectiveRequest request) throws JsonProcessingException {
+		int response = objectiveService.completeObjective(request);
+		ObjectiveResponse responseObj = new ObjectiveResponse(response);
+	return new ResponseEntity<>(responseObj.toJSON(), HttpStatus.OK);
+	}
+        
+       @GetMapping("/logout/{objectiveID}")
+       public ResponseEntity<Object> logoutPlayer(@PathVariable("objectiveID") int objectiveID) {
+            int response = objectiveService.getObjective(objectiveID);
+            return new ResponseEntity<>(response, HttpStatus.OK); 
+       }
+}
+```
+The `{objectiveID}` is a variable in the url for the Objective's ID. It is automatically passed in when Spring Boot receives the GET request.
