Progress in API

This tutorial describes how to use the Next Token with a custom web service.

This tutorial requires creating a LGDXRobot Cloud API Key but does not require authentication.

Prerequisites

1. Create a custom RESTful API for receiving the Next Token by using the following Python script.

from http.server import BaseHTTPRequestHandler, HTTPServer
import json

class Handler(BaseHTTPRequestHandler):
    def do_POST(self):
        length = int(self.headers['Content-Length'])
        body = self.rfile.read(length)
        data = json.loads(body)
        print(data)
        self.send_response(200)
        self.end_headers()
        self.wfile.write(b'OK')

HTTPServer(('', 8000), Handler).serve_forever()

2. Save the script as server.py and run it using python server.py.
3. Create an LGDXRobot Cloud API Key and note the secret key.
4. Create a trigger with the following properties:

In the body, set the following properties:

5. Create a new flow with two progress steps: Loading and Moving. The Proceed Condition for Loading is API, and the trigger is set to the trigger just created.

6. Connect a robot to LGDXRobot Cloud.

Completing the Progress

1. Create a new task using the flow just created. The waypoints can be any waypoints in the realm.

2. The robot will not move because the current progress is Loading.
3. Note the Task ID, Robot ID, and Next Token from the terminal running the Python script.

4. In Postman, create a new request https://localhost:5163/Automation/AutoTasksApi/AutoTaskNext and set the method to POST.
5. In the Headers tab, add a new key X-API-Key and set the value to the API Key.

6. In the Body tab, add a JSON object with the following properties:

{
  "taskId": <Task ID>,
  "robotId": "<Robot ID>",
  "nextToken": "<Next Token>"
}

7. Click Send.
8. The robot will move to the next waypoint.

Aborting the Task

1. Create a new task using the flow just created. The waypoints can be any waypoints in the realm.
2. The robot will not move because the current progress is Loading.
3. Note the Task ID, Robot ID, and Next Token from the terminal running the Python script.

4. In Postman, create a new request https://localhost:5163/Automation/AutoTasksApi/AutoTaskAbort and set the method to POST.
5. In the Headers tab, add a new key X-API-Key and set the value to the API Key.

6. In the Body tab, add a JSON object with the following properties:

{
  "taskId": <Task ID>,
  "robotId": "<Robot ID>",
  "nextToken": "<Next Token>"
}

7. Click Send.
8. The task will be aborted, and an email notification will be sent.
