Let's begin.

Prerequisites

Setting up Tuya

Add a cloud project and select your respective zone-based data centre.

After, the project is created - Go to the Service API tab and authorize Country and City Info API
Image description
Then go to Users tab and add your email and password details that you will use to authorise with python APIs.
Image description
Check the Overview tab for Access_ID and Access_Keys to be used with Python APIs.

Once these steps are complete you can move on to the code part.

Tuya API Explorer Environment

Tuya also provide API explore where you can try out the API requests before moving on to code,

It's easy to test and try out APIs without any setups and installations,

Python SDK for Tuya Cloud API requests

First, we have to import TuyaOpenAPI from Tuya Connecter that we installed before. We are also using streamlit for UI layouts.

from tuya_connector import (
TuyaOpenAPI
)
import streamlit as st

Next comes authorizing details (below details are available on your Overview Tab of Tuya Cloud Project

ACCESS_ID = "acbe*************123"
ACCESS_KEY = "abcderf*************"
API_ENDPOINT = "https://openapi.tuyain.com"
USERNAME = 'test@gmail.com'  # email address or phone number
PASSWORD = 'Job123'

Check your endpoint is correct according to your region,

Once those details are ready, it's time to connect TuyaOpenAPI

# Initialization of tuya openapi
openapi = TuyaOpenAPI(ENDPOINT, ACCESS_ID, ACCESS_KEY, AuthType.CUSTOM)
# on printing you would get response and uid for other usecases print(openapi.connect(USERNAME, PASSWORD))

Understanding the Country and City Request API, first let us try to get country code list through the API. The only parameter we need is "lang": "en"

country_codes = openapi.get("/v3.0/iot-03/all-countries", dict({"lang": "en"}))

st.json(country_codes)

Here is the response,

Let's also try some other API, which would reveal some more details of the country and city-based upon location sensor data (latitude and longitude). In the below API GET request, the required parameters are "lat" and "lon"(I used some random data)

city_info = openapi.get("/v1.0/iot-03/cities/positions", dict({"lat": "27.1751", "lon": "78.0421",                                                               }))
st.json(city_info)

Image description
Using the above API you get the following details:

  • city_name
  • province_name
  • parent_city_name
  • country_name

What next?

Basically, there are lots of fun stuff you can do with Tuya IoT and Cloud Platform. Need inspiration, check out my previous projects with Tuya Platforms:
