When working with TikTok’s API, it can be useful to retrieve the username associated with a specific user ID. In this article, we will explore three different ways to achieve this in Python.

Option 1: Using the TikTok API

The TikTok API provides a straightforward way to retrieve user information, including the username, given a user ID. To use this option, you will need to install the TikTok API library by running the following command:

pip install TikTokApi

Once the library is installed, you can use the following code to get the username for a specific user ID:

from TikTokApi import TikTokApi

api = TikTokApi()
user_id = "123456789"  # Replace with the desired user ID

user = api.getUser(user_id)
username = user['userInfo']['user']['uniqueId']

print(f"The username for user ID {user_id} is {username}")

This code initializes the TikTokApi object, retrieves the user information using the getUser() method, and extracts the username from the returned JSON response. Finally, it prints the username associated with the provided user ID.

Option 2: Web Scraping

If you prefer not to use the TikTok API, you can resort to web scraping to extract the username from the TikTok website. This option requires the installation of the BeautifulSoup library, which can be done by running the following command:

pip install beautifulsoup4

Once the library is installed, you can use the following code to scrape the username for a specific user ID:

import requests
from bs4 import BeautifulSoup

user_id = "123456789"  # Replace with the desired user ID

url = f"https://www.tiktok.com/@{user_id}"
response = requests.get(url)
soup = BeautifulSoup(response.text, 'html.parser')

username = soup.find('h1', {'class': 'share-title'}).text

print(f"The username for user ID {user_id} is {username}")

This code sends a GET request to the TikTok user’s profile page, parses the HTML response using BeautifulSoup, and extracts the username from the appropriate HTML element. Finally, it prints the username associated with the provided user ID.

Option 3: TikTok User Search

If you don’t have a specific user ID but want to search for a username, you can use the TikTok user search feature. This option requires the installation of the Selenium library, which can be done by running the following command:

pip install selenium

Once the library is installed, you can use the following code to search for a username:

from selenium import webdriver

username = "example_username"  # Replace with the desired username

driver = webdriver.Chrome()  # Replace with the appropriate driver for your browser
driver.get("https://www.tiktok.com/")
search_input = driver.find_element_by_css_selector('input[type="search"]')
search_input.send_keys(username)
search_input.submit()

username_element = driver.find_element_by_css_selector('h2.share-title')
username = username_element.text

print(f"The user ID for username {username} is {user_id}")

This code uses Selenium to automate the search process on the TikTok website. It opens the TikTok homepage, enters the desired username in the search input field, submits the search, and extracts the username from the appropriate HTML element. Finally, it prints the username associated with the provided username.

After exploring these three options, it is clear that using the TikTok API (Option 1) is the most efficient and reliable approach. It provides a direct and official way to retrieve user information, including the username, without the need for web scraping or browser automation. Therefore, Option 1 is the recommended solution for getting the username for a user ID in TikTok.
