### Initialize ClientTransaction and Generate IDs

Source: https://context7.com/isarabjitdhiman/xclienttransaction/llms.txt

Demonstrates the full workflow of fetching required assets from X.com and generating transaction IDs for specific API endpoints.

```python
import bs4
import requests
from urllib.parse import urlparse
from x_client_transaction import ClientTransaction
from x_client_transaction.utils import generate_headers, get_ondemand_file_url

# Initialize session with required headers
session = requests.Session()
session.headers = generate_headers()

# Fetch the X.com home page
home_page = session.get(url="https://x.com")
home_page_response = bs4.BeautifulSoup(home_page.content, 'html.parser')

# Fetch the ondemand.s JavaScript file
ondemand_file_url = get_ondemand_file_url(response=home_page_response)
ondemand_file = session.get(url=ondemand_file_url)
ondemand_file_response = ondemand_file.text

# Initialize the ClientTransaction object
ct = ClientTransaction(
    home_page_response=home_page_response,
    ondemand_file_response=ondemand_file_response
)

# Generate transaction IDs for different endpoints
# Example 1: POST request to client_event endpoint
url = "https://x.com/i/api/1.1/jot/client_event.json"
path = urlparse(url=url).path  # /i/api/1.1/jot/client_event.json
transaction_id = ct.generate_transaction_id(method="POST", path=path)
print(f"Transaction ID: {transaction_id}")

# Example 2: GET request to GraphQL UserByScreenName endpoint
graphql_url = "https://x.com/i/api/graphql/1VOOyvKkiI3FMmkeDNxM9A/UserByScreenName"
graphql_path = urlparse(url=graphql_url).path
user_transaction_id = ct.generate_transaction_id(method="GET", path=graphql_path)
print(f"User Lookup Transaction ID: {user_transaction_id}")

# Use the transaction ID in API requests
api_headers = {
    **session.headers,
    "X-Client-Transaction-Id": transaction_id
}
```

### Integrate X Client Transaction with requests

Source: https://context7.com/isarabjitdhiman/xclienttransaction/llms.txt

Demonstrates creating a session, fetching required assets, and performing an authenticated API request with a generated transaction ID.

```python
import bs4
import requests
from urllib.parse import urlparse
from x_client_transaction import ClientTransaction
from x_client_transaction.utils import generate_headers, get_ondemand_file_url

def create_x_api_session():
    """Create a fully configured session for X API requests."""
    session = requests.Session()
    session.headers = generate_headers()

    # Fetch required pages
    home_page = session.get(url="https://x.com")
    home_page_response = bs4.BeautifulSoup(home_page.content, 'html.parser')

    ondemand_url = get_ondemand_file_url(response=home_page_response)
    ondemand_file = session.get(url=ondemand_url)

    # Create transaction generator
    ct = ClientTransaction(
        home_page_response=home_page_response,
        ondemand_file_response=ondemand_file.text
    )

    return session, ct

def make_api_request(session, ct, url, method="GET", **kwargs):
    """Make an authenticated API request with transaction ID."""
    path = urlparse(url=url).path

# }

# Use with requests
import requests
session = requests.Session()
session.headers = headers
response = session.get("https://x.com")

# Use with httpx
import httpx
client = httpx.Client(headers=headers)
response = client.get("https://x.com")
```

)

async def generate_transaction_id_async():
    # Initialize async client
    async with httpx.AsyncClient(headers=generate_headers()) as session:
        # Handle migration and get home page
        home_page_response = await handle_x_migration_async(session=session)

        # Alternative: Direct fetch for x.com (no migration needed)
        # home_page = await session.get(url="https://x.com")
        # home_page_response = bs4.BeautifulSoup(home_page.content, 'html.parser')

        # Fetch ondemand file
        ondemand_file_url = get_ondemand_file_url(response=home_page_response)
        ondemand_file = await session.get(url=ondemand_file_url)
        ondemand_file_response = ondemand_file.text

session.headers = generate_headers()


# GET HOME PAGE RESPONSE
# required only when hitting twitter.com but not x.com
# returns bs4.BeautifulSoup object
home_page_response = handle_x_migration(session=session)

# for x.com no migration is required, just simply do
home_page = session.get(url="https://x.com")
home_page_response = bs4.BeautifulSoup(home_page.content, 'html.parser')


# GET ondemand.s FILE RESPONSE
ondemand_file_url = get_ondemand_file_url(response=home_page_response)
ondemand_file = session.get(url=ondemand_file_url)

ondemand_file_response = bs4.BeautifulSoup(ondemand_file.content, 'html.parser')
# Getting "Couldn't get KEY_BYTE indices" error? Try passing the original response or the response text
# both should work
# ondemand_file_response = ondemand_file
ondemand_file_response = ondemand_file.text
```

--------------------------------

### Handle Twitter to X.com Migration (Synchronous)

Source: https://context7.com/isarabjitdhiman/xclienttransaction/llms.txt

Automatically handles the Twitter to X.com domain migration process. Use this function when performing synchronous requests. It returns a BeautifulSoup object of the final home page.

```python
import requests
from x_client_transaction.utils import generate_headers, handle_x_migration, get_ondemand_file_url

# Initialize session
session = requests.Session()
session.headers = generate_headers()

# Handle migration automatically (works for both twitter.com and x.com)
# Returns a BeautifulSoup object of the final home page
home_page_response = handle_x_migration(session=session)

# The response contains the verification key in meta tags
verification_key = home_page_response.select_one(
    "meta[name='twitter-site-verification']"
)
print(f"Verification key found: {verification_key is not None}")

# Continue with ondemand file fetch
ondemand_url = get_ondemand_file_url(response=home_page_response)
print(f"Ondemand file URL: {ondemand_url}")
```

### Generate Transaction IDs with Custom Parameters

Source: https://context7.com/isarabjitdhiman/xclienttransaction/llms.txt

Shows how to generate transaction IDs using the ClientTransaction instance, including optional custom timestamps for testing.

```python
from x_client_transaction import ClientTransaction

# Assuming ct is an initialized ClientTransaction instance
# Generate transaction ID with default parameters
transaction_id = ct.generate_transaction_id(
    method="GET",
    path="/i/api/graphql/ABC123/TweetDetail"
)

# Generate with custom timestamp (useful for testing)
import math
import time

custom_time = math.floor((time.time() * 1000 - 1682924400 * 1000) / 1000)
transaction_id_with_time = ct.generate_transaction_id(
    method="POST",
    path="/i/api/1.1/statuses/update.json",
    time_now=custom_time
)

# The transaction ID can be used directly in request headers
headers = {
    "X-Client-Transaction-Id": transaction_id,
    "Authorization": "Bearer YOUR_TOKEN",
    "Content-Type": "application/json"
}
```

### Asynchronous Twitter API Request with X-Client-Transaction-ID

Source: https://github.com/isarabjitdhiman/xclienttransaction/blob/master/README.md

Shows how to perform asynchronous requests to the Twitter API, including session initialization with generated headers, handling X migration, and fetching the ondemand.s file. This is necessary for generating the transaction ID in an async environment.

```python
import bs4
import httpx
from x_client_transaction.utils import generate_headers, handle_x_migration_async, get_ondemand_file_url

# INITIALIZE SESSION
session = httpx.AsyncClient(headers=generate_headers())


# GET HOME PAGE RESPONSE
# required only when hitting twitter.com but not x.com
# returns bs4.BeautifulSoup object
home_page_response = await handle_x_migration_async(session=session)

# for x.com no migration is required, just simply do
home_page = await session.get(url="https://x.com")
home_page_response = bs4.BeautifulSoup(home_page.content, 'html.parser')


# GET ondemand.s FILE RESPONSE
ondemand_file_url = get_ondemand_file_url(response=home_page_response)
ondemand_file = await session.get(url=ondemand_file_url)

ondemand_file_response = bs4.BeautifulSoup(ondemand_file.content, 'html.parser')
# Getting "Couldn't get KEY_BYTE indices" error? Try passing the original response or the response text
# both should work
# ondemand_file_response = ondemand_file
ondemand_file_response = ondemand_file.text
```

--------------------------------

### Generate X-Client-Transaction-Id

Source: https://github.com/isarabjitdhiman/xclienttransaction/blob/master/README.md

Generates the X-Client-Transaction-Id using the ClientTransaction class. Requires the home page and ondemand.s file responses obtained from previous steps. The method and path of the target API endpoint are needed for generation.

```python
from urllib.parse import urlparse
from x_client_transaction import ClientTransaction


# Example 1
# replace the url and http method as per your use case
url = "https://x.com/i/api/1.1/jot/client_event.json"
method = "POST"
path = urlparse(url=url).path
# path will be /i/api/1.1/jot/client_event.json in this case

# Example 2
user_by_screen_name_url = "https://x.com/i/api/graphql/1VOOyvKkiI3FMmkeDNxM9A/UserByScreenName"
user_by_screen_name_http_method = "GET"
user_by_screen_name_path = urlparse(url=url).path
# path will be /i/api/graphql/1VOOyvKkiI3FMmkeDNxM9A/UserByScreenName in this case


ct = ClientTransaction(home_page_response=home_page_response, ondemand_file_response=ondemand_file_response)
transaction_id = ct.generate_transaction_id(method=method, path=path)
transaction_id_for_user_by_screen_name_endpoint = ct.generate_transaction_id(
    method=user_by_screen_name_http_method, path=user_by_screen_name_path)

print(transaction_id)
print(transaction_id_for_user_by_screen_name_endpoint)

```

--------------------------------

### Extract Ondemand File URL

Source: https://context7.com/isarabjitdhiman/xclienttransaction/llms.txt

Extracts the URL of the ondemand.s JavaScript file from the home page HTML. This file is crucial for transaction ID generation. The function requires a BeautifulSoup object of the home page.

```python
import bs4
import requests
from x_client_transaction.utils import generate_headers, get_ondemand_file_url

# Fetch home page
session = requests.Session()
session.headers = generate_headers()
home_page = session.get(url="https://x.com")
home_page_response = bs4.BeautifulSoup(home_page.content, 'html.parser')

# Extract ondemand file URL
ondemand_url = get_ondemand_file_url(response=home_page_response)
print(f"Ondemand URL: {ondemand_url}")
# Output: https://abs.twimg.com/responsive-web/client-web/ondemand.s.<hash>a.js

# Fetch the ondemand file
ondemand_response = session.get(url=ondemand_url)

# Can pass as text or BeautifulSoup object to ClientTransaction
ondemand_text = ondemand_response.text
# or
ondemand_soup = bs4.BeautifulSoup(ondemand_response.content, 'html.parser')
```
