Turn any Telegram channel with product links into a monetized feed in minutes.
This script listens to a source channel, detects the first URL in each new message, converts it to an AliExpress affiliate link, and reposts the updated message to a target channel automatically.

• Hands‑off monetization: keep posting as usual—links get converted automatically.
• Fast time‑to‑value: simple .env config, one command to run.
• Trackable results: uses your AliExpress tracking_id (PID) for attribution.

• Watches a source channel (SOURCE_CHANNEL_ID) for new messages.
• Parses the first URL in the message body (regex https?://\S+).
• Converts that URL into an AliExpress affiliate link using AliexpressApi (KEY, SECRET, TRACKING_ID required).
• Replaces the original URL with the affiliate one and forwards the message to the target channel (TARGET_CHANNEL_ID).
• Logs all important steps and errors; fully async on top of Telethon.

If there is no URL or if affiliate conversion fails, the script logs it and skips replacement.

1. Telethon starts a user session via PHONE_NUMBER (creates anon.session on first run).
2. @client.on(events.NewMessage(chats=SOURCE_CHANNEL_ID)) fires on each new message.
3. find_link_in_message() extracts the first URL.
4. generate_affiliate_link() calls aliexpress.get_affiliate_links(original_link) and picks promotion_link.
5. The message text is updated and sent to TARGET_CHANNEL_ID.

Flow diagram:

[Source Channel] --(Telethon)--> [Extract first URL] --(AliExpress API)--> [Replace URL]
         \__________________________________________________________________________/ 
                                      |
                                   Forward
                                      v

Requires Python 3.9+.

# 1) Create and activate a virtual environment (recommended)
python -m venv .venv
# Windows:
.venv\Scripts\activate
# macOS/Linux:
source .venv/bin/activate

# 2) Install dependencies
pip install -U telethon python-dotenv aliexpress-api
# Note: some forks of the AliExpress SDK use different names.
# If you see ImportError for `aliexpress_api`, try:
# pip install aliexpress-affiliate-api

Create a .env file in the project root:

# AliExpress Affiliate
KEY=your_aliexpress_app_key
SECRET=your_aliexpress_app_secret
TRACKING_ID=your_tracking_id   # PID / trackingId

# Telegram (user session)
API_ID=1234567
API_HASH=your_api_hash
PHONE_NUMBER=+380XXXXXXXXX

# Channel IDs (integer IDs; for supergroups/channels use -100XXXXXXXXXX)
SOURCE_CHANNEL_ID=-1001111111111
TARGET_CHANNEL_ID=-1002222222222

Notes

• Get API_ID/API_HASH at https://my.telegram.org.
• Use numeric IDs for private channels. You can fetch them via info bots or a small Telethon helper.

python main.py

On the first launch, Telethon will ask for a one‑time code in Telegram to create the local session (anon.session). After that, the script runs continuously and relays messages as they arrive.

• Replaces only the first URL per message (extendable to many).
• Designed for AliExpress links; non‑AliExpress URLs may be ignored by the SDK.
• Uses a user session (not a bot). Ensure the account can read from the source and post to the target channel.
• Verbose logging explains why a URL wasn’t replaced or a message wasn’t sent.

• ModuleNotFoundError: aliexpress_api → install aliexpress-api or try aliexpress-affiliate-api depending on the fork you use.
• Auth loop on first run → make sure the phone number is valid and you enter the Telegram login code promptly.
• Wrong channel IDs → verify you are using numeric IDs (often start with -100 for channels/supergroups).
• No messages forwarded → confirm the account has permissions in both channels and that messages actually contain URLs.

I can build for you custom Telegram bots, scripts, and automation solutions — fast, reliable, and scalable.

What I can do:

• Website automation (simulate user actions, form filling, scheduling)
• Data collection & web scraping (APIs or no-API scraping)
• Custom parsers for structured/unstructured data
• Chatbot development (Telegram, Discord, Slack, WhatsApp)
• Backend systems & API integrations

Goal: automate routine tasks, collect valuable data, and make your processes more efficient.
