​
Overview

The /remove command removes a specific Amazon product from your tracking list. All associated data, including price history, will be permanently deleted.

​
Syntax

/remove [amazon_url]
​
amazon_url
string
required
The Amazon product URL or a partial URL/title to identify the product
Removal is permanent. All price history for the product will be lost. Use caution with this command.

​
How It Works

  1. URL Sanitization - Cleans the provided URL
  2. Exact Match - Searches for a product with the sanitized URL
  3. Fuzzy Match - If exact match fails, searches by partial URL or title
  4. Deletion - Removes the product from the database
  5. Confirmation - Sends a success message with the product name

​
Examples

​
Remove by Full URL

/remove https://www.amazon.com/dp/B08N5WRWNW
Bot Response: 
🗑️ Producto eliminado:
Apple AirPods Pro (2nd Generation)

​
Remove by Partial URL

/remove B08N5WRWNW
Bot Response: 
🗑️ Producto eliminado:
Apple AirPods Pro (2nd Generation)

​
Remove by Title (Partial Match)

/remove AirPods Pro
Bot Response: 
🗑️ Producto eliminado:
Apple AirPods Pro (2nd Generation)
You don’t need the full URL. Any unique identifier from the URL or product title works.

​
Product Not Found

If the product doesn’t exist: 
/remove https://www.amazon.com/dp/INVALID123
Response: 
⚠️ No se encontró producto con esa URL.
Usa /list para ver tus productos.

​
Code Implementation

The /remove command is implemented in index.mjs:520-542:
index.mjs
bot.onText(/\/remove (.+)/, (msg, match) => {
  const chatId = msg.chat.id;
  const raw = match[1].trim();
  const sanitized = sanitizeAmazonURL(raw);

  if (priceData[sanitized]) {
    const title = priceData[sanitized].title || sanitized;
    delete priceData[sanitized];
    saveData();
    return bot.sendMessage(chatId, `🗑️ *Producto eliminado:*\n${escapeMD(title)}`, { parse_mode: "Markdown" });
  }

  // Sometimes user passes a key that is not sanitized; try find by partial match
  const foundKey = Object.keys(priceData).find(k => k.includes(raw) || (priceData[k].title && priceData[k].title.includes(raw)));
  if (foundKey) {
    const title = priceData[foundKey].title || foundKey;
    delete priceData[foundKey];
    saveData();
    return bot.sendMessage(chatId, `🗑️ *Producto eliminado:*\n${escapeMD(title)}`, { parse_mode: "Markdown" });
  }

  bot.sendMessage(chatId, "⚠️ No se encontró producto con esa URL.\nUsa /list para ver tus productos.", { parse_mode: "Markdown" });
});

​
Matching Logic

​
Step 1: Exact Match

The bot first tries to match the sanitized URL exactly: 
const sanitized = sanitizeAmazonURL(raw);
if (priceData[sanitized]) {
  // Found exact match
  delete priceData[sanitized];
}

​
Step 2: Fuzzy Match

If no exact match, it searches for partial matches: 
const foundKey = Object.keys(priceData).find(k => 
  k.includes(raw) || 
  (priceData[k].title && priceData[k].title.includes(raw))
);
This allows removal by:
  • Partial URL (e.g., /dp/B08N5WRWNW)
  • Product ID (e.g., B08N5WRWNW)
  • Title keywords (e.g., AirPods)
Fuzzy matching returns the first product that contains the search term. If multiple products match, only the first is removed.

​
Alternative: Remove via /list

You can also remove products interactively through the /list command:
  1. Run /list
  2. Click on the product you want to remove
  3. Click the 🗑️ Eliminar button
Result: 
🗑️ Producto eliminado:
Apple AirPods Pro (2nd Generation)
This method is safer as you can visually confirm which product you’re removing.

​
Bulk Removal

To remove ALL products at once, use the bulk delete feature in /list:
  1. Run /list
  2. Click 🗑️ Eliminar todos
Result: 
🗑️ Se eliminaron 5 productos.
Bulk deletion removes ALL tracked products and their complete price history. This cannot be undone.

​
Use Cases

​
Product Already Purchased

After buying a product, remove it from tracking: 
/remove https://www.amazon.com/dp/B08N5WRWNW

​
No Longer Interested

Remove products you’ve decided not to buy: 
/remove Samsung Galaxy S23

​
Incorrect URL Added

Quickly remove a product that was added by mistake: 
/add https://www.amazon.com/wrong-product
/remove wrong-product

​
Cleanup Before New Tracking Period

Clear old products before a new shopping season: 
/list
# Click "🗑️ Eliminar todos"

​
Best Practices

Tips for safe removal:
  • Use /list to view products before removing
  • Copy the full URL from /list for exact removal
  • Use the interactive delete button in /list for visual confirmation
  • For bulk cleanup, use the “Eliminar todos” button

​
Data Deletion

When a product is removed, the following data is deleted:
  • Product URL and title
  • Current price
  • Lowest price ever recorded
  • Complete price history (all historical data points)
  • Product image URL
  • Added date and last checked timestamp
  • Chat ID of who added it
The deletion only affects the product data. Your chat registration remains active for future product tracking.

​
Persistence

Changes are immediately saved to the prices.json file: 
delete priceData[sanitized];
saveData();
This ensures the removal persists across bot restarts.
  • /add - Add a product to tracking
  • /list - View all tracked products
  • /edit - Update a product URL instead of removing
  • /stats - View statistics about tracked products
