Secure Webhook URL Modification

Job ID: 40494116

Budget: $30 – $250 USD

I currently have a working Python webhook, but I need a new version with a small modification.

Current URL:

http://134.209.114.100:5000/webhook?phone=59995150121

Desired URL:

http://134.209.114.100:5000/x3f?p=2219821478767

The goal is to make the phone number unreadable to users.

The value 59995150121 is the phone number where the system sends WhatsApp alerts. Instead of exposing the phone number in the URL, I want it encoded into a number using a simple math formula.

Example:

Phone number: 1234

Encoding formula:
1234 * 23 + 9842

The webhook should then use the reverse formula to decode the value back to 1234 before processing the alert.

Requirements:

Create a new webhook based on the existing one.
Do not modify the current webhook.
Use a new route name (for example: /x3f).
No database.
Keep the formula simple and lightweight.
Minimal processing to avoid any delay.
All other functionality must remain exactly the same.

my budget is $40.
