WHMCS Telegram Bot

Customer support + sales over Telegram, native in WHMCS

WHMCS WHMCS 8.13 PHP 8.1+ 5.0 / 5

Let customers check invoices, open tickets, see service status, request renewals and even pay - all through Telegram chat. Admins get instant push notifications and can reply to tickets without leaving Telegram.

Key features

  • Customer commands: /invoices, /services, /tickets, /domain, /renew, /pay
  • Admin commands: /search, /assign, /reply, /suspend, /unsuspend
  • Push notifications: new order, ticket reply, payment received, service overdue
  • Inline payment buttons - customer pays without leaving Telegram
  • Multi-language: bot follows customer's locale set in WHMCS
  • Per-admin alert channels - sales alerts to one group, abuse to another
  • Markdown-formatted invoice and ticket replies
  • Subscriber linking via one-time code from client area
  • Rate limiting + flood control
  • Webhook + long-poll mode (works behind cPanel firewalls)

Why customers buy this module

  • Customers reply 5-10x faster than email - higher CSAT
  • Admin response time drops because alerts pop on the phone
  • Reduce 'is my server back yet?' tickets - status check is one command
  • Bring offline customers back - renewal nudge in Telegram beats spam-foldered email

Frequently asked questions

Do I need to host a separate Node.js or Python service?

No. The whole bot runs as a WHMCS hook - pure PHP. No extra processes, no extra hosting.

Can I broadcast to all customers?

Yes - admin can compose a broadcast (per language / per product / per group), with rate limiting to respect Telegram's API limits.

What if a customer doesn't use Telegram?

Nothing - email notifications keep working as before. The bot is purely additive.
