Instant Voucher Code Verification in Telegram

Customer says 'Is code XYZ123 valid?' Tap a button and Notis checks Piggy instantly, showing status and remaining uses. No manual verification, no confusion.

Trigger

Callback Query Received

Triggered when a user taps an inline keyboard button attached to one of your bot's messages.

Action

Find Voucher By Code

Tool to find a voucher by its unique code. Use when you need to retrieve voucher details, check redemption status, or validate a voucher code.

Why this helps

Without quick verification, customers wonder if codes are legit, or founders waste time looking up codes instead of focusing on business.

  • Customers get instant code validation without waiting
  • Prevents invalid or expired code redemptions
  • Eliminates manual founder lookups

Setup

Build it in a few focused steps.

  • 1Connect Telegram and Piggy to Notis
  • 2Create an automation named 'Validate voucher codes' with this instruction: 'When a customer asks if a voucher code is valid or taps a validation button, check Piggy and reply with the code status, uses remaining, and expiration date'
  • 3Select the trigger: Callback Query Received in Telegram
  • 4Add a 'Validate code' button to your messages (Notis provides the template)
  • 5Test by having someone tap the button with a known voucher code

Questions about this workflow

What if the code doesn't exist?

Notis will reply that the code isn't found and suggest they check spelling or contact support.

Can I show redemption history for the code?

Yes. Specify in your instruction 'show how many times it's been used and who used it' if you want that level of detail.

Does this prevent redemption or just show the status?

This is verification only. It shows status and details but doesn't redeem. You handle redemption separately based on the validation.
