Payments in chat, never charged twice.

We build payment flows that live inside Telegram: invoices, checkouts, subscriptions and payouts, in crypto or through Razorpay, UPI and cards. Every payment is verified, recorded and reconciled.

Every way your customers pay

  • Crypto invoices — on-chain payments with automatic confirmation.
  • Razorpay — cards, UPI and netbanking for customers in India.
  • Subscriptions — renewals, expiry and grace periods handled, not assumed.
  • Payouts — sending money out as reliably as taking it in.

Built so money never goes missing

  • Every callback’s signature is checked; unsigned callbacks are dropped.
  • Settlement is idempotent, so a retried or duplicated webhook can never charge twice.
  • Each attempt is one row in a ledger: the record of what actually happened.
  • A daily reconciliation compares our totals with the gateway’s, line by line.

What happens after payment

Access unlocks the moment a payment confirms. Our own sale bots go further: they reserve stock when an invoice is raised, release it if the invoice expires, and deploy the customer’s service automatically once the money arrives.

Questions

Asked and answered.

Which payment gateways can a Telegram bot use?

We integrate crypto payment gateways, Razorpay for cards, UPI and netbanking, and other card processors, depending on where your customers are.

What if a payment webhook arrives twice?

Nothing happens the second time. Settlement is idempotent, so duplicates and retries can never charge a customer twice.

Can a payment unlock access automatically?

Yes. Access, subscriptions or even a full deployment can start the moment a payment confirms.
