Bulk procurement

Submit hundreds of stamps in one call. Two-phase validate-then-commit with per-row errors and a price quote.

Prepaid wallet

Fund a pass-through stamp-duty wallet by NEFT — no GST on funding. Holds and debits from an append-only ledger.

Signed webhooks

stamp.verified, order.fulfilled, wallet.low_balance — signed with Standard Webhooks and full delivery log.

Sandbox + live keys

Build against isolated sandbox with sk_test_ keys, then flip to sk_live_. Idempotent, stable error envelope.

How it works

Three steps to production

1
Fund your wallet
Transfer stamp duty by NEFT; we credit your prepaid wallet (no GST).
2
Submit stamps
Validate + create a bulk order; we allocate to vetted partners.
3
Receive & reconcile
Get verified stamps + certificates, webhooks, and an audit register.
