# Vero

## Docs

- [API Reference](https://docs.veroreceipts.com/api-reference/introduction.md): The Vero API enables secure, encrypted receipt transmission between merchants, card issuers, and end users. All APIs use RESTful principles with JSON payloads and industry-standard authentication.
- [Grant Decrypt Access](https://docs.veroreceipts.com/api-reference/keys/grant-access.md): Issue a short-lived access token (2-3 minutes) for receipt decryption. The source IP is logged for audit purposes. Maximum 5 active tokens per user.
- [Generate Key Pair](https://docs.veroreceipts.com/api-reference/onboarding/generate-keys.md): Generate an RSA-2048 key pair for a new user. The private key should be securely stored by the client and never transmitted again after this response.
- [Register User](https://docs.veroreceipts.com/api-reference/onboarding/register.md): Register a new user with their hashed PAN and public key. The hashed PAN is a unique identifier derived from the user's Primary Account Number. The public key must be from a previously generated key pair.
- [Create Payment](https://docs.veroreceipts.com/api-reference/payments/create.md): Create a payment (Stripe/Square) with encrypted receipt metadata. This endpoint encrypts the receipt, creates a payment intent/order on the gateway, and attaches Vero metadata for later retrieval.
- [Decrypt Receipt](https://docs.veroreceipts.com/api-reference/payments/decrypt.md): Decrypt a receipt by looking up the payment transaction on the gateway (Stripe/Square). Requires a valid access token and the user's private key.
- [Encrypt Receipt](https://docs.veroreceipts.com/api-reference/receipts/encrypt.md): Encrypt a digital receipt for a specific recipient using hybrid encryption: - AES-256-GCM for the receipt data (symmetric) - RSA-OAEP-SHA256 for key wrapping (asymmetric)
- [Sequence Diagram](https://docs.veroreceipts.com/api-reference/sequence-diagram.md): The full flow of Vero, from payment intent, to viewing the receipt in your card issuer app.
- [Technical Flow](https://docs.veroreceipts.com/api-reference/technical-flow.md): Step-by-step API integration guide with request/response examples. Copy values from each response to use in subsequent steps.
