## What it does

The server gives an agent tools to create payment orders and email customers a payment link. It can look up a payment by Flow token, Flow order number or your `commerceOrder`, list payments for a date, and start a full or partial refund. Customers pay on Flow’s hosted page, which supports Webpay, ETpay, cash networks and international cards.

Set `FLOW_API_KEY` and `FLOW_SECRET_KEY` to authenticate requests. The server creates the HMAC-SHA256 signature; the secret key stays off the wire. `FLOW_ENV` selects the environment, with `sandbox` as the default. Flow provides a separate key pair for sandbox use, so production credentials won’t work there.

## Requirements
- Needs: Node.js (commands run via npx)
- Environment variables: `FLOW_API_KEY`, `FLOW_SECRET_KEY`, `FLOW_ENV` — keys and tokens: ask the human for the values, never commit them or put them in shared files.
