NOWPayments

NOWPayments takes payment in a long list of coins. The buyer picks the coin on the NOWPayments page. It is the one gateway switched on in the shipped config.yml, waiting for its keys.

Setup

nowpayments:
  enabled: true
  icon: GOLD_INGOT
  currency: ""
  # NOWPayments API key from your dashboard
  api-key: "..."
  # IPN secret used to verify webhook signatures
  ipn-secret: "..."
  # Use the NOWPayments sandbox API instead of live
  sandbox: false
  # Restrict payment coins, for example ["btc", "eth", "ltc"]. Empty lets the buyer pick any
  accepted-currencies: []

Good to know

• accepted-currencies with exactly one coin locks every invoice to that coin. With two or more, NOWPayments cannot lock an invoice to a list, so restrict the coins in your NOWPayments dashboard instead (the console reminds you).
• Coin minimums are set by NOWPayments per coin and shown on its page.
• Short payments (partially_paid) and extra deposits on an old payment go to Needs review.
• Lookups only work once the buyer has picked a coin. An order nobody started paying waits for its webhook or expires.
• NOWPayments keeps a payment open for 7 days. A payment after Emberstore expired the order goes to Needs review.
• Refunds are done by hand. NOWPayments has no refund API. /store admin refund marks the order refunded, takes the reward back and tells you to send the coins back from the NOWPayments dashboard. Emberstore never moves crypto for you.
• Sandbox payments report nothing paid. In the sandbox a finished payment shows 0 as the amount paid, so with sandbox: true Emberstore skips the short payment check. The check is always on against the live API.
