Once shkeeper.io receives a payment it will send a payment notification to the <callback_url> using POST with json-encoded body and X-Shkeeper-API-Key HTTP header to authenticate to your system:

{
  "external_id": "1",  // Invoice or Order ID in the external system
  "crypto": "BTC",  // crypto currency (provided during payment request creation)
  "fiat":   "USD",  // fiat currency (provided during payment request creation)
  "balance_fiat":      "100",  // amount in fiat currency
  "balance_crypto": "0.0025",  // amount in crypto currency
  "paid": true,  // true  -- if the payment request is fully paid
                 // false -- when only a partial payment received
  "transactions": [  // list of transactions related to the payment request
    {
      "txid": "ZZZZZZZZZZZZZZZZZZZ",  // blockchain transaction ID 
      "date": "2022-04-01 11:22:33",  // transaction date
      "amount_crypto": "0.0025",      // transaction amount in crypto currency
      "amount_fiat": "100",           // transaction amount in fiat currency
      "trigger": true,  // true -- if this transaction was a trigger for payment notification
    },
    ...
  ]
}

If a payment notification was successfuly processed by your server, it should return HTTP code 202 Accepted. Any other response or connection failure will cause shkeeper.io to send a payment notification again in 60 seconds.
