sign
string
requestBody
required

Every API request must be signed so that we can identify your account.

The signature is transferred in the request body through the sign parameter, for example:

{
    "shop_id": 1520,
    "shop_order_id" : "5b0efa8a-153b-4421-abac-2aba4d772a86",
    "amout": "6320.91",
    "currency": 840,
    "payway": "card_invoice_usd",
    "description": "Payment for shop_id=1520",
    "sign": "77a6f7a30876d480d4e771d08cb83800dd5cb874664c77e515ffc052b20293c6"
}
All further request examples do not include the "sign" parameter, nevertheless your real requests must include it in the request body where required.

Signature line is generated according to the following algorithm: all request parameters involved in signature generation are ordered in the alphabetical order of keys, the values are concatenated with a colon (":") and the account secret key is added at the end (without the: sign), a sha256 hash is generated from the resulting line and its hex representation is passed in the sign request parameter.

Example of signature generation for a method invoice/create:

  1. Determining the list of parameters. It looks as follows for the method in consideration:

Fields involved in request signature generation:

  • shop_id
  • shop_order_id
  • amount
  • currency
  • payway
  1. Let's sort keys in alphabetical sequence:

"amount", "currency", "payway", "shop_id", "shop_order_id"

  1. The line for generating the SHA256 hash will be as follows:

"6320.91:840:card_invoice_usd:1520:5b0efa8a-153b-4421-abac-2aba4d772a86account-secret-key"

Where account-secret-key is the secret identification key for your account. You can request a key from the support service.

  1. Let's get a hash expression of the generated line using Python code:
>>> string_to_sign = '6320.91:840:card_invoice_usd:1520:5b0efa8a-153b-4421-abac-2aba4d772a86account-secret-key'
>>> import hashlib
>>> sign = hashlib.sha256(string_to_sign.encode()).hexdigest()
>>> print(sign)
'77a6f7a30876d480d4e771d08cb83800dd5cb874664c77e515ffc052b20293c6'
You can check whether you have generated the signature correctly using the service https://www.xorbin.com/tools/sha256-hash-calculator.
