An example of the formation of a digital signature on PHP
                                     
function getFormSignature($id, $currency, $amount, $external_invoice, $secretKey) {
 $hashStr = $id.'{up}'.$currency.'{up}'.$amount.'{up}'.$external_invoice.'{up}'.$secretKey;
 return hash('sha256', $hashStr);
}

$signature = getFormSignature($id, $currency, $amount, $external_invoice, $secretKey);
The digital signature is formed as sha256 (payment initialization parameters described above with the addition of secretKey = ACCESS KEY from the settings of the payment merchant). When forming a digital signature, all the variables shown in the example must be indicated.
Example
https://cryptokick.app/api/merchant.php?
act=request_payment
test=Y
form=Y
coin=BTC
id=Identifier from payment merchant settings
amount=0.01
currency=BTC
external_invoice=1000
message=Test Invoice
signature=Digital signature
callback_url=http://example.com/pay.php

Test mode

If the parameter value is test = Y, then the query is executed in test mode. The invoice will have the status Paid without actual payment and payment being credited. Notification of payment by e-mail is not sent. If the handler URL (parameter callback_url) is passed, the result will be sent to it.

Output result

If the value of the parameter form = N, then the result of the generated payment is displayed in JSON format for further processing.

Parameter Value Description
amount Integer Payment amount in the selected cryptocurrency
invoice Integer Internal account number used in the system
external_invoice String External account number used in your store
link String Payment Link
address String Generated Wallet Address
message String Description of the account that was transmitted during account generation

Payment processor

Upon receipt of payment by invoice, we notify the store’s website of the payment status by sending a GET request to the handler URL (callback_url parameter).
Parameter Description
id Identifier from payment merchant settings
key Confirmation key from payment merchant settings
coin Which cryptocurrency paid the bill
currency In which currency is the account generated according to ISO 4217
invoice Internal account number used in the system
external_invoice External account number used in your store
amount Amount of payment received
amount_in_currency Account amount in the currency of the generated account
message Description of the account that was transmitted during account generation
signature Digital Signature Generated
An example of the formation and verification of a digital signature on PHP
                                   
function getSignature($id, $currency, $amount_in_currency, $external_invoice, $secretKey) {
 $hashStr = $id.'{up}'.$currency.'{up}'.$amount_in_currency.'{up}'.$external_invoice.'{up}'.$secretKey;
 return hash('sha256', $hashStr);
}

$signature = getSignature($_GET["id"], $_GET["currency"], $_GET["amount_in_currency"], $_GET["external_invoice"], $secretKey);

if ($_GET["signature"] != $signature) exit('Incorrect Digital Signature');
In the payment processor, you must generate a digital signature using the received variables and verify it against the received digital signature. For the secretKey value, use the ACCESS KEY from the payment merchant settings.

Payment alert response format

Applicable if the processor URL is specified during the formation of the payment (parameter callback_url)
As a result of processing a GET request containing payment data, the store’s website should return a response with the code 200 as a string:
  • The answer is equal to the line \ok\ - this means that payment data has been received, notifications for this payment are no longer required.
  • Any other answers - this will mean that the store has not received data and the store will continue to be notified.
Note: the maximum number of alerts to receive a successful response from the store website:
Note: a retry alert will be attempted every 5
If the answer is not equal to the string \ok\, the first 255 characters of the store’s response to the request will be saved and available for viewing in your account.
Note: if the request is executed in test mode and the payment notification failed, the response code and response line will be available for viewing on the bill payment page. To view, click on the recipient notification status. In normal mode, only status is displayed.
