Authentication

The authentication process is carried out by sending 2 HTTP headers:

Name	Definition
merchant	The merchant's uuid, which you can find in the merchant's personal account in the settings section.
sign	MD5 hash of the body of the POST request encoded in base64 and combined with your API key.

Definition The merchant's uuid, which you can find in the merchant's personal account in the settings section.
Definition MD5 hash of the body of the POST request encoded in base64 and combined with your API key.

Example of signature generation in php:


$data = json_encode($data);
$sign = md5(base64_encode($data) . $API_KEY);

Copy

If the request doesn’t require passing parameters in the body, then form a signature for an empty string:


$sign = md5(base64_encode('') . $API_KEY);

Different Key APIs are used to accept payments and payouts
