To active the Yandex.Money service and send requests, you need a special certificate (for more information, see the certificate exchange procedure).
The Counterparty's system and the Yandex.Money server interact over the HTTPS protocol. For each operation, the Counterparty sends a separate HTTP request containing a PKCS#7 cryptographic message. Yandex.Money responds to each request for deposit with a message about the result of the operation included in the PKCS#7 cryptographic message.
The communication channel is also cryptographically secured using the SSL (HTTPS) protocol with client certificate authentication. In addition, there is a restricted list of IP addresses that can send requests to the Yandex.Money server.
Forming a request to the server includes several steps.
Server address for calling operations
Test server: https://bo-demo02.yamoney.ru:9094/
Real server: https://calypso.yamoney.ru:9094/
The prepared document is placed in a PKCS#7 cryptographic message container according to the CMS standard. The cryptographic message container must contain a digital signature (equivalent to a handwritten signature). The cryptographic message container must not contain certificate authority chains. Data compression is not used. Encryption is not used. The cryptographic message must be encoded in PEM format (OpenSSL). The certificate of the Counterparty that is used for preparing the cryptographic message must conform to the X.509 Version 3 standard.
To authorize requests to the server, Yandex.Money verifies the digital signature on the cryptographic message.
To avoid repeating deposits accidentally, each operation is assigned a unique number (clientOrderId).

The result of request execution is returned by Yandex.Money in the response to the HTTP request. MIME type: application/pkcs7-mime. Data is placed in a PKCS#7 cryptographic message container. The cryptographic message container contains a digital signature (equivalent to a handwritten signature). The cryptographic message container does not contain certificate authority chains. Data compression is not used. Encryption is not used. The cryptographic message is encoded in PEM format (OpenSSL). The cryptographic message container contains an XML document with the result of request processing.
When receiving the server response, the Counterparty's system checks the signature on the response to verify that the response was sent by the Yandex.Money server and its content was not altered by a third party. Note that the response may include additional fields not described in this protocol that do not interfere with compatibility.
