Authentication

This API uses JSON format for receiving request bodies and passing responses.

This API uses RSA signatures (passed in x-sign header) to verify the origin of request. Sign is generated with request body, encrypted in base64 and verified the same way. Contact our support providing your RSA public key to obtain access to this API.

Generating signatures

Signature generating algorithm - SHA-1
Preferred key: encrypted by password 2048 bit length

// You can get a simple private/public key pair using:
// openssl genrsa 512 >private_key.txt
// openssl rsa -pubout <private_key.txt >public_key.txt

// IMPORTANT: The key pair below is provided for testing only.
// For security reasons you must get a new key pair
// for production use, obviously.

// IMPORTANT: When converting data into JSON in PHP,
// pay attention to the use of JSON_UNESCAPED_UNICODE flag.
