    Unified API Request Parameters

    Content#

    ParameterRequiredTypeDescription
    appIdYesstringMerchant APP ID, provided by Platform
    signYesstringRSA signature of param
    paramYesstringRequest parameter string

    Example#

    {
    "appId": "123456",
    "sign": "abcdef",
    "param": "{}"
}

    Description#

    1.
    appId is a fixed value provided by Platform;
    2.
    Construct request parameters according to specific API documentation, format them as JSON, and use as value of param;
    3.
    Use RSA private key to sign param, and use the result as value of sign.

    Appendix RSA Usage Example (Java)#

    Generate RSA key pair:
    Please submit RSA public key to Platform, do not disclose to any third party.
    RSA private key is kept by merchant, do not disclose to anyone.
    When merchant requests Platform's Open API, merchant uses RSA private key to sign request parameters, Platform will use merchant's RSA public key to verify the signature in the request. If verification fails, Platform server will reject the request.
