    Common information


    Request Header

    x-ncp-apigw-timestamp- It is the number of milliseconds that have elapsed since January 1, 1970 00:00:00 UTC.
    - If the time difference with the API Gateway server is more than 5 minutes, the request is considered invalid.
    x-ncp-iam-access-keyAPI key issued by NAVER Cloud Platform or access key issued by IAM
    x-ncp-apigw-signature-v2- Signature used to encrypt the body of the example with the “secret key” that maps with the “access key.”
    - The HMAC encryption algorithm is HMAC SHA256.

    Error code

    If a wrong API request is sent, or an error occurs during its processing, then the success/failure result is returned as an HTTP status code. The detailed message is then returned in the form of JSON/XML.

    Response example

       "returnCode":"Return code",
       "returnMessage":"Return message"

    If the output format is XML

      <returnCode>Return code</returnCode>
      <returnMessage>Return message</returnMessage>
