Signature

Before the API integration, you need to get your AppId and AppKey.

ReelPay API authenticates your requests by AppId and AppKey. Log in to your ReelPay account, go to AppManage page, you can find your AppId and AppKey on this page.

AppId and AppKey carries many privileges, so be sure to keep it secure. Please do not share your developer information in publicly accessible areas such as GitHub, client code, etc.

Signature Algorithm

// sign (golang)
func hmacSHA256Sign(appKey, timestamp string, body interface{}) (string, error) {
   jsonStr, err := json.Marshal(body)
   if err != nil {
      return  "", err
   }
   sha256Mac := hmac.New(sha256.New, []byte(appKey))
   _, err = sha256Mac.Write(append(jsonStr, []byte(timestamp)...))
   if err != nil {
      return "", err
   }
   return hex.EncodeToString(sha256Mac.Sum(nil)), nil
}
