I have enabled webhook on Shopify. Shopify sends raw JSON in webhook response. Somehow it is converted to map and now I want to convert it back to raw JSON that Shopify sends for HMAC verification. Can someone help how it can be done in JAVA? What encoding is applied to data at Shopify end? 

Shopify Webhook JSON:

HMAC verification code is correct. The problem is with the webhook body. I want to convert JSON to its original format that Shopify sends in the webhook

Serializing Map to JSON is a very simple task in Java. You may use any of JSON libraries, the most popular are Json Jackson (also known asFaster XML) or Gson of Google. But if you want even simpler solution, I wrote my own thin wrapper over Jackson Json that allows you to serialize an object to JSON or deserialize it from Json to Object. For your case the code could be as simple as this

Map<String, Object> map = ... //here is your map that you got from your source
String jsonString;

    try {
      jsonString = JsonUtils.writeObjectToJsonString(map);
    }catch(IOException ioe) {
      //Handle exception
    }

Here is the Javadoc for JsonUtils class. It is part of MgntUtils open source library written and maintained by me. You can get the library as maven artifact here or from Github, including source code and Javadoc here

user_58024170 
Map<String, String> elements = new HashMap();
elements.put("Key1", "Value1");
elements.put("Key2", "Value2");

ObjectMapper objectMapper = new ObjectMapper();

try {
    String json = objectMapper.writeValueAsString(elements);
    System.out.println(json);
} catch (JsonProcessingException e) {
    e.printStackTrace();
}
