Using MercadoPago Payment

Searching:

// Sets the filters you want
Map<String, Object> filters = new HashMap<String, Object> ();
   filters.put("site_id", "MLA"); // Argentina: MLA; Brasil: MLB
   filters.put("external_reference", "Bill001");
        
// Search payment data according to filters
JSONObject searchResult = mp.searchPayment (filters);
JSONArray results = searchResult.getJSONObject("response").getJSONArray("results");

for (int i = 0; i < results.length(); i++) {
	System.out.println(results.getJSONObject(i).getJSONObject("collection").getString("id"));
	System.out.println(results.getJSONObject(i).getJSONObject("collection").getString("external_reference"));
	System.out.println(results.getJSONObject(i).getJSONObject("collection").getString("status"));
