Hello. I have a question.
I want to post json. It contains user information. I want to read the returned Json data.

example url : "api.abc.com/getlist/"

jsoninput = {  
         
              "MERCHANT":"merchid",
              "MERCHANT_KEY":"merchkey",
              "START_DATE":"2022-01-01",
              "END_DATE":"2022-02-02"
           
        }


My Code :

       ServerAdress = "api.abc.com";
Resource = "getlist";
ssl1 = new OpenSSLSecureConnection(Undefined, Undefined);
HTTP = New HTTPConnection(ServerAdress,443,,,,10,ssl1);


HTTPRequest = New HTTPRequest("getlist");
HTTPRequest.Headers.Insert("Authorization", jsoninput);
HTTPRequest.Headers.Insert("Accept",  "application/json");
       HTTPRequest.Headers.Insert("Content-Type","application/x-www-form-urlencoded");
       HTTPRequest.Headers.Insert("Accept-Language",  "en_US");
       HTTPRequest.Headers.Insert("Cache-Control",    "no-cache");
       HTTPRequest.SetBodyFromString("grant_type=client_credentials");
Connection = New HTTPConnection("api.abc.com",,,,,10,New OpenSSLSecureConnection);

       JSONReader = New JSONReader;
 
Try        
           HTTPAnswer = Connection.Post(HTTPRequest); // post Request
           JSONReader.SetString(HTTPAnswer.GetBodyAsString());
       Data = ReadJSON(JSONReader, False);
           message(Data);
       Except
   ErrorText = "Sending " + ErrorDescription();
   message(ErrorText);
EndTry;

Hello Erdoğan,

and what is your question?

I am very sorry. I forgot to write my question. There is an Api service. I want to post a value here. The json information contains login information. Webservice url: "api.abc.com/getlist/". I want to send this as a parameter. I want to read the returned value as json.

jsonparameters= '{
       
              "MERCHANT":"merchid",
              "MERCHANT_KEY":"merchkey",
              "START_DATE":"2022-01-01",
              "END_DATE":"2022-02-02"
         
        }'

Hi Erdoğan Uğuz .
If I understand you correctly you need to put parameters into the request body. But you have another value there.
HTTPRequest.SetBodyFromString("grant_type=client_credentials");
You can do something like this
HTTPRequest.SetBodyFromString(jsonparameters);
Then maybe to add parameter grant_type to your json ?

Hello Erdoğan,

I saw your question on stackoverflow.

Please email me the documentation for this service, and I'll try to help you

Thank you.
I solved the problem.

I fixed the code. Worked.

jsoninput = "{  
         
              ""MERCHANT"":""merchid"",
              ""MERCHANT_KEY"":""merchkey"",
              ""START_DATE"":""2022-01-01"",
              ""END_DATE"":""2022-02-02""
           
        }";

HTTPRequest.SetBodyFromString(jsoninput);

Hello Erdoğan,

as I understand it, you had a problem with the creation of JSON. You create it manually now. But try the following code:

Procedure createParameters()

   merchid = "merchid";
   merchkey = "merchkey";
      
   structureParameters = New Structure;
   
   structureParameters.Insert("MERCHANT",       merchid);
   structureParameters.Insert("MERCHANT_KEY",    merchkey);
   structureParameters.Insert("START_DATE",    "2022-01-01");
   structureParameters.Insert("END_DATE",       "2022-02-02");
   
   resultJSON = toJSON(structureParameters);

EndProcedure

Function toJSON(Value)
   
   JSONWriter = New JSONWriter;
   JSONWriter.SetString();
   
   WriteJSON(JSONWriter,Value);
   
   Return JSONWriter.Close();
   
EndFunction

1C has good tools for working with JSON and it is more convenient to use them than to create JSON manually every time.

And the probability of error in this case is much lower.
