Integration in Business Central & Read JSON Data and store in Table : Using Http

Hi Readers,

In this article will see how we can create connection with external application using  HTTP and read the Json data & store it in business central.

In this scenario, if i will enter the ID then it will fill all the related details by getting information from third party application.

Step-(1) Firstly i have created the table and call the procedure on OnValidate trigger.

table 50102 "User Details API"
{
    DataClassification = ToBeClassified;

    fields
    {
        field(1; ID; Integer)
        {
            DataClassification = ToBeClassified;
            trigger OnValidate()
            var
                JsonReadAndWrite_CU: Codeunit "Json Write";

            begin
                JsonReadAndWrite_CU.JsonReadAndWrite(Rec);
            end;
        }
        field(2; Name; Text[50])
        {
            DataClassification = ToBeClassified;
        }
        field(3; "User Name"; Text[50])
        {
            DataClassification = ToBeClassified;
        }
        field(4; "Email"; Text[50])
        {
            DataClassification = ToBeClassified;
        }
        field(5; "Street"; Text[50])
        {
            DataClassification = ToBeClassified;
        }
        field(6; "Suite"; Text[50])
        {
            DataClassification = ToBeClassified;
        }
    }

    keys
    {
        key(PK; ID)
        {
            Clustered = true;
        }
    }
}

Step-(2) Then i have created the page which basically used to interact with user & see the output.

page 50103 "User Details API"
{
    PageType = List;
    ApplicationArea = All;
    UsageCategory = Lists;
    SourceTable = "User Details API";

    layout
    {
        area(Content)
        {
            repeater(List)
            {
                field(ID; ID) { ApplicationArea = All; }
                field(Name; Name) { ApplicationArea = All; }
                field("User Name"; "User Name") { ApplicationArea = All; }
                field(Email; Email) { ApplicationArea = All; }
                field(Street; Street) { ApplicationArea = All; }
                field(Suite; Suite) { ApplicationArea = All; }
            }
        }
    }
}

Step-(3) Now finally i have create a function which makes the connection using HTTP and get data from external application & store in Business Central table.

 Procedure JsonReadAndWrite(Var UserDetailsAPI: Record "User Details API")
    var
        UrlPath: Text;
        HttpClientVar: HttpClient;
        HttpResponseVar: HttpResponseMessage;
        HttpContentVar: HttpContent;
        Result: Text;
        //Method2
        HttpRequest: HttpRequestMessage;
        Output: Text;
        JObject: JsonObject;
        JToken: JsonToken;
        NewJObject: JsonObject;

    begin
        UrlPath := 'https://jsonplaceholder.typicode.com/users/' + Format(UserDetailsAPI.ID);
        HttpClientVar.Get(UrlPath, HttpResponseVar);
        if HttpResponseVar.IsSuccessStatusCode then begin
            HttpContentVar := HttpResponseVar.Content;
            HttpContentVar.ReadAs(Result);
            // Message(Result);

            //To store the content in Json Object
            JObject.ReadFrom(Result);
            JObject.Get('name', JToken);
            UserDetailsAPI.Name := JToken.AsValue().AsText();
            JObject.Get('email', JToken);
            UserDetailsAPI.Email := JToken.AsValue().AsText();
            JObject.Get('username', JToken);
            UserDetailsAPI."User Name" := JToken.AsValue().AsText();
            JObject.Get('address', JToken);
            if JToken.IsObject then begin
                JToken.WriteTo(Output);
                NewJObject.ReadFrom(Output);
                NewJObject.Get('street', JToken);
                UserDetailsAPI.Street := JToken.AsValue().AsText();
                NewJObject.Get('suite', JToken);
                UserDetailsAPI.Suite := JToken.AsValue().AsText();
            end else
                Message('Json Token is not found as Json Object.');

        end else
            Message('Connection not Established..Status Code is %1 & Reason is %2', HttpResponseVar.HttpStatusCode, HttpResponseVar.ReasonPhrase);
    end;

Output:-

Inv. Header (122) Gen. Journal Line (81)  G/L Entry (17) For the Purch. Inv. Header table, you can just create copy the field from purchase header and paste it in  Purch. Inv. Header  table. If the field ID No. is same for that field for both the tables then you don't have to code i.e, it automatically transfer that field data from Purch. Header to Purch. Inv. Header .
