Json Format ( POST/PUT REST API )

[Aymen1]

Hello team,

I am a beginner with talend and I am looking to do a POST of this Json format

{

    "data": [

        {

           "a": 46302,

            "b": 816768,

            "c": "5.000000"

    }

      ]

}

How can I have this format with tWriteJsonField component ?? -- my message error : {"code":404,"message":"Json invalide"}

 

In advance, thank you for your answer .

I have the solution, with each json extract component write the "json looppath querry" like this "$" and you will access the next element in the tree, ie you will get more details. then at the end, in the component "json extract" same thing but for the fields write the final fields of the json object like this "$ .id" "$ .name" "$ .firstname"
