How to use a custom service with JSON input via POST

[njourdan]

Hello everybody,

I created a custom service with a JSON Input called "Data". I am trying to test this service via Postman.

Data will contain something like this:

[

{

"var1":5,

"var2":10

},

{

"var1":5,

"var2":10

}

]

Can someone tell me how i correctly pass this to Thingworx? So how do i have to format my body in postman? And in Thingworx Javascript do I have to parse the json first or is it already passed as i specify the input as json.

Thanks. I think the documentation on these things is really sparse

Hi Nicolas Jourdan​,

tl;dr

To make it easy - if you need to pass an array in a format of JSON, just add a JSON type input parameter e.g. "data".

This array can be accessed by refering to "array" property, e.g.:

data.array.length;
data.array[0];
data.array[0].var1;
data.array[1].var2;

To pass that data from Postman or other tool, you need to pass as a body of the POST request:

{
     "data": [
          {
               "var1": 1,
               "var2": 2
          },
          {
               "var1": 3,
               "var2": 4
          }
     ]
}

Please, remember to set a Header Content-Type: application/json and authorize with Application Key. If you expect any response, you can also set a Header Accept: application/json (if this format fits you).

Hope this helps.

J.
