Hi,

Below is my JSON data format from my IoT device. We can't change below JSON string format. When I pass this String to TWX it shows error in JSON String format. Help me to fix this. Thanks in advance.

{

"PE":128,

"UID":"WISE-4051_00D0C9CC0077",

"MAC":"00-D0-C9-CC-00-77",

"TIM":"1480322199",

"Record":[[0, 1, 1,  0],[1, 1,32,    0],[1, 1,33, 17]]

}

Hey Velkumar,

I was just able to consume this json message  correctly in thingworx. Can you test the following steps and tell me what your results are?

- Create a thing in Thingworx called JsonTestingThing based on a GenericThing

- Create a service with an input of type JSON called json

- Set the output type to JSON

- the code should be:

     result = json;

Now, execute this service via cURL or postman:

curl -X POST -H "apiKey: [API KEY HERE]" -H "Content-Type: application/json" -H "Accept: application/json" -H "x-thingworx-session: true" -d '{

"PE":128,

"UID":"WISE-4051_00D0C9CC0077",

"MAC":"00-D0-C9-CC-00-77",

"TIM":"1480322199",

"Record":[[0, 1, 1,  0],[1, 1,32,    0],[1, 1,33, 17]]

}' "[THINGWORX URI HERE]/Thingworx/Things/JsonTestingThing/Services/test?postParameter=json"

Thanks

    I verified James McCuen​ 's results with POSTMan. Here's my service:

    Here's my POSTMan POST. Note - I'm using POSTMan environment variables. That's where the {{protocol}}, {{host}}, ... stuff comes from.
