    Problems with WSEMS and posting REST API calls.

    Hi everyone,

     

    I am having trouble managing to set multiple properties of a single thing on the platform with one single REST call. I am using CURL to manually send the REST call, pointing to WSEMS which is running on the same machine. When I try something like that:

     

    curl -vvv -X PUT --data '{"histogram0":572,"histogram1":243}' -H "Content-Type:application/json" http://localhost:8000/Thingworx/Things/Sensor001/Properties/histogram1

     

    it only updates the histogram1 property and not the histogram0 one as well, as included in the JSON. If I try omitting histogram1 from the URI, it gives me an error. Is it not possible to update more than one property at a time with one REST call in this way, or would I need to call the UpdatePropertyValues service from my REST call like so?

     

    curl -vvv -X PUT --data '{"name":"histogram0","value":572,"timestamp":150000000,"quality":"GOOD"}' -H "Content-Type:application/json" http://localhost:8000/Thingworx/Things/Sensor001/Services/UpdatePropertyValues

     

    Here, just as a first step, I only give it one property update. However, the above doesn't seem to work either. Can anyone share their wisdom regarding this?

        Hi Marios, in your first REST call, not sure if its complete, but you seem to be updating only histogram1 property as your REST call is only setting /Sensor001/Properties/histogram1 i think this is why you also get error when you only try to update hsitogram0 with that call. Did you try switching it to "*"

        Something like .../Sensor001/Properties/*


        What exact error do you receive for 2nd REST call? Could suggest to use Postman to formulate right REST calls, makes debugging easier


        Edit:


        Not sure if you have already seen this, but there are some nice explanation and examples in this blog REST API Overview and Examples
