Fetching data from external REST API/websockets

[Sri1]

I wanted to set the position(Lat-Lng) properties of a Thing,  by fetching data from an external Rest APT/Websockets.

I want this process to be continues.Where and how can we achieve this?( Through Events or Services or Subscriptions)

You could use Services->Snippets->Resources->ContentLoaderFunctions( e.g GetJSON) to make the REST call. This service could then be called from a Subscription which in turn would be triggered by a Timer Event(emitted by a thing implementing Timer Thing Template), to have this call made periodically.

Hi rjanardan,

I wrote a service for REST API fetch at the location specified by you.

I am new in thingworx programming,

 1) How do i call this service to check my code.

 2) How do i call this service from the subscription.

3) Is there any example or tutorial link that i can go through, to successfully follow the steps you have provided.

Thanks and regards,
