Layer's data sniffer

[VasylynaMykhalchuk]

Hello everybody! 
I have an issue with retrieving data from feature layer at map service that hosted on ArcGIS Server. Can I make programmatic sniffer of feature layer's data (coordinates of polygons is the most important part) at JSON format? 

Any help is appreciated!

Vasylyna,

   Are you using a certain API for this like JS API or are you talking about doing this purely through the REST service api? This information will help in proper placement of you question. Right now you are asking this question in the General GeoNet Community Help Space.

I'm talking about to do this using REST service API and then visualize data from response at map using JS API

Vasylyna,

OK I will move this to the JS API space on GeoNet.

You should look at this JS API Sample:
