Adding feature with geographic coordinate

HN1

Hi !

I am quite new to use REST API and trying to add point feature to my feature service right now.

I successfully added features but locations were very different from where I expected.

My data has only geometry in latitude and longitude, so I suppose what I need to do is transform lat, lon values to web mercator projection before adding data.

My question is that;

1) Can I specify spatial reference in add feature operation?

2) If I cannot specify the spatial reference in the operation, how can I transform lot & lon to web mercator coordinate values via REST API before add data?

If this kind of question was solved before, please suggest URL for the thread.

Thank you!

Try using "projectAs" as illustrated in line 11 below.  A bit more of this example is shown here.
