Querying for attributes from online feature layer return empty

[JeanYao]

Hi, I am trying to use ArcGIS REST API to query the feature layer attributes by giving a point coordinate and a few parameters in the API. I provided the x,y to Input Geometry parameter, set Geometry Type as "Point", out fields as "*", spatial relationship as "intersects".  The URL after inputting the parameters is below

https://geohub.transport.nsw.gov.au/federated/rest/services/Geohub_Reference/Proposed_Six_Cities/Fea...

More information is it did return records if I input a very large number in the distance parameter. So I think the problem might be the input of spatial reference parameter, hence I tried to use 102100 or 3857 in this parameter, but no records returned. Anything wrong with the parameters?

Thanks in advance for all suggestions.

Thanks to whom for viewing my question. I found the answer now. I should input 3308 to the spatial reference parameter which has been used in our project.
