Add Feature Polygon via REST API

lougalban — Wed, 11 Aug 2021 20:28:01 GMT

I'm trying to add a feature layer via REST API, but its not working. I only have 4 corners coordinates. Below is my code.

'geometry' => [ 'hasZ' => false, 'hasM' => false, 'rings' => [[[121.458756,15.807697],[121.458784,15.807773],[121.459115,15.807692],[121.459088,15.807596],[121.458756,15.807697]]], 'spatialReference' => [ "wkid" => 4326 ] ]

Any idea?

which api is this? I don't get the syntax =>

Shouldn't rings be closed off with a repeat of the initial vertex? Do you have a reference to where you've got this from?

Hi thank you for the response, I'm very new to ArcGIS. It was close, first and last is same coordinates.. Did I do it wrong?

This is my reference:

You need to create a properly formatted JSON feature object.

It would look something like:

[{ "geometry": { "rings": [ [ [121.458756, 15.807697], [121.458784, 15.807773], [121.459115, 15.807692], [121.459088, 15.807596], [121.458756, 15.807697] ] ], "spatialReference": { "wkid": 4326 } } }]
