Hello,
New to using web services here. I am trying to use oauth2 login to Portal ArcGIS Server feature service on a specific layer index and use the REST Query function to pass in a couple of parameters and then have the output to json format.
For instance this is the ArcGIS Server Feature Service on a particular feature layer (e.g. index 3) https://ppp-snoopy.com/un/rest/services/SnoopyUN_Network/FeatureServer/3
Then pass in the string query parameters according to this reference page Query (Feature Service)—ArcGIS REST APIs | ArcGIS Developers
where: GUID = 'abc1234xyz'
gdbVersion : Snoopy.Survey
outfields : objectid, GUID
f: json
I am trying use HTTP Caller to access the ArcGIS Server feature service using NTLM authentication and got this error :
{"error":{"code":499,"message":"Token Required","details":&]}}
I also tried to use direct URL to the ArcGIS Server Feature Service (without Portal) and no luck.
Any help would be appreciated!
Thanks!
