Question in the title. I've been searching high and low, and I cannot find a comprehensive list of all variables available to use with the /Enrich endpoint. I don't want to manually search for variables in the variable finder tool. I want a complete list or every variable that can be used to enrich an area. ... View more

I've been struggling to find documentation for my exact use case, and I was hoping someone here can point me in the right direction. I have a feature layer (which is not shared publicly) in ArcGIS Online, which I want to share with a client so that it can be displayed and queried on a map within their application. The client's application is not public, and is secured using their own authentication. They do not want the users of their app to see a second ArcGIS username & password prompt when the map loads the layer, nor do I want to provide them with a user name and password for our AGOL organizational account. I want to provide them with an API key, OAuth credentials, or implement some other authentication scheme so that their developers can add a map to their app, using the ArcGIS JavaScript SDK, which shows the layer I want to share with them, allowing the developers to handle authentication without any need for username and password input from the user. I have been reading through the ArcGIS documentation on authentication for OAuth2 and API keys, but I can't seem to find anything pertaining to this exact workflow. Is this even possible? If so, is anyone aware of relevant documentation from Esri on how to do this? ... View more

I recently started exploring the Flask web application framework for Python, but I ran into an issue when trying to deploy the application to Windows Server. My Flask application had a dependency on arcpy, which was available on my local development environment, but not on my server. As you are likely aware, the arcpy package is not available outside of the ArcGIS Pro Python environment, and I ran into quite a few issues with not being able to import and use these libraries. After some some googling, lots of trial and error, and a little help from Esri support, I was able to accomplish this task! https://mfcallahan.com/2025/02/17/deploying-a-python-flask-application-which-can-import-arcpy-and-the-arcgis-python-api-to-windows-server/ Above is the link to my blog post which goes into deep detail on how to accomplish this, but at a high level, the steps needed to accomplish this are: Copy app code to server Clone the default "arcgispro-py3" environment Activate your cloned ArcGIS Pro Python environment in Conda Install the flask and wfastcgi dependencies Copy file "wfastcgi.py" to the root app folder from the Python site-packages folder Create a new application pool Set app folder ownership to IIS AppPool Add app to FastCGI Server Settings, using the cloned Python env Set <handlers> in web.config file ...

I have a PostgreSQL database instance running in the Azure Database for PostgreSQL service. I am able to successfully connect, create enterprise geodatabases within, and load feature classes. I am also able to register the database as a data store, both via ArcGIS Pro and ArcGIS Server Manager. However, when attempting to share a table in the database as a web layer (right click > Sharing > Share as web layer), it will ultimately fail with error 00231, "Layer's data source must be registered with the server." seemingly not recognizing the registered data store I had just added. I verified there were no typos or other configuration errors.   Tech support provided the following guidance, which did not resolve the issue. Remove previously registered data store Open "Share as Web Layer" tool Run "Analyze" and right click error 00231 > Register Data Source with Server I observed something interesting at this point; the connection string automatically generated in the dialog box truncates the "@hostname" part of the username, and the validation will fail:   I am able to click "Import" in this dialog box and manually specify the .sde connection file, the generated connection string does not malform the username, and the data store can be registered. However, I am right back to the same issue and receive error 00231 once again when attempting to run "Share as Web Layer." I'm hoping someone out there has observed this and found a workaround! 🤞 ...
