When ArcGIS Field maps is opened by a third party application using its URL schema, it would be great if the parameters could be stored in session variables that could then be used by other parts of the data collection process.
For example, a third party app might pass in a work order ID. Then For every asset that is digitised, arcade could be run that inserts the ID into a field. Every asset will have a common work order ID that can be used by back-office systems to view all assets for that job.
