I would like to make a callout on package uninstall (from a package uninstall script) to notify an external application that the package was uninstalled. The page says it's not possible.
The uninstall script has the following restrictions. You can’t use it to initiate batch, scheduled, and future jobs, to access Session IDs, or to perform callouts.
Is there any alternative way to notify my external application that this package was uninstalled?
