NiFi Variables
Hello community,
I'm looking for a way to edit or add to the new "variables" feature
programmatically, such as through the API or other. For instance, I'd
like to use a variable to configure the remote host for my SFTP
collection, and then be able to change the value through an automated
job when the remote host changes. This would be especially useful for
processors that don't allow an input relationship.
Any suggestions or comments would be welcome.
Thanks,
Scott

Thank you Daniel and Charlie. Excellent tips. That's what I needed to
get started.

Hi Scott,
NiPyApi provides a python client for this purpose. There are calls to
get/set variables in the canvas module.
https://github.com/Chaffelson/nipyapi
Let me know if you have any troubles with it.

Take a look at your browsers developer tools when you set variables and
mimic the calls in code. We do this using a swagger generated client and it
works well.
