How to delete a variable from nifi variable registry through nifi rest api ?

Hello experts,

 

I am using below api to create and update variable registry variables..

/nifi-api/process-groups/" + processGroupId + "/variable-registry/update-requests

 But I am unable to delete any already created variable from specific processor group variable registry using nifi api.

Which api I am suppose to use to delete a variable registry variables?

 

Thanks,

Mahendra

After testing, in order to remove a variable you need to send an update request where that variable's value is null.

Hello Mahendra,

 

Have you tried sending an update request that includes all the variables except the one you wish to delete? If that doesn't work I'll run some tests next time I'm at office and post an update.
