Can we fire a NIFI rest-api query to get the process-group or any other element ID by entering the name of the element ?

[#1]

For example I want to get the ID of the process-gorup which is at root level by asking the following query http://localhost:9090/nifi-api/process-groups/root/process-groups?name=Process-group1

The problem I am facing here is this results as all the processor group that are available at root level.But I'm only interested in the particular process-group.How can I get that information only not about all processor group?

@Daminee Sao,

By using restApi search url you can get the id of the process group

RestApi URL:-

curl -i -X GET http://localhost:9090/nifi-api/flow/search-results?q=<name(or)id>;

Example:-

I'm having flowfiledrop as the name of process group in my NiFi and to get the id of the flowfiledrop process group ,

RestApi url would be

curl -i -X GET http://localhost:9090/nifi-api/flow/search-results?q=flowfiledrop

As you can see in i've mentioned flowfiledrop process group name in q parameter

$ curl -i -X GET http://localhost:9090/nifi-api/flow/search-results?q=flowfiledrop

the id of the flowfile drop process group is 619a2801-0161-1000-a4c2-95e4430e977f.

Very helpful! Thanks @Shu.

Also, be sure to put %20 in place of spaces in the search query.

Is there a way to do wildcard search using this?
