jmeter Json filter data based on condition - json

Question

I am working on jmeter and trying to get values from a Json response.
I have below Json:

I just want to get all the courses (learnable_id) which are
State = Created
learnable_type = CourseTemplate
Once I get all the learnable_id which met above condition then I can return random number from that array.
How do I get this?
Thanks in advance.

Answer 1

You can use JSON path to extract json key values by applying required filters
Add a JSON extractor as a child of your request where you are getting above respone.
use the following configuration in JSON extractor
Json path Expression : $..[?(#.learnable_type=='CourseTemplate' && #.state == 'created')].learnable_id
match no : 0 (This will return a random matach from the possible matches in JMeter
as shown below
