Parsing Meraki CMX API data on props.conf

I'm trying to parse data coming from Cisco Meraki CMX using HTTP Event Collector. The raw data was JSON API.
I'm using props.conf

[http_json]
INDEXED_EXTRACTIONS = json
SHOULD_LINEMERGE = false
KV_MODE = json
NO_BINARY_CHECK = 1
TIME_PREFIX = "seenTime": "
TIME_FORMAT = %Y-%m-%d
MAX_DAYS_AGO = 5000

but the event in the Splunk is only parsed to only one event. Do I need to edit transforms.conf for this kind of data or is there any mistake on my props.conf? Thank you.

This is the sample JSON raw data that I'm trying to parse.

Apparently the fields are extracted, and this query can be used for expansion. I think there is no problem.

Hi @kamlesh_vaghela , I'm just trying to simulate the Meraki CMX API process using Postman and the sample events I gathered was from this site https://documenter.getpostman.com/view/897512/71FUpux?version=latest#7f7ed3e0-0ed4-8d55-c39d-b802dad....

Here is the whole event from this site,
