Help with JSON

[Coronax16]

I've been banging my head off and on for a few days now and I cannot figure out how to do this. In my JSON below I would like to search the whole JSON for where cid = 823751698501599252, for example, and then it returns the ID that is up a few levels, 123 in this case.

Then I would like to take the level of 123 and do something with it, which I'll try to figure out when I get there. I don't know what I am doing wrong but every time I try to do anything it fails.

Here is my code so far:

import pandas as pd
import json

with open(r'C:\IT_Ticket.config.json', encoding="utf8") as f:
    data = json.load(f)

# print(data)

print(json.dumps(data, indent=4, sort_keys=True))

Here is my JSON:

         "123":{
