I am currently having trouble parsing a deeply nested JSON response from a HTTP API call.
My JSON Response is like
{'took': 476,
'_revision': 'r08badf3',
'response': {'accounts': {'hits': [{'name': '4002238760',
'display_name': 'Googleglass-4002238760',
'selected_fields': ['Googleglass',
'DDMonkey',
'Papu New Guinea',
'Jonathan Vardharajan',
'4002238760',
'DDMadarchod-INSTE',
None,
'Googleglass',
'0001012556',
'CC',
'Setu Non Standard',
'40022387',
320142,
4651321321333,
1324650651651]},
{'name': '4003893720',
'display_name': 'Swift-4003893720',
'selected_fields': ['Swift',
'DDMonkey',
'Papu New Guinea',
'Jonathan Vardharajan',
'4003893720',
'DDMadarchod-UPTM-RemotexNBD',
None,
'S.W.I.F.T. SCRL',
'0001000110',
'SE',
'Setu Non Standard',
'40038937',
189508,
1464739200000,
1559260800000]},
After I receive the response I am storing it in data object using json normalize
data = response.json()
data = data['response']['accounts']['hits']
data = json_normalize(data)
However after I normalize my dataframe looks like this
My Curl Statement looks like this
curl --data 'query= {"terms":[{"type":"string_attribute","attribute":"Account Type","query_term_id":"account_type","in_list":["Contract"]},{"type":"string","term":"status_group","in_list":["paying"]},{"type":"string_attribute","attribute":"Region","in_list":["DDEU"]},{"type":"string_attribute","attribute":"Country","in_list":["Belgium"]},{"type":"string_attribute","attribute":"CSM Tag","in_list":["EU CSM"]},{"type":"date_attribute","attribute":"Contract Renewal Date","gte":1554057000000,"lte":1561833000000}],"count":1000,"offset":0,"fields":[{"type":"string_attribute","attribute":"DomainName","field_display_name":"Client Name"},{"type":"string_attribute","attribute":"Region","field_display_name":"Region"},{"type":"string_attribute","attribute":"Country","field_display_name":"Country"},{"type":"string_attribute","attribute":"Success Manager","field_display_name":"Client Success Manager"},{"type":"string","term":"identifier","field_display_name":"Account id"},{"type":"string_attribute","attribute":"DeviceSLA","field_display_name":"[FIN] Material Part Number"},{"type":"string_attribute","attribute":"SFDCAccountId","field_display_name":"SFDCAccountId"},{"type":"string_attribute","attribute":"Client","field_display_name":"[FIN] Client Sold-To Name"},{"type":"string_attribute","attribute":"Sold To Code","field_display_name":"[FIN] Client Sold To Code"},{"type":"string_attribute","attribute":"BU","field_display_name":"[FIN] Active BUs"},{"type":"string_attribute","attribute":"Service Type","field_display_name":"[FIN] Service Type"},{"type":"string_attribute","attribute":"Contract Header ID","field_display_name":"[FIN] SAP Contract Header ID"},{"type":"number_attribute","attribute":"Contract Value","field_display_name":"[FIN] ACV - Annual Contract Value","desc":true},{"type":"date_attribute","attribute":"Contract Start Date","field_display_name":"[FIN] Contract Start Date"},{"type":"date_attribute","attribute":"Contract Renewal Date","field_display_name":"[FIN] Contract Renewal Date"}],"scope":"all"}' --header 'app-token:YOUR-TOKEN-HERE' 'https://app.totango.com/api/v1/search/accounts'
So ultimately I want to store the Response in a dataframe along with the field names.
I've had to do this sort of thing a few times in the past (flatten out a nested json) I'll explain my process, and you can see if it works, or at least can then work the code a bit to fit your needs.
1) Took the data
response, and completely flattened it out using a function. This blog was very helpful when I first had to do this.
2) Then it iterates through the flat dictionary created to find where each rows and columns are needed to be created by the numbering of the new key names within the nested parts. There are also keys that are unique/distinct, so they don't have a number to identify as a "new" row, so I account for those in what I called special_cols
.
3) As it iterates through those, pulls the specified row number (embedded in those flat keys), and then constructs the dataframe in that way.
It sounds complicated, but if you debug and run line by line, you could see how it works. None-the-less, I believe it should get you what you need.
