FAQ: I want to get the display name via API
## Answer
Specify the ApiDataType property of "[View](/ja/manual/table-management-view)" as "KeyValues".
---
## Overview
When retrieving information about a child table using the API, the value of the linked item in the response is usually the record ID (the target record in the parent table), but by specifying the ApiDataType property of "[View](/ja/manual/table-management-view)" as "KeyValues", the response will be returned with the display name (the title of the target record in the parent table).
## Sample Data
This FAQ is written based on the parent-child table and record information below.

## ②When The Response Format Is Changed to The Display Name
You can change the response format to return the display name by specifying the ApiDataType property in the view of the data to be sent. For details on the ApiDataType property, please refer to the following manual.
[Developer Features: JSON Data Layout: View](https://pleasanter.org/manual/api-view)
<details>
<summary>Sample code (Python)</summary>
<br>
Added the ApiDataType property and the related ApiColumnKeyDisplayType and ApiColumnValueDisplayType properties to the View, so that the Key of each response item is returned as the column name (ColumnName) and the Value is returned as the display name (DisplayValue).
<br>
```
import requests
import json
# Specify site ID
site_id = 620
# Specify API key
api_key = "xxxxx..."
# Specify API URL
url = f"http://localhost/api/items/{site_id}/get"
# Specify data to send
data = {
"ApiVersion": 1.1,
"ApiKey": api_key,
"View": {
"ApiDataType": "KeyValues",
"ColumnFilterHash": {
"ClassB": "[\"System Development\"]"
},
"ApiColumnKeyDisplayType": "ColumnName",
"ApiColumnValueDisplayType": "DisplayValue"
}
}
# Send POST request
response = requests.post(url, json=data)
# Process response
if response.status_code == 200:
response_data = json.loads(response.content)
print(json.dumps(response_data, indent=4, ensure_ascii=False))
else:
print(f"ErrorCode: {response.status_code}")
print(response.text)
```
