Using optionalFields in queries

Overview​

Some endpoints don’t return every field by default when you request a resource.
You can retrieve these additional fields by specifying them in the optionalFields query parameter.

This guide demonstrates how to request optional fields using the Get All Feature Flags endpoint as an example.

Requesting optionalFields​

Example 1: Query without optionalFields​

Request​

curl -L -X GET 'https://api.kameleoon.com/feature-flags' \
  -H 'Content-Type: application/json' \
  -H 'Accept: */*' \
  -H 'Authorization: Bearer <ACCESS_TOKEN>'

Response​

[
  {
    "id": 395,
    "featureKey": "plp___4_products_per_row",
    "name": "PLP : 4 products per row",
    "description": "",
    "tags": [],
    ...
  },
  ...
]

Notice that the tags field is empty. Optional fields return empty values unless they are explicitly requested.

Example 2: Query including the tags field​

Request​

note

You can request multiple optional fields by separating them with commas in the optionalFields parameter. For example: optionalFields=tags,description

curl -L -X GET 'https://api.kameleoon.com/feature-flags?optionalFields=tags' \
  -H 'Content-Type: application/json' \
  -H 'Accept: */*' \
  -H 'Authorization: Bearer <ACCESS_TOKEN>'

Response​

[
  {
    "id": 395,
    "featureKey": "plp___4_products_per_row",
    "name": "PLP : 4 products per row",
    "description": "",
    "tags": [
      "product page"
    ],
    ...
  },
  ...
]
