Field Selection

Most tools require a desired_output_fields parameter to specify which fields to return. This reduces payload size and improves response efficiency.

Syntax

Pattern	Description	Example
`field`	Single field	`name`
`parent.child`	Nested field	`data.summoner.level`
`array[]`	Array field	`champions[]`
`array[].field`	Field in array items	`data.champions[].name`
`{a,b,c}`	Multiple fields at same level	`{name,title,lore}`
`parent.{a,b}`	Multiple nested fields	`data.summoner.{level,name}`
`array[].{a,b}`	Multiple fields in array items	`data.champions[].{name,title}`

Example

hljs language-json

{
  "desired_output_fields": [
    "data.summoner.{game_name,tagline,level}",
    "data.summoner.league_stats[].{game_type,win,lose}",
    "data.summoner.league_stats[].tier_info.{tier,division,lp}"
  ]
