Developer Documentation Korean: API, SDK, 매개변수, 반환값

Core examples: API, SDK, 매개변수, 반환값, 엔드포인트, 인증키, 요청, 응답, 오류코드.

Developer Korean keeps English acronyms but Korean controls the requirement

A documentation page says:

요청 시 인증키를 헤더에 포함해야 하며, 필수 매개변수가 누락된 경우 오류코드 400을 반환합니다.

The acronyms may be familiar, but the Korean sentence defines what the developer must send, what is required, and what error returns.

The key principle is:

Developer-documentation Korean must be read by input, output, requirement, and failure mode.

API

API

Application Programming Interface.

Korean docs use:

API 호출 API call

API 문서 API documentation

API 키 API key

API 응답 API response

Learner action: API stays in English letters, but Korean verbs around it matter.

SDK

SDK

Software Development Kit.

Related:

SDK 설치 install SDK

SDK 초기화 initialize SDK

SDK 버전 SDK version

SDK 연동 SDK integration

Learner action: SDK text is usually implementation/setup procedure.

매개변수

매개변수

parameter.

Related:

필수 매개변수 required parameter

선택 매개변수 optional parameter

쿼리 매개변수 query parameter

요청 매개변수 request parameter

Korean docs may also use:

파라미터 parameter, loanword

Learner action: identify name, type, required status, description, example.

반환값

반환값

return value.

Related:

반환하다 return

응답값 response value

결과값 result value

반환 형식 return format

Learner action: return values define what the API or function gives back.

엔드포인트

엔드포인트

endpoint.

Related:

요청 URL request URL

기본 URL base URL

경로 path

메서드 method

Learner action: endpoint plus method defines where request goes.

인증키

인증키

authentication key/API key.

Related:

API 키 API key

액세스 토큰 access token

비밀키 secret key

토큰 발급 token issuance

Learner action: authentication key is sensitive. Do not expose it.

요청 and 응답

요청

request.

응답

response.

Related:

요청 본문 request body

요청 헤더 request header

응답 코드 response code

응답 데이터 response data

Learner action: docs are often request/response architecture.

오류코드

오류코드

error code.

Related:

상태코드 status code

에러코드 error code, loanword

오류 메시지 error message

잘못된 요청 bad request

Learner action: error code tells failure type and debugging path.

Developer documentation table

Request sentence walkthrough

page 매개변수는 선택값이며, 지정하지 않을 경우 기본값 1이 적용됩니다.

Breakdown:

page 매개변수 page parameter

선택값 optional value

지정하지 않을 경우 if not specified

기본값 1 default value 1

적용됩니다 is applied

Plain reading:

The page parameter is optional, and if it is not specified, the default value 1 is applied.

Learner action: parameter, requirement status, default.

Error sentence walkthrough

인증키가 유효하지 않은 경우 401 오류코드를 반환합니다.

Breakdown:

인증키 authentication key

유효하지 않은 경우 if invalid

401 오류코드 401 error code

반환합니다 returns

Plain reading:

If the authentication key is invalid, the API returns error code 401.

Learner action: failure condition and response.

Common learner traps

요청

Can be HTTP request, user request, or support request depending context.

반환값

Function/API return value, not refund.

필수/선택

Required/optional in docs, not general life advice.

인증키

Sensitive credential.

오류코드

Not explanation by itself; must read message and condition.

Example bank walkthrough

API

Application interface.

Learner action: call/interface context.

SDK

Development kit.

Learner action: install/integrate.

매개변수

Parameter.

Learner action: input field.

반환값

Return value.

Learner action: output.

엔드포인트

Endpoint.

Learner action: URL/path target.

인증키

Authentication key.

Learner action: credential.

요청

Request.

Learner action: input/action to server.

응답

Response.

Learner action: output from server.

오류코드

Error code.

Learner action: failure classification.

Developer-doc reading workflow

When reading Korean developer docs:

1. Identify API or SDK context.
2. Find endpoint and method.
3. Check authentication requirement.
4. List required parameters.
5. List optional parameters and defaults.
6. Read request body/header format.
7. Read return values and data types.
8. Read error codes and conditions.
9. Check version/deprecation notes.
10. Run sample mentally before implementing.

Developer-doc section table

Developer documentation Korean should be read by documentation section.

The English acronyms stay visible, but Korean grammar describes the requirements.

Parameter requirement table

Technical translation should preserve type, requirement, and behavior.

Docs caution

매개변수, 요청, 응답, 반환값, 인증키, and 오류코드 are implementation terms. Do not paraphrase so loosely that required/optional status, data type, endpoint, or error behavior is lost.

A strong tool for this article would turn docs into implementation fields.

Suggested functions:

1. Endpoint/method extractor.
2. Required/optional parameter table.
3. Authentication warning.
4. Request/response divider.
5. Return-value field map.
6. Error-code condition table.
7. Plain-language implementation checklist.

Final rule

Developer-documentation Korean is precise because code is unforgiving.

API and SDK name the interface/tool. 매개변수 defines input. 반환값 defines output. 엔드포인트 and 인증키 define access. 요청 and 응답 define flow. 오류코드 defines failure.

Read the requirement before copying the example.
