# List Grade Changes

GET https://api.taktoria.com/api/v1/key-results/{keyResultId}/grade-changes

Who changed a key result's scorecard grades, most recent first.

Reference: https://docs.taktoria.com/api-reference/okr/list-grade-changes

## Authentication

- `Authorization` header (bearer token, required) — Bearer authentication of the form `Bearer <token>`, where token is your auth token.

## Servers

- `https://api.taktoria.com/api/v1` (Production, default)
- `http://localhost:3000/api/v1` (Local)

## Request

### Path parameters

- `keyResultId` (string, required)

### Query parameters

- `limit` (integer, optional)
- `cursor` (string, optional)

## Response

### 200

- `data` (list of GradeChange, required)
- `hasMore` (boolean, required)
- `nextCursor` (string, optional)

## Errors

### 404 Not Found Error

- `error` (ErrorDetail, required)

### 429 Too Many Requests Error

Rate limited (`rate_limited`): the key, the signed-in person, the workspace or an expensive endpoint's own budget is used up for now. `Retry-After` says how many seconds to wait, and `details` names the `policy`, its `limit`, `windowSeconds` and `retryAfter`. Every answer to an authenticated request carries the IETF `RateLimit-Policy` and `RateLimit` headers, so a client can slow down before it gets this. Nothing was done; wait and send it again. See "Rate limits".

- `error` (ErrorDetail, required)

## Types

### GradeChange

One change to a scorecard grade. A clear reads as an absent `toScore`; a reset score as an absent `toScore` with `toNoScore`.

- `id` (string, required)
- `keyResultId` (string, required)
- `checkpoint` (enum, required) — Where the scorecard reads a grade. A quarterly objective is read at MID (halfway through its quarter) and FINAL; an annual one at the end of Q1, Q2 and Q3, and FINAL at the end of the year.
  - Allowed values: `MID`, `Q1`, `Q2`, `Q3`, `FINAL`
- `fromNoScore` (boolean, required)
- `toNoScore` (boolean, required)
- `changedAt` (datetime, required)
- `fromScore` (double, optional)
- `toScore` (double, optional)
- `changedById` (string, optional)

### ErrorDetail

- `code` (string, required) — A stable machine-readable code such as `not_found`.
- `message` (string, required)
- `details` (any, optional)
