# Preview what a delete would destroy

GET https://api.finput.com.au/api/v1/deletions/preview

For a client's own delete confirmation screen: the rows that would go, the links that would be broken, and the sentences to show. When `plan.blocked` is true the delete will be refused and the sentences are the refusal — render them and disable the button rather than letting the user find out on the `DELETE`.

Gated on the same permission the delete itself requires, so a caller cannot use the preview to learn about rows they could not delete. A row belonging to another organisation answers `404`, the same as one that does not exist. Works with an API token.

Reference: https://docs.finput.com.au/api/endpoints/deletions/preview-deletion

## Authentication

- `Authorization` header (bearer token, required) — JWT access token obtained from `POST /api/v1/auth/login`, or a `finput_sk_...` API token

## Request

### Query parameters

- `target` (enum, required) — What kind of row is being deleted.
  - Allowed values: `product`, `rate_bracket`, `uplift`, `approval`
- `id` (integer, required) — The row's id.

## Response

### 200

The plan and its sentences.

- `plan` (DeletePreviewPlan, optional)
- `summary_lines` (list of string, optional) — The sentences the delete modal renders — the refusal when blocked, the consequences when not.

## Errors

### 400 Bad Request Error

Unknown `target`, or `id` is not a row id.

- `error` (string, optional)
- `errors` (map from string to list of string, optional)

### 403 Forbidden Error

The caller lacks the delete permission for this target.

- `error` (string, optional)
- `errors` (map from string to list of string, optional)

### 404 Not Found Error

No such row for this caller.

- `error` (string, optional)
- `errors` (map from string to list of string, optional)

## Types

### DeletePreviewPlan

- `target` (enum, optional)
  - Allowed values: `product`, `rate_bracket`, `uplift`, `approval`
- `id` (integer, optional)
- `name` (string, optional, nullable)
- `organisation_id` (integer, optional, nullable)
- `blocked` (boolean, optional)
- `blockers` (list of DeletePreviewPlanBlockersItems, optional) — Present only when `blocked` is true.
- `removes` (map from string to integer, optional) — Row counts by kind, zero counts omitted. Present only when `blocked` is false.
- `unlinks` (map from string to any, optional)

### DeletePreviewPlanBlockersItems
