# Abort an upload

> Cancel an unfinished upload.

`POST https://api.codebuckets.clatterlabs.xyz/v1/uploads/{upload_id}/abort` (key permission: `buckets:write`)

Cancels an upload that isn't complete and frees the space it reserved.

## Authorizations

- `Authorization` (string, required): Your API key as a bearer token: `Bearer clsk_...`. Create keys in the [Console](https://console.clatterlabs.com/api-keys) with the Code Buckets permissions you need.
- `X-Clatter-Account` (string, required): The Account ID that owns the key, like `CL-7K2M9QXA`. Find it in Console › Settings. A missing value answers `401 missing_account_id`; someone else's answers `401 account_mismatch`.

## Path parameters

- `upload_id` (string, required): The upload id (`cbo_…`) from [Start an upload](/api-reference/code-buckets/uploads/create).

## Response

- `object` (string): `upload`.
- `id` (string): The upload id.
- `status` (string): `aborted`.

## Example request

```bash
curl -X POST "https://api.codebuckets.clatterlabs.xyz/v1/uploads/UPLOAD_ID/abort" \
  -H "Authorization: Bearer $CLATTER_API_KEY" \
  -H "X-Clatter-Account: $CLATTER_ACCOUNT_ID"
```
