> ## Agent Instructions
> Unkey is two separate products. Compute builds, deploys, and runs apps behind a gateway. API Management issues API keys, enforces rate limits, manages identities and permissions, and reports usage. Say which product a page belongs to; a reader can use either without the other.
> Every Unkey API endpoint is an HTTP POST to https://api.unkey.com/v2/{service}.{procedure} with a root key in the Authorization: Bearer header. Root keys are workspace scoped.
> Error codes have the form err:{system}:{category}:{specific} and each has a page at /errors/{system}/{category}/{specific}.
> The word environment means production or preview in Compute. Rate limiting has four meanings on this site; the glossary lists them.

# unkey api deployments rollback-deployment

> Send production traffic back to an earlier deployment.

<Note>
  You need a root key with the permissions listed on this page. Create one in the dashboard under **Settings > Root Keys**. See [Permission reference](/docs/platform/root-keys/permissions-legacy) for every permission.
</Note>

Move live traffic back to an earlier deployment of an <Tooltip tip="A Compute app: a deployable service inside a project. Not your application in general.">app</Tooltip>. `--deployment-id` is the deployment you want to go back to.

The target must be `ready`, in the production <Tooltip tip="A production or preview environment of a Compute app, not the dashboard label on a key.">environment</Tooltip>, not shutting down, and not already current. After a rollback, new deployments stop taking over live traffic automatically until you promote the rolled-back deployment or a newer one. The command returns right away. Poll `get-deployment` or `list-deployments` for the result.

Rolling back needs an active Compute plan. Without one the API answers 412 with `The workspace has no active Compute plan.` A workspace over its Compute spend cap gets `The workspace is suspended by its Compute spend cap. Raise the spend limit to resume.` See [Compute plans](/docs/compute/get-started/plans).

## Usage

```bash theme={"system"}
unkey api deployments rollback-deployment --deployment-id=<deployment id>
```

## Flags

<ParamField body="--deployment-id" type="string" required>
  ID of the deployment to roll back to.
</ParamField>

### Shared flags

Every `unkey api` command accepts these; [CLI output and shared flags](/docs/platform/cli/output-and-flags) describes them in full.

<ParamField body="--body" type="string">
  A JSON document sent as the request body instead of building it from the flags above. It is mutually exclusive with the request-building flags, and unknown fields are rejected locally. See [Send a raw body](/docs/platform/cli/output-and-flags#send-a-raw-body).
</ParamField>

<ParamField body="--root-key" type="string">
  Root key for the request. Falls back to `UNKEY_ROOT_KEY`, then to the config file written by `unkey auth login`. See [CLI authentication](/docs/platform/cli/authentication).
</ParamField>

<ParamField body="--api-url" type="string" default="https://api.unkey.com">
  Base URL of the API. Falls back to `UNKEY_API_BASE_URL`. You don't normally need to set it.
</ParamField>

<ParamField body="--config" type="string" default="~/.unkey/config.toml">
  Path of the TOML file that `unkey auth login` writes. Falls back to `UNKEY_CONFIG`.
</ParamField>

<ParamField body="--output" type="string">
  Output format. Falls back to `UNKEY_OUTPUT`. Set `json` to print the full response envelope (`meta` and `data`) for piping; any other value prints the request ID followed by `data`.
</ParamField>

## Required permissions

Your root key needs one of:

* `environment.*.rollback_deployment` (any environment)
* `environment.<environment_id>.rollback_deployment` (a specific environment)

If the deployment doesn't exist or your key doesn't have the permission, you get the same 404: `The requested deployment does not exist.` See [Root key permissions](/docs/platform/root-keys/permissions) for the full catalog.

## Examples

Roll back to a known good deployment:

```bash theme={"system"}
unkey api deployments rollback-deployment --deployment-id=d_1234abcd
```

Send the request body as JSON:

```bash theme={"system"}
unkey api deployments rollback-deployment --body='{"deploymentId":"d_1234abcd"}'
```

## API endpoint

The command calls [`POST /v2/deployments.rollbackDeployment`](/docs/compute/api-reference/deployments/rollback-deployment) and prints its response. The request fields carry the same names as the flags in camelCase, which is the shape `--body` expects.
