# Promote Agent to Production

> Pin production to the version currently in staging.

### Overview

Moves the agent's `production` pointer to whatever `staging` is pinned to and records a deployment carrying that version's original semver; promoting never mints a new number. Phone numbers attached to the agent begin answering with the promoted version. No request body. The server does not run checks here: start one with [Start Check Run](/api-v2/post/agents-id-environments-env-check-runs) beforehand and gate on its result yourself.

Requires an admin, owner, operator, or prompter role.

### Headers

<ParamField header="authorization" type="string" required>
  Your API key for authentication.
</ParamField>

### Path Parameters

<ParamField path="agent_id" type="string" required>
  The agent's unique identifier.
</ParamField>

### Response

<ResponseField name="data.semver" type="string">
  The promoted version's number, for example `1.4.0`.
</ResponseField>

<ResponseField name="data.environments" type="array">
  The agent's three environments after the promote. Each has `id`, `env_type` (`dev`, `staging`, or `production`), and `current_version_id` (the pinned version, or `null` if unpinned). `staging` and `production` now point at the same version.
</ResponseField>

<ResponseField name="errors" type="null | array">
  `null` on success, or a list of error objects if the request failed. Returns `400 STAGING_UNPINNED` when nothing has been published to staging yet.
</ResponseField>
