Promote deployment

Promote a deployment to become the current deployment for its environment. All sticky domains are reassigned from the current deployment to the promoted one, and the previous deployment is scheduled for standby.

The deployment must be ready, not already shutting down, belong to the production environment, and its app must already have a current deployment. Promoting the deployment that is already current fails, unless the app is in a rolled-back state, in which case promoting the current deployment confirms the rollback and re-enables automatic promotion of future deployments.

Promotion runs as a durable workflow: this endpoint returns once the promotion is accepted. Poll getDeployment or listDeployments to observe the result.

Required Permissions

Your root key must have one of the following permissions:

environment.*.promote_deployment (to promote deployments in any environment)
environment.<environment_id>.promote_deployment (to promote deployments in a specific environment)

POST

deployments.promoteDeployment

Authorizations

Authorization

string

header

required

Unkey uses bearer tokens for authentication. Public integrations use root keys, while the dashboard proxy uses short-lived JWTs. To authenticate, include the token in the Authorization header of each request:

Authorization: Bearer unkey_123

Root keys have specific permissions attached to them, controlling what operations they can perform. Legacy permissions use tuple strings like api.*.create_key; resource permissions use Unkey Resource Names plus actions, like unkey:v1:ws_123:keyspaces/*#create_key. Security best practices:

Keep root keys secure and never expose them in client-side code
Use different root keys for different environments
Rotate keys periodically, especially after team member departures
Create keys with minimal necessary permissions following least privilege principle
Monitor key usage with audit logs.

Body

application/json

Promote a ready deployment to become the current deployment for its environment.

deploymentId

string

required

Identifies a resource by either its unique ID or its slug. Accepts a prefixed ID (such as 'proj_' or 'app_') or a slug.

Required string length: 3 - 255

Pattern: ^[a-zA-Z0-9_-]+$

Example:

"proj_1234abcd"

Response

Promotion accepted. Poll getDeployment to observe the result.

meta

object

required

Metadata object included in every API response. This provides context about the request and is essential for debugging, audit trails, and support inquiries. The requestId is particularly important when troubleshooting issues with the Unkey support team.

Show child attributes

data

object

required

Empty response object by design. A successful response indicates this operation was successfully executed.

Rollback deploymentRoll live traffic back to a previous deployment. `deploymentId` is the deployment to roll back TO; the app's current deployment is used as the rollback source automatically. The target deployment must be ready, not already shutting down, belong to the production environment, and must not itself be the current deployment. After a rollback the app is marked as rolled back, which prevents new deployments from automatically taking over live traffic. Promote the rolled-back deployment (or a newer one) to clear this state. Rollback runs as a durable workflow: this endpoint returns once the rollback is accepted. Poll `getDeployment` or `listDeployments` to observe the result. **Required Permissions** Your root key must have one of the following permissions: - `environment.*.rollback_deployment` (to roll back deployments in any environment) - `environment.<environment_id>.rollback_deployment` (to roll back deployments in a specific environment)
