Update policy

Update a single policy in place without resending the environment's full
policy list. The policy keeps its id and its position in the evaluation
order, and all other policies are untouched.

Omitted fields keep their stored values; at least one updatable field
must be provided. Setting match to null removes all match expressions
so the policy applies to every request. Providing one of keyauth,
ratelimit, firewall or openapi replaces the policy's rule
entirely, including switching its type; at most one may be set.

Policy ids are regenerated whenever gateway.setPolicies replaces the
list, so fetch current ids via gateway.listPolicies first.

Required Permissions

Your root key must have one of the following permissions:

environment.*.update_policy (for any environment)
environment.<environment_id>.update_policy (for a specific environment)

Authorization

Authorizationstringheaderrequired#

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.

actionenum<string>required#

What to do with matching requests.

Options:ACTION_DENY

openapiobject#

Validates matching requests against the app's uploaded OpenAPI spec. Has no
configuration of its own. If no spec has been uploaded for the deployment,
the policy is a no-op and requests pass through unvalidated.

loggingobject#

Adds request data to the log entries of matching requests. The gateway
always records a basic log entry for every request: method, host, path,
status, and latency. Each capture setting is a separate opt-in: request
headers, response headers, request body, response body, and query data.
The policy's match expressions select the requests. A policy without
match expressions matches every request. If more than one enabled
logging policy matches a request, the gateway combines their settings.
The gateway always redacts the Authorization header and configured key
locations before it stores headers or query data.

Show child attributes

requestHeadersboolean#

Capture request headers, the user agent, and the client IP. The user
agent and client IP are included because they identify the client.

Default: false

responseHeadersboolean#

Capture response headers.

Default: false

requestBodyboolean#

Capture the request body, up to the capture limit.

Default: false

responseBodyboolean#

Capture the response body, up to the capture limit.

Default: false

queryboolean#

Capture the query string and query parameters. Query data is a
separate opt-in because URLs can contain secrets, for example
?api_key=....

Default: false

Responses

application/json

Successfully updated the policy.

metaobjectrequired#

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

requestIdstringrequired#

A unique id for this request. Always include this ID when contacting support about a specific API request. This identifier allows Unkey's support team to trace the exact request through logs and diagnostic systems to provide faster assistance.

dataobjectrequired#

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

metaobjectrequired#

Show child attributes

requestIdstringrequired#

errorobjectrequired#

Base error structure following Problem Details for HTTP APIs (RFC 7807). This provides a standardized way to carry machine-readable details of errors in HTTP response content.

Show child attributes

detailstringrequired#

A human-readable explanation specific to this occurrence of the problem. This provides detailed information about what went wrong and potential remediation steps. The message is intended to be helpful for developers troubleshooting the issue.

statusintegerrequired#

HTTP status code that corresponds to this error. This will match the status code in the HTTP response. Common codes include 400 (Bad Request), 401 (Unauthorized), 403 (Forbidden), 404 (Not Found), 409 (Conflict), and 500 (Internal Server Error).

titlestringrequired#

A short, human-readable summary of the problem type. This remains constant from occurrence to occurrence of the same problem and should be used for programmatic handling.

typestringrequired#

A URI reference that identifies the problem type. This provides a stable identifier for the error that can be used for documentation lookups and programmatic error handling. When followed, this URI should provide human-readable documentation for the problem type.

errorsobject[]required#

List of individual validation errors that occurred in the request. Each error provides specific details about what failed validation, where the error occurred in the request, and suggestions for fixing it. This granular information helps developers quickly identify and resolve multiple issues in a single request without having to make repeated API calls.

Show child attributes

locationstringrequired#

JSON path indicating exactly where in the request the error occurred. This helps pinpoint the problematic field or parameter. Examples include:

'body.name' (field in request body)
'body.items[3].tags' (nested array element)
'path.apiId' (path parameter)
'query.limit' (query parameter)
Use this location to identify exactly which part of your request needs correction.

messagestringrequired#

Detailed error message explaining what validation rule was violated. This provides specific information about why the field or parameter was rejected, such as format errors, invalid values, or constraint violations.

fixstring#

A human-readable suggestion describing how to fix the error. This provides practical guidance on what changes would satisfy the validation requirements. Not all validation errors include fix suggestions, but when present, they offer specific remediation advice.
