# Create Produce Policy for Virtual Cluster

`POST /v1/event-gateways/{gatewayId}/virtual-clusters/{virtualClusterId}/produce-policies#EncryptFields`

Creates a new produce policy associated with the specified Event Gateway virtual cluster.

## Query parameters

- `before` string, uuid
- `after` string, uuid

## Request body

- EventGatewayParsedRecordEncryptFieldsPolicyCreate — Encrypts fields of parsed Kafka records using AES_256_GCM. Keys are therefore 256 bits long. Note this policy can only be used as a child of a `EventGatewayProduceSchemaValidationPolicy` policy. **Requires a minimum runtime version of `1.2`**.
  - `type` 'encrypt_fields', required — The type name of the policy.
  - `name` string — A unique user-defined name of the policy.
  - `description` string — A human-readable description of the policy.
  - `enabled` boolean — Whether the policy is enabled.
  - `labels` Labels — Labels store metadata of an entity that can be used for filtering an entity list or for searching across entity types. Keys must be of length 1-63 characters, and cannot start with "kong", "konnect", "mesh", "kic", or "_".
  - `config` EventGatewayParsedRecordEncryptFieldsConfig, required — The configuration of the encrypt parsed record policy.
    - `failure_mode` 'reject' | 'passthrough' | 'mark', required — Describes how to handle a failure in a policy applied to produced records. * `reject` - rejects the record batch. * `passthrough` - passes the record silently to the backend cluster even though policy execution failed. * `mark` - passes the record to the backend cluster but marks it with a `kong/policy-failure-<id>` header whose value is the reason for the policy failure (truncated to 512 characters). **Requires a minimum runtime version of `1.2`**.
    - `encrypt_fields` EventGatewayParsedRecordEncryptionSelector[], required — Selects which fields to encrypt and with what keys.
      - `encryption_key` union, required — The key to use for encryption.
        - EncryptionKeyAWS — The AWS KMS key to use for encryption.
          - `type` 'aws', required
          - `arn` string, required — The AWS KMS key ARN.
        - EncryptionKeyStatic — A static encryption key.
          - `type` 'static', required
          - `key` EncryptionKeyStaticReference, required — A static encryption key reference by ID.
            - `id` string, uuid, required — The ID of the static key defined in the key source.
      - `paths` object[], required
        - `match` string, required — A field selector. It can select nested fields and array entries. Currently supported are exact matches.
  - `condition` string — A string containing the boolean expression that determines whether the policy is applied. When the policy is applied as a child policy of schema_validation, the expression can also reference `record.value` fields.
  - `parent_policy_id` string, uuid, required — The unique identifier of the parent schema validation policy.
