To update a field-level encryption configuration, you must have the configuration's ID and ``ETag``. The ID is returned in the output of the `create-field-level-encryption-config <create-field-level-encryption-config.html>`_ and `list-field-level-encryption-configs <list-field-level-encryption-configs.html>`_ commands. To get the ``ETag``, use the `get-field-level-encryption <get-field-level-encryption.html>`_ or `get-field-level-encryption-config <get-field-level-encryption-config.html>`_ command. Use the ``--if-match`` option to provide the configuration's ``ETag``. :: aws cloudfront update-field-level-encryption-config \ --id C3KM2WVD605UAY \ --if-match E2P4Z4VU7TY5SG \ --field-level-encryption-config file://fle-config.json The file ``fle-config.json`` is a JSON document in the current directory that contains the following:: { "CallerReference": "cli-example", "Comment": "Updated example FLE configuration", "QueryArgProfileConfig": { "ForwardWhenQueryArgProfileIsUnknown": true, "QueryArgProfiles": { "Quantity": 0 } }, "ContentTypeProfileConfig": { "ForwardWhenContentTypeIsUnknown": true, "ContentTypeProfiles": { "Quantity": 1, "Items": [ { "Format": "URLEncoded", "ProfileId": "P280MFCLSYOCVU", "ContentType": "application/x-www-form-urlencoded" } ] } } } Output:: { "ETag": "E26M4BIAV81ZF6", "FieldLevelEncryption": { "Id": "C3KM2WVD605UAY", "LastModifiedTime": "2019-12-10T22:26:26.170Z", "FieldLevelEncryptionConfig": { "CallerReference": "cli-example", "Comment": "Updated example FLE configuration", "QueryArgProfileConfig": { "ForwardWhenQueryArgProfileIsUnknown": true, "QueryArgProfiles": { "Quantity": 0, "Items": [] } }, "ContentTypeProfileConfig": { "ForwardWhenContentTypeIsUnknown": true, "ContentTypeProfiles": { "Quantity": 1, "Items": [ { "Format": "URLEncoded", "ProfileId": "P280MFCLSYOCVU", "ContentType": "application/x-www-form-urlencoded" } ] } } } } }
