description: >-
  Versioning, deprecation, SLA, and status posture for the Amazon AppSync
  management API. AWS uses a dated service API version rather than URI-path
  major versions and does not publish RFC 8594 Sunset/Deprecation headers.
versioning:
  scheme: dated-api-version
  current: '2017-07-25'
  docs: https://docs.aws.amazon.com/appsync/latest/APIReference/Welcome.html
  notes: >-
    The AWS AppSync service API version is 2017-07-25 (sent as X-Amz-Target /
    signed request metadata). SDKs pin this version. The REST control-plane
    resource paths in the captured OpenAPI use a /v1 prefix.
deprecation:
  policy_url: https://docs.aws.amazon.com/general/latest/gr/aws-sdk-deprecation.html
  sunset_header: false
  deprecation_header: false
  notes: >-
    AWS announces deprecations via documentation, the AWS Health Dashboard, and
    account notifications rather than HTTP Sunset/Deprecation headers. AppSync
    has deprecated Elasticsearch data sources in favor of OpenSearch (the spec
    retains ElasticsearchDataSourceConfig for backward compatibility).
