AppConfig — AWS AppConfig

AWS docs: https://docs.aws.amazon.com/appconfig/2019-10-09/APIReference/

AWS AppConfig uses the REST JSON protocol, served at the paths AWS models: /applications and /tags/{ResourceArn}. There is no X-Amz-Target namespace — the AWS models give AppConfig none.

---

Notes

• Routes are the modeled ones, e.g. POST /applications, POST /applications/{ApplicationId}/environments.
• /applications is shared with Service Catalog AppRegistry, which models the same tree. Overcast picks the service from the SigV4 credential scope, so an AppConfig SDK call must be signed as appconfig; unsigned callers reach AppRegistry, as they always have.
• /tags/{ResourceArn} is dispatched on the ARN, so an arn:aws:appconfig:… ARN reaches AppConfig’s own tag store.
• CreateHostedConfigurationVersion and GetHostedConfigurationVersion carry the configuration as the HTTP payload and the metadata in Application-Id, Configuration-Profile-Id, Version-Number, Description, Content-Type and VersionLabel headers, as AWS binds them.
• List operations page with the max_results and next_token query parameters and answer { "Items": [...], "NextToken": "..." }.
• Unrecognized operations return a JSON 501 Not Implemented error response.
• Resources are stored in-memory with hierarchical relationships (Application → Environment, Application → ConfigurationProfile).
• Resources are not region-scoped: an application created in one region is visible in another.
• The data plane (StartConfigurationSession, GetLatestConfiguration) is a separate AWS service — see appconfigdata.md.

Endpoints

Applications

Operation	Status	Notes	AWS Docs
CreateApplication	✅ Supported	Creates an application; an inline Tags map is applied	docs
GetApplication	✅ Supported	Returns application details	docs
ListApplications	✅ Supported	Lists all applications, paginated by max_results/next_token	docs
UpdateApplication	✅ Supported	Updates Name and Description; an omitted member leaves the stored value alone	docs
DeleteApplication	✅ Supported	Deletes an application and its tags; environments and profiles beneath it are left in place	docs

Environments

Operation	Status	Notes	AWS Docs
CreateEnvironment	✅ Supported	Creates an environment for an application; State is always READY_FOR_DEPLOYMENT because deployments are not emulated	docs
GetEnvironment	✅ Supported	Returns environment details	docs
ListEnvironments	✅ Supported	Lists environments for an application, paginated by max_results/next_token	docs
DeleteEnvironment	✅ Supported	Deletes an environment and its tags; x-amzn-deletion-protection-check is ignored	docs

Configuration Profiles

Operation	Status	Notes	AWS Docs
CreateConfigurationProfile	✅ Supported	Creates a configuration profile; Name and LocationUri are required and Validators are stored but never run	docs
GetConfigurationProfile	✅ Supported	Returns configuration profile details	docs
ListConfigurationProfiles	✅ Supported	Lists profile summaries, filtered by the type query parameter and paginated by max_results/next_token	docs
DeleteConfigurationProfile	✅ Supported	Deletes a configuration profile and its tags; hosted versions beneath it are left in place	docs

Hosted Configuration Versions

Operation	Status	Notes	AWS Docs
CreateHostedConfigurationVersion	✅ Supported	Stores the request payload against a profile; VersionNumber auto-increments, a stale Latest-Version-Number header is a ConflictException, and content over 1 MB is rejected with PayloadTooLargeException	docs
GetHostedConfigurationVersion	✅ Supported	Returns the raw content as the response payload with the metadata in headers	docs
ListHostedConfigurationVersions	✅ Supported	Returns version summaries newest first, filtered by the version_label query parameter and paginated by max_results/next_token	docs
DeleteHostedConfigurationVersion	✅ Supported	Deletes a single version; other versions of the profile are untouched and version numbers are not reused	docs

Tags

Operation	Status	Notes	AWS Docs
TagResource	✅ Supported	Adds or overwrites tags on applications, environments, and configuration profiles	docs
UntagResource	✅ Supported	Removes tags by the tagKeys query parameter	docs
ListTagsForResource	✅ Supported	Returns tags for applications, environments, and configuration profiles	docs
