# check\_manifest

Generated automatically from the [published contract sources](/cloud/reference/about/#contract-sources).

A script calls this action over HTTPS at `POST https://turnzero.ai/api/v1/actions/check_manifest`, with a bearer credential and the action's payload as the JSON body. It also accepts `GET`.

**Build metadata:** Registered in this build. Registration describes the default dispatcher in this build. It does not guarantee that a caller has the required credential or grant, that a tool is listed for that connection, or that the required service is configured.

## Contract description

Check a whole manifest for your application without recording it or setting anything up\. Runs `submit_manifest`'s checks before any change and returns `checked`, `changed`, and `difference`, listing paths added, removed or changed\. A refusal gives the same failing path, status and error as submission\. This does not predict sign\-outs, or refusals from setup steps or custom\-domain writes\. Call `submit_manifest` with the manifest to apply it\.
