# Retrieve Application Revision

`POST /applications/revisions/retrieve`

Retrieve one application revision by reference.

Accepts application / variant / revision references for direct lookup,
or an environment reference (with optional `key`) to resolve the
currently-deployed revision in that environment. Returns the revision
including its `data` payload (URL, parameters, schemas), which clients
use to invoke the application.
Set `resolve: true` to inline embedded references inside `data`.

## Request body

- ApplicationRevisionRetrieveRequest — Request body for `POST /applications/revisions/retrieve`. Resolves to a single revision by one or more reference types. Every reference supplied must agree with the resolved revision; contradictions return HTTP 400. See the [Applications guide](/reference/api-guide/applications#invocation).
