# Compare revisions

POST https://{hostname}/edgeworkers/v1/ids/{edgeWorkerId}/revisions/{revisionId}/compare
Content-Type: application/json

__Beta__ View dependency differences between two revisions of the same EdgeWorker activation. To learn more about Flexible composition refer to the [EdgeWorkers guide](https://techdocs.akamai.com/edgeworkers/docs/flexible-composition).

Reference: https://akamai.ferndocs.com/edge-workers/api/edge-workers-api/revisions/post-revision-compare

## Request

### Path parameters

- `edgeWorkerId` (string, required)
- `revisionId` (string, required)

### Query parameters

- `accountSwitchKey` (string, optional) — For customers who manage more than one account, this [runs the operation from another account](https://techdocs.akamai.com/developer/docs/manage-many-accounts-with-one-api-client). The Identity and Access Management API provides a [list of available account switch keys](https://techdocs.akamai.com/iam-api/reference/get-client-account-switch-keys).

### Body (application/json)

This endpoint expects an object.

- `revisionId` (string, required) — Unique identifier of the revision.

## Response

### 200

Provides dependency differences between two revisions.

- `dependencies` (IdsEdgeWorkerIdRevisionsRevisionIdComparePostResponsesContentApplicationJsonSchemaDependencies, required) — EdgeWorker dependencies.
- `edgeWorkerId` (integer, required) — Unique identifier of the EdgeWorker.
- `version` (string, required) — Unique identifier of the version.
- `previousVersion` (string, optional) — Unique identifier of the previous version.

## Types

### IdsEdgeWorkerIdRevisionsRevisionIdComparePostResponsesContentApplicationJsonSchemaDependencies

EdgeWorker dependencies.

- `dependencies` (IdsEdgeWorkerIdRevisionsRevisionIdComparePostResponsesContentApplicationJsonSchemaDependenciesDependencies, required) — EdgeWorker dependencies. This is a further nested revision compare object.
- `edgeWorkerId` (integer, required) — Unique identifier of the EdgeWorker.
- `version` (string, required) — Unique identifier of the version.
- `previousVersion` (string, optional) — Unique identifier of the previous version.
