Compare scenario versions

GET /api/v1/script-versions/{version}/diff

Compare two versions of the same scenario, or compare against the published version.

Access

A Bearer API key for this workspace is required; a read-only key is sufficient. The server also checks the owner’s permission for this resource and action. An inaccessible object is not disclosed.

Parameters

Path parameters: version. Use IDs from your own installation.

Example request parameters or JSON body:

{
  "against": 2
}

against must belong to the same scenario. If no comparison version exists, the server returns 422 no_counterpart.

Response 200

The example is shortened; actual responses may include more fields. Sample IDs are placeholders.

{
  "from": {
    "id": 2,
    "number": 1
  },
  "to": {
    "id": 3,
    "number": 2
  },
  "identical": false
}

Send the request

Set BASE to your installation URL without a trailing slash and API_KEY to a secret stored on your server. Client setup and browser JavaScript.
