Revisions

Dataset revisions preserve table snapshots when columns or rows change.

Endpoints

Method	Path	Purpose
GET	/datasets/{dataset_id}/revisions	List revisions.
GET	/datasets/{dataset_id}/revisions/{revision_number}	Get a specific revision.

List Revisions

GET /api/v1/datasets/{dataset_id}/revisions

Use this endpoint to inspect historical table versions, audit data changes, or select a revision to pin in a test case binding.

Get Revision

GET /api/v1/datasets/{dataset_id}/revisions/{revision_number}

Revision responses include the revision number, change summary, columns, rows, creation metadata, and whether the revision is current.

follow_latest bindings use the dataset's current revision. pin_revision bindings keep using the specified revision until the binding is changed.

Required Permissions

Unless a more specific rule is stated above, read endpoints require viewer, create and update endpoints require tester, and destructive endpoints require lead or the stricter role enforced by the owning service.

Request and Response Schemas

Use the examples on this page together with the generated OpenAPI schema at /docs or /redoc for exact field types. JSON endpoints use application/json; upload endpoints use multipart/form-data; resource ids are passed as path parameters.

Status Codes and Errors

Common responses are 200 for reads and updates, 201 for creates, 204 for successful deletes, 401 for missing authentication, 403 for insufficient project role, 404 for missing or inaccessible resources, and 422 for validation errors.

  "type": "https://tms.local/errors/validation_error",
  "title": "Validation failed",
  "status": 422,

  "code": "validation_error",
  "request_id": "req_123",
  "errors": {
    "field": ["Field is required"]
  }
}

Pagination and Filtering

List endpoints that expose page and page_size use 1-based pagination. Many list endpoints cap page_size at 200; row-oriented endpoints may document a different cap. Filtering examples on this page use repeated query parameters when multiple values are supported.

Idempotency and Retries

GET requests are safe to retry. POST, PATCH, DELETE, bulk operations, and imports are not guaranteed to be idempotent unless the endpoint explicitly says so. After a network timeout on a write request, read the affected resource before retrying.

Limits and Destructive Operations

Karvio does not currently enforce application-level rate limits. File upload limits are documented on upload-specific pages. Delete, archive, unlink, and bulk delete operations can remove data or hide it from active workflows; confirm project scope and permissions before calling them from automation.
