# API

Use the CloudSigma HTTP API to manage workspace resources. These pages organize the API by development task; each task page links to the field-level API Reference for exact methods, parameters, and response schemas.

## Before you call

- Use the API base URL for the region that contains the target workspace.
- Pass a personal access token in `X-API-Key`.
- Pass the target workspace ID in `X-Workspace-ID` for workspace-scoped operations.
- Keep resource IDs and run IDs returned by create or execute operations; later status and result requests use those identifiers.
