# API Reference


This section documents the CloudSigma API. Set `CLOUDSIGMA_API_BASE` to the API endpoint for the region that contains your workspace. Read [Endpoints & Authentication](https://omnifabric.cloudsigma.com/docs/developer/endpoints-and-authentication.html.md) first, then open an operation page for its request and response contract.
For task-based examples and request sequences, see [API](https://omnifabric.cloudsigma.com/docs/developer/api/index.html.md).

## Notes

1. Each page documents a source-confirmed public API operation. Use the exact request and response fields on that page rather than inferring a contract from a console workflow.
2. Use the regional service URL and credentials for the region that contains the target workspace.
