# Ruby SDKs

Use the IONOS Cloud Ruby SDK to automate IONOS Cloud from Ruby apps and scripts.

### When to use the Ruby SDK

* Automation scripts and internal tooling.
* Integrations with Ruby services.
* Prototyping workflows quickly.

### Prerequisites

* An IONOS Cloud account.
* API access for your tenant.

### Authentication

Use the same credentials you use for the IONOS Cloud API.

Use environment variables or a secret manager.

### Common workflows

* Provision and tear down environments.
* Manage networking and storage operations.
* Build small tools for developers and operators.

### Troubleshooting

* Check credentials, permissions, and API reachability.
* Add retries for transient network errors.

### Next steps

* Use the REST API for direct HTTP usage.
* Use an IaC tool for repeatable provisioning.
