# Terraform provider

Use the official [Harness Terraform provider](https://registry.terraform.io/providers/harness/harness/latest/docs) to manage Harness resources as code. The provider supports creating and managing environments, traffic types, segments, feature flags, flag sets, and API keys.

### Resources <a href="#resources" id="resources"></a>

The following Harness FME resources are available in the Harness Terraform provider.

#### Feature flags <a href="#feature-flags" id="feature-flags"></a>
