# Create Workflow Variant

`POST /workflows/variants/`

Create a new variant under an existing workflow.

Variants are branches of an artifact's history; each maintains its own
revision log. Variant slugs are unique within the project — reuse of a
slug already in use returns a 409 conflict.

See: [Versioning](/reference/api-guide/versioning).
