Promote a build into this workspace

POST /api/v1/projects/{id}/workspaces/{workspace_id}/promotions
Bearer auth

Copies an existing succeeded build's image from another workspace in the same org into this workspace and creates a deployable build. Requires deployment management on both the source build's project and the target project; force additionally requires the target project owner role. Processing is asynchronous — poll the returned promotion until ready or failed.

Path parameters

  • id string Required

    Target project ID

  • workspace_id string Required

    Target workspace ID

application/json

Body Required

Promotion request

  • confirmed boolean Required

    Confirmed must be true: promotion copies an artifact into another project, so the API requires the explicit confirmation the CLI/UI collect from the user.

  • force boolean

    Force bypasses ECP's deploy-proof gate; requires the target project owner role.

  • source_build_id string Required

    SourceBuildID identifies the succeeded build to promote. It may live in any project of the caller's org.

    Unsupported or malformed API version, an operation unavailable in the selected published contract, or an unacceptable representation (including unsupported media-type parameters or excluded SSE). Existing authentication, authorization, and rate-limit failures take precedence.
