Helm API

Tier: Free, Premium, Ultimate
Offering: GitLab.com, GitLab Self-Managed, GitLab Dedicated

This is the API documentation for Helm.

This API is used by the Helm-related package clients such as Helm and helm-push, and is generally not meant for manual consumption.

For instructions on how to upload and install Helm packages from the GitLab package registry, see the Helm registry documentation.

These endpoints do not adhere to the standard API authentication methods. See the Helm registry documentation for details on which headers and token types are supported. Undocumented authentication methods might be removed in the future.
