Composer API (FREE)

This is the API documentation for Composer Packages.

WARNING: This API is used by the Composer package manager client and is generally not meant for manual consumption.

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

NOTE: These endpoints do not adhere to the standard API authentication methods. See the Composer package registry documentation for details on which headers and token types are supported.

Base repository request

Returns the repository URL templates for requesting individual packages:

GET group/:id/-/packages/composer/packages

Attribute	Type	Required	Description
id	string	yes	The ID or full path of the group.

curl --user <username>:<personal_access_token> "https://gitlab.example.com/api/v4/group/1/-/packages/composer/packages"

Example response:

{
  "packages": [],
  "metadata-url": "/api/v4/group/1/-/packages/composer/p2/%package%.json",
  "provider-includes": {
    "p/%hash%.json": {
      "sha256": "082df4a5035f8725a12i4a3d2da5e6aaa966d06843d0a5c6d499313810427bd6"
    }

{
  "packages": [],
  "metadata-url": "/api/v4/group/1/-/packages/composer/p2/%package%.json"
