Composer API

This is the API documentation for Composer Packages.

caution
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. Undocumented authentication methods might be removed in the future.

Base repository request

GET group/:id/-/packages/composer/packages
AttributeTypeRequiredDescription
idstringyesThe 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"
    }
  },
  "providers-url": "/api/v4/group/1/-/packages/composer/%package%$%hash%.json"
}

This endpoint is used by Composer V1 and V2. To see the V2-specific response, include the Composer User-Agent header. Using Composer V2 is recommended over V1.

curl --user <username>:<personal_access_token> \
     --header "User-Agent: Composer/2" \
     "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"
}
