To allow your users to authenticate to Private Packagist Self-Hosted with their GitLab account, you'll first need to create an integration in Private Packagist. This document walks you through the required steps.

Open the Add Integration form

Go to the Admin section and hit the “Add Integration“ button to open the form to create your integration. If you've just installed Private Packagist Self-Hosted and it is still running in Setup Mode, you do not need to log in. If the application is no longer in Setup mode, you will have to log in with an admin account first.

To set up a GitLab integration with Private Packagist start by selecting "GitLab" as the platform and enter the URL of your own GitLab server or use https://gitlab.com for the public GitLab server as seen in the example below. A link to set up the OAuth application on GitLab will automatically be displayed.

Create a GitLab OAuth Application

Do not submit the integration form yet, but copy the content from the "Callback URL / Redirect URL" and follow the setup link to your GitLab server. The fields Client ID and Client Secret remain empty for now.

Make sure the api and read_user scopes are both checked and save the new application. This will reveal the credentials required to finish the setup on Private Packagist.

Instead of the user settings, you can also create an application in the settings section of a GitLab group, or if you have full admin access on GitLab in the GitLab admin section under Applications. There are two additional checkmarks on that page: trusted should remain unchecked, and confidential should remain checked.

Create the integration

Copy and paste the "Application Id" and "Secret" value back into the Private Packagist integration form and submit the form with the "Create Integration" button.

The GitLab integration will be created and you will be redirected to the admin page.

The new integration will be shown in the list of available integrations, and your users can now log in to your Private Packagist Self-Hosted installation using their GitLab account.
