If your company uses GitHub Enterprise Cloud with data residency — where your organization lives on a dedicated *.ghe.com subdomain (for example acme.ghe.com) instead of github.com — you can connect Checksum directly from Settings → Git Integration. The setup is self-serve, takes about two minutes, and installs a Checksum GitHub App on your own instance — you grant access through the app, with no tokens or secrets to share.
This page is for GitHub Enterprise Cloud with data residency (*.ghe.com). If your team is on standard github.com, follow Git Integration instead. GitHub Enterprise Server (self-hosted, e.g. github.your-company.com) is not supported yet.

​
Before you start

You’ll need:
Make sure you’re signed in to GitHub as a member of your *.ghe.com enterprise (not github.com) in the same browser before you start — the flow opens a page on your enterprise instance.

​
Connect your instance

Checksum connects to your repositories through a GitHub App that lives on your own enterprise instance. You create and install it once — there are no tokens to copy or secrets to paste.
1

Open Git Integration

In the Checksum web app, go to Settings → Git Integration and find the repository you want to connect — Tests Repository (where Checksum opens pull requests) or Code Repository (read by agents for better test detection). Each section has its own connection, so repeat this flow for both if you need them.

Click “Connect GitHub Enterprise (ghe.com)”

Under Using a private GitHub Enterprise instance?, click Connect GitHub Enterprise (ghe.com). A Connect GitHub Enterprise dialog opens.
3

Enter your host and organization

Fill in the two fields and click Continue:
Connect GitHub Enterprise dialog — host and organization
4

Create the app on your instance

Click Open GitHub. A page opens on your enterprise instance to register the Checksum AI Code (or Checksum AI Tests) app — Checksum has already set the permissions and webhook, so there’s nothing to configure. Confirm the app name and click Create GitHub App. GitHub then shows the new app with an Install button.
This step only registers the app. It does not grant access to any repositories yet — you choose those in the next step.
Use Open GitHub to launch the page so the app is created with Checksum’s settings. If you land on the wrong GitHub account, the button is a real link — right-click to copy it or open it in a new tab where you’re signed in as an organization owner of your enterprise.

Install the app and choose repositories

Click Install on the app page. GitHub shows the install page, where you choose which repositories Checksum can access:
  • All repositories — every repository in the organization.
  • Only select repositories — pick specific repositories (you can add more later).
Click Install. GitHub redirects you back to Checksum, and Settings → Git Integration shows the enterprise integration as connected.

If the GitHub tab closed before you finished, reopen the dialog and use Reopen GitHub tab to return to the same page.

​
After you’re connected

Once the integration shows as connected, select which repository Checksum should use under Tests Repository and, optionally, Code Repository — exactly as you would for a github.com connection. See Connecting Your Repositories. From there, Checksum can generate and heal tests and open pull requests against your enterprise repositories.

​
Troubleshooting

If GitHub says you don’t have permission, you’re either not an organization owner, or you’re signed in to the wrong GitHub account. Confirm you’re signed in as a member of your *.ghe.com enterprise with the organization owner role, then reopen the GitHub tab. On shared machines, opening the link in a fresh browser profile or incognito window signed in to the right account usually resolves it.
The host must end in .ghe.com, such as acme.ghe.com — that’s the only requirement. You can paste a full URL if you prefer; the field automatically strips https://, any path, and the port. If it’s still rejected, the value doesn’t end in .ghe.com — a GitHub Enterprise Server hostname like github.your-company.com won’t work.
Make sure you clicked Install (not just Create GitHub App) and selected at least one repository. Then refresh Settings → Git Integration. If it still doesn’t appear, reopen the dialog and run the flow again — it’s safe to repeat.
Self-hosted GitHub Enterprise Server (for example github.your-company.com) isn’t supported yet — only GitHub Enterprise Cloud with data residency (*.ghe.com). Contact Checksum support to discuss options.
