to make an application appear under settings then- applications then in- installed github apps, it must be successfully installed on your account

and If you are using a third-party app: Go to the application's public landing page or the GitHub marketplace

Hi @YaricheK2009,

From your screenshot, the apps listed (ChatGPT Codex Connector, Railway App) are third-party apps. You don't create those. They appear in Installed GitHub Apps after you approve their install on your account, usually when you click "Connect GitHub" inside that service, or from its GitHub Marketplace page. Approve it for your account and the repos you pick, and it shows up under Settings > Applications > Installed GitHub Apps.

If you want your own app to appear there:

1. Settings > Developer settings > GitHub Apps > New GitHub App.
2. Give it a unique name and a Homepage URL (your repo or profile URL is fine).
3. Untick "Active" under Webhook if you don't need webhooks.
4. Pick only the permissions it needs, then click Create GitHub App.
5. Creating it doesn't install it. In Developer settings > GitHub Apps click Edit next to your app, then Install App > Install next to your account, choose the repos, and confirm.

Hi @YaricheK2009!

To answer your question directly: You do not need to create your own GitHub App if you just want to use third-party tools like ChatGPT Codex Connector or Railway (shown in your screenshot). Those are external services that you simply install.

Here is a clear explanation of how both options work:

Option 1: Installing an Existing Third-Party App (What is shown in your screenshot)

Apps like ChatGPT Codex Connector and Railway are created and hosted by external providers. To install them:

1. From GitHub Marketplace:
   • Go to GitHub Marketplace.
   • Search for the application you want (e.g., Railway, Slack, Sentry, etc.).
   • Click on the app, select a plan (many have free plans), and click Install or Set up a new plan.
2. From the Service's Website:
   • When you sign up for tools like Railway or connect an AI assistant, they will provide a "Connect with GitHub" or "Install GitHub App" button.
3. Granting Access:
   • GitHub will prompt you to choose where to install it: All repositories or Only select repositories.
   • Click Install & Authorize.
4. Once completed, the app will immediately appear under Settings → Applications → Installed GitHub Apps.

Option 2: Creating and Installing Your Own Custom GitHub App

If you are developing your own custom bot, script, or automated tool and want it to appear in that section:

1. Click your profile photo (top right) → Settings.
2. In the left sidebar, scroll down to the bottom and click Developer settings (or visit github.com/settings/apps).
3. Under GitHub Apps, click New GitHub App.
4. Fill in the required fields:
   • GitHub App name: A unique name for your application.
   • Homepage URL: Your project URL or website (e.g., https://github.com/your-username).
   • Webhook: If you don't have a live webhook server yet, uncheck Active.
5. Set the Permissions your app requires (e.g., Repository permissions → Contents or Issues).
6. Under "Where can this GitHub App be installed?", select Only on this account.
7. Click Create GitHub App.
8. Crucial step to make it appear under Installed GitHub Apps:
   • On the left sidebar of your newly created app settings, click Install App.
   • Click the green Install button next to your account.
   • Choose your repository access permissions and click Install.

Now, your custom app will also be listed under Settings → Applications → Installed GitHub Apps!

Summary

• If you want to use existing integrations (like in your screenshot), install them from the service or GitHub Marketplace.
• If you are building your own tool, create it in Developer Settings and then click "Install App" to install it onto your account.

Hi @YaricheK2009,

The important distinction is that creating a GitHub App and installing a GitHub App are two separate steps.

• If you want to use an existing app (such as a third-party integration), find its official website or GitHub Marketplace listing and choose its GitHub installation or connection option. Review the requested permissions and select the repositories it can access before approving.
• If you want to create your own app, go to [GitHub Developer Settings](https://github.com/settings/apps), select New GitHub App, configure its name, homepage, and only the permissions it needs, then create it.
• After creating your own app, open its settings and select Install App. Choose your account, select the repositories it should access, and confirm the installation.

Once installed, you can check Settings → Applications → Installed GitHub Apps.

One important security tip: grant access only to the repositories and permissions the app actually needs. Also, registering an app alone won't make it appear in the installed-apps list — it must be installed separately.

Official documentation:

• [Registering a GitHub App](https://docs.github.com/en/apps/creating-github-apps/registering-a-github-app/registering-a-github-app)
• [Installing your own GitHub App](https://docs.github.com/en/apps/using-github-apps/installing-your-own-github-app)

Hello

To solve this problem completely you must make sure that you register the app blueprint inside developer settings and then execute the separate install step onto your profile.

First click your profile picture in the upper right corner and select settings.
Next scroll down the left sidebar and click developer settings.
Then choose GitHub apps and click new GitHub app.
Fill in the unique name and homepage URL fields.
Uncheck active under webhooks if you do not have a live server.
Set the minimum necessary repository permissions and click create GitHub app.
Now click install app in the left menu of the settings page for your new app.
Click the green install button next to your account. Select all repositories or only specific repositories.
Click the final install confirmation button.

Executing these steps generates the active installation tokens that force the application out of developer mode and places it under your installed GitHub apps page. In conclusion registering the app only saves the design layout while the installation step creates the functional connection required to display the application in your final account dashboard.

With kind regards,

Yes, you can do either.

To install an existing app: visit the app's website or GitHub Marketplace page and choose Install GitHub App or Connect GitHub. After approving the requested permissions and selecting repositories, the app will appear under Settings → Applications → Installed GitHub Apps.

To create your own app: go to Settings → Developer settings → GitHub Apps → New GitHub App, configure the app, and create it. However, creating the app alone is not enough. You must then open the app's settings and choose Install App to install it on your account. Only after installation will it appear under Installed GitHub Apps.

In short: Create ≠ Install. A GitHub App appears in Installed GitHub Apps only after it has been installed on an account or organisation
