About URL parameters for registering GitHub Apps

You can use URL parameters to preselect the configuration settings of a new GitHub App registration and share a custom link with other people. The link will take people to a GitHub App registration page, where the app settings will be pre-filled according to the URL parameters you included in the URL.

This approach is useful for integrators who want customers to set up an app on their personal account or organization with certain specifications, or for customers using GitHub Enterprise Server who aren't able to install apps from the GitHub Marketplace.

Alternatively, you can create a GitHub App manifest. For more information, see Registering a GitHub App from a manifest.

Creating a custom configuration URL with query parameters

To create a custom configuration URL for a GitHub App on a personal or organization account, add query parameters after the following base URLs.

• To register an app on a personal account, add URL parameters to: https://github.com/settings/apps/new
• To register an app on an organization account, add URL parameters to: https://github.com/organizations/ORGANIZATION/settings/apps/new. Replace ORGANIZATION with the name of the organization where you'd like the customer to register the app.

On the app registration page, the person registering the app can edit the preselected values before submitting the app. If you do not include parameters for required values (like name) in the URL query string, the person registering the app will need to input a value before they can register the app.

For example, the following URL registers a new public app named octocat-github-app on a personal account. Using query parameters, the URL preconfigures a description and a callback URL. It also selects read and write permissions for checks, activates webhooks using the webhook_active parameter, subscribes to the check_run and check_suite webhook events, and selects the option to request user authorization (OAuth) during installation:

https://github.com/settings/apps/new?name=octocat-github-app&description=An%20Octocat%20App&callback_urls[]=https://example.com&request_oauth_on_install=true&public=true&checks=write&webhook_active=true&events[]=check_run&events[]=check_suite

GitHub App configuration parameters

You can use the following query parameters to select a specific configuration for the GitHub App registration. For example, to name the app "octocat-github-app", your query string would include name=octocat-github-app.

Parameter name	Type	Description
name	string	The name of the GitHub App. Give your app a clear and succinct name. Your app cannot have the same name as an existing GitHub user, unless it is your own user or organization name. A slugged version of your app's name will be shown in the user interface when your integration takes an action.
description	string	A description of the GitHub App.
url	string	The full URL of your GitHub App's website homepage.
callback_urls	array of strings	A full URL to redirect to after someone authorizes an installation. You can provide up to 10 callback URLs. These URLs are used if your app needs to generate a user access token. For example, callback_urls[]=https://example.com&callback_urls[]=https://example-2.com. For more information, see About the user authorization callback URL.
request_oauth_on_install	boolean	If your app authorizes users using the OAuth flow, you can set this option to true to allow people to authorize the app when they install it, saving a step. If you select this option, the setup_url becomes unavailable and users will be redirected to your callback_url after installing the app.
setup_url	string	The full URL to redirect to after someone installs the GitHub App if the app requires additional setup after installation. For more information, see About the setup URL.
setup_on_update	boolean	Set to true to redirect people to the setup URL when installations have been updated, for example, after repositories are added or removed.
public	boolean	Set to true when your GitHub App is available to the public or false when it is only accessible to the owner of the app. This parameter does not apply to apps owned by enterprises.
webhook_active	boolean	Set to true to enable webhook. Webhook is disabled by default.
webhook_url	string	The full URL that you would like to send webhook event payloads to.
events	array of strings	Webhook events. Some webhook events require read or write permissions for a resource before you can select the event when registering a new GitHub App. For more information, see the GitHub App webhook events section. You can select multiple events in a query string. For example, events[]=public&events[]=label.
single_file_name	string	This is a narrowly-scoped permission that allows the app to access a single file in any repository. When you set the single_file permission to read or write, this field provides the path to the single file your GitHub App will manage. If you need to manage multiple files, see single_file_paths below.
single_file_paths	array of strings	This allows the app to access up ten specified files in a repository. When you set the single_file permission to read or write, this array can store the paths for up to ten files that your GitHub App will manage. These files all receive the same permission set by single_file, and do not have separate individual permissions. When two or more files are configured, the API returns multiple_single_files=true, otherwise it returns multiple_single_files=false.

GitHub App permissions

You can use query parameters to select the permissions for the GitHub App registration. For the URL query parameter, use the permission name as the query parameter name, and set the query value to one of the possible values for that permission set.

For example, to select "Read & write" permissions in the user interface for contents, your query string would include contents=write. To select "Read-only" permissions in the user interface for blocking, your query string would include blocking=read. To select "No access" in the user interface for checks, your query string would not include the checks permission.

For more information about permissions and GitHub Apps, see Choosing permissions for a GitHub App. To see the list of permissions available for use and their parameterized names, see Managing your personal access tokens.

GitHub App webhook events

You can use query parameters to enable the GitHub App webhook, designate a webhook URL, and subscribe the app to receive webhook payloads for specific events.

To enable the GitHub App webhook, use webhook_active=true in your query string. To designate a full URL that you would like to send webhook event payloads to, use webhook_url in your query string. To subscribe the app to specific webhook payload events, use events[] as the query parameter name, and set the query value to the name of the webhook event. For more information about the possible webhook events and the GitHub App permissions required to subscribe to each event, see Webhook events and payloads.

For example, to subscribe a GitHub App to receive webhook payloads for activity relating to commit comments, the query string would include &webhook_active=true&webhook_url=https://example.com&events[]=commit_comment. Note that the commit_comment webhook event requires the GitHub App to have at least read-level access for the "Contents" repository permission. So your query string should also include a parameter to set the contents permission to read or write. For more information, see GitHub app permissions.

You cannot use query parameters to set the value of a webhook secret. If an app requires a secret to secure its webhook, the value of the secret must be set in the GitHub UI by the person registering the app.
