The app descriptor is one of the essential building blocks of Crowdin apps. The app descriptor is a JSON file (for example, crowdin.json) that includes general information for the app, as well as the modules that the app wants to operate with or extend. It describes how the application will work, what resources will be used, etc. You can see an example below.

Specifies the authentication type to use when signing requests from the host application to the Crowdin app. Crowdin Apps support two types of authentication:
authorization_code value)none value)In case your Crowdin app requires access to Crowdin API at any time, it’s recommended to use the authorization_code, in other cases feel free to use the none. The authentication type none grants access to Crowdin API as well as the authorization_code, but only when the Crowdin app is executed on the user side, for example, when the iframe opens.

Allow an app to register callbacks for events that occur in the workspace. When an event is fired, a POST request will be made to the appropriate URL registered for the event. The installed callback is an integral part of the installation process of an app, whereas the remaining events are essentially webhooks. Each property within this object is a URL relative to the app’s base URL.
Esempio:
{
"events": {
"installed": "/hook/installed",
"uninstall": "/hook/uninstall"
}
}
Properties:
installed | Type: Description: The event that is sent to an app after a user installed the app in Crowdin Enterprise. This event is required if you use |
uninstall | Type: Description: The event that is sent to an app before the app uninstallation from Crowdin Enterprise. |
Installed event
The Installed event is sent from Crowdin Enterprise to the remote Crowdin app when a user installs the app in Crowdin Enterprise. The Installed event contains the information about the Crowdin Enterprise workspace the Crowdin App was installed to, the information about the app itself, as well as the app authorization_code. As soon as the authorization_code is received it’s necessary to authorize the app using the access and refresh tokens.

Uninstall event
The uninstall event is sent from Crowdin Enterprise to the remote Crowdin app when a user uninstalls the app from Crowdin Enterprise. The Uninstall event, like the install event, contains the information about the Crowdin Enterprise workspace the Crowdin App was installed to, and the information about the app itself. After receiving the uninstall event, it’s necessary to find and remove all of the data related to the Crowdin Enterprise workspace the app is removed from.
