CloudScript quickstart

CloudScript offers a fast, secure and scalable alternative to dedicated servers. Your custom JavaScript lives and executes directly on PlayFab machines.


CloudScript using Azure Functions supports more languages and has improved debugging workflows.

From here, your code can be called directly by your game clients - or indirectly via PlayStream actions. Additionally, CloudScript methods have full access to PlayFab's Server API set.

This quickstart covers uploading and managing your CloudScript files in the PlayFab Game Manager.


The Writing custom CloudScript tutorial covers writing the CloudScript code itself.

Please note the following when reading this:

  • You should be familiar with the basics of PlayFab.
  • The C# samples shown correspond to using the PlayFab Unity SDK.
  • JavaScript samples correspond to using the PlayFab CloudScript service.

Your first CloudScript revision

After creating a title, PlayFab automatically includes an example script as your first revision. This revision includes a number of methods that you can use for learning and testing CloudScript.

To see these functions:

  • Open Game Manager.
  • Select your title.
  • Select Automation on the left side bar.

You should see a number of CloudScript methods - such as HelloWorld, which logs the message Hello PLAYERID - where PLAYERID is the current player's PlayFab ID.

Uploading your own revisions

You can upload your own custom methods via the Game Manager. Each file you upload will create a new revision. During the upload, the PlayFab service runs a simple LINT check over your CloudScript for syntax errors.

If it finds an error:

  • An error message will be displayed.
  • Fix the error, and select SUBMIT again.
  • By default, new uploads must be deployed by selecting the DEPLOY REVISION # TO LIVE link. This enables you to update or roll back to/from multiple versions of CloudScript.

The first time you press the orange UPLOAD NEW REVISION button, you will see a file selector where you can upload a file from your local machine.

Game Manager - Upload CloudScript file

After you have added several revisions, you can select which submitted revision is live with the drop-down.

GitHub integration

You may also use GitHub to manage your CloudScript revisions. You must have a GitHub account, and you must be logged in.

  • Select the USE GITHUB button (the gray button in the previous screenshot).
  • The next window will have an orange AUTHORIZE GITHUB ACCOUNT button.
  • Create a new, empty repository in GitHub.
  • Return to the GitHub page in the PlayFab Game Manager (refresh tab).
  • At this point, you should be able to select your GitHub repository, and bind it to your title.

Once bound to GitHub, the manual upload option is removed, and new CloudScript revisions are automatically made for each GitHub commit to the "master" branch.

If you commit multiple files, they will be concatenated together into a single PlayFab CloudScript revision. Live revision selection remains the same: new commits to GitHub must be set to live in Game Manager as described above.


CloudScript allows you to upload files to PlayFab, and execute your code on our server. You can manage your CloudScript files from the Automation option in the left side bar. You can upload files manually from your own computer, or bind your title to a GitHub account.

This quickstart covers managing your code files and uploading them to PlayFab.
