A plug-in is a package of HTML, JavaScript, and CSS files for setting screens.
Using plug-ins on Kintone allows you to extend the functionality of your apps.
The steps to use a plug-in are as follows.

Step 1: Add the plug-in in Kintone Administration
Step 2: Add and set up the plug-in on individual apps

This article covers Step 1, adding plug-ins in Kintone Administration, as well as how to delete plug-ins in Kintone Administration.
For details on Step 2, adding plug-ins to apps, refer to the following page.
Adding/Deleting Plug-Ins (App Settings)

To use plug-ins provided by developers, such as Kintone development partners, add the plug-ins to Kintone by importing them from plug-in files. Do not import any plug-in files unless you trust the source.

1. Click the Settings icon (the gear-shaped icon) at the top of Kintone, then select Kintone Administration.
   Opening the Kintone Administration Screen

2. Click Plug-ins under Other.

3. Click Import at the upper left of the screen.

4. Click Browse and select the plug-in file to import ("***.zip").

   • Import the plug-in file in zip format.
   • The maximum file size for a plug-in file that can be imported is 100 MB.

5. Click Import.

When the plug-in appears in the Imported Plug-ins list, it means that the plug-in has been successfully added.
If you want to update the imported plug-in, import the latest version of the plug-in file. The steps to import the file are the same as the steps to import a new plug-in file.

After the plug-in is added by a Kintone Administrator, app administrators need to add the plug-in in the App Settings of individual apps.
Adding/Deleting Plug-Ins (App Settings)

To delete a plug-in, click the Delete icon (the trash can-shaped icon to the right of the plug-in) on the "Plug-ins" screen of Kintone Administration.
Then, click Uninstall. This deletes the added plug-in.

To delete plug-ins from individual apps, click the Remove icon at the right of the plug-ins on the "Plug-ins" screen of each individual app's App Settings.
