Configuring plugin-manifest.json


Here's a sample JSON descriptor file for your reference.

Now we'll see how to define the properties of this file.


The language the extension supports. Currently, we support the locale "en" (English) only.


Name of the Zoho product for which the extension is created. Here, it is "PROJECTS".


If this setting is true, storage space will be allocated in the product for this extension. By default, the value will be false.
  • true
  • false


The domains specified in this array can be called from the extension. Calls to other domains, except the ones with which a connection is established, will not be handled from the extension. If your extension doesn't use any third-party service, then this array can be declared empty.


Modules of the extension. We support widgets currently.


"name":"GDrive for Zoho Projects",
"countkey" : "extensionUniqueKey"


This key holds an array of objects. Every object has three keys - 'location', 'name', and 'URL'.
KeyTypeObject Details

  • task_tab
  • issue_tab
  • app_settings
  • top_band
  • attachment_picker

Note: The location name must be unique.

nameStringThe name of the widget.Example: Checklist

StringUnique id to retrieve the widget count.extensionUniqueKey

An extension can have multiple widgets.
Note: extensionUniqueKey is used to store/update the extension data.


Like widgets, this key also holds an array of objects. A connector helps to integrate an extension with a third-party service. Authorization of such third-party services is usually handled by Zoho Projects.

The value of the connectionLinkName param generated in the JSON tab of the connection summary.

  • true

 ScopeJSONArrayThe access privilege set for the users/admins.Example: [""]

An extension can be connected to a maximum of 5 third-party services at once.


This key can be used when you have to get more inputs from the user to operate the extension. Say, you need the user's domain name of a third-party service for your extension to function. To fetch it, you can use this key to get input from the user accordingly.
