# Configuring a Google Calendar plugin for Amazon Q Business
<a name="gcal-actions"></a>

Google Calendar is an online calendar service that helps users schedule meetings, set up events, set reminders, and share their schedules. If you’re a Google Calendar user, you can create an Amazon Q Business plugin to allow your end users to find and list events from within their web experience chat.

To create a Google Calendar plugin, you need configuration information from your Google Calendar instance to set up a connection between Amazon Q and Google Calendar and allow Amazon Q to perform actions in Google Calendar. 

For more information on how to use plugins during your web experience chat, see [Using plugins](https://docs.aws.amazon.com/amazonq/latest/qbusiness-ug/using-plugins.html).

## Prerequisites
<a name="gcal-plugin-prereqs"></a>

Before you configure your Amazon Q Google Calendar plugin, you must do the following:
+ As an admin, create a new OAuth 2.0 Google Calendar app in the Google Calendar developer console with scoped permissions for performing actions in Amazon Q. To learn how to do this, see [Using OAuth 2.0 to Access Google APIs](https://developers.google.com/identity/protocols/oauth2) in Google Calendar Developer Documentation.
+ Make sure you've added following required scopes: `calendar.readonly`, `calendar.events`.
+ Note the domain URL of your Google Calendar instance. For example: `https://www.googleapis.com/calendar/v3`.
+ Note your:
  + **Access token URL** – For Google Calendar OAuth applications, this is `https://oauth2.googleapis.com/token`.
  + **Authorization URL** – For Google Calendar OAuth applications, this is `https://accounts.google.com/o/oauth2/v2/auth`.
  + **Redirect URL** – The URL to which user needs to be redirected after authentication. If your deployed web url is `<q-endpoint>`, use `<q-endpoint>/oauth/callback` . Amazon Q Business will handle OAuth tokens in this URL. This callback URL needs to be allowlisted in your third-party application.
  + **Client ID** – The client ID generated when you create your OAuth 2.0 application in Google Calendar.
  + **Client secret** – The client secret generated when you create your OAuth 2.0 application in Google Calendar.

  You will need this authentication information during the plugin configuration process.

## Service access roles
<a name="gcal-plugin-iam"></a>

To successfully connect Amazon Q to Google Calendar, you need to give Amazon Q the following permission to access your Secrets Manager secret to get your Google Calendar credentials. Amazon Q assumes this role to access your Google Calendar credentials.

The following is the service access IAM role required:

```
{
    "Version": "2012-10-17",		 	 	 
    "Statement": [{
            "Effect": "Allow",
            "Action": [
                "secretsmanager:GetSecretValue"
            ],
            "Resource": [
                "arn:aws:secretsmanager:{{your-region}}:{{your-account-id}}:secret:[[secret-id]]"
            ]
        }
    ]
}
```

To allow Amazon Q to assume a role, use the following trust policy:

```
{
  "Version": "2012-10-17",		 	 	 
  "Statement": [
    {
      "Sid": "QBusinessApplicationTrustPolicy",
      "Effect": "Allow",
      "Principal": {
        "Service": "qbusiness.amazonaws.com"
      },
      "Action": "sts:AssumeRole",
      "Condition": {
        "StringEquals": {
          "aws:SourceAccount": "{{source_account}}"
        },
        "ArnLike": {
          "aws:SourceArn":"arn:aws:qbusiness:{{your-region}}:{{source_account}}:application/{{application_id}}"
        }
      }
    }
  ]
}
```

If you use the console and choose to create a new IAM role, Amazon Q creates the role for you. If you use the console and choose to use an existing secret, or you use the API, make sure your IAM role contains these permissions. 

## Creating a plugin
<a name="gcal-plugin-create"></a>

To create a Google Calendar plugin for your web experience chat, you can use the AWS Management Console or the [https://docs.aws.amazon.com/amazonq/latest/api-reference/API_CreatePlugin.html](https://docs.aws.amazon.com/amazonq/latest/api-reference/API_CreatePlugin.html) API operation. The following tabs provide a procedure for creating a Google Calendar plugin using the console and code examples for the AWS CLI.

------
#### [ Console ]

**To create a Google Calendar plugin** 

1. Sign in to the AWS Management Console and open the Amazon Q console.

1. From the Amazon Q console, in **Applications**, select the name of your application from the list of applications.

1. From the left navigation menu, choose **Actions**, and then choose **Plugins**.

1. For **Plugins**, choose **Add plugin**.

1. For **Add plugins**, choose **Google Calendar**.

1. For **Google Calendar**, enter the following information:

   1. In **Plugin name**, for **Name** – A name for your Amazon Q plugin. The name can include hyphens (-), but not spaces, and can have a maximum of 1,000 alphanumeric characters.

   1. In **Domain URL**, for **URL** – Enter your Google Calendar domain URL. For example, `https://www.googleapis.com/calendar/v3`.

   1. **OAuth 2.0 authentication** – do the following:

      1. For **AWS Secrets Manager secret** – Choose **Create and add a new secret** or **Use an existing one**. Your secret must contain the following information:
         + **Secret name** – A name for your Secrets Manager secret.
         + **Client ID** – The client ID generated when you create your OAuth 2.0 application in Google Calendar.
         + **Client secret** – The client secret generated when you create your OAuth 2.0 application in Google Calendar.
         + For **Redirect URL** – The URL to which user needs to be redirected after authentication. If your deployed web url is `<q-endpoint>`, use `<q-endpoint>/oauth/callback` . Amazon Q Business will handle OAuth tokens in this URL. This callback URL needs to be allowlisted in your third-party application.

      1. For **Access token URL** – For Google Calendar OAuth applications, this is `https://oauth2.googleapis.com/token`.

      1. For **Authorization URL** – For Google Calendar OAuth applications, this is `https://accounts.google.com/o/oauth2/v2/auth`.

   1. **Service access** – Choose **Create and add a new service role** or **Use an existing service role**. Make sure tha your service role has the necessary permissions.

1. **Tags – *optional*** – An optional tag to track your plugin.

1. Choose **Save**.
