Google Drive is a cloud-based file storage service. You can use Amazon Kendra to index documents stored in shared drives, My Drives, and Shared with me folders in your Google Drive data source. You can index both Google Workspace documents as well as documents listed in [Types of documentation](https://docs.aws.amazon.com/kendra/latest/dg/index-document-types.html). You can also use inclusion and exclusion filters to index content by file name, file type, and file path.

You can connect Amazon Kendra to your Google Drive data source using the [Amazon Kendra console](https://console.aws.amazon.com/kendra/), the [TemplateConfiguration](https://docs.aws.amazon.com/kendra/latest/APIReference/API_TemplateConfiguration.html) API, or the [GoogleDriveConfiguration](https://docs.aws.amazon.com/kendra/latest/APIReference/API_GoogleDriveConfiguration.html) API.

Amazon Kendra has two versions of the Google Drive connector. Supported features of each version include:

**Google Drive connector V1.0 / [GoogleDriveConfiguration](https://docs.aws.amazon.com/kendra/latest/APIReference/API_GoogleDriveConfiguration.html) API**
+ Field mappings
+ User access control
+ Inclusion/exclusion filters

**Google Drive connector V2.0 / [TemplateConfiguration](https://docs.aws.amazon.com/kendra/latest/APIReference/API_TemplateConfiguration.html) API**
+ Field mappings
+ User access control
+ Inclusion/exclusion filters
+ Full and incremental content syncs
+ Virtual private cloud (VPC)

## Prerequisites


Before you can use Amazon Kendra to index your Google Drive data source, make these changes in your Google Drive and AWS accounts.

**In Google Drive, make sure you have:**
+ **Either** been granted access by a super admin role **or** are a user with administrative privileges. You do not need a super admin role for yourself if you have been granted access by a super admin role.
+ Created a service account with **Enable G Suite Domain-wide Delegation** activated and a JSON key as private key using the account.
+ Copied your user account email and your service account email. When you connect to Amazon Kendra you enter your user account email as admin account email and your service account email as client email in your AWS Secrets Manager secret.
**Note**  
We recommend that you regularly refresh or rotate your credentials and secret. Provide only the necessary access level for your own security. We do **not** recommend that you re-use credentials and secrets across data sources, and connector versions 1.0 and 2.0 (where applicable).
+ Added Admin SDK API and Google Drive API in your account.
+ Added (or asked a user with a super admin role to add) the following permissions to your service account using a super admin role:
  + https://www.googleapis.com/auth/drive.readonly
  + https://www.googleapis.com/auth/drive.metadata.readonly
  + https://www.googleapis.com/auth/admin.directory.user.readonly
  + https://www.googleapis.com/auth/admin.directory.group.readonly
+ Checked each document is unique in Google Drive and across other data sources you plan to use for the same index. Each data source that you want to use for an index must not contain the same document across the data sources. Document IDs are global to an index and must be unique per index.

**In your AWS account, make sure you have:**
+ [Created an Amazon Kendra index](https://docs.aws.amazon.com/kendra/latest/dg/create-index.html) and, if using the API, noted the index ID.
+ [Created an IAM role](https://docs.aws.amazon.com/kendra/latest/dg/iam-roles.html#iam-roles-ds) for your data source and, if using the API, noted the ARN of the IAM role.
**Note**  
If you change your authentication type and credentials, you must update your IAM role to access the correct AWS Secrets Manager secret ID.
+ Stored your Google Drive authentication credentials in an AWS Secrets Manager secret and, if using the API, noted the ARN of the secret.
**Note**  
We recommend that you regularly refresh or rotate your credentials and secret. Provide only the necessary access level for your own security. We do **not** recommend that you re-use credentials and secrets across data sources, and connector versions 1.0 and 2.0 (where applicable).

If you don’t have an existing IAM role or secret, you can use the console to create a new IAM role and Secrets Manager secret when you connect your Google Drive data source to Amazon Kendra. If you are using the API, you must provide the ARN of an existing IAM role and Secrets Manager secret, and an index ID.

You can specify whether to include or exclude certain content in shared drives, user accounts, document MIME types, and files. If you choose to exclude user accounts, none of the files in the My Drive owned by the account are indexed. Files shared with the user are indexed unless the owner of the file is also excluded.
**Note**  
Most data sources use regular expression patterns, which are inclusion or exclusion patterns referred to as filters. If you specify an inclusion filter, only content that matches the inclusion filter is indexed. Any document that doesn’t match the inclusion filter isn’t indexed. If you specify an inclusion and exclusion filter, documents that match the exclusion filter are not indexed, even if they match the inclusion filter.
+  **Field mappings**—Choose to map your Google Drive data source fields to your Amazon Kendra index fields. For more information, see [Mapping data source fields](https://docs.aws.amazon.com/kendra/latest/dg/field-mapping.html).

Before you can use Amazon Kendra to index your Google Drive data source, make these changes in your Google Drive and AWS accounts.

**In Google Drive, make sure you have:**
+ **Either** been granted access by a super admin role **or** are a user with administrative privileges. You do not need a super admin role for yourself if you have been granted access by a super admin role.
+ Configured Google Drive Service Account connection credentials containing your admin account email, client email (service account email), and private key. See [Google Cloud documentation on creating and deleting service account keys](https://cloud.google.com/iam/docs/keys-create-delete).
**Note**  
We recommend that you regularly refresh or rotate your credentials and secret. Provide only the necessary access level for your own security. We do **not** recommend that you re-use credentials and secrets across data sources, and connector versions 1.0 and 2.0 (where applicable).
+ Created a Google Cloud Service Account (an account with delegated authority to assume a user identity) with **Enable G Suite Domain-wide Delegation** activated for server-to-server authentication, and then generated a JSON private key using the account.
**Note**  
The private key should be generated after the creation of the service account.
+ Added Admin SDK API and Google Drive API in your user account.
+ **Optional:** Configured Google Drive OAuth 2.0 connection credentials containing client ID, client secret, and refresh token as connection credentials for a specific user. You need this to crawl individual account data. See [Google documentation on using OAuth 2.0 to access APIs](https://developers.google.com/identity/protocols/oauth2).
+ Added (or asked a user with a super admin role to add) the following OAuth scopes to your service account using a super admin role. These API scopes are needed to crawl all documents, and access control (ACL) information for all users in a Google Workspace domain:
  + https://www.googleapis.com/auth/drive.readonly—View and download all your Google Drive files
  + https://www.googleapis.com/auth/drive.metadata.readonly—View metadata for files in your Google Drive
  + https://www.googleapis.com/auth/admin.directory.group.readonly—Scope for only retrieving group, group alias, and member information. This is needed for the Amazon Kendra Identity Crawler.
  + https://www.googleapis.com/auth/admin.directory.user.readonly—Scope for only retrieving users or user aliases. This is needed for listing users in the Amazon Kendra Identity Crawler and for setting ACLs.
  + https://www.googleapis.com/auth/cloud-platform—Scope for generating access token for fetching content of large Google Drive files.
  + https://www.googleapis.com/auth/forms.body.readonly—Scope for fetching data from Google Forms.

  ** To support the Forms API, add the following additonal scope:**
  + https://www.googleapis.com/auth/forms.body.readonly
+ Checked each document is unique in Google Drive and across other data sources you plan to use for the same index. Each data source that you want to use for an index must not contain the same document across the data sources. Document IDs are global to an index and must be unique per index.

**In your AWS account, make sure you have:**
+ [Created an Amazon Kendra index](https://docs.aws.amazon.com/kendra/latest/dg/create-index.html) and, if using the API, noted the index ID.
+ [Created an IAM role](https://docs.aws.amazon.com/kendra/latest/dg/iam-roles.html#iam-roles-ds) for your data source and, if using the API, noted the ARN of the IAM role.
**Note**  
If you change your authentication type and credentials, you must update your IAM role to access the correct AWS Secrets Manager secret ID.
+ Stored your Google Drive authentication credentials in an AWS Secrets Manager secret and, if using the API, noted the ARN of the secret.
**Note**  
We recommend that you regularly refresh or rotate your credentials and secret. Provide only the necessary access level for your own security. We do **not** recommend that you re-use credentials and secrets across data sources, and connector versions 1.0 and 2.0 (where applicable).

If you don’t have an existing IAM role or secret, you can use the console to create a new IAM role and Secrets Manager secret when you connect your Google Drive data source to Amazon Kendra. If you are using the API, you must provide the ARN of an existing IAM role and Secrets Manager secret, and an index ID.

**Note**  
Most data sources use regular expression patterns, which are inclusion or exclusion patterns referred to as filters. If you specify an inclusion filter, only content that matches the inclusion filter is indexed. Any document that doesn’t match the inclusion filter isn’t indexed. If you specify an inclusion and exclusion filter, documents that match the exclusion filter are not indexed, even if they match the inclusion filter.
+ **Access control list (ACL)**—Specify whether to crawl ACL information for your documents, if you have an ACL and want to use it for access control. The ACL specifies which documents that users and groups can access. The ACL information is used to filter search results based on the user or their group access to documents. For more information, see [User context filtering](https://docs.aws.amazon.com/kendra/latest/dg/user-context-filter.html#context-filter-user-incl-datasources).
+ **Identity crawler**—Specify whether to turn on Amazon Kendra’s identity crawler. The identity crawler uses the access control list (ACL) information for your documents to filter search results based on the user or their group access to documents. If you have an ACL for your documents and choose to use your ACL, you can then also choose to turn on Amazon Kendra’s identity crawler to configure [user context filtering](https://docs.aws.amazon.com/kendra/latest/dg/user-context-filter.html#context-filter-user-incl-datasources) of search results. Otherwise, if identity crawler is turned off, all documents can be publicly searched. If you want to use access control for your documents and identity crawler is turned off, you can alternatively use the [PutPrincipalMapping](https://docs.aws.amazon.com/kendra/latest/APIReference/API_PutPrincipalMapping.html) API to upload user and group access information for user context filtering.
+  **Field mappings**—Choose to map your Google Drive data source fields to your Amazon Kendra index fields. For more information, see [Mapping data source fields](https://docs.aws.amazon.com/kendra/latest/dg/field-mapping.html).
**Note**  
The document body field or the document body equivalent for your documents is required in order for Amazon Kendra to search your documents. You must map your document body field name in your data source to the index field name `_document_body`. All other fields are optional.

For a list of other important JSON keys to configure, see [Google Drive template schema](https://docs.aws.amazon.com/kendra/latest/dg/ds-schemas.html#ds-google-drive-schema).

## Notes

+ Custom field mapping is not available for Google Drive connector as the Google Drive UI does not support creating custom fields.
+ Google Drive API does not support retrieving comments from a permamently deleted file. Comments are retrievable, however, for trashed files. When a file is trashed, the Amazon Kendra connector will delete comments from the Amazon Kendra index.
+ Google Drive API does not return comments present in a .docx file.
+ If permission for a particular Google document (document, spreadsheet, slide, etc) is set to **General access: Anyone with the link** or **Shared to your specific company domain**, the document will not be visible to Amazon Kendra search users until the user making the query has accessed the document.
