## URI Request Parameters
The request does not use any URI parameters.
## Request Body
The request accepts the following data in JSON format.
** [CatalogId](#API_GrantPermissions_RequestSyntax) **
The identifier for the Data Catalog. By default, the account ID. The Data Catalog is the persistent metadata store. It contains database definitions, table definitions, and other control information to manage your AWS Lake Formation environment.
Type: String
Length Constraints: Minimum length of 1. Maximum length of 255.
Pattern: `[\u0020-\uD7FF\uE000-\uFFFD\uD800\uDC00-\uDBFF\uDFFF\t]*`
Required: No
** [Condition](#API_GrantPermissions_RequestSyntax) **
A Lake Formation condition, which applies to permissions and opt-ins that contain an expression.
Type: [Condition](API_Condition.md) object
Required: No
** [Permissions](#API_GrantPermissions_RequestSyntax) **
The permissions granted to the principal on the resource. AWS Lake Formation defines privileges to grant and revoke access to metadata in the Data Catalog and data organized in underlying data storage such as Amazon S3. Lake Formation requires that each principal be authorized to perform a specific task on Lake Formation resources.
Type: Array of strings
Valid Values: `ALL | SELECT | ALTER | DROP | DELETE | INSERT | DESCRIBE | CREATE_DATABASE | CREATE_TABLE | DATA_LOCATION_ACCESS | CREATE_LF_TAG | ASSOCIATE | GRANT_WITH_LF_TAG_EXPRESSION | CREATE_LF_TAG_EXPRESSION | CREATE_CATALOG | SUPER_USER`
Required: Yes
** [PermissionsWithGrantOption](#API_GrantPermissions_RequestSyntax) **
Indicates a list of the granted permissions that the principal may pass to other users. These permissions may only be a subset of the permissions granted in the `Privileges`.
Type: Array of strings
Valid Values: `ALL | SELECT | ALTER | DROP | DELETE | INSERT | DESCRIBE | CREATE_DATABASE | CREATE_TABLE | DATA_LOCATION_ACCESS | CREATE_LF_TAG | ASSOCIATE | GRANT_WITH_LF_TAG_EXPRESSION | CREATE_LF_TAG_EXPRESSION | CREATE_CATALOG | SUPER_USER`
Required: No
** [Principal](#API_GrantPermissions_RequestSyntax) **
The principal to be granted the permissions on the resource. Supported principals are IAM users or IAM roles, and they are defined by their principal type and their ARN.
Note that if you define a resource with a particular ARN, then later delete, and recreate a resource with that same ARN, the resource maintains the permissions already granted.
Type: [DataLakePrincipal](API_DataLakePrincipal.md) object
Required: Yes
** [Resource](#API_GrantPermissions_RequestSyntax) **
The resource to which permissions are to be granted. Resources in AWS Lake Formation are the Data Catalog, databases, and tables.
Type: [Resource](API_Resource.md) object
Required: Yes
