# Actions for Amazon Cognito Identity using AWS SDKs
The following code examples demonstrate how to perform individual Amazon Cognito Identity actions with AWS SDKs. Each example includes a link to GitHub, where you can find instructions for setting up and running the code.
These excerpts call the Amazon Cognito Identity API and are code excerpts from larger programs that must be run in context. You can see actions in context in [Scenarios for Amazon Cognito Identity using AWS SDKs](cognito-identity_code_examples_scenarios.md).
The following examples include only the most commonly used actions. For a complete list, see the [Amazon Cognito Identity API Reference](https://docs.aws.amazon.com/cognitoidentity/latest/APIReference/Welcome.html).

# Use `CreateIdentityPool` with an AWS SDK or CLI
The following code examples show how to use `CreateIdentityPool`.
------
#### [ CLI ]
**AWS CLI**
**To create an identity pool with Cognito identity pool provider**
This example creates an identity pool named MyIdentityPool. It has a Cognito identity pool provider. Unauthenticated identities are not allowed.
Command:
```
aws cognito-identity create-identity-pool --identity-pool-name MyIdentityPool --no-allow-unauthenticated-identities --cognito-identity-providers ProviderName="cognito-idp.us-west-2.amazonaws.com/us-west-2_aaaaaaaaa",ClientId="3n4b5urk1ft4fl3mg5e62d9ado",ServerSideTokenCheck=false
```
Output:
```
{
"IdentityPoolId": "us-west-2:11111111-1111-1111-1111-111111111111",
"IdentityPoolName": "MyIdentityPool",
"AllowUnauthenticatedIdentities": false,
"CognitoIdentityProviders": [
{

# Use `SetIdentityPoolRoles` with a CLI
The following code examples show how to use `SetIdentityPoolRoles`.
------
#### [ CLI ]
**AWS CLI**
**To set identity pool roles**
The following `set-identity-pool-roles` example sets an identity pool role.
```
aws cognito-identity set-identity-pool-roles \
--identity-pool-id "us-west-2:11111111-1111-1111-1111-111111111111" \
--roles authenticated="arn:aws:iam::111111111111:role/Cognito_MyIdentityPoolAuth_Role"
```
+ For API details, see [SetIdentityPoolRoles](https://awscli.amazonaws.com/v2/documentation/api/latest/reference/cognito-identity/set-identity-pool-roles.html) in *AWS CLI Command Reference*.
------
#### [ PowerShell ]
**Tools for PowerShell V4**
**Example 1: Configures the specific Identity Pool to have an unauthenticated IAM role.**
```
Set-CGIIdentityPoolRole -IdentityPoolId us-east-1:0de2af35-2988-4d0b-b22d-EXAMPLEGUID1 -Role @{ "unauthenticated" = "arn:aws:iam::123456789012:role/CommonTests1Role" }
```

**Tools for PowerShell V5**
**Example 1: Configures the specific Identity Pool to have an unauthenticated IAM role.**
```
Set-CGIIdentityPoolRole -IdentityPoolId us-east-1:0de2af35-2988-4d0b-b22d-EXAMPLEGUID1 -Role @{ "unauthenticated" = "arn:aws:iam::123456789012:role/CommonTests1Role" }

# Use `UpdateIdentityPool` with a CLI
The following code examples show how to use `UpdateIdentityPool`.
------
#### [ CLI ]
**AWS CLI**
**To update an identity pool**
This example updates an identity pool. It sets the name to MyIdentityPool. It adds Cognito as an identity provider. It disallows unauthenticated identities.
Command:
```
aws cognito-identity update-identity-pool --identity-pool-id "us-west-2:11111111-1111-1111-1111-111111111111" --identity-pool-name "MyIdentityPool" --no-allow-unauthenticated-identities --cognito-identity-providers ProviderName="cognito-idp.us-west-2.amazonaws.com/us-west-2_111111111",ClientId="3n4b5urk1ft4fl3mg5e62d9ado",ServerSideTokenCheck=false
```
Output:
```
{
"IdentityPoolId": "us-west-2:11111111-1111-1111-1111-111111111111",
"IdentityPoolName": "MyIdentityPool",
"AllowUnauthenticatedIdentities": false,
"CognitoIdentityProviders": [
{
"ProviderName": "cognito-idp.us-west-2.amazonaws.com/us-west-2_111111111",
"ClientId": "3n4b5urk1ft4fl3mg5e62d9ado",
"ServerSideTokenCheck": false
}
]
}
```

#### [ PowerShell ]
**Tools for PowerShell V4**
**Example 1: Updates some of the Identity Pool properties, in this case the name of the Identity Pool.**
```
Update-CGIIdentityPool -IdentityPoolId us-east-1:0de2af35-2988-4d0b-b22d-EXAMPLEGUID1 -IdentityPoolName NewPoolName
```
**Output:**
```
