Overview
An API client for Amazon Cognito Identity. To construct a client, you need to configure a :region
and :credentials
.
cognitoidentity = Aws::CognitoIdentity::Client.new(
region: region_name,
credentials: credentials,
# ...
)
See #initialize for a full list of supported configuration options.
Region
You can configure a default region in the following locations:
ENV['AWS_REGION']
Aws.config[:region]
Go here for a list of supported regions.
Credentials
Default credentials are loaded automatically from the following locations:
ENV['AWS_ACCESS_KEY_ID']
andENV['AWS_SECRET_ACCESS_KEY']
Aws.config[:credentials]
- The shared credentials ini file at
~/.aws/credentials
(more information) - From an instance profile when running on EC2
You can also construct a credentials object from one of the following classes:
Alternatively, you configure credentials with :access_key_id
and
:secret_access_key
:
# load credentials from disk
creds = YAML.load(File.read('/path/to/secrets'))
Aws::CognitoIdentity::Client.new(
access_key_id: creds['access_key_id'],
secret_access_key: creds['secret_access_key']
)
Always load your credentials from outside your application. Avoid configuring credentials statically and never commit them to source control.

#delete_identities(options = {}) ⇒ Types::DeleteIdentitiesResponse
Deletes identities from an identity pool. You can specify a list of 1-60 identities that you want to delete.
You must use AWS Developer credentials to call this API.
#delete_identity_pool(options = {}) ⇒ Struct
Deletes an identity pool. Once a pool is deleted, users will not be able to authenticate with the pool.
You must use AWS Developer credentials to call this API.
#describe_identity(options = {}) ⇒ Types::IdentityDescription
Returns metadata related to the given identity, including when the identity was created and any associated linked logins.
You must use AWS Developer credentials to call this API.
#describe_identity_pool(options = {}) ⇒ Types::IdentityPool
Gets details about a particular identity pool, including the pool name, ID description, creation date, and current number of users.
You must use AWS Developer credentials to call this API.
#get_credentials_for_identity(options = {}) ⇒ Types::GetCredentialsForIdentityResponse
Returns credentials for the provided identity ID. Any provided logins will be validated against supported login providers. If the token is for cognito-identity.amazonaws.com, it will be passed through to AWS Security Token Service with the appropriate role for the token.
This is a public API. You do not need any credentials to call this API.
#get_id(options = {}) ⇒ Types::GetIdResponse
Generates (or retrieves) a Cognito ID. Supplying multiple logins will create an implicit linked account.
This is a public API. You do not need any credentials to call this API.
#get_identity_pool_roles(options = {}) ⇒ Types::GetIdentityPoolRolesResponse
Gets the roles for an identity pool.
You must use AWS Developer credentials to call this API.
#get_open_id_token(options = {}) ⇒ Types::GetOpenIdTokenResponse
Gets an OpenID token, using a known Cognito ID. This known Cognito ID is returned by GetId. You can optionally add additional logins for the identity. Supplying multiple logins creates an implicit link.
The OpenId token is valid for 10 minutes.
This is a public API. You do not need any credentials to call this API.
#get_open_id_token_for_developer_identity(options = {}) ⇒ Types::GetOpenIdTokenForDeveloperIdentityResponse
Registers (or retrieves) a Cognito IdentityId
and an OpenID Connect token for a user authenticated by your backend authentication process. Supplying multiple logins will create an implicit linked account. You can only specify one developer provider as part of the Logins
map, which is linked to the identity pool. The developer provider is the "domain" by which Cognito will refer to your users.
You can use GetOpenIdTokenForDeveloperIdentity
to create a new identity and to link new logins (that is, user credentials issued by a public provider or developer provider) to an existing identity. When you want to create a new identity, the IdentityId
should be null. When you want to associate a new login with an existing authenticated/unauthenticated identity, you can do so by providing the existing IdentityId
. This API will create the identity in the specified IdentityPoolId
.
You must use AWS Developer credentials to call this API.
#list_identities(options = {}) ⇒ Types::ListIdentitiesResponse
Lists the identities in an identity pool.
You must use AWS Developer credentials to call this API.
#list_identity_pools(options = {}) ⇒ Types::ListIdentityPoolsResponse
Lists all of the Cognito identity pools registered for your account.
You must use AWS Developer credentials to call this API.
#list_tags_for_resource(options = {}) ⇒ Types::ListTagsForResourceResponse
Lists the tags that are assigned to an Amazon Cognito identity pool.
A tag is a label that you can apply to identity pools to categorize and manage them in different ways, such as by purpose, owner, environment, or other criteria.
You can use this action up to 10 times per second, per account.
#lookup_developer_identity(options = {}) ⇒ Types::LookupDeveloperIdentityResponse
Retrieves the IdentityID
associated with a DeveloperUserIdentifier
or the list of DeveloperUserIdentifier
values associated with an IdentityId
for an existing identity. Either IdentityID
or DeveloperUserIdentifier
must not be null. If you supply only one of these values, the other value will be searched in the database and returned as a part of the response. If you supply both, DeveloperUserIdentifier
will be matched against IdentityID
. If the values are verified against the database, the response returns both values and is the same as the request. Otherwise a ResourceConflictException
is thrown.
LookupDeveloperIdentity
is intended for low-throughput control plane operations: for example, to enable customer service to locate an identity ID by username. If you are using it for higher-volume operations such as user authentication, your requests are likely to be throttled. GetOpenIdTokenForDeveloperIdentity is a better option for higher-volume operations for user authentication.
You must use AWS Developer credentials to call this API.
#merge_developer_identities(options = {}) ⇒ Types::MergeDeveloperIdentitiesResponse
Merges two users having different IdentityId
s, existing in the same identity pool, and identified by the same developer provider. You can use this action to request that discrete users be merged and identified as a single user in the Cognito environment. Cognito associates the given source user (SourceUserIdentifier
) with the IdentityId
of the DestinationUserIdentifier
. Only developer-authenticated users can be merged. If the users to be merged are associated with the same public provider, but as two different users, an exception will be thrown.
The number of linked logins is limited to 20. So, the number of linked logins for the source user, SourceUserIdentifier
, and the destination user, DestinationUserIdentifier
, together should not be larger than 20. Otherwise, an exception will be thrown.
You must use AWS Developer credentials to call this API.
#set_identity_pool_roles(options = {}) ⇒ Struct
Sets the roles for an identity pool. These roles are used when making calls to GetCredentialsForIdentity action.
You must use AWS Developer credentials to call this API.
#tag_resource(options = {}) ⇒ Struct
Assigns a set of tags to an Amazon Cognito identity pool. A tag is a label that you can use to categorize and manage identity pools in different ways, such as by purpose, owner, environment, or other criteria.
Each tag consists of a key and value, both of which you define. A key is a general category for more specific values. For example, if you have two versions of an identity pool, one for testing and another for production, you might assign an Environment
tag key to both identity pools. The value of this key might be Test
for one identity pool and Production
for the other.
Tags are useful for cost tracking and access control. You can activate your tags so that they appear on the Billing and Cost Management console, where you can track the costs associated with your identity pools. In an IAM policy, you can constrain permissions for identity pools based on specific tags or tag values.
You can use this action up to 5 times per second, per account. An identity pool can have as many as 50 tags.
#unlink_developer_identity(options = {}) ⇒ Struct
Unlinks a DeveloperUserIdentifier
from an existing identity. Unlinked developer users will be considered new identities next time they are seen. If, for a given Cognito identity, you remove all federated identities as well as the developer user identifier, the Cognito identity becomes inaccessible.
You must use AWS Developer credentials to call this API.
#unlink_identity(options = {}) ⇒ Struct
Unlinks a federated identity from an existing account. Unlinked logins will be considered new identities next time they are seen. Removing the last linked login will make this identity inaccessible.
This is a public API. You do not need any credentials to call this API.
#untag_resource(options = {}) ⇒ Struct
Removes the specified tags from an Amazon Cognito identity pool. You can use this action up to 5 times per second, per account
#update_identity_pool(options = {}) ⇒ Types::IdentityPool
Updates an identity pool.
You must use AWS Developer credentials to call this API.
#wait_until(waiter_name, params = {}) {|waiter| ... } ⇒ Boolean
Waiters polls an API operation until a resource enters a desired state.
Basic Usage
Waiters will poll until they are succesful, they fail by entering a terminal state, or until a maximum number of attempts are made.
# polls in a loop, sleeping between attempts client.waiter_until(waiter_name, params)
Configuration
You can configure the maximum number of polling attempts, and the delay (in seconds) between each polling attempt. You configure waiters by passing a block to #wait_until:
# poll for ~25 seconds
client.wait_until(...) do |w|
w.max_attempts = 5
w.delay = 5
end
Callbacks
You can be notified before each polling attempt and before each
delay. If you throw :success
or :failure
from these callbacks,
it will terminate the waiter.
started_at = Time.now
client.wait_until(...) do |w|
# disable max attempts
w.max_attempts = nil
# poll for 1 hour, instead of a number of attempts
w.before_wait do |attempts, response|
throw :failure if Time.now - started_at > 3600
end
end
Handling Errors
When a waiter is successful, it returns true
. When a waiter
fails, it raises an error. All errors raised extend from
Waiters::Errors::WaiterFailed.
begin
client.wait_until(...)
rescue Aws::Waiters::Errors::WaiterFailed
# resource did not enter the desired state in time
end
#waiter_names ⇒ Array<Symbol>
Returns the list of supported waiters. The following table lists the supported waiters and the client method they call:
Waiter Name | Client Method | Default Delay: | Default Max Attempts: |
---|
