Cognito token endpoint
Amazon Cognito scales to millions of users and supports sign-in with social identity providers, such as Facebook, Google, and Amazon, and enterprise identity providers via SAML 2.
After successful authentication, Amazon Cognito returns user pool tokens to your app. You can use the tokens to grant your users access to your own server-side resources, or to the Amazon API Gateway. This Lambda trigger allows you to customize an identity token before it is generated. You can use this trigger to add new claims, update claims, or suppress claims in the identity token. A user pool is a user directory in Amazon Cognito.
With a user pool, your users can sign in to your web or mobile app through Amazon Cognito. Note down the User Pool Id. An App Client is a way to grant applications access to authenticate against a user pool and to generate ID and Access Tokens appropriately for end users.
Note down the App Client id and App client secret. The below example lambda function uses Python 3. This allows Cognito the access to assume the Lambda Role so that it can invoke the Pre Token generator. The below steps detail how to use Authorization Code grant method for authorizing end users. This code is then sent to a custom application that can exchange it for the desired tokens. Provide the test-user username, password created above and sign in. AppSync uses security Read more….

The user pool client typically makes this request through a browser. Web browsers include Chrome or Firefox. Android browsers include Custom Chrome Tab. For more information on the specification see Authorization Endpoint. The response type. Must be code or token. Indicates whether the client wants an authorization code authorization code grant flow for the end user or directly issues tokens for end user implicit flow.
Must be a pre-registered client in the user pool and must be enabled for federation. The URL to which the authentication server redirects the browser after authorization has been granted by the user.
See OAuth 2. An opaque value the clients adds to the initial request. The authorization server includes this value when redirecting back to the client. This value must be used by the client to prevent CSRF attacks. Used by the developer to directly authenticate with a specific provider. For other identity providers this would be the name you assigned to the IdP in your user pool. Used by the developer to map to a provider name without exposing the provider name.
Can be a combination of any system-reserved scopes or custom scopes associated with a client.
Scopes must be separated by spaces. System reserved scopes are openidemailphoneprofileand aws.
Server to Server Auth with Amazon Cognito
Any scope used must be preassociated with the client or it will be ignored at runtime. If the client doesn't request any scopes, the authentication server uses all scopes associated with the client. An ID token is only returned if openid scope is requested. The access token can be only used against Amazon Cognito User Pools if aws. The phoneemailand profile scopes can only be requested if openid scope is also requested.When an OAuth 2.
The OAuth 2. In some cases, especially with small services, both endpoints are part of the same system, and can share token information internally such as in a database. In larger systems where the two endpoints are on different servers, this has led to proprietary and non-standard protocols for communicating between the two servers. The token introspection endpoint needs to be able to return information about a token, so you will most likely build it in the same place that the token endpoint lives.
The two endpoints need to either share a database, or if you have implemented self-encoded tokens, they will need to share the secret. It is expected that this endpoint is not made publicly available to developers. End-user clients should not be allowed to use this endpoint since the response may contain privileged information that developers should not have access to. One way to protect the endpoint is to put it on an internal server that is not accessible from the outside world, or it could be protected with HTTP basic auth.
Some of the properties in the Introspection spec are specifically for JWT tokens, so we will only cover the basic ones here. You can also add additional properties in the response if you have additional information about a token that may be useful. This is a boolean value of whether or not the presented token is currently active. The unix timestamp integer timestamp, number of seconds since January 1, UTC indicating when this token will expire. If the introspection endpoint is publicly accessible, the endpoint must first validate the authentication.
In any of these cases, it is not considered an error response, and the endpoint returns simply an inactive flag.
Using a token introspection endpoint means that any resource server will be relying on the endpoint to determine whether an access token is currently active or not.
This means the introspection endpoint is solely responsible for deciding whether API requests will succeed. If the introspection endpoint is left open and un-throttled, it presents a means for an attacker to poll the endpoint fishing for a valid token.
To prevent this, the server must either require authentication of the clients using the endpoint, or only make the endpoint available to internal servers through other means such as a firewall.
Note that the resources servers are also a potential target of a fishing attack, and should take countermeasures such as rate limiting to prevent this. Consumers of the introspection endpoint may wish to cache the response of the endpoint for performance reasons. As such, it is important to consider the performance and security trade-offs when deciding to cache the values. For example, shorter cache expiration times will result in higher security since the resource servers will have to query the introspection endpoint more frequently, but will result in an increased load on the endpoint.
Longer expiration times leave a window open where a token may actually be expired or revoked, but still be able to be used at a resource server for the remaining duration of the cache time. The introspection endpoint does not necessarily need to return the same information for all queries of the same token.
For example, two different resource servers if they authenticate themselves when making the introspection request may get different views of the state of the token. This can be used to limit the information about the token that is returned to a particular resource server.
This makes it possible to have tokens that can be used at multiple resource servers without other servers ever knowing it is possible to be used at any other server. Introspection Endpoint The token introspection endpoint needs to be able to return information about a token, so you will most likely build it in the same place that the token endpoint lives.
Example Response Below is an example of the response that the introspection endpoint would return. The token requested does not exist or is invalid The token expired The token was issued to a different client than is making this request In any of these cases, it is not considered an error response, and the endpoint returns simply an inactive flag.
Token Fishing If the introspection endpoint is left open and un-throttled, it presents a means for an attacker to poll the endpoint fishing for a valid token. Caching Consumers of the introspection endpoint may wish to cache the response of the endpoint for performance reasons. Limiting Information The introspection endpoint does not necessarily need to return the same information for all queries of the same token.

With an architecture like this, it seems logical that my apps e. So far so good, as I should have what I need. But when I paste in the Access Token, I get - unauthorized. In my Cognito setup, I have enabled Authorization Code Grant flow only, with email and openid scopes this seems to be the minimum allowed by Cognito as I get an error trying to save without at least these ticked.
If so, where are these configured? Or am I missing something? You can use an access token with the same authorizer that works for the id token, but there is some additional setup to be done in the User Pool and the APIG. Even when this extra setup is done you cannot use the built-in authorizer test functionality with an access token, only an id token.
