Control access to an API with IAM permissions
You control access to your Amazon API Gateway API with IAM permissions by controlling access to the following two API Gateway component processes:
To create, deploy, and manage an API in API Gateway, you must grant the API developer permissions to perform the required actions supported by the API management component of API Gateway.
To call a deployed API or to refresh the API caching, you must grant the API caller permissions to perform required IAM actions supported by the API execution component of API Gateway.
The access control for the two processes involves different permissions models, explained next.
API Gateway permissions model for creating and managing an API
To allow an API developer to create and manage an API in API Gateway, you must create IAM permissions policies that allow a specified API developer to create, update, deploy, view, or delete required API entities. You attach the permissions policy to an IAM user representing the developer, to an IAM group containing the user, or to an IAM role assumed by the user.
For more information on how to use this permissions model, see API Gateway identity-based policies.
API Gateway permissions model for invoking an API
To allow an API caller to invoke the API or refresh its caching, you must create IAM policies that permit a specified API caller to invoke the API method for which the IAM user authentication is enabled. The API developer sets the method's property to to require that the caller submit the IAM user's access keys to be authenticated. Then, you attach the policy to an IAM user representing the API caller, to an IAM group containing the user, or to an IAM role assumed by the user.
In this IAM permissions policy statement, the IAM element contains a list of deployed API methods identified by given HTTP verbs and API Gateway resource paths. The IAM element contains the required API Gateway API executing actions. These actions include or , where designates the underlying API execution component of API Gateway.
For more information on how to use this permissions model, see Control access for invoking an API.
When an API is integrated with an AWS service (for example, AWS Lambda) in the back end, API Gateway must also have permissions to access integrated AWS resources (for example, invoking a Lambda function) on behalf of the API caller. To grant these permissions, create an IAM role of the AWS service for API Gateway type. When you create this role in the IAM Management console, this resulting role contains the following IAM trust policy that declares API Gateway as a trusted entity permitted to assume the role:
If you create the IAM role by calling the create-role command of CLI or a corresponding SDK method, you must supply the above trust policy as the input parameter of . Do not attempt to create such a policy directly in the IAM Management console or calling AWS CLI create-policy command or a corresponding SDK method.
For API Gateway to call the integrated AWS service, you must also attach to this role appropriate IAM permissions policies for calling integrated AWS services. For example, to call a Lambda function, you must include the following IAM permissions policy in the IAM role:
Note that Lambda supports resource-based access policy, which combines both trust and permissions policies. When integrating an API with a Lambda function using the API Gateway console, you are not asked to set this IAM role explicitly, because the console sets the resource-based permissions on the Lambda function for you, with your consent.
To enact access control to an AWS service, you can use either the caller-based permissions model, where a permissions policy is directly attached to the caller's IAM user or group, or the role-based permission model, where a permissions policy is attached to an IAM role that API Gateway can assume. The permissions policies may differ in the two models. For example, the caller-based policy blocks the access while the role-based policy allows it. You can take advantage of this to require that an IAM user access an AWS service through an API Gateway API only.

Create Policies to Control Access to Network and API Gateway-Related Resources
When API Gateway users define a new API gateway and new API deployments, they have to specify a compartment for those API Gateway-related resources. Users can only specify a compartment that the groups to which they belong have been granted access. To enable users to specify a compartment, you must create an identity policy to grant the groups access.
To create a policy to give users access to API Gateway-related resources in the compartment that will own those resources:
- Log in to the Console as a tenancy administrator.
- In the Console, open the navigation menu and click Identity & Security. Under Identity, click Policies. A list of the policies in the compartment you're viewing is displayed.
- Select the compartment that will own API Gateway-related resources from the list on the left.
- Click Create Policy.
Enter the following:
- Name: A meaningful name for the policy (for example, ). The name must be unique across all policies in your tenancy. You cannot change this later. Avoid entering confidential information.
- Description: A meaningful description (for example, ). You can change this later if you want to.
Statement: The following policy statement to give the group access to all API Gateway-related resources in the compartment:
As Statement 1:, enter the following policy statement to give the group access to all API Gateway-related resources in the compartment:
- Tags: If you have permissions to create a resource, then you also have permissions to apply free-form tags to that resource. To apply a defined tag, you must have permissions to use the tag namespace. For more information about tagging, see Resource Tags. If you are not sure whether to apply tags, skip this option (you can apply tags later) or ask your administrator.
- Click Create to create the policy giving API Gateway users access to API Gateway-related resources in the compartment.
Normally, API gateways and API deployments are created in the same compartment. However, in large development teams with many API developers, you might find it useful to create separate compartments for API gateways and for API deployments. Doing so will enable you to give different groups of users appropriate access to those resources.

IAM policy examples for API execution permissions
For permissions model and other background information, see Control access for invoking an API.
The following policy statement gives the user permission to call any POST method along the path of , in the stage of , for the API with the identifier of , assuming the corresponding API has been deployed to the AWS region of us-east-1:
The following example policy statement gives the user permission to call any method on the resource path of , in any stage, for the API with the identifier of , in any AWS region where the corresponding API has been deployed:
I am trying to invoke a lambda function from an API Gateway. I have followed the next tutorial: https://docs.aws.amazon.com/apigateway/latest/developerguide/integrating-api-with-aws-services-lambda.html
However, I get the following error when I test it from the web of API Gateway:
I have search in google and I have not been able to solve it (this, for instance).
If I go to the IAM Management Console, I can see that the trust relationship allows API Gateway to assume the rol, and the JSON of the trust relationship is the following:
I have tried also with:
The policy of the role is the next:

Gateway permissions api
here is my problem: I have different users that can access an API using IAM authentication. Every user send some data, that have to be put in a kinesis stream. Every user has its own kinesis stream. The gateway put the data on the correct stream based on a "streamName" field present in the request. The stream consumers discard every data eventually put in the wrong stream (for instance in the case "user A" has specified "stream B").
This system is working fine, but it is not efficient.
I would like to enforce the right utilization of the streams to the api gateway level using IAM roles/policies. If every user has a policy that grant him the access only to its kinesis stream, is there a way to configure the system to have the bad requests rejected without the put to the streams are performed?
In other words, I would like to have the API gateway to be granted the access to a particular kinesis stream based on the policy of the caller user.
Thank you for your help. Gabriele
I think I found an hint for the solution. Here: https://docs.aws.amazon.com/apigateway/latest/developerguide/permissions.html
In the light blue box at the and it states: To enact access control to an AWS service, you can use either the caller-based permissions model, where a permissions policy is directly attached to the caller's IAM user or group, or the role-based permission model, where a permissions policy is attached to an IAM role that API Gateway can assume.
I think that the "caller-based permission model" could be the right way to do it.
Configure Permissions for API Gateway Logging to CloudWatch
Instructions for enabling account level logging from API Gateway to CloudWatch.
This is a one time operation that must be performed on each AWS account to allow API Gateway to push logs to CloudWatch.
Create a policy document
The managed policy, with an ARN of , has all the required permissions to enable API Gateway logging to CloudWatch. To grant these permissions to your account, first create an IAM role with as its trusted entity.
Save this snippet as
Create an account role to act as ApiGateway and write to CloudWatchLogs
NASA users in NGAP: be sure to use your account's permission boundary.
Note the Arn of the returned role for the last step.
Attatch correct permissions to role.
Next attach the policy to the IAM role.
Update Account Api Gateway settings with correct permissions.
Finally, set the IAM role ARN on the property on your API Gateway Account settings.
