Securely Allowing User Testing in AWS API Gateway With IAM Policy
API Gateway is a fully managed service that makes it easy for developers to create, publish, and manage APIs. One of the key features of API Gateway is its testing capability, which allows developers to test their APIs before deploying them to production. However, in some cases, you may want to limit the permissions of the user running the tests to prevent accidental changes to the resources.
In this blog post, we will discuss how to create an IAM policy to allow a user to run tests in API Gateway without making changes to the resources.
Creating an IAM Policy
An IAM policy is a JSON document that defines the permissions for an IAM user or role. To allow a user to run tests in API Gateway without making changes to the resources, you need to create an IAM policy with the execute-api:Invoke action and specify the endpoint that the user is allowed to access.
Here's an example IAM policy:
1{
2 "Version": "2012-10-17",
3 "Statement": [
4 {
5 "Sid": "AllowTestInvocations",
6 "Effect": "Allow",
7 "Action": [
8 "execute-api:Invoke"
9 ],
10 "Resource": [
11 "arn:aws:execute-api:<REGION>:<ACCOUNT_ID>:<API_ID>/*/GET/test-path"
12 ]
13 }
14 ]
15}
In this example, the "Resource" field specifies the API endpoint that the user is allowed to access. The user is allowed to make GET requests to the "/test-path" endpoint. Replace
Note : This policy only grants access to run tests, it does not grant permission to make changes to the API Gateway resources.
Conclusion
In this blog post, we discussed how to create an IAM policy to allow a user to run tests in API Gateway without making changes to the resources. By using IAM policies, you can control the permissions of your users and prevent accidental changes to your resources.
