Note that the OIDC token can be a Bearer scheme. From my interpretation of the custom-roles.json's behavior, it looks like it appends the values in the adminRoleNames into the GraphQL vtl auth resolvers' $authRoles. TypeName.FieldName. 4 @Pickleboyonline In my case, the lambda's ARN is different than the execution role's ARN and name. Thanks for letting us know this page needs work. How to implement user authorization & fine grained access control in a GraphQL app using AWS AppSync with Amazon Cognito & AWS Amplify. The text was updated successfully, but these errors were encountered: Hi @ChristopheBougere, try this @auth rule addition on your types: If you want to also use an API Key along with IAM and Cognito, use this: Notice I added new rules, and modified your original owner and groups rules. AMAZON_COGNITO_USER_POOLS authorized. Sign up for a free GitHub account to open an issue and contact its maintainers and the community. can mark a field using the @aws_api_key directive (for example, For Region, choose the same Region as your function. name: String! First, go to the AWS AppSync console by visiting https://console.aws.amazon.com/appsync/home and clicking on Create API, then choose Build from scratch & give the API a name. Now lets take a closer look at what happens when using the AWS_LAMBDA authorization mode in AppSync. Today we are announcing a new authorization mode (AWS_LAMBDA) for AppSync leveraging AWS Lambda serverless functions. 3. For example, suppose you have the following schema and you want to restrict access to Multiple AWS AppSync APIs can share a single authentication Lambda function. I would expect that Amplify would build the project according to the CLI's parameters such as the checked out environment before runninf amplify push, but this not the case currently. If the optional regular expression (regex) to allow or block requests has been provided, AppSync evaluates it against the. restrict the readers so that they cannot add new entries, then your schema should look like Please refer to your browser's Help pages for instructions. The total size of this JSON object must not exceed 5MB. If you just omit the operations field, it will use the default, which is all values (operations: [ create, update, delete, read ]). There are other parameters such as Region that must be configured but will I just spent several hours battling this same issue. We are facing the same issue with owner based access and group based access aswell. This authorization type enforces the AWSsignature object, which came from the application. Extra notes: 5. reference Attach the following policy to the Lambda function being used: If you want the policy of the function to be locked to a single the API ID and the authentication token. email: String Note that we use two different formats to specify the denied fields, both are valid. Newbies like me: Keep in mind the role name was the short one like "trigger-lambda-role-oyzdg7k3", not the full ARN. Select the region for your Lambda function. for DynamoDB. From the schema editor in the AWS AppSync console, on the right side choose Attach Resolver for Query.getPicturesByOwner (id: ID! The supported request types are queries (for getting data from the API), mutations(for changing data via the API), and subscriptions(long-lived connections for streaming data from the API). (the lambda's ARN follows the pattern {LAMBDA-NAME}-{ENV} whereas the lambda execution role follows the pattern {Amplify-App-Name}LambdaRoleXXXXX-{ENV}. Mary does not have permissions to pass the fb: String Create a new API mapping for your custom domain name that invokes a REST API for testing only. I'd hate for us to be blocked from migrating by this. As expected, we can retrieve the list of events, but access to comments about an Event is not authorized. An output will be returned in the CLI. template When using private, you give some permissions to everyone with a valid JWT token from the configured Cognito User Pool. A client initiates a request to AppSync and attaches an Authorization header to the request. If you're using amplify Authorization module you're probably relaying in aws_cognito_user_pools . You can do this Each item is either a fully qualified field ARN in the form of Was any update made to this recently? Have a question about this project? Perhaps that's why it worked for you. this, you must have permissions to pass the role to the service. After changing the schema, go to the CLI, and write amplify update auth follow this image: Thanks for contributing an answer to Stack Overflow! access Thanks @sundersc I appreciate that. to this: GraphQL query via curl as follows: Lambda functions are called before each query or mutation, but their return value is is available only at the time you create it. The tools that we will be using to accomplish this are the AWS Amplify CLI to create the authentication service & the AWS Amplify JavaScript Client for client authentication as well as for the GraphQL client. I'm in the process of migrating our existing Amplify GraphQL API (AppSync) over to use the GraphQL Transformer v2 however I'm running into an unexpected change in IAM authorization rules that do not appear to be related (or at least adequately explained) by the new general deny-by-default authorization change. As documented here, adding the roles (arn:aws:sts::XXX:assumed-role/appsync-user-created-handler-dan-us-west-2-lambdaRole/appsync-user-created-handler in your case) to custom-roles.json file (then amplify push) should give the necessary access. Navigate to amplify/backend/api//custom-roles.json. At this point you just need to add to the codebuild config the ENVIRONMENT env variable to configure the current deployment env target and use the main cloudformation file in the build folder as codebuild output (build/cloudformation-template.json). . If you lose your secret access key, you must add new access keys to your IAM user. The @auth directive allows the override of the default provider for a given authorization mode. You specify which authorization type you use by specifying one of the following [] It expects to retrieve an RFC5785 user that created a post to edit it. If you have a model which is not "public" (available to anyone with the API key) then you need to use the correct mode to authorize the requests. AWS AppSync to call your Lambda function. may inadvertently hide fields. The trust The following example describes a Lambda function that demonstrates the various schema to control which groups can invoke which resolvers on a field, thereby giving more Connect and share knowledge within a single location that is structured and easy to search. concept applies on the condition statement block. In this post, well look at how to only allow authorized users to access data in a GraphQL API. Help me understand the context behind the "It's okay to be white" question in a recent Rasmussen Poll, and what if anything might these results show? would be for the user to gain credentials in their application, using Amazon Cognito User Please refer to your browser's Help pages for instructions. Here is an example of what I'm referring to but this is for lambdas within the same amplify project. This is because these models now perform a check to ensure that either. If you've got a moment, please tell us what we did right so we can do more of it. Well also show how to properly identify the currently authenticated user in a secure way in AWS AppSync, storing their username in the database as their unique identifier when they create resources. To change the API Authorization default mode you need to go to the data modeling tool of aws amplify and from there (below the title) there's the link to "Manage API authorization mode & keys". I got more success with a monkey patch. The Lambda function executes its authorization business logic and returns a payload to AppSync: The isAuthorized field determines if the request should be authorized or not. own, Providing access to AWS accounts owned by third parties, Providing access to externally authenticated users (identity federation), How IAM roles differ from resource-based policies. Please open a new issue for related bugs. This privileged user should not be given to anyone who is not authorized to use it and should also not be used for day-to-day operations. The preceding information demonstrates how to restrict or grant access to certain Information. However on v2, we're seeing: I don't believe this is explained by the new deny-by-default change, and I verified this by also explicitly listing the operations: What I am seeing is the generated Mutation.updateUser.auth.1.res.vtl has additional authentication logic that isn't present in the v1 transformer, and I'm trying to identify what the expected change should be, and hopefully get the documentation updated to help others. AppSync supports multiple authorization modes to cater to different access use cases: This will use the "AuthRole" IAM Role. DynamoDB allows you to perform Query operations directly on an index. (Create the custom-roles.json file if it doesn't exist). I was receiving this error "Not Authorized to access getSomeObject on type Query", I resolved by adding the group of the user making query. Our GraphQL API uses Cognito User Pools as the default authentication mechanism, and is used on the frontend by customers who log into their account. Change the API-Level authorization to mapping template will then substitute a value from the credentials (like the username)in a a Trust Policy needs to be added in order for AWS AppSync to assume the role. This was really helpful. type Farmer Can you please also tell how is owner different from private ? Just wanted to point out that the suggestion by @sundersc worked for me and give some more information on how to resolve this. built in sample template from the IAM console to create a role outside of the AWS AppSync For example, in React you can use the following code: The AWS_LAMBDA authorization mode adds a new way for developers to enforce security requirements for their AppSync APIs. }. The correct way to solve this would be to update the default authorization mode in Amplify Studio (more details in my alternative answer) I also agree that aws documentation is really unclear, 'Unauthorized' error when using AWS amplify with grahql to create a new user, The open-source game engine youve been waiting for: Godot (Ep. expression. AWS AppSync's API, do the following: To create a new Lambda authorization token, add random suffixes and/or prefixes Let say that you have a @model Post, you might want to give everyone the read permission but to give write permission only to the owner (usually the user that created the Post, but this can be configured). We are getting Unauthorized in the mutation - "Not Authorized to access updateFarmer on type Mutation" Since moving to the v2 Transformer we're now seeing our Lambdas which use IAM to access the AppSync API fail with: It appears unrelated to the documented deny-by-default change. group in the IAM User Guide. We would rather not use the heavy-weight aws-appsync package, but the DX of using it is much simpler, as the above just works because the credentials field is populated on the AWS.config automatically by AWS when invoking the Lambda. contain JSON fields of kty and kid. In the sample above iam is specified as the provider which allows you to use an UnAuthenticated Role from Cognito Identity Pools for public access, instead of an API Key. "No current user": Isn't it even possible to make unauth calls to AWS AppSync through Amplify with authentication type AMAZON_COGNITO_USER_POOLS? AMAZON_COGNITO_USER_POOLS). Create a GraphQL API object by running the update-graphql-api command. Go to AWS AppSync in the console. Directives work at the field level so you The number of seconds that the response should be cached for. I've provided the role's name in the custom-roles.json file. If you have to compile troposphere files to cloudformation add the step to do so in the buildspec. If you want to use the OIDC token as the Lambda authorization token when the getAllPosts in this example). However, it appears that $authRoles uses a lambda's ARN/name, not its execution role's ARN like you have described. Since it uses a contains check on the admin role, and each assigned role should start with the prefix you suggest. you can use mapping templates in your resolvers. One way to control throttling The text was updated successfully, but these errors were encountered: We were able to reproduce this using amplify-cli@4.24.3, with queries from both react native and plain HTTP requests. reference, Resolver @DanieleMoschiniMac Do you see the issue even after adding the IAM role to adminRoleNames on custom-roles.json file as mentioned here? It falls under HIPAA compliance and it's paramount that we do not allow unauthorized access to user data. 7 comments ChristopheBougere commented on Dec 4, 2019 aws-amplify/amplify-js#6975 Logging AWS AppSync API calls with AWS CloudTrail, I am not authorized to perform an action in Set the adminRoleNames in custom-roles.json as shown below.

AWS Lambda. Is there a compelling reason why this IAM authorization change was made as part of the v2 transformer, and any reason why it couldn't be optional? validate for only the first three client ids you would place 1F4G9H|1J6L4B|6GS5MG in the client ID Already on GitHub? billing: Shipping Is it ethical to cite a paper without fully understanding the math/methods, if the math is not relevant to why I am citing it? To prevent this from happening, you can perform the access check on the response against. This issue is that the v2 Transformer now adds additional role-based checks unrelated to the operations listed when IAM is used as the authentication mechanism. @przemekblasiak and @DivonC, is your lambda's ARN similar to its execution role's ARN? Expected behavior Looking for a help forum? After the error is identified and resolved, reroute the API mapping for your custom domain name back to your HTTP API. object only supports key-value pairs. A Lambda function must not return more than 5MB of contextual data for By default, this caching time is 300 seconds (5 Now, you should be able to visit the console and view the new service. Thanks for letting us know we're doing a good job! It also means our IaC Serverless definitions can't provide individually tailored IAM policies per lambda, like we currently can. GraphQL gives you the power to enforce different authorization controls for use cases like: One of the most compelling things about AWS AppSync is its powerful built-in user authorization features that allow all of these GraphQL user authorization use cases to be handled out of the box. this action, using context passed through for user identity validation.

We've had this architecture for over a year and has worked well, but we ran into this issue described in this ticket when we tried to migrate to the v2 Transformer. More information about @owner directive here. We also have a secondary IAM authentication mechanism which is used by backend lambdas and is secured through IAM permissions directly assigned to the Lambdas. Next, well download the AWS AppSync configuration from our AWS AppSync Dashboard under the Integrate with your app section in the getting started screen, saving it as AppSync.js in our root folder. This issue has been automatically locked since there hasn't been any recent activity after it was closed. privacy statement. So the above explains why the generated v2 auth Pipeline Resolver is returning unauthorized but I can't find anything to explain why this behaviour has changed from v1, and what the expected change on our end should be for it to work.
