The function also provides some data in the resolverContext object. My schema.graphql looks like this (with other types and fields, but shouldn't impact our case): I tried a bunch of workarounds but nothing worked. The JWT is sent in the authorization header & is available in the resolver. The function overrides the default TTL for the response, and sets it to 10 seconds. As a user, we log in to the application and receive an identity token. authorized. authorization token is of the correct format before your function is called. When building a real world app there are many important and complex things that need to be taken into consideration, one of the most important being a real world scalable & easy to implement user authorization story. using a token which does not match this regular expression will be denied automatically. Manage your access keys as securely as you do your user name and password. Navigate to the Settings page for your API. How to implement user authorization & fine grained access control in a GraphQL app using AWS AppSync with Amazon Cognito & AWS Amplify. If you want a role that has access to perform all data operations: You can find YourGraphQLApiId from the main API listing page in the AppSync I hope this helps someone else save a bit of time. A client initiates a request to AppSync and attaches an Authorization header to the request. Sign in 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). Thanks again, and I'll update this ticket in a few weeks once we've validated it. When used in conjunction with amplify add auth the CLI generates scoped down IAM policies for the UnAuthenticated role automatically. conditional statement which will then be compared to a value in your database. These users will require assistance to gain access . @model(subscriptions: { level: public }) { By doing profileImg: String returned from a resolver. For example, suppose you have the following schema and you want to restrict access to reference your SigV4 signature or OIDC token as your Lambda authorization token when certain If you are using an existing role, You can create additional user accounts to perform. However when using a @DanieleMoschiniMac Do you see the issue even after adding the IAM role to adminRoleNames on custom-roles.json file as mentioned here? Lambda expands the flexibility in AppSync APIs allowing to meet any authorization customization business requirements. In our resolver, we look for certain data, in our case the users username, to either conditionally perform operations, query based on the current user, or create mutations using the currently logged in users username. First, we want to make sure that when we create a new city, the users username gets stored in the author field. version 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). If you just omit the operations field, it will use the default, which is all values (operations: [ create, update, delete, read ]). Identify what's causing the errors by viewing your REST API's execution logs in CloudWatch. By clicking Sign up for GitHub, you agree to our terms of service and 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. you can specify an unambiguous field ARN in the form of 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. You can Access keys consist of two parts: an access key ID (for example, AKIAIOSFODNN7EXAMPLE) and a secret access key (for example, 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. Sign in to the AWS Management Console and open the AppSync contain JSON fields of kty and kid. TypeName.FieldName. There may be cases where you cannot control the response from your data source, but you the role has been added to the custom-roles.json file as described above. GraphQL query via curl as follows: Lambda functions are called before each query or mutation, but their return value is When sharing an authorization function between multiple APIs, be aware that short-form 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. To get started right away, see Creating your first IAM delegated user and This will take you to DynamoDB. authorizer: You can also include other configuration options such as the token Thanks for letting us know we're doing a good job! Lambda functions used for authorization require a principal policy for Looks like everything works well. If you've got a moment, please tell us how we can make the documentation better. In my case we have local scripts accessing the graphql API via aws access keys, adding this to custom-roles.json resolved the issue: Hi, IAM User Guide. This is specific to update mutations. You can mix and match Lambda with all the other AppSync authorization modes in a single API to enhance security and protect your GraphQL data backends and clients. (such as an index on Author).

RV coach and starter batteries connect negative to chassis; how does energy from either batteries' + terminal know which battery to flow back to? The resolverContext field is a JSON object passed as $ctx.identity.resolverContext to the AppSync resolver. AWS AppSync. fictional appsync:GetWidget permissions. @aws_cognito_user_pools - To specify that the field is Well occasionally send you account related emails. Nested keys are not supported. The Lambda function you specify will receive an event with the following shape: The authorization function must return at least isAuthorized, a boolean for unauthenticated GraphQL endpoints is through the use of API keys. I'm not sure if it's currently used when iam is set as the AuthProvider, but if not, potentially we could specify something like: Specifying that would mean this particular iamCheck() function would not be invoked by mutation resolver generators. is available only at the time you create it. Multiple Authorization methods in a single GraphQL API with AWS AppSync: Security at the Data Definition Level | by Ed Lima | Medium 500 Apologies, but something went wrong on our end.. resolver: The value of $ctx.identity.resolverContext.apple in resolver I removed, then amplify pushed, and recreated the table and it worked. AWS_IAM authorization Use the drop down to select your function ARN (alternatively, paste your function ARN directly). the token was issued (iat) and may include the time at which it was authenticated For the IAM @auth rule, here's the relevant documentation: https://aws-amplify.github.io/docs/cli-toolchain/graphql?sdk=js#private-authorization. Sign up for a free GitHub account to open an issue and contact its maintainers and the community. (auth_time). For example, if the following structure is returned by a modes are enabled for AWS AppSync's API, do the following: To create a new Lambda authorization token, add random suffixes and/or prefixes If you are already familiar with AWS AppSync & want to dive deeper on more complex user authorization examples, check out this recent post by Richard Threlkeld. Why can't I read relational data when I use iam for auth, but can read when authenticated through cognito user pools. If you want to use the AppSync console, also add your username or role name to the list as mentioned here. your provider authorizes multiple applications, you can also provide a regular expression 4 It falls under HIPAA compliance and it's paramount that we do not allow unauthorized access to user data. The appropriate principal policy will be added automatically, allowing AWS AppSync's API, do the following: To create a new Lambda authorization token, add random suffixes and/or prefixes Extra notes: When using multiple authorization modes you can use AppSync directives in your GraphQL schema to restrict access to data types and fields based on the mode used to authorize the request. Finally, customers may have private system hosted in their VPC that they can only access from a Lambda function configured with VPC access. logic, which we describe in Filtering console the permissions will not be automatically scoped down on a resource and you should { allow: private, operations: [read] } privacy statement. The flow that we will be working with looks like this: The data flow for a mutation could look something like this: In this example we can now query based on the author index. AWS AppSync API service, based on GraphQL API, requires authorization for applications to interact with it. an Identity object that has the following values: To use this object in a DynamoDBUpdateItem call, you need to store the user // The following resolves an error thrown by the underlying Apollo client: // Invariant Violation: fetch is not found globally and no fetcher passed, // eslint-disable-next-line @typescript-eslint/no-explicit-any, 'No AWS.config.credentials is available; this is required. However, nothing I did on the schema was effective (including adding @aws_cognito_user_pools as indicated). The default V2 IAM authorization rule tries to keep the api as restrictive as possible. 7 comments ChristopheBougere commented on Dec 4, 2019 aws-amplify/amplify-js#6975 This also fixed the subscriptions for me. The problem is that Apollo don't cache query because error occurred. "Public S3 buckets" - but rather it means Authorization is using an entirely different mechanism (IAM or API key) which does not and cannot have an owner, nor a group associated with the identity performing the query. controlled access to your customers. applications. mobile: AWSPhone! There are other parameters such as Region that must be configured but will authorization, Using expression. The @auth directive allows the override of the default provider for a given authorization mode. 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. Then scroll to the bottom and click Create. own in the IAM User Guide. perform this action before moving your application to production. follows: The resolver mapping template for editPost (shown in an example at the end fields. application can leverage the users and groups in your user pools and associate these with Hi @sundersc and everyone else experiencing this issue. update. You can specify authorization modes on individual fields in the schema. Unauthenticated APIs require more strict throttling than authenticated APIs. The operation is either executed or rejected as unauthorized depending on the logic declared in our resolver. You obtain this file in one of two ways, depending on whether you are creating your AppSync API in the AppSync console or using the Amplify CLI. you can use mapping templates in your resolvers. When using Lambda functions for authorization, the 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. Thanks for your time. cart: [CartItem] If you want to set access controls on the data based on certain conditions With Lambda authorization you specify a Lambda function with custom business logic that determines if requests should be authorized and resolved by AppSync. Select the region for your Lambda function. The AppSync interface allows developers to define the schema of the GraphQL API and attach resolver functions to each defined request type. And possibly an example with an outside function considering many might face the same issue as I. Thanks for contributing an answer to Stack Overflow! Find centralized, trusted content and collaborate around the technologies you use most. AppSync, Cognito. All rights reserved. original OIDC token for authentication. the API ID and the authentication token. The main difference between In this example: others cant read, update, or delete.

Choose the AWS Region and Lambda ARN to authorize API calls authorization token. This username data is available as part of the user identity token passed along with the request in an authorization header, and we can access this in our resolver as the identity in the context.identity field available in the resolver. billing: Shipping following. 1. Well occasionally send you account related emails. this, you must have permissions to pass the role to the service. You can use the new @aws_lambda AppSync directive to specify if a type of field should be authorized by the AWS_LAMBDA authorization mode when using multiple authorization modes in your GraphQL API. It seems like the Resolver is requiring all the Lambdas using IAM to assume that authRole, but I'm not sure the best way to do that. AWS AppSync. fields and object type definitions: @aws_api_key - To specify the field is API_KEY 4 Next, well update a couple of resolvers. created the post: This example uses a PutItem that overwrites all values rather than an []. API Keys are best used for public APIs (or parts of your schema which you wish to be public) or prototyping, and you must specify the expiration time before deploying. Have a question about this project? Not the answer you're looking for? For public users, it is recommended you use IAM to authenticated unauthenticated users to run queries. Thanks for reading the issue and replying @sundersc. To be able to use public the API must have API Key configured. I just want to be clear about what this ticket was created to address. this: Note that you can omit the @aws_auth directive if you want to default to a authorization In this post, well look at how to only allow authorized users to access data in a GraphQL API. The secret access key Ackermann Function without Recursion or Stack. API. Please let us know if you hit into this issue and we can re-open. I also believe that @sundersc's workaround might not accurately describe the issue at hand. You modes. This mutation is handled by a direct Lambda resolver, which uses Cognito's admin API to create the new user and set its tenant ID to the admin user's tenant ID. Your clients attach an Authorization header to AppSync requests that a Lambda function evaluates to enforce authorization according your specific business rules. Next we will add user-signin capabilities to the app with Amazon Cognito: Then push the updated config to the AWS console. If you lose your secret access key, you must add new access keys to your IAM user. execute in the shortest amount of time as possible to scale the performance of your An Issuer URL is the only required configuration value that you provide to AWS AppSync (for example, The @auth directive allows the override of the default provider for a given authorization mode. Then, use the original OIDC token for authentication. After that, $adminRoles contained the correct environment's lambda ARNs and I no longer received the "Unauthorized" error in GraphQL. Hi @danrivett - Just wanted to follow up to see whether the workaround solved the issue for your application. Next, create the following schema and click Save:. So in the end, here is my complete @auth rule: I am still doing some tests but this seems to work well . It only happened to one of our calls because it's the only one we do a get that is scoped to an owner. authorization setting. It seemed safe enough to me as we've verified other Lambdas cannot access the AppSync API, but perhaps there's other negative consequences that prevent supporting that approach? If you enjoyed this article, please clap n number of times and share it! act on the minimal set of resources necessary. I guess a good solution would be to remove manually all the elements left about a table, because apparently amplify doesn't always remove everything, so if you know how to do let me know ! @przemekblasiak and @DivonC, is your lambda's ARN similar to its execution role's ARN? For more advanced use cases, you The same example above now means: Owners can read, update, and delete. AWS AppSync does not store any data so therefore you must store this authorization metadata with the resources so that permissions can be calculated. You can use private with userPools and iam. curl as follows: You can implement your own API authorization logic using an AWS Lambda function. data source and create a role, this is done automatically for you. We thought about adding a new option similar to what you have mentioned above but we realized that there is an opportunity to refine the public and private behavior for IAM provider. Partner is not responding when their writing is needed in European project application, Change color of a paragraph containing aligned equations. First, install the AWS Amplify CLI if you do not already have it installed: Next, configure the cli with your correct credentials: If this is your first time using AWS, check out this video to see how to get these credentials and set up the CLI. Perhaps that's why it worked for you. For more information on attaching policies Other customers may have custom or legacy OAuth systems that are not fully OIDC compliant, and need to directly interact with the system to implement authorization. the main or default authorization type, you cant specify them again as one of the additional When I disable the API key and only configure Cognito user pool for auth on the API, I get an 401 Unauthorized. encounter when working with AWS AppSync and IAM. Use the following information to help you diagnose and fix common issues that you might AWS AppSync supports a wide range of signing algorithms. Click here to return to Amazon Web Services homepage, a backend system powered by an AWS Lambda function. You can use the deniedFields array to specify which operations the user is not allowed to access. API (GraphQL) Setup authorization rules @auth Authorization is required for applications to interact with your GraphQL API. An alternative approach would be to allow users to opt out of this IAM authorization change since it doesn't look like it is necessary in order to use the rest of the v2 transformer changes, but I'm not sure how much appetite AWS has to consider that? 542), How Intuit democratizes AI development across teams through reusability, We've added a "Necessary cookies only" option to the cookie consent popup. { allow: groups, groupsField: "editors", operations: [update] } Thanks for letting us know this page needs work. reverting to amplify-cli@4.24.2 and re-running amplify push fixes the issue. Since we ran into this issue we reverted back to the v1 transformer in order to not be blocked, and so our next attempt to move to v2 is back in our backlog but we hope to work on in the next 4-6 weeks if we're unblocked. Newbies like me: Keep in mind the role name was the short one like "trigger-lambda-role-oyzdg7k3", not the full ARN. A Lambda function must not return more than 5MB of contextual data for Finally, here is an example of the request mapping template for editPost, If you've got a moment, please tell us how we can make the documentation better.

The full ARN form should be used when two APIs share a lambda function authorizer We are experiencing this problem too. additional ', // important to make sure we get up-to-date results, // Helps log out errors returned from the AppSync GraphQL server. Here is an example of what I'm referring to but this is for lambdas within the same amplify project. UpdateItem, which would be a bit more verbose in an example, but the same In the APIs dashboard, choose your GraphQL API. This issue has been automatically locked since there hasn't been any recent activity after it was closed. the following mapping template: This returns all the values responses, even if the caller isnt the author who created This makes sense to me because IAM access is guarded by IAM policies assigned to the Lambda which provide coarse or fine-grained AppSync API access. Create a GraphQL API object by calling the UpdateGraphqlApi API. }, We are getting "Not Authorized to access updateBroadcastLiveData on type Mutation", edit: it was fixed as soon as I changed: the AWS AppSync GraphQL API. In addition to my frontend, I have some lambdas (managed with serverless framework) that query my API.

Please open a new issue for related bugs. authorized. Some AWS services allow you to pass an existing role to that service instead of creating a new service role or service-linked role. The private authorization specifies that everyone will be allowed to access the API with a valid JWT token from the configured Cognito User Pool. The Please help us improve AWS. If you haven't already done so, configure your access to the AWS CLI. Without this clarification, there will likely continue to be many migration issues in well-established projects. We invoke a GraphQL query or mutation from the client application, passing the user identity token along with the request in an authorization header (the identity automatically passed along by the AWS AppSync client). I have set my API (amplify update api) to use Cognito User Pools as the default auth, and to use API key as a secondary auth type. The Lambda authorization token should not contain a Bearer scheme prefix. To retrieve the original OIDC token, update your Lambda function by removing the removing the random prefixes and/or suffixes from the Lambda authorization token. This is stored in Using AppSync, you can create scalable applications, including those requiring real . the root Query, Mutation, and Subscription 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? This will use the "AuthRole" IAM Role. Why is the article "the" used in "He invented THE slide rule"? AppSync is a managed service that uses GraphQL so that applications can easily get only the data they need. They had an appsync:* on * and Amplify's authRole and unauthRole a appsync:GraphQL on *. following CLI command: When you add additional authorization modes, you can directly configure the When used in conjunction with amplify add auth the CLI generates scoped down IAM policies for the Authenticated role automatically. For more information, The deniedFields array is a list of fields that the request is not allowed to access. This will use the "UnAuthRole" IAM Role. My goal was to give everyone read access and to give write access to Owner+Admin+Backend, this is why i intentionally omitted read in operations.
