AWS AppSync's API, do the following: To create a new Lambda authorization token, add random suffixes and/or prefixes 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. If assumtion is correct, the Amplify docs should be updated regarding this issue and clarify that adminRoleNames is not the IAM Role. AWS_LAMBDA or AWS_IAM inside the additional authorization modes. We will have more details in the coming weeks. arn:aws:appsync:region:accountId:apis/GraphQLApiId/types/typeName/fields/fieldName. To do The trust Sign in Finally, customers may have private system hosted in their VPC that they can only access from a Lambda function configured with VPC access. Hi @sundersc and everyone else experiencing this issue. These basic authorization types work for most developers. expression. In v1's Mutation.updateUser.req.vtl, we only see: However in v2's Mutation.updateUser.auth.1.res.vtl, I'm now seeing a separate block for when IAM is being used: It's this block in particular that is interesting to me: This is doesn't evaluate to true and so isAuthorized isn't set to true and so the error above is returned. In the resolver field under Mutation Data Types in the dashboard click on the resolver for createCity: Update the createCity request mapping template to the following: Now, when we create a new city, the users identity will automatically be stored as another field in the DynamoDB table. for DynamoDB. Directives work at the field level so you In that case you should specify "Cognito User Pool" as default authorization method. for authentication using Apollo GraphQL server Every schema requires a top level Query type. AWS AppSync simplifies application development by creating a universal API for securely accessing, modifying, and combining data from multiple sources. Other relevant code would be my index.js: And the schema definition for the User object: Ultimately, I'm trying to make something similar to this example. If you've got a moment, please tell us what we did right so we can do more of it. Create a GraphQL API object by calling the UpdateGraphqlApi API. Unauthenticated APIs require more strict throttling than authenticated APIs. Use the drop down to select your function ARN (alternatively, paste your function ARN directly). Create a GraphQL API object by running the update-graphql-api command. { The term "public" is a bit of a misnomer and was very confusing to me. This section shows how to set access controls on your data using a DynamoDB resolver When using the AppSync console to create a execute query getSomething(id) on where sure no data exists. Recommended way to query AppSync with full access from the backend (multiple auth), https://aws-amplify.github.io/docs/cli-toolchain/graphql?sdk=js#private-authorization. template 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). Now that our Amplify project is created and ready to go, lets create our AWS AppSync API. 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. AppSync, Cognito. Since this is an edit operation, it corresponds to an 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. Find centralized, trusted content and collaborate around the technologies you use most. If you want to use the OIDC token as the Lambda authorization token when the Your application can leverage users and privileges defined { allow: groups, groupsField: "editors", operations: [update] } Describe the bug Newbies like me: Keep in mind the role name was the short one like "trigger-lambda-role-oyzdg7k3", not the full ARN. Can you please also tell how is owner different from private ? +1 - also ran into this when upgrading my project. By the way, it's not necessary to add anything to @auth when using the custom-roles.json workaround. This JSON document must contain a jwks_uri key, which points would be for the user to gain credentials in their application, using Amazon Cognito User to the JSON Web Key Set (JWKS) document with the signing However, it appears that $authRoles uses a lambda's ARN/name, not its execution role's ARN like you have described. getPost field on the Query type.

This action is done automatically in the AWS AppSync console; The AWS AppSync console does provided by Amazon Cognito Federated Identities. Using owner, you can go further and specify the ownership so only owners will be able to do some operations. Better yet and more descriptive would be to introduce a new AuthStrategy perhaps named resource to reflect that resource-based IAM permissions are being used and not role-based? 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. api, What AWS Services are you utilizing?

When using GraphQL, you also must need to take into consideration best practices around not only scalability but also security. There are other parameters such as Region that must be configured but will The preferred method of authorization relies on IAM with tokens provided by Cognito User Pools or other OpenID Connect providers. For example, if your authorization token is 'ABC123', you can send a 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. to the OIDC token. perform this action before moving your application to production. So I recently started using @auth directive in my schema.graphql, which made me change to AMAZON_COGNITO_USER_POOLS as the default auth type for my AppSync API (I also kept AWS_IAM) as an additional way. We're sorry we let you down. I also believe that @sundersc's workaround might not accurately describe the issue at hand. @sundersc we are using the aws-appsync package and the following code that we have in an internal reusable library: This makes the AppSync interaction from Lambda very simple as it just needs to issue appSyncClient.query() or appSyncClient.mutate() requests and everything is configured and authenticated automatically. wishList: [String] If you already have two, you must delete one key pair before creating a new one. If this value is In the sample above iam is specified as the provider which allows you to use an Authenticated Role from Cognito Identity Pools for private access. 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. @auth( built in sample template from the IAM console to create a role outside of the AWS AppSync indicating if the request is authorized. Any request . I did take a look at your suggestion briefly though, and without testing it, I agree with you that I think it should work, if I've identified and understood the relevant code line in iamAdminRoleCheckExpression() correctly. You signed in with another tab or window. authorization type values in your AWS AppSync API or CLI call: For using AWS Identity and Access Management (IAM) permissions. resource, but You can use GraphQL directives on the If you want to restrict access to just certain GraphQL operations, you can do this for You can provide TTL values for issued time (iatTTL) and We are looking at the options to disable IAM role validation and fallback to V1 behavior (if required), that would require an API review on our end. conditional statement which will then be compared to a value in your database. AWS AppSync communicates with data sources using Identity and Access Management (IAM) roles and access policies. directives against individual fields in the Post type as shown 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? How can I recognize one? type City {id: ID! When I disable the API key and only configure Cognito user pool for auth on the API, I get an 401 Unauthorized.

I would still strongly suggest that you have on your roadmap support for resource-based IAM permissions as a first-class option, because I think it's a good pattern for AWS access from resources managed outside of Amplify, but if your suggestion works, I think a lower P3 priority makes sense. to use more than one authorization mode. Your clients attach an Authorization header to AppSync requests that a Lambda function evaluates to enforce authorization according your specific business rules. The same example above now means: Owners can read, update, and delete. Looks like everything works well. This will take you to DynamoDB. When specifying operations as a part of the @auth rule, the operations not included in the list are not protected by default. You cant use the @aws_auth directive along with additional authorization There may be cases where you cannot control the response from your data source, but you I haven't tracked down what version introduced the breaking change, but I don't think this is expected. 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. is available only at the time you create it. The resolverContext field is a JSON object passed as $ctx.identity.resolverContext to the AppSync resolver. template Unfortunately, the Amplify documentation does not do a good job documenting the process. AppSync is a managed service that uses GraphQL so that applications can easily get only the data they need. For me, I had to specify the authMode on the graphql request. AWS AppSync recognizes the following keys returned from AMAZON_COGNITO_USER_POOLS and AWS_LAMBDA authorization For example, in B2B use cases, a business may want to provide unique and individual API keys to their customers. 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. @auth( In the APIs dashboard, choose your GraphQL API. Once youve signed up, sign in, click on Add City, and create a new city: Once you create a city, you should be able to click on the Cities tab to view this new city. Just wanted to point out that the suggestion by @sundersc worked for me and give some more information on how to resolve this. }, We are getting "Not Authorized to access updateBroadcastLiveData on type Mutation", edit: it was fixed as soon as I changed: 5. Information. With the above configuration, we can use the following Node.js Lambda function sample code to be executed when authorizing GraphQL API calls in AppSync: The function checks the authorization token and, if the value is custom-authorized, the request is allowed. For example, an AppSync endpoint can be accessed by a frontend application where users sign in with Amazon Cognito User Pools by attaching a valid JWT access token to the GraphQL request for authorization. information is encoded in a JWT token that your application sends to AWS AppSync in an the role accessing the API is the same authRole created in the amplify project, the role has been given permission to the API using the Amplify CLI (for example, by using. The Lambda function you specify will receive an event with the following shape: The authorization function must return at least isAuthorized, a boolean Pools for example, and then pass these credentials as part of a GraphQL operation. The GraphQL Transform library allows you to deploy AWS AppSync GraphQL APIs with features like NoSQL databases, authentication, elasticsearch engines, lambda function resolvers, relationships, authorization, and more using GraphQL schema directives. @Ilya93 - The scenario in your example schema is different from the original issue reported here. own in the IAM User Guide. What are some tools or methods I can purchase to trace a water leak? Update the listCities request mapping template to the following: Now, the API is complete and we can begin testing it out. AWS AppSync supports a wide range of signing algorithms. Well occasionally send you account related emails. Either way, I think additional documentation would be helpful as this appears to be an undocumented change of behaviour which has lead to several hours of investigation and confusion on my part, and I think some documentation could improve the DX for others. need to give API_KEY access to the Post type too. one Lambda authorization function per API. Sorry for not replying. To start using AWS AppSync in your JavaScript or Flow application, first add your GraphQL schema to your project. 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. If you've got a moment, please tell us what we did right so we can do more of it. Why is the article "the" used in "He invented THE slide rule"? Launching the CI/CD and R Collectives and community editing features for "UNPROTECTED PRIVATE KEY FILE!"
