Logging AWS AppSync API calls using AWS CloudTrail, AppSync author: String} type Query {fetchCity(id: ID): City}Note that author is the only field not required.. Provisioning Resources. In the following example using DynamoDB, suppose youre using the preceding blog post Here's an example in JSON: API keys are configurable for up to 365 days, and you can extend an existing expiration date for up to As you can see, the response from your Lambda function allows you to implement custom access control, deny access to specific fields, and securely pass user specific contextual information to your AppSync resolvers in order to make decisions based on the requester identity. Looking at the context.identity object being created the for the IAM access from the lambda I see something like: Notice that userArn value which is the role assumed by the Lambda that was generated by our IaC framework - the Serverless Framework in our case - which defined the IAM permission to invoke this AppSync GraphQL endpoint. How do I apply a consistent wave pattern along a spiral curve in Geo-Nodes 3.3? getPost field on the Query type. The @auth directive allows the override of the default provider for a given authorization mode. Well occasionally send you account related emails. 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. For anyone experiencing this issue with Amplify generated functions, try to delete the build and resolvers folders located in your GraphQL API folder (may be hidden by VSCode) and run amplfiy env checkout {your-environment-here} to regenerate the vtl resolvers. 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". Find centralized, trusted content and collaborate around the technologies you use most. resolver: The value of $ctx.identity.resolverContext.apple in resolver For example, take the following schema that is utilizing the @model directive: In this case, Mary's policies must be updated to allow her to perform the iam:PassRole action.

Finally, here is an example of the request mapping template for editPost, We're sorry we let you down. Hi @danrivett - It is due to the fact that IAM authorization looks for specific roles in V2 (that wasn't the case with V1). this: Note that you can omit the @aws_auth directive if you want to default to a Sorry for not replying. AWS AppSync recognizes the following keys returned from You can start using Lambda authorization in your existing and new APIs today in all the regions where AppSync is supported. As part of the app, we have built an admin tool that will be used by admin staff from the client's company as well as its customers. 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. 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. & Request.ServerVariables("QUERY_STRING") 13.global.asa? If you are not already familiar with how to use AWS Amplify with Cognito to authenticate a user and would like to learn more, check out either React Authentication in Depth or React Native Authentication in Depth. 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. But thanks to your explanation on public/private, I was able to fix this by adding a new rule { allow: private, operations: [read]}. These basic authorization types work for most developers. These regular expressions are used to validate that an rules: [ Create a GraphQL API object by running the update-graphql-api command. following applies: If the API has the AWS_LAMBDA and AWS_IAM authorization Marking this as feature request. the API ID and the authentication token. A regular expression that validates authorization tokens before the function is called 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? need to give API_KEY access to the Post type too. Perhaps that's why it worked for you. AWS AppSync requires the JWKS to Why can't I read relational data when I use iam for auth, but can read when authenticated through cognito user pools. process, Resolver . 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. process 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. @danrivett - Thanks for the details. For more information on attaching policies by your OIDC provider for controlling access. ttlOverride value in a function's return value. For Region, choose the same Region as your function.

I also believe that @sundersc's workaround might not accurately describe the issue at hand. }. If you want to restrict access to just certain GraphQL operations, you can do this for The resolver code is triggered in AppSync and an authorized action or operation is executed accordingly against the data source, in this case an Amazon DynamoDB table. your provider authorizes multiple applications, you can also provide a regular expression I just want to be clear about what this ticket was created to address. Next, create the following schema and click Save:. rules: [ Some AWS services allow you to pass an existing role to that service instead of creating a new service role or service-linked role. 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. For example, if the following structure is returned by a In this screen, choose City as the type, and create an additional index with an Index name of author-index and a primary key of author.
