How to setup Lambda Authorizer for a REST API added in Amplify,

0

I cannot find a way to set up Lambda Authorizer for the Rest API I added using AWS amplify in my amplify app. The only options it shows are for authenticated and unauthenticated users and does not let me configure anything else.

Maybe it can be done with overrides.ts but I could not find an example of how to do it, any guidance will be appreciated.

This is how I solved it. amplify override API to create an overrides.ts file and add the following.

 // Create a lambda authorizer
  resources.restApi.addPropertyOverride("Body.securityDefinitions", {
    Custom: {
      type: "apiKey",
      name: "Authorization",
      in: "header",
      "x-amazon-apigateway-authtype": "custom",
      "x-amazon-apigateway-authorizer": {
        type: "request",
        authorizerUri: {
          "Fn::Sub":
            "arn:aws:apigateway:${AWS::Region}:lambda:path/2015-03-31/functions/arn:aws:lambda:${AWS::Region}:${AWS::AccountId}:function:${AuthorizerFunctionName}/invocations",
        },
        authorizerResultTtlInSeconds: 300,
        identitySource: "method.request.header.Authorization",
      },
    },
  });

  // For every path in your REST API, add the authorizer for all methods
  for (const path in resources.restApi.body.paths) {
    resources.restApi.addPropertyOverride(
      `Body.paths.${path}.x-amazon-apigateway-any-method.parameters`,
      [
        ...resources.restApi.body.paths[path]["x-amazon-apigateway-any-method"]
          .parameters,
        {
          name: "Authorization",
          in: "header",
          required: false,
          type: "string",
        },
      ]
    );
    // Use your new Cognito User Pool authorizer for security
    resources.restApi.addPropertyOverride(
      `Body.paths.${path}.x-amazon-apigateway-any-method.security`,
      [ { Custom: [], }, ]
    );
  }
