AWS CloudFormation/API Gateway gives 'Invalid Resource identifier specified'
12,567
Solution 1
ResourceId must be a reference to a cloudformation resource, not a simple string.
e.g.
ResourceId:
Ref: UsersResource
Solution 2
I figured that actually it was the RestApiId which needed to be a reference too:
"RestApiId": {
"Ref": "MyApi"
},

I have been trying to use CloudFormation to deploy to API Gateway, however, I constantly run into the same issue with my method resources. The stack deployments keep failing with 'Invalid Resource identifier specified'.
Here is my method resource from my CloudFormation template:
"UsersPut": { "Type": "AWS::ApiGateway::Method", "Properties": { "ResourceId": "UsersResource", "RestApiId": "MyApi", "ApiKeyRequired": true, "AuthorizationType": "NONE", "HttpMethod": "PUT", "Integration": { "Type": "AWS_PROXY", "IntegrationHttpMethod": "POST", "Uri": { "Fn::Join": ["", ["arn:aws:apigateway:", { "Ref": "AWS::Region" }, ":lambda:path/2015-03-31/functions/", { "Fn::GetAtt": ["MyLambdaFunc", "Arn"] }, "/invocations"]] } }, "MethodResponses": [{ "StatusCode": 200 }] } }Is anyone able to help me figure out why this keeps failing the stack deployment?
UPDATE: I forgot to mention that I had also tried using references to add the resource ID, that also gave me the same error:
"UsersPut": { "Type": "AWS::ApiGateway::Method", "Properties": { "ResourceId": { "Ref": "UsersResource" }, "RestApiId": "MyApi", "ApiKeyRequired": true, "AuthorizationType": "NONE", "HttpMethod": "PUT", "Integration": { "Type": "AWS_PROXY", "IntegrationHttpMethod": "POST", "Uri": { "Fn::Join": ["", ["arn:aws:apigateway:", { "Ref": "AWS::Region" }, ":lambda:path/2015-03-31/functions/", { "Fn::GetAtt": ["MyLambdaFunc", "Arn"] }, "/invocations"]] } }, "MethodResponses": [{ "StatusCode": 200 }] } }Here is the full CloudFormation template:

user3067870 almost 7 yearsYea sorry I did also try using references but that gave me the same error.

jens walter almost 7 yearsHow did you define your resource? Can you post a more complete version of the CF-template?

user3067870 almost 7 yearsI have updated the question with the full template, thanks.
