You can do something like:
Copy code
const queue = sst.Queue(...);
const topic = sst.Topic(...);
topic.snsTopic.addSubscription(new subscriptions.SqsSubscription(queue.sqsQueue));j
José Ribeiro
05/26/2021, 10:22 PMcool, I’ll try that out. Thank you @Frank!
José Ribeiro
05/26/2021, 10:22 PMalso — do you support creating service proxy integrations? e.g. Api Gateway publishing to SNS directly
José Ribeiro
05/26/2021, 10:33 PMlike what’s defined by AwsIntegration in https://docs.aws.amazon.com/cdk/api/latest/docs/aws-apigateway-readme.html#integration-targets

Frank
05/26/2021, 10:33 PM
Yeah..i’m looking at the docs too
Frank
05/26/2021, 10:34 PM
are you using the
sst.Apij
José Ribeiro
05/26/2021, 10:36 PMright now I’m deciding how to build this 😄 I’m happy to put a lambda in the middle to receive the data we need from an HTTP endpoint and publish to SNS. But I’d much rather avoid creating a lambda only to do this and just forward it from API Gateway to SNS directly

Frank
05/26/2021, 10:40 PM
Yeah. So according to this page - https://docs.aws.amazon.com/apigateway/latest/developerguide/http-api-develop-integrations-aws-services-reference.html#SQS-SendMessage
HTTP Api to SNS is not supported.

Maybe see if EventBridge works for you?

José Ribeiro
05/26/2021, 10:45 PMhmm, I’m sure I’ve done this by hand before directly in Api Gateway, maybe not directly using a service integration? I guess I was just using a mapping template and then forwarding a POST directly to SNS

Frank
05/26/2021, 10:46 PM
Oh, I think you were probably using REST Api.
j
José Ribeiro
05/26/2021, 10:47 PMoh sorry, that could indeed be it. I guess I was not educated enough in the different api gateway api types
José Ribeiro
05/26/2021, 10:50 PMso is it the difference that the HTTP api cannot do an integration request, whereas the REST Api can?

HTTP Api integrates with a limited number of AWS services. Based on the link above, it seems HTTP Api can integrate with SQS, Step Functions and a couple of other AWS services.
Frank

SNS isn’t in the list.

José Ribeiro
05/26/2021, 11:03 PMright — I’m ok with using a REST Api, I’m just not so sure whether the ApiGatewayV1Api construct allows for that, or whether I should fall back to using bare CDK if I wanted to accomplish that
José Ribeiro
05/26/2021, 11:04 PMof course I’m taking for granted I could just use a HTTP Api and route to SNS through lambda as well, just trying to understand what’s possible
f
Frank
05/26/2021, 11:06 PM
yeah.. I’m biased towards using HTTP Api. But if you were to go with REST Api, you’d need to use bare CDK for the time being.

@José Ribeiro in v0.22.0, I added the ability for Queue to subscribe to a Topic. It should simplify ur code a bit:
Copy code
const queue = sst.Queue(...);
const topic = sst.Topic(this, "MyTopic", {
subscribers: [queue],
});
