Hey @green-dentist-53234 I read an article on being able to use this type of architecture for things like chat applications https://www.enlabsoftware.com/development/how-to-create-real-time-chat-applications-using-websocket-apis-in-api-gateway.html

Hi @broad-dog-22463, thank you for the link, I have been reading these articles for the last few days. I can even click the application in the AWS console, but I can't programing pulumi correctly to create what I want. Specifically, I don't know how to connect websocket api with integration now. I'm trying something similar:

new aws.apigatewayv2.Integration ('lambdaDefaultIntegration', {
    apiId: apigw.id,
    integrationType: 'AWS',
    integrationUri: lambda.arn
});

But it doesn't work at all (it doesn't even go deploy, it ends in Invalid function ARN or invalid uri) But when I try this

new aws.apigatewayv2.Integration ('lambdaDefaultIntegration'), {
    apiId: apigw.id,
    integrationType: 'AWS_PROXY',
    integrationUri: lambda.arn
});

deploy will work, but I don't see the link between integration and lambda in the AWS console (you can see in image).

The following aws api gateway is a guide that can help you out.

Thank you gentlemen for the advice. In the end, my problem was that I lacked permission to invoke lambda for the api gateway 🤦

Glad it was something small!! Sorry I missed your response earlier

perfectly fine, personal experience is non-transferable
