Create api-gateway lambda integration using aws-cli

you can run aws apigateway get-resources to get the resource-id

aws apigateway get-resources --rest-api-id 42ku123id8u3a --region us-east-1

It will return a JSon like

{
    "items": [
        {
            "path": "/resource/xxx",
            "resourceMethods": {
                "POST": {}
            },
            "id": "_yourresourceid_",
            "pathPart": "xxx",
            "parentId": "ai5b02"
        }
    ]
}

you can take the id from this JSon and use it on your command for aws apigateway put-integration
