I'm new to AWS SAM deployment. I have a use case to automate the deployment using SAM AWS. Having a Rest API GW with another HTTP endpoint invocation. I searched pretty more docs but I didn't find any solution for this. Could you mind suggest me how to do this case?

Thanks in advance. Karthikeyan B

Sample template you can try for creating integration -

AWSTemplateFormatVersion: '2010-09-09'
Transform: AWS::Serverless-2016-10-31
Description: AWS SAM template with a HTTP integration
Resources:
  ApiGatewayApi:
    Type: AWS::Serverless::Api
    Properties:
      StageName: prod
      DefinitionBody: {
        "swagger": "2.0",
        "info": {
          "version": "1.0"
        },
        "paths": {
          "test": {
            "get": {
              "produces": [
                "application/json"
              ],
              "responses": {
                "200": {
                  "description": "200 response"
                }
              },
              "x-amazon-apigateway-integration": {
                "responses": {
                  "default": {
                    "statusCode": "200"
                  }
                },
                "credentials": "arn:aws:iam::account-id:role/role-name",
                "uri": "https://www.example.com",
                "passthroughBehavior": "when_no_match",
                "httpMethod": "GET",
                "type": "http_proxy"
              }
            }
          }
        }
    }

Deploy the template using CLI -

$ sam deploy --stack-name httpProxy -t httpProxy.yaml --capabilities CAPABILITY_IAM

  1. You can build a hello world SAM app in a few clicks using the AWS toolkit in VS Code as shown in my blog post here.
  2. Then, modify the generated SAM template (template.yaml) to integrate with an HTTP API instead of Lambda.
  3. Add a buildspec.yml to your codebase & build a CI/CD pipeline using AWS CodeBuild & CodePipeline as shown in my blog post here.
