Prerequisite:

A working SQS with input and output queues.
A working SDK project.
Template SQS global consumer project.

Step 1: Clone OL SQS connector

Pull sqs-clobal-consumer repo from Openlegacy GitHub (ask permissions if needed).
Got to the project directory and build it with maven ./mvnw clean -DskipTests source:jar install.

Step 2: Create an API project

Import ol-sqs-global-consumer-template to your workspace.
Create an API project from ol-sqs-global-consumer-template.
Add an SDK project and Finish.

Step 3: customize your API project

Go to the API project's pom.xml and change the version according to your IDE.

2. Go to project’s application.yml file and edit the SQS configuration

ol:
 # SQS configurations #
  sqs:
     global-consumer: 
      access-key: #your AWS access-key 
      secret-key: # your AWS secret-key 
      region: # the region in your AWS  
      from-queue: #input queque 
      to-queue: #output queue

3. Generate service from SDK.

Now you have an API with SQS connector.

Step 4: Test your SQS API

Go to AWS SQS and send a message from the input queue, for example (in case of using CICS MF ItemDetails example):
{ "itemNum": 1000 "method": "item" }

“method”= the service’s name.

2. Go to the output queue and you would receive the service’s output as a message.
