OCAPI Batch request to get all Orders after a Certain Date

Question

I'm New to SFCC OCAPI. My purpose is to Export all Orders from "development.demandware.net" after certain date and this can happen Quite frequently like once in every 2 days. I'm currently using Python to achieve this using the endpoint "s/{{SITEID}}/dw/shop/v18_1/order_search". The problem is One call is getting me only 25 Records. Again i have change the query from dynamically to start from RecordNo 26 for the next call. So, If I have like 10,000 records, it makes upto 400 calls everytime the scirpt runs. The alternative options i'm aware of is:

• OCAPI Batch requests

• OCAPI Export job (Tried this, but haven't got enough knowledge to set this up)

So, I'd like to know if my purposed is achievable using the batch request. I tried to do this using the documentation. And, the response was 200 with no response body using the below code.

  url = f"https://{DOMAIN}/s/-/dw/batch"
url_param = {'client_id': CLIENT_ID}
header = {'Authorization': 'Bearer ' + token, 
          'Origin': f'https://{DOMAIN}', 
          'Content-Type': 'multipart/mixed;boundary=23dh3f9f4',
          'x-dw-http-method': 'POST',
          'x-dw-resource-path': 's/{{SITEID}}/dw/shop/v18_8/order_search'}
body = """
    { 
        "query" :
        { 
          "filtered_query": {
                "query": { "match_all_query": {} },
                "filter": {
                    "range_filter": {
                                "field": "creation_date",
                                "from": "%s",
                                "from_inclusive": true
                    }
                }
            }
        },
        "select" : "(**)",
        "sorts": [{
            "field": "order_no",
            "sort_order": "asc"
            }],
        "start": %s
    }""" %(RETRIVE_RECORDS_FROM, startRecordFrom)
        
response = requests.post(url, params = url_param, headers = header, data = body)

My code doesn't have a x-dw-content-id as the above is an initial request. If its possible to achieve my purpose,

• how should my sub-request looks like.?
• And after that how do i retrieve the data of my request.? is there any endpoint i should use to get the batch results.?

I maybe asking for too much information. But, i couldn't find much information about this online so had to ask every question i have in one post.

My question might look similar to this question "Salesforce Commerce Cloud/Demandware - OCAPI query orders by date range", But I'm looking for information about batch requests and also to reduce the number of API calls.

Thanks in advance.
