      The program never ran and line 30 is another syntax error.

  they probably fingerprint your client, in which case you'll need to use selenium or something similar

    That won't help. They block IP addresses too. Just from browsing around a lot at home you will get blocked at your home. Just be patient. They'll stop being stupid eventually. I've seen this many times before with many different retailers.

      having a dynamic ip address has some advantages :)

  You can just use their API (238473) was from the URL known as the stockcode:
  https://www.woolworths.com.au/apis/ui/product/detail/238473

  Yes, you can use their API. Ihave created a Google Apps Script function to pull the price and various other pieces of information from their API, feel freet o use the below.

  function WOWData(Article, Attribute){
    var url = "https://www.woolworths.com.au/apis/ui/products/" + Article;
    var result = UrlFetchApp.fetch(url).getContentText();
    var JSONResponse = JSON.parse(result);
    if (JSONResponse.pageCount===0) {
      return "";
    }
    else {
      switch (Attribute) {
        case "Barcode":
        return JSONResponse[0].barcode; 
        break;
        case "Price":
        return JSONResponse[0].Price; 
        break;
        case "InstorePrice:":
        return JSONResponse[0].InstorePrice; 
        break;
        case "Name":
        return JSONResponse[0].Name; 
        break;
        case "IsNew":
        return JSONResponse[0].IsNew; 
        break;
        case "IsOnSpecial":
        return JSONResponse[0].IsOnSpecial; 
        break;
        case "InstoreIsOnSpecial":
        return JSONResponse[0].InstoreIsOnSpecial; 
        break;
        case "IsEdrSpecial":
        return JSONResponse[0].IsEdrSpecial; 
        break;
        case "SavingsAmount":
        return JSONResponse[0].SavingsAmount; 
        break;
        case "WasPrice":
        return JSONResponse[0].WasPrice; 
        break;
        case "IsInStock":
        return JSONResponse[0].IsInStock; 
        break;
        case "Brand":
        return JSONResponse[0].Brand; 
        break;
        case "IsInFamily":
        return JSONResponse[0].IsInFamily; 
        break;
        case "tgawarnings":
        return JSONResponse[0].AdditionalAttributes.tgawarnings; 
        break;
        case "tgawarning":
        return JSONResponse[0].AdditionalAttributes.tgawarning; 
        break;
        case "vendorarticleid":
        return JSONResponse[0].AdditionalAttributes.vendorarticleid; 
        break;
        case "vendorcostprice":
        return JSONResponse[0].AdditionalAttributes.vendorcostprice; 
        break;
        case "Promotion":
        return JSONResponse[0].HeaderTag.Content; 
        break;
      }
    }
  }

  Hi Jeremy, were you ever able to get this working? Maybe we can work on it together; I have basic Python skills for scraping if that helps.

  Edit: PS. This is a longshot, but does anybody call you "JB"?

    Hi mate,

    I know this is an old thread, but would you happen to have any resources to help me learn how to cobble something together to price scrape some camera sites?

      Hi, do you write in Python? Or alternatively you could try Octoparse with the free trial.

      • 

        wittyusername on 11/10/2021 - 08:26

        Cheers man, I am giving octoparse a crack. Seems good so far!

  I wrote a code to check for my favourite items at woolies every day. My code used to call their apis/ui/product/detail to retrieve the json data, but they have implemented security checks recently. Upon closer examination, the json data is also embedded in the html source, e.g. https://www.woolworths.com.au/shop/productdetails/439768/kbs-prawn-gyoza

  It would contain this at the end of the html source:

  ....:0,&q;InstoreSavingsAmount&q;:0,&q;WasPrice&q;:22.7,&q;InstoreWasPrice&q;:22.7,&q;QuantityInTrolley&q;:0,.......

  So I would first strip off the &q;, then just look for ,FieldName:(.*), and extract the value using regex.

    replace

    &q; -> "
    &s; -> '
    &l; -> <
    &g; -> >
    &a; -> &

    then use a json library to parse the resulting json string

      Thanks! Do you know what those things are called? They're not standard html entities. I would've preferred to clean them up using a library rather than manually.

      • 

        c64 on 22/08/2021 - 13:23

        they are custom html entities that woolworths has decided to use

    Hi mate,

    I know this is an old thread, but would you happen to have any resources to help me learn how to cobble something together similar to what you've done? It'd be for camera sites who I don't think protect their prices as vigorously as woollies seem to.

    Cheers.

      basically you first need to figure out where the data is located. I used the browser's developer mode and look at the html source and also look at what other requests it makes, like on this screenshot: https://pasteboard.co/4P2IRcMLijB5.png

      Then just write code in your favourite language to make the same GET / POST http request. Usually the data is in json format.

  Hi JeremyDealFiend,

  I've been working on a tool to access the Woolworths API using the R programming language. If you're interested, it's over here
