Just used this in Firefox 85.0.2.
Great script.
Had to change setting to Always Automatically Download files in Firefox settings because it just prompted a lot of Download File windows.
Please add this to the instructions.

I wasn't able to find this setting in Firefox, and the pasted code from @iampranavthesi generated the following errors:

Cross-Origin Request Blocked: The Same Origin Policy disallows reading the remote resource at https://my.adp.com/v1_0/O/A/payStatements?adjustments=yes&numberoflastpaydates=300. (Reason: header ‘access-control-allow-origin’ is not allowed according to header ‘Access-Control-Allow-Headers’ from CORS preflight response).

Any ideas?

@eraser215 were you already logged in to my.adp.com?
You can try these steps if it helps you out -

1. After login to my.adp.com open this link https://my.adp.com/v1_0/O/A/payStatements?adjustments=yes&numberoflastpaydates=300 in a new tab. (This will be a JSON response body)
   (You will not get CORS issue if you try on this link)
2. Open Dev tools -> Console and then paste the first code block to load up the JSZip library
3. Then paste the second code block to start the download of every payslip. (It is going to take a while depending on how many are there to download)
4. Lastly, paste the last code block to trigger the download of the zip file.

Paste the 3 code blocks one at a time and not as one script together.

Tested in Chrome v89 can't say about Firefox but should be similar.

This was helpful and worked as described after using @iampranavsethi modified instructions.

Updated Script as of this date(Tested in chrome Version 94.0.4606.81 (Official Build) (64-bit))

        xhttp.onreadystatechange = function() {
            if(this.readyState == 4 && this.status == 200) {
                zip.folder(year).file(date + ".pdf", this.response)
            }
        };
        xhttp.open('GET', url, true);

zip.generateAsync({type : 'base64'}).then(function (base64) {
var a = document.createElement('a');
a.download = 'paystubs.zip';

});

This worked very nicely, thanks!

Works great after adding the sleep step - thank you!

Thanks for this. I found that the Zip version didn't quite work if you had more than one paystub on the same day, so I made a small modification to the callback to append an index to the filename and now that works.

Hi, I've just used the original script in Chrome and as before it stops after 10 downloads. I added a simple fix to sleep between downloads and it then was able to download all 159 of my payslips without any problems. (Note I also added some logging so I can see progress.)

Here is the updated code:

var xhr = new XMLHttpRequest();
xhr.open('GET', 'https://my.adp.com/v1_0/O/A/payStatements?adjustments=yes&numberoflastpaydates=300');
xhr.setRequestHeader("Access-Control-Allow-Origin", "*"); // CORS policy
xhr.onload = async function() {
    if (xhr.status === 200) {
        var rawData = JSON.parse(xhr.responseText);
        console.log('Number of items:', rawData.payStatements.length);
        for (var index = rawData.payStatements.length - 1; index >= 0; --index) {
            var entry = rawData.payStatements[index];
            var url = "https://my.adp.com" + entry.statementImageUri.href.substring(3);
            console.log("Downloading:", url);
            var a = document.createElement('a');

            var trueIndex = (rawData.payStatements.length - index);
            if (trueIndex < 10) {
                trueIndex = "00" + trueIndex;
            } else if (trueIndex < 100) {
                trueIndex = "0" + trueIndex;
            }

            a.download = "payslip.no." + trueIndex + ".from." + entry.payDate + ".pdf";
            a.href = url;
            document.body.appendChild(a);
            a.click();
            delete a;

            await new Promise(r => setTimeout(r, 1000));
        }
    } else {
        console.log('Request failed.  Returned status of ' + xhr.status);
    }
};
xhr.send();

Updated version for 2024:

You need to get your OID by inspecting web requests, and replace YOUR_OID_HERE. I tried to make it generic by calling this API: https://my.adp.com/myadp_prefix/myadpapi/core/v1/version which returns the OID, but the API has some special CORs protection I couldn't figure out.

function sleep(ms) {
   return new Promise(resolve => setTimeout(resolve, ms));
}

var xhr = new XMLHttpRequest();
xhr.open('GET', 'https://my.adp.com/myadp_prefix/payroll/v1/workers/YOUR_OID_HERE/pay-statements?adjustments=yes&numberoflastpaydates=300');
xhr.setRequestHeader("Access-Control-Allow-Origin", "*"); // CORS policy
xhr.onload = async function() {
    if (xhr.status === 200) {
        var rawData = JSON.parse(xhr.responseText);
        var lastPaydate = ""
        var consecutiveEntries = 0
        for (var index = rawData.payStatements.length - 1; index >= 0; --index) {
            var entry = rawData.payStatements[index];
            var date = entry.payDate
            // Handle multiple paystubs on the same day
            var dateSuffix = ""
            if (date === lastPaydate) {
                consecutiveEntries++
                dateSuffix = `-${consecutiveEntries}`
            } else {
                lastPaydate = date
                consecutiveEntries = 0
            }
            var year = entry.payDate.split("-")[0]
            var url = "https://my.adp.com/myadp_prefix" + entry.statementImageUri.href + "?rolecode=employee";

            var a = document.createElement('a');

            var trueIndex = (rawData.payStatements.length - index);
            if (trueIndex < 10) {
                trueIndex = "00" + trueIndex;
            } else if (trueIndex < 100) {
                trueIndex = "0" + trueIndex;
            }

            a.download = "payslip.no." + trueIndex + ".from." + entry.payDate + ".pdf";
            a.href = url;
            document.body.appendChild(a);

            await sleep(500);
            a.click();

Is there any full code can be run from the backend in 2024

This is great. Thank you to all who have developed this code. I used the version by @corymayer using Firefox 133.0 on Windows 11 without any modifications except for inserting the OID.

Hey there, can you please explain how you got the OID? Tried looking for it in responses but wasn't able to do so...would appreciate if you can run me through how you achieved that. Thank you

Login to ADP, as usual, and then go to the following URL in the same browser session: https://my.adp.com/myadp_prefix/myadpapi/core/v1/version

In the resulting JSON output look for the value labeled: 'associateoid'. Paste it into the code seen above and run it in the javascript console of your browser. I can confirm this works as of today, using Safari Version 18.6 (20621.3.11.11.3)

maybe I'm missing something, but I can't get the JSON file to show up using the above URL.
When I login and then try to use the above URL, the page reloads and shows that's I'm not logged in.
Btw, this is the URL my company is using "https://adpworld.adp.com/

@cwlls would appreciate any help here. Thank you
