Hi Joost,

I’ve now launched our Zettle integration with just over 4000 products but I’m having an issue.

There are a few products that won’t stay synced (approx 30 or so). There’s nothing I can determine that they have in common, it’s a mix of simple and variable products.

The strange behaviour comes when you attempt to refresh the sync by updating the product in Woo – the “View product at Paypal Zettle” link then shows but takes you to an entirely different product.

If you click Update a second time it seems to fix the problem and the Zettle link will take you to the correct product – HOWEVER the wrong product that got linked the first time around is then knocked out of sync and the same thing happens all over again with that product. It just goes back and forth, no matter what I do I can only have one or the other of these inexplicably linked products synced at any one time.

Do you have any ideas please? I’ve included the last hour of plugin logs for your review.

Hello @mattyblob

sorry to hear that you are encountering this issue, we will try to help you get to a solution for this. However, this is not a simple issue, since the issue is not constant and seems (at the moment) to have no logic, so with the information we have no we can’t advise you much. In order to get a complete overview, it would be better to have your system report (and full logs), so we can check for possible conflicting plugins.
If you prefer to not post this on a public forum, please open a private ticket on our service desk via these instructions: https://zettle.inpsyde.com/docs/request-support/
(please add the URL of this thread in the ticket as well).

Have you already tried to do the initial synchronization while all other plugins are deactivated (to exclude plugin conflicts)?

This will be a hard issue to troubleshoot with this amount of products…, I hope the amount of products does not affect the functioning of the plugin (I have never tested with such a big amount of products, so can’t be sure).

Let’s take a closer look when we have all details regarding this issue.

Kind regards,
Joost

Hi Joost,

Thanks for your speedy response as always. I did try a full re-sync with everything disabled but the problem still persisted.

As it stands at the moment I’ve been recreating the products in Woo that suffer from this problem and it seems to be working, however I’m still experiencing issues.

Firstly, updates from Woo>Zettle work flawlessly and in real time, however stock updates from Zettle>Woo are intermittently not being received.

My site is behind Sucuri firewall and I’ve been in touch with them regarding the issue to see if the culprit was there, this was their response:

“I’m sorry to hear you’ve been having this issue. What I’ve done to try and see what is going on is to review the logs for the last 3 days for entries related to your webhook folder: /wp-json/zettle/v1/webhook and here is what I am seeing:

Out of 9720 requests, 1145 were blocked by the firewall

Most of the blocks are of the type BLKUNF1 and a few as XSS016

While we cannot divulge the specific logic of these blocks, here are the corresponding entries generally describing the reasons:

https://labs.sucuri.net/signatures/waf/blkunf1-unfiltered-html-not-authorized/
https://labs.sucuri.net/signatures/waf/xss001-an-attempted-xss-cross-site-scripting-was-detected-and-blocked/

(Note we dont have a specific page for XSS016, but it is of the same general type as XSS001)

The proper procedure for getting around these blocks when they are false positives, would be, ideally, to work with Zettle to determine why these are triggering the block. However I am guessing this is unlikely to be a feasible option, and certainly an uphill struggle given you wont know specifically what is causing it, we have a couple of other options

– Allow list all of Zettles IP addresses.

– If that is not an option, the third option is to allow list the specific URL or portion of the URL”

I read in a previous support thread that Zettle doesn’t have fixed IP’s on AWS so I went with the final option and whitelisted the webhook folder, but this problem still persists.

My other issue is that when stock does sync successfully from Zettle>Woo the product becomes in stock and purchasable from the product page itself, but still appears out of stock in the catalogue and also reports as out of stock as per the Woocommerce status widget on the dashboard. I believe this is only variable products – it feels like stock updates on variations do not change the parent “In Stock” value from 0 to 1. I’ve flushed redis/varnish/WP Rocket to no avail.

I’ll submit a support ticket with site report and full logs for you to have a look at. Really hope we can get to the bottom of this, this integration has been months in the making as you know from my previous tickets!

All the best

Matt

Hi @mattyblob,
As I responded via the service desk ticket: we are working on some upgrades and have a beta/testing version available (via the service desk ticket). Adding the URL should normally work, or at least we have seen this in the past. This solution should fix this intermittent issue, but every environment for WordPress is different, so there is no 1 solution for such issues.

If you are ok with it, I would mark this thread as resolved and continue working on the service desk ticket until we get your issue fixed. Since every case is different, there will most likely not be much useful information added here for other merchants.

Kind regards,
Joost
