I am using the subscribe api and keep getting the error mentioned in subject, regardless of which format I specify.Any input appreciated, thanks… here is the payload:{ "data": { "type": "profile-subscription-bulk-create-job", "attributes": { "profiles": { "data": [ { "type": "profile", "attributes": { "subscriptions": { "email": { "marketing": { "consent": "SUBSCRIBED", "consented_at": "2025-06-18T21:54:30" } } }, "email": "ekstra@kontakt.zzy" }, "id": "01JY2CZ2H7BNTB5FK5G8BNX0JY" } ] }, "custo

Shopify Discounts - Combinable Discount Codes via Klaviyo

As you may already know, Shopify introduced combinable discount codes in June of last year, which has been a game-changer for many of us.However, I'm writing today to discuss a challenge that I and many others have faced when using Klaviyo for flows and customer rewards. As you may know, dealing with dynamic discount codes in Klaviyo can be a bit cumbersome, especially for those of us who offer automatic codes through Shopify.For example, my shop offers automatic codes for bundling promotions - Buy 2, Save 5%, Buy 4, Save 15%. Unfortunately, this causes issues with our dynamic discount codes through Klaviyo, as we have to manually enable combinations each time Klaviyo generates a new set of discount codes. (This is just not possible to keep up with)That's why I'm here today to request a new feature that would make our lives much easier - the ability to enable combinations en masse per discount through the Klaviyo dashboard. Even just the ability to automatically combine codes would be

Tiktok shop users being added to newsletter

Hi, Has anyone ever had anything like this:Profiles for tiktok shop customers have always been added to our Klaviyo profiles because of the sync with shopify, but they were added only as profiles, not to any list. Just this week, tiktok profiles are now being added to the newsletter list. It makes no sense as there is no way for them to sign up when going through tiktok shop. This is very not good as the emails bounce and affect our deliverability. Does anyone have any insights as to why this is happening and what I can do about it? Thanks,BB

Featured Reviews Carousel is unusable on mobile

Hello!Hopefully someone will know how to fix this issue, The Featured Reviews Carousel looks great on desktop but when you change it to mobile it becomes unusable. The same settings very obviously do not work for mobile and with no way to change them, it looks like a mess. The other widgets did not have this issue when changing between desktop and mobile. Would love some help with this that does not change the way it shoes up on desktopPs. I am a free user so I dont have access to their customer service options.Ideally they mobile version would just show one review that you can swipe on. While there are no changes to the desktop version showing the 4 reviews.

Solutions for using Klaviyo Reviews with browsers' privacy/security features?

We’ve recently run into an issue where Klaviyo reviews are not displaying throughout our site (on Shopify) if a browser has a built-in privacy or security measure. This has wiped out the ability to see and write reviews for customers that use Firefox, Brave and apparently some mobile devices too. That’s a meaningful (15-20%) of our traffic which is having a really negative impact on our overall CX. When I reached out to Klaviyo support asking for advice on how to handle it, or if their front end dev team was aware, I received the overplayed, generic response: “Our technicians are always working on updates to enhance your experience!” I appreciate that the CSR was just doing their job and may not have additional info — not trying to give them a hard time — but this is impacting all Klaviyo merchants as far as I can tell. Fwiw I’ve now browsed over ten different merchant sites that use Klaviyo reviews with the same result every time: no reviews displayed on these browsers/mobile. Wonder

I submitted Claspo to integration directory several times, but no response from Klaviyo team

I need help with submission of my app to Klaviyo Integration Directory. The thing is that we connected Claspo years ago (our listing page). Since that Klaviyo became one of most popular destination points. Especially when we launched our Shopify App in 2024th. I submitted listing application several times in 2024th, then in 2025, but got no response. Please, help trouble shoot it.

handling log in / log out within a SPA

How do we leverage the front-end Identify API to handle when users log in and log out within a Single-Page Application (Angular) without refreshing the page? It seems that the 'identify' method is having issues being recognized properly when called multiple times per page load.

Custom Property value upload across multiple csv's

I am migrating our database and I’ve got multiple csv files prepared of different lists e.g. they have visited our bar, and they have purchased 2 different products from our online store. For this example they would feature on 3 lists, one for each product and one for the bar - if I have a custom property column in the two product csv’s which are both titled ‘Product Purchase’ but each has a different value under it in the different csv’s will both of the values be added to that customers one profile? Or will one overwrite the other because the title of the customer property is the same? I don’t want to add it as a ‘list’ because the data isn’t within one csv, and I don’t know how to compile the data into one csv in the particular format Klaviyo needs it {“x”, “y”] without it being manual and we’ve got thousands of orders we need to port over. I hope that makes sense!

API Enhancement Request – Include Email Profile Count in List API Response

Hi Klaviyo Team,I’ve been reviewing the current Developer API documentation and noticed that the /lists/{list_id}/profilesendpoint does not return the total count of email profiles associated with the list.For example, my list with ID VAZemD contains 10 profiles. However, when calling the following API:curl --location 'https://a.klaviyo.com/api/lists/VAZemD/profiles' \--header 'Authorization: Klaviyo-API-Key xyzkey' \--header 'Accept: application/json' \--header 'Revision: 2025-01-15'The response does not include the profile count.This is a standard feature provided by other platforms such as Mailchimp, Google Contacts, and HubSpot. Having the profile count readily available is crucial when building integrations, reporting usage, or simply understanding list sizes at a glance.While it’s technically possible to create a segment and then query the count, this adds unnecessary overhead—multiple steps for what should be a simple, single-call operation. End users expect quick access to suc

Why did my Klaviyo flow fail to send an email after a time delay? (first emai in the flow worked as expected)

Expected outcome:As a Flow user, I expect that I can set a specific Email action that is _immediately sequential to a Time Delay_ to "Live" from previous value of "Draft" hours before the Time delay (configured to propagate the contact profile at 9:15am local time for M/Tu/Thu/Fri) propagates the existing contact profiles to that same successive Email action, and that users would receive that email on Monday after a 3-day delay from propagating there from the previous successful email action on Thursday afternoon Actual outcome: As a Flow user, I had changed the Email action from "draft" to "Live" on Monday morning a little after 12am (and well before the expected Time Delay criteria of 9:15am for any contact profiles local time), and the preceding Time Delay utility (set to proceed profiles to the next Action at 9:15am recipient's local time on M/Tu/Thu/F) that profiles had already entered into on the previous Thursday afternoon after all successfully receiving the first Email in this

Matchrate in Google Ads very low

I have synchronized Klaviyo audiences with Google Ads for better targeting, but I see that the match rate is only 10-15%. Does anyone have experiences with this and a solution to increase the match rate?
