We’re excited to announce the public release of our New Klaviyo APIs. These new endpoints, now all following a JSON:API standard, are more consistent and connected across the endpoints. Now, you’re enabled to programmatically access new product areas allowing you to build more powerful experience with Klaviyo. For example, utilize our new Catalogs API to create, update, or delete catalog data in an account to send more personalized messages with up-to-date product information.

 

What’s New?

The new API release contains updated and new endpoints as well as refined API features to ensure you’re able to meet your specific needs. The endpoints included in this phase will eventually replace many of Klaviyo's most commonly-used V1 & V2 endpoints. The new endpoints will provide programmatic access to the following Klaviyo resources:

  • New Endpoints: Catalogs, Flows, and Client-side
  • Updated Endpoints: Events, Metrics, Lists, Segments, Profiles, and Templates
     

Continual Releases:

Please remember that this public launch is only the beginning. Over the coming months and years, we’ll continually ship new API features based on your insight and recommendations. Some of our upcoming launches will include Campaigns and Subscriptions endpoints giving developers, for example, the ability to send SMS campaigns programmatically using the richness of Klaviyo platform features.

Hi! David. Hope doing well.

Did you know what is sos?

 

 

Hey @injamammahim,

Looks like you’re talking about SSO which stands for single sign-on. 

If you were a Klaviyo One customer and were interested in setting up SSO for security and login, you can learn how to set this up from our How to set up single sign-on for Klaviyo One users Help Center article. We highly recommend reaching out to your company’s IT department to help you set this up.

It looks like the Campaign endpoint was nixed in the new API release. 

Do you have plans to maintain that endpoint from V1-2 or will that likely be gone in the future?

Thanks

Hey @brendanuye,

Although we haven’t released a stable version of the new Campaigns endpoint yet, I can assure you our campaign’s endpoint will not be going away anytime soon. In fact, you can checkout the new Campaigns endpoint in the v2022-12-15 Beta version. 

If you haven’t already, be sure to signup to our Developer newsletter to be informed of any new endpoint releases or expansions.

David
