Sorting

Learn how to use our JSON:API sorting feature.

Sort syntax

Klaviyo’s JSON:API sorting syntax can be used across all supported endpoints in our new APIs. Please note that support for given fields is unique to each endpoint. Refer to the sort query parameter in the API reference documentation.

For endpoints that support sort operations, you can set sort to a field name in the response body such as datetime, for example. The sorting direction can be ascending (default) or descending.

The following example shows how to retrieve a sorted list of events by datetime in ascending order (oldest to newest):

curl --request GET \
     --url 'https://a.klaviyo.com/api/events/?sort=datetime' \
     --header 'Authorization: Klaviyo-API-Key your-private-api-key' \
     --header 'accept: application/json' \
     --header 'revision: 2023-07-15'

You can retrieve events by datetime in descending order (newest to oldest) by using a - prefix as shown below:

     --header 'Authorization: Klaviyo-API-Key your-private-api-key' \

Example request and response

In the following example, we make a request to get email campaigns and sort them in descending order (oldest to newest) with the created_at field:

curl --request GET \

SDK example (Node, PHP, Python, Ruby)

This example shows how to sort events by datetime with Klaviyo’s SDKs:

import { ConfigWrapper, EventsApi } from 'klaviyo-api'
const eventsApi = new EventsApi(ConfigWrapper("<Your Private Key Here>"))

const events = await eventsApi.getEvents({sort: '-datetime'})
$klaviyo->Events->getEvents(
    $fields_event=['event_properties'], 
    $fields_metric=NULL, 
    $fields_profile=NULL, 
    $filter="equals(metric_id,\"UMTLbD\")", 
    $include=NULL, 
    $page_cursor=NULL, 
    $sort='-datetime'
);
klaviyo.Events.get_events(
    fields_event=['event_properties'], 
    filter="equals(metric_id,\"aBc123\")", 
    sort='-datetime'
    )
opts = {
  sort: '-datetime'
}

response = KlaviyoAPI::Events.get_events(opts)
