-
Breaking Subscribe API Synchronous Validation Improved
- To provide better feedback for handling SMS subscriptions, we’ve added improved validation behavior to
$klaviyo->Profiles->subscribeProfiles
method. In prior revisions, such requests may appear as 202s but will fail to update SMS consent. To handle this issue, 400 validation errors are returned for the following cases- If a profile is subscribed to SMS marketing and age-gating is enabled but age_gated_date_of_birth is not provided, or the DOB does not meet the region's requirements.
- If the account does not have a sending number in the phone number’s region.
- If the phone number is in a region not supported by Klaviyo.
- If consented_at is set and the list or global setting is double opt-in.
- To provide better feedback for handling SMS subscriptions, we’ve added improved validation behavior to
- Patched a bug due to incorrect handling of page_cursor
- Patched a bug due to colliding enum variable names
- Optional
$user_agent_suffix
param to client instantiation- example usage:
$klaviyo = new KlaviyoAPI( 'YOUR_API_KEY', $num_retries = 3, $wait_seconds = 3, $guzzle_options = [], $user_agent_suffix = "/YOUR_APP_NAME");
-
New
Reporting
allows you to request campaign and flow performance data that you can view in the Klaviyo UI. -
campaignValuesQuery
- Request campaign analytics data, for example, a campaign performance report on the open rate over the past 30 days.
-
flowValuesQuery
- Request flow analytics data, for example, a flow performance report on the revenue per recipient value over the past 3 months.
-
flowSeriesQuery
- Fetch flow series data for a specific interval and timeframe, for example, a flow performance report on weekly click rates over the past 12 months.
-
New
Profiles
endpoint allows you to create or update a profile with a set of profile attributes.createOrUpdateProfile
- This endpoint operates synchronously and offers an upsert pattern similar to the v1/v2 Identify API.
-
Removed the $attribution field from event_properties in getEvent and getEvents (breaking change).
- To include this data in your request, add include=attributions to your request.
We have added the following endpoints to enable bulk profile imports:
Profiles->spawnBulkProfileImportJob
Profiles->getBulkProfileImportJob
Profiles->getBulkProfileImportJobs
Profiles->getBulkProfileImportJobLists
Profiles->getBulkProfileImportJobProfiles
Profiles->getBulkProfileImportJobImportErrors
Profiles->getBulkProfileImportJobRelationshipsProfiles
Profiles->getBulkProfileImportJobRelationshipsLists
When using Profiles->subscribeProfiles
, the relationships
field of the payload is now optional (see Profiles->subscribeProfiles reference for details).
Support for returning list suppressions via the /profiles endpoint
We now support filtering on list suppression with the get profiles endpoint, which brings us to parity with v2 list suppression endpoint that was the previously recommended solution.
Rules for suppression filtering:
- You may not mix-and-match list and global filters
- You may only specify a single date filter
- You may or may not specify a reason
- You must specify a list_id to filter on any list suppression properties
Examples:
- To return profiles who were suppressed after a certain date:
$filter="greater-than(subscriptions.email.marketing.suppression.timestamp,2023-03-01T01:00:00Z)"
- To return profiles who were suppressed from a specific list after a certain date:
$filter="greater-than(subscriptions.email.marketing.list_suppressions.timestamp,2023-03-01T01:00:00Z),equals(subscriptions.email.marketing.list_suppressions.list_id,\"LIST_ID\")"
- To return all profiles who were suppressed for a specific reason after a certain date:
$filter="greater-than(subscriptions.email.marketing.suppression.timestamp,2023-03-01T01:00:00Z),equals(subscriptions.email.marketing.suppression.reason,\"user_suppressed\")"
Optionally retrieve subscription status on Get List Profiles, Get Segment Profiles, Get Event Profile
Now you can retrieve subscription status on any endpoint that returns profiles, including Get List Profiles, Get Segment Profiles and Get Event Profile. Use $additional_fields_profile="subscriptions"
on these endpoints to include subscription information.
The subscription object is no longer returned by default with get profile(s) requests. However, it can be included by adding the $additional_fields_profile="subscriptions"
to the request. This change will allow us to provide a more performant experience when making requests to Get Profiles without including the subscriptions object.
In the interest of providing more clarity and information on the subscription object, we have renamed several fields, and added several as well. This will provide more context on a contact's subscriptions and consent, as well as boolean fields to see who you can or cannot message.
For SMSMarketing:
timestamp
is nowconsent_timestamp
last_updated
is a new field that mirrorsconsent_timestamp
can_receive_sms_marketing
is a new field which isTrue
if the profile is consented for SMS
For EmailMarketing:
timestamp
is nowconsent_timestamp
can_receive_email_marketing
is True if the profile does not have a global suppressionsuppressions
is nowsuppression
last_updated
is a new field that is the most recent of all the dates on the object
Images
API- We now support the following operations to work with images:
getImage
getImages
updateImage
uploadImageFromFile
uploadImageFromUrl
- We now support the following operations to work with images:
Coupons
API- We now support CRUD operations for both Coupons and Coupon Codes
- Check out Coupons API guide for more information.
- New profile merge endpoint:
Profiles->mergeProfiles
- Additional filtering/sorting option for getting profiles from
Lists
andSegments
:joined_group_at
- Increased the maximum page size limit for
Lists->getListRelationshipsProfiles
andSegments->getSegmentRelationshipsProfiles
to 1000
- Flow Message Templates
- You can now retrieve the templates associated with flow messages using
Flows->getFlowMessageTemplate()
orFlows->getFlowMessageRelationshipsTemplate()
. You’re also able to include the template HTML for a flow message usingFlows->getFlowMessage($id, $include=['template'])
. - Create or Update Push Tokens
- We have added an endpoint to create or update push tokens,
Profiles->createPushToken()
. This endpoint can be used to migrate profiles and their push tokens from another platform to Klaviyo. If you’re looking to register push tokens from users’ devices, please use our mobile SDKs.
- Back-In-stock APIs
- We have added support for subscribing profiles to back-in-stock notifications, for both email and SMS, using the new createBackInStockSubscription endpoint.
- New functionality to Campaigns API
- CRUD support for SMS campaigns is now available
- You can now also retrieve all messages for a campaign to determine performance data on campaigns where you're running A/B tests
- To support this functionality, we introduced a relationship between campaigns and campaign messages, and between campaign messages and templates
- Relationship Standardization
- We are making a number of changes across endpoints to standardize how we handle relationships in our APIs and leverage consistently typed objects across endpoints. For example, you can create a profile in our APIs in the same shape, regardless of whether you're calling the profiles endpoint or the events endpoint.
- The changes include:
- Updating 1:1 relationships to use singular tense and return an object (instead of plural and return an array)
- example: for getFlowAction, if you want to use the
include
param, you would setinclude=
to"flow"
(instead of"flows"
); the response will be an object (previously an array)
- example: for getFlowAction, if you want to use the
- Moving related object IDs from the attributes payload to relationships
- example: The format for the body of create_tag has changed, with
tag_group_id
previously atdata.attributes.tag_group_id
being removed and replaced by adata
object containingtype
+id
and located atdata.relationships.tag-group.data
.
- example: The format for the body of create_tag has changed, with
- Specifying a relationship between two Klaviyo objects to allow for improved consistency and greater interoperability across endpoints
- example: for createEvent, you can now create/update a profile for an event in the same way you would when using the profiles API directly
- Updating 1:1 relationships to use singular tense and return an object (instead of plural and return an array)
- NOTE: The examples for the above relationship changes are illustrative, not comprehensive. For a complete list of ALL the endpoints that have changed and exactly how, please refer to our latest API Changelog
- For getCampaigns endpoint,
filter
param is now required, to, at minimum, filter onmessages.channel
- We removed the
company_id
from the response for getTemplate and getTemplates. If you need to obtain the company ID / public API key for an account, please use the Accounts API.
- Accounts API is now available, this will allow you to access information about the Klaviyo account associated with your API key.
getAccounts
getAccount
Note: You will need to generate a new API key with either the Accounts
scope enabled or Full Access
to use these endpoints.
- All
client
endpointscreateClientEvent
createClientProfile
createClientSubscription
- Fixed order of params, and added
page_size
, so some calls may need to be updated.
- Relationship endpoints that were previously grouped together are now split into related-resource-specific endpoints. This means that all relationship endpoints have new function names.
- Profiles API can now return predictive analytics when calling
getProfile
andgetProfiles
, by passing in$additional_fields_profile=["predictive_analytics"]
.
- To migrate to this latest version, all calls to relationship endpoints need to be updated, as in the following example:
getCampaignRelationships($id, "tags")
will becomegetCampaignRelationshipsTags($id)
.
- Because PHP is sensitive to the ordering of optional args, this is a breaking change to all
getProfile
andgetProfiles
calls that use optional args. Please refer togetProfile
andgetProfiles
in the README for more details on ordering.- Specifically, because params are passed in alphabetical order, even if you do not intend to use this new param, you will need to shift over the params by one by passing in
$additional_fields_profile=NULL
.
- Specifically, because params are passed in alphabetical order, even if you do not intend to use this new param, you will need to shift over the params by one by passing in
