[20.0.0] - revision 2026-07-15

Added

• Custom Objects API
  • Full CRUD support across four groups of endpoints:
    • Object Types: $klaviyo->CustomObjects->createObjectType(), $klaviyo->CustomObjects->getObjectType(), $klaviyo->CustomObjects->getObjectTypes(), and $klaviyo->CustomObjects->deleteObjectType().
    • Object Schemas: $klaviyo->CustomObjects->createObjectSchema(), $klaviyo->CustomObjects->getObjectSchema(), and $klaviyo->CustomObjects->updateObjectSchema(), plus schema versions via $klaviyo->CustomObjects->getCurrentSchemaForObjectType(), $klaviyo->CustomObjects->getDraftSchemaForObjectType(), and $klaviyo->CustomObjects->getSchemaVersionsForObjectType().
    • Source Mappings: $klaviyo->CustomObjects->getSourceMapping(), $klaviyo->CustomObjects->updateSourceMapping(), $klaviyo->CustomObjects->getSourceMappingForObjectSchema(), and $klaviyo->CustomObjects->getSourceMappingIdForObjectSchema().
    • Object Records: $klaviyo->CustomObjects->getObjectRecord(), $klaviyo->CustomObjects->getRecordsForObjectType(), $klaviyo->CustomObjects->getRecordIdsForObjectType(), and $klaviyo->CustomObjects->bulkDeleteObjectRecords().
• Conversations API
  • Added support for creating conversation messages with $klaviyo->Conversations->createConversationMessage().
• Client API
  • Added $klaviyo->Client->getClientIpAllowlist() to retrieve your account's client-side IP allowlist.
• Flows API
  • Added $klaviyo->Flows->deleteFlowAction() to remove an action from a flow.

Changed

• Breaking: Conversations API
  • Conversation endpoints are now plural — e.g. $klaviyo->Profiles->getConversationForProfile() is now $klaviyo->Profiles->getConversationsForProfile() (and $klaviyo->Profiles->getConversationIdForProfile() is now $klaviyo->Profiles->getConversationIdsForProfile()), as well as the relevant relationship methods and parameters.
  • Response shapes are now lists, instead of single objects.
• Events API
  • Added a new backfill flag on $klaviyo->Events->createEvent() & $klaviyo->Events->bulkCreateEvents(), which records historical events without triggering flows.
  • $klaviyo->Events->getEvents() now returns events with unresolvable metrics by default, matching $klaviyo->Events->getEvent(). Use the new has(metric) filter to exclude them.
