How to integrate Klaviyo in automation workflow?
3 simple steps to make your Klaviyo connected with other apps in automation workflows on WEXTL. Up to 10 minutes integration set up.
STEP 2
Connect Klaviyo
When prompted, authorize access to Klaviyo in WEXTL once. Klaviyo credentials are encrypted and never shared with WEXTL. Authorization will be reused in any future API calls [3].
WEXTL wants to integrate with your Klaviyo account. Approve?
STEP 3
Build a workflow
Build your workflow with Klaviyo yourself or with WEXTL® AI Builder. Connect Klaviyo to any available integrations [5], or use HTTP node to go beyond them.
Klaviyo
How Klaviyo connects and integrates with WEXTL
Save and approve your credentials once — WEXTL® stores authorization information encrypted and reuses the authentication whenever Klaviyo app is called in workflows. That allows your marketing automations to run without your attention, per defined schedule [7]. Explore documentation [6] for a detailed list of fields that Klaviyo supports.
The following table illustrates what fields Klaviyo integration require during authorization flow inside our workflow builder [4].
Video slide demonstrates how Klaviyo is connected in WEXTL builder [4].
| Field | Type | Help |
|---|---|---|
Private API KeyRequired | password | Your Private API Key (starts with pk_). Create one under Settings > API keys. |
API RevisionRequired | text | API revision date header (format YYYY-MM-DD). Default: 2026-04-15. |
Connect Klaviyo to popular apps on WEXTL
Enter a name of the other app you want to sync with Klaviyo below. Click on selected app to explore integration options with Klaviyo. If the app you search for is not available in WEXTL yet, you can use HTTP node [10] instead to integrate it directly.
Example automation with Klaviyo integration
Select Watch Campaigns trigger from Klaviyo - this will be a starting point in your automation. Whenever event happens in Klaviyo, workflow will start [7] from Watch Campaigns node.
Search for Create Campaign Clone, connect it as the next step of integration sequence. You can use filters between Watch Campaigns and Create Campaign Clone, so only important data pass from Watch Campaigns to the next step. WEXTL gives you full control over the process of Klaviyo automation. All parts of workflow are visible on the canvas [4].
Klaviyo on WEXTL has 137 modules for combining marketing automations. Explore Klaviyo documentation for more.
Video slide demonstrates how Watch Campaigns and Create Campaign Clone [6] nodes are used in Klaviyo workflow.
Frequently asked questions
Common questions about automating Klaviyo in your workflows.
Klaviyo has 9 triggers, including "Watch All Universal Content", "Watch Bulk Import Profiles Jobs", and "Watch Campaigns", and more. Triggers are start points of the workflow, and automations may start from them.
Integration has 128 actions, including "Get Account", "Get Accounts", and "Get All Universal Content", and more. Refer to our Klaviyo Documentation for detailed inputs and outputs.
No. Most automations are built visually on the canvas by picking triggers, actions, and mapping fields. You can add custom JavaScript with Functions when advanced logic is needed — but our customers do that in rare cases [4].
Yes. Connections are authenticated per account, credentials are encrypted at rest, and you can enforce approvals and team-level access controls on any automation.
The Klaviyo integration on WEXTL runs directly on its vendor public API — every field name, authentication method, and rate limit is controlled by Klaviyo official API and covered in documentation [3]. WEXTL handles the request signing and pagination for you.
Absolutely. Where Klaviyo provides native webhooks, you can use instant triggers to eliminate polling delay. For custom webhooks, WEXTL offers Custom Webhook node, so you can start automation whenever Klaviyo or any other service sends event to webhook URL.
WEXTL is an AI-first visual canvas. The platform allows you to describe automation in plain text — and AI will wire nodes for Klaviyo inside the workflow builder [4]. You can also use built-in workflow nodes (AI Agent, Human in the Loop, Condition, Aggregate Results) in pair with Klaviyo modules to craft complex integration flows with branches, filtering, and conditional logic. There are absolutely no limits of what you can build.
