- A Klaviyo account
- An e-commerce or CRM platform integrated with Klaviyo (e.g. Shopify, Salesforce, Magento, Wix, WooCommerce — see the full list)
Setup
Step 1: Get your Connectly API key
In the Connectly platform, go to Settings → General and scroll down to API Key and Webhook Secret. Click Generate API Key.
Step 2: Get your campaign destination URL and JSON body
You need the campaign’s endpoint URL and JSON payload to configure the Klaviyo webhook.- New campaign
- Existing campaign
When setting up a new campaign, select “Use the Connectly API” on the Choose Audience step and click Next.
Step 3: Create a flow in Klaviyo
Log into Klaviyo, navigate to Flows, and click Create Flow.
Step 4: Add and configure the Webhook node
Drag the Webhook node from the left sidebar and drop it into your flow at the point where you want the WhatsApp campaign to be triggered.
If this is your first time using the Webhook node, Klaviyo will prompt you to set up Multi-Factor Authentication before proceeding.
| Field | Value |
|---|---|
| Destination URL | The URL from your Connectly campaign curl snippet |
| Headers — Key | x-api-key |
| Headers — Value | Your Connectly API key |
| JSON body | The JSON payload from your Connectly campaign curl snippet |
Step 5: Map campaign variables
Your JSON body contains placeholder values that need to be replaced with Klaviyo profile properties.Expand the JSON body to see all variables
In the webhook settings panel, click the Expand icon on the JSON body section to see the full payload. Each value marked 
CHANGE_TO_* needs to be replaced.Open Preview to find Klaviyo variable names
Click the Preview button in the Settings panel header. The Preview Profile Info panel appears, showing all available profile properties. Hover over any property to reveal its Klaviyo variable name, then click to copy it.
Replace each placeholder with its Klaviyo variable
Go back to the JSON body and replace each placeholder with the corresponding Klaviyo variable. For example, replace 
"CHANGE_TO_TARGET_PHONE_NUMBER" with "{{ person.phone_number|default:'' }}" and "CHANGE_TO_VALUE" with "{{ person.first_name|default:'' }}".Step 6: Test and activate the flow
Use Trigger Preview to review flow logic
Click the Trigger node to open its settings panel, then click Preview. The Trigger Preview tool shows which profiles would enter the flow and whether they pass your filters. Use the search bar to look up a specific test user.
Set messages to Manual mode
Click on a flow message node to open its details. Change the status dropdown from Draft to Manual. In Manual mode, messages are scheduled as if live but held for your review instead of being sent automatically.
Review and approve test messages
Select the flow message and click View details in the Performance section of the right sidebar.
When a message status is updated from Manual to Live, recipients in Waiting will receive the message automatically at send time. Recipients in Needs Review will still require manual approval.
