Klaviyo

Verified integration

From Klaviyo Flows you bring contacts into SendApp and tag them, via Webhook.

Your Webhook URL
https://app.sendapp.ai/api/integrations/webhook/YOUR_ACCOUNT_TOKEN?source=klaviyo
Log in to get the real webhook URL for your account.

How it works

When a Klaviyo Flow sends an event, we create or update the contact in SendApp (name, phone, email from the payload) and tag it. We don't send messages on your behalf: you contact the leads whenever you want with a campaign or via API.

Step-by-step setup

  1. Copy your Webhook URL from the box above (select the account first).
  2. Log in to Klaviyo and create or edit a Flow with a trigger that has the profile (so the profile contains email and phone_number):
    • List/Segment
    • Metric
  3. Add an Action of type Webhook with POST method and paste the URL.
  4. Save.

General rule: choose events that include customer data (name, phone or email): without a phone or email the contact is not created.

What happens next

The contacts coming from Klaviyo are created and tagged (klaviyo) in SendApp. Reach them with a campaign filtering by that tag, or through the API.

Verify

Trigger a test event from the Flow on Klaviyo and check that the contact appears in SendApp. If the phone or email is missing, the contact is not created.
