Issue store credit from Klaviyo.

Set it up in Klaviyo.

1. Get your endpoint

   In Stork, open Settings and click Manage external triggers. Copy your store's private webhook URL and secret.

2. Add a Webhook action to your flow

   In the Klaviyo flow builder, add a Webhook action and paste the URL. Add a header called X-Stork-Secret with your secret as the value.

3. Build the body

   Map email to the profile's email, set the amount, and set external_id to Klaviyo's event ID so retries never double up. Add a reason and an expiry if you like.

4. Send the customer email from Klaviyo

   Webhook credit doesn't trigger Shopify's store credit email, so tell the customer in the same Klaviyo flow. It has all the context.

{
  "email": "customer@example.com",
  "amount": "10.00",
  "currency": "AUD",
  "reason": "Review reward",
  "expires_on": "2026-12-31",
  "external_id": "{{ event_id }}"
}

Request body for Stork's external trigger

• Retry-safe. Each external_id credits at most once per store. A repeat is acknowledged and ignored, so Klaviyo's retries can't double-credit anyone.
• Creates customers. If nobody exists with that email, Stork creates the customer and credits them.
• Activity log. The last 20 requests show who was credited, how much, the reason you sent and whether it worked.
• Pause or rotate any time. Disable the endpoint while you debug, or regenerate the secret if it leaks.
