  1. In Mailing list → Webhooks, add a webhook and choose the Klaviyo adapter.
  2. Paste the HTTPS URL Klaviyo issues for bulk profile subscription jobs (see Klaviyo’s API docs for the current endpoint and headers).
  3. Provide any required private keys or headers Klaviyo expects—fanmigo stores configuration securely per webhook.
  4. Run Test and confirm the job is accepted, then subscribe a test email on your link page.
