Don't see your system?

Tell us what you're on and we'll build it. No build fee — you pay the same monthly rate as every other connector, and most go live in under a week.

How it works

Production-grade pipelines into Klaviyo

We handle the integration end to end, from authentication to monitoring, so your team gets clean, usable data in Klaviyo.

1

Connect

Sign in with Klaviyo over OAuth and connect your source system with API credentials, OAuth or a webhook, depending on the platform. Most setups take minutes.

2

Map

Your data lands in Klaviyo's native objects: profiles, branded events with revenue, product catalogs and consent, with a historical backfill wherever the platform supports one.

3

Run

Real-time webhooks or scheduled syncs, with retries, rate-limit handling and monitoring by our team, so data keeps flowing without anyone babysitting it.
