How do I connect Klaviyo?

Add the Klaviyo piece to a flow, then authenticate with API key or OAuth 2.0. Once connected, its 2 triggers and 11 actions are available anywhere in the builder.

What can I automate with Klaviyo?

"New Profile" can start a flow that runs "Create Profile", and you can chain Klaviyo together with any of 760+ other apps and AI steps in between.

Can I self-host the Klaviyo integration?

Yes. Activepieces is fully self-hostable, so you can run the Klaviyo piece on your own infrastructure with your connections and your data staying in your environment.

Can my AI agent use Klaviyo as a tool?

Yes. Every piece you connect can be exposed over one Activepieces MCP server, so Claude, Cursor, Windsurf or any MCP client can call Klaviyo actions as tools.
