Connect HubSpot and Klaviyo

When Contact deleted fires in HubSpot, your agent runs Create Event in Klaviyo, or New Event in Klaviyo to Add or update contact in HubSpot. Describe the whole flow and it is built, tested on every scenario and kept running.

What the catalog holds today. Ask for anything missing and your agent reads the API documentation and adds it.

Build solutions, not workarounds.

Connect your AI client

Give your AI client this address.

https://mcp.apiant.ai

One connection does both: ask your client to act in an app once, or have it build an automation that keeps running. Any client that takes a remote MCP server. Nothing to install. Create your free account, then sign in once in your browser.

Any other MCP client

Paste the address where the client asks for a remote MCP server URL, and name the server apiant-ai where it lets you. APIANT's skills reach the client over the same connection.

HubSpot holds the sales record and Klaviyo holds the email and SMS side of the same people. Joining them means a form submission or deal stage change in HubSpot can update a Klaviyo profile, add it to a list or record an event, while new and updated Klaviyo profiles and their events flow back onto HubSpot contacts as properties and notes.

Questions

HubSpot and Klaviyo, answered

Will a Klaviyo profile be duplicated if the contact already exists there?

No, use Create or Update Profile, which upserts on email, or look the person up first with Get Profile by Email and branch on whether anything came back. The agent tests both the found and not-found paths before the flow goes live.

Can activity in Klaviyo show up on the HubSpot record?

Yes. The New Event trigger in Klaviyo can drive HubSpot actions such as Create a note engagement or Update contact properties, so an event like a placed order or an unsubscribe lands on the contact your sales team already looks at.

What can start an automation from HubSpot?

Any of HubSpot's 29 triggers in the catalog, including Contact deleted, Deal stage changed, Form submitted and New associated object. Describe the moment in plain language and your agent picks the right one.

What can your agent do in Klaviyo when something happens in HubSpot?

Any of Klaviyo's 138 actions, including Create Event, Request Profile Deletion, Create Back In Stock Subscription and Create Campaign. Your agent maps the data both ways and tests every scenario before it ships.

Can it also run from Klaviyo to HubSpot?

Yes. When something happens in Klaviyo, your agent can act in HubSpot too. This page covers both directions: Klaviyo's triggers and HubSpot's actions are listed here as well.

Do I have to build a connector for HubSpot or Klaviyo?

No. Both are in the catalog with their triggers and actions. You describe the automation; your agent builds it, tests every scenario and keeps it running.

Can my AI client use HubSpot and Klaviyo without building an automation?

Yes. With your AI client connected to APIANT, ask it to do something in either app once and it runs that action on the spot. Ask for an automation and your agent builds it, tests every scenario and keeps it running. One connection covers both.

What happens when something fails?

Your agent works that out for you. It plans the failure paths along with the happy path, then tests every scenario before it ships.

Is there a free plan?

Yes. Every plan includes the agent, including free, and building from your own AI client spends no assistant credits.
