Connect FreeAgent and Klaviyo
When New Contact fires in FreeAgent, your agent runs Create Event in Klaviyo, or New Event in Klaviyo to Create Contact in FreeAgent. 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.
What do you want FreeAgent and Klaviyo to do together?
Ask the assistant
Connect your AI client
Give your AI client this address.
https://mcp.apiant.aiOne 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.
Set it up in your client

Questions
FreeAgent and Klaviyo, answered
Will a FreeAgent contact create a duplicate profile in Klaviyo?
No, the agent can look the person up with Get Profile by Email first and then use Create or Update Profile, so an existing profile is updated rather than duplicated. If no profile is found, a new one is created from the contact details.
Can billing activity in FreeAgent show up as something Klaviyo flows can use?
Yes, a new invoice or project in FreeAgent can be recorded in Klaviyo with Create Event against a metric of your choosing, or the profile can be added to a list. Flows in Klaviyo that listen to that metric or list then pick it up.
What can start an automation from FreeAgent?
Any of FreeAgent's 6 triggers in the catalog, including New Contact, New Invoice, New Project and New Bank Transaction. Describe the moment in plain language and your agent picks the right one.
What can your agent do in Klaviyo when something happens in FreeAgent?
Any of Klaviyo's 138 actions, including Create Event, Subscribe Profile, 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 FreeAgent?
Yes. When something happens in Klaviyo, your agent can act in FreeAgent too. This page covers both directions: Klaviyo's triggers and FreeAgent's actions are listed here as well.
Do I have to build a connector for FreeAgent 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 FreeAgent 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.
