Integration
Connect Close and Harpoon
When New Contact in Contact Smart View fires in Close, your agent runs Create Contact in Harpoon, or New Client in Harpoon to Add Address to Lead in Close. 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 Close and Harpoon 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.

Questions
Close and Harpoon, answered
What can start an automation from Close?
Any of Close's 3 triggers in the catalog, including New Contact in Contact Smart View, New Lead in Smart View and New Note. Describe the moment in plain language and your agent picks the right one.
What can your agent do in Harpoon when something happens in Close?
Any of Harpoon's 46 actions, including Create Contact, Create Expense, Create Expense Category and Create Project. Your agent maps the data both ways and tests every scenario before it ships.
Can it also run from Harpoon to Close?
Yes. When something happens in Harpoon, your agent can act in Close too. This page covers both directions: Harpoon's triggers and Close's actions are listed here as well.
Do I have to build a connector for Close or Harpoon?
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 Close and Harpoon 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.
