Integration
Connect Google Docs and Harpoon
When Document Structure Changed fires in Google Docs, your agent runs Add Invoice in Harpoon, or New Client in Harpoon to Create Document in Google Docs. 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.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
Google Docs and Harpoon, answered
What can start an automation from Google Docs?
Any of Google Docs's 10 triggers in the catalog, including Document Structure Changed, Document Updated, New Document Added and New Document Created. Describe the moment in plain language and your agent picks the right one.
What can your agent do in Harpoon when something happens in Google Docs?
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 Google Docs?
Yes. When something happens in Harpoon, your agent can act in Google Docs too. This page covers both directions: Harpoon's triggers and Google Docs's actions are listed here as well.
Do I have to build a connector for Google Docs 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 Google Docs 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.
