Integration
Connect Google Sheets to Harpoon
When something happens in Google Sheets, your agent does the next thing in Harpoon. Describe it in plain language and the automation is built, tested on every branch and kept running.
Build it
What do you want Google Sheets and Harpoon to do together?
Describe it and your agent reads both APIs, builds the automation, tests every branch and ships it. The list below is what exists today, not the limit.
Ask the assistant
You'll sign in before anything runs. What you typed comes with you.
Or work from Claude Code
Install the APIANT plugin for Claude Code and build, edit, test and read run history from your terminal. Every plan gets this, including free, and it spends no assistant credits.
