Integration
Connect Harpoon and Whop
When New Client fires in Harpoon, your agent runs Create Invoice in Whop, or Dispute Updated in Whop to Add Invoice in Harpoon. 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.
