ROI, Spring 2026](/wp-content/themes/knit/assets/images/g2/g2-best-roi.svg) FAQCommon questions about the fastbill automation ---------------------------------------------- Is there a pre-built fastbill automation?Not yet — fastbill isn't in Knit's Unified API or MCP Servers catalog today, so there's no pre-built connector for it either. The Integrations Agent can build the real automation (and the connector powering it) on demand instead of you waiting on our roadmap. How does the Agent actually build the fastbill connector?It researches fastbill's real public API documentation — authentication, endpoints, data schema — and writes a working connector against that real surface. You can also upload your own docs if fastbill's aren't public. How long does it take?Minutes to build a first working version, not weeks — you test it against real fastbill data before it goes anywhere near production. What happens after the Agent builds it?You own it. It runs the same way any Knit-built connector does — you are not left maintaining hand-rolled integration code yourself. Could fastbill become a real pre-built connector later?Yes — as apps get built and used through the Agent, the highest-demand ones are natural candidates to join the pre-built Unified API/MCP Servers catalog directly.
