Amazing Product With Exceptional Support from the team. By using Knit we managed to speed up our development by orders of magnitude.
A brilliant tool to let you seamlessly integrate with many different systems. It is very easy to integrate with and customer support is next level.
Seamless integration experience. Well-documented, self-explanatory APIs, and excellent service and support.
Easy to integrate. Knit's dashboard is intuitive for setting up and testing integrations, and the sandbox is extremely useful during development.
Knit shipped a brand-new Timesheet API in a week and handed us a ready-to-use NetSuite sandbox. That velocity is priceless when you're running payroll in 40+ countries.

Common questions about Mainstack + Circle
Is there a pre-built Mainstack + Circle automation?
Not yet, but Knit's Integrations Agent can build one — describe what you want and it researches Mainstack and Circle's public API docs (or your own uploaded docs) and builds a working automation.
Does this require a pre-built Mainstack or Circle connector?
No. The Agent works whether or not Mainstack or Circle already has a pre-built connector in Knit's catalog — it researches the real API surface either way.
How long does it take to build?
Minutes to build a first working version, not weeks — you test it against real data before it goes anywhere near production.
How does connecting Mainstack to Circle benefit store managers?
It posts instant notifications into key chat channels in Circle whenever sales milestones or abandoned carts occur in Mainstack.
Can team messages in Circle initiate custom updates in Mainstack?
Yes, specific chat messages posted in Circle can invoke custom API calls in Mainstack to automate store administrative tasks directly from team chat.
