Amazing Product With Exceptional Support from the team. By using Knit we managed to speed up our development by orders of magnitude.

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 Rex + JustCall
Is there a pre-built Rex + JustCall automation?
Not yet, but Knit's Integrations Agent can build one — describe what you want and it researches Rex and JustCall's public API docs (or your own uploaded docs) and builds a working automation.
Does this require a pre-built Rex or JustCall connector?
No. The Agent works whether or not Rex or JustCall 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 Rex and JustCall help track phone communications?
Inbound calls, text messages, and missed calls handled in JustCall can automatically log activities or update lead profiles directly inside Rex.
Can I automate text message follow-ups when deal stages change?
Yes, updating a deal stage in Rex can prompt JustCall to send an automated SMS confirmation or message to the client.
