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.

FAQ

Common questions about Lob + pdfFiller

Is there a pre-built Lob + pdfFiller automation?

Not yet, but Knit's Integrations Agent can build one — describe what you want and it researches Lob and pdfFiller's public API docs (or your own uploaded docs) and builds a working automation.

Does this require a pre-built Lob or pdfFiller connector?

No. The Agent works whether or not Lob or pdfFiller 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.
