ROI, Spring 2026](/wp-content/themes/knit/assets/images/g2/g2-best-roi.svg) FAQCommon questions about the iCalendar integration ------------------------------------------------ Does Knit support iCalendar out of the box?Yes — iCalendar is a live, already-built connector on Knit's Unified Calendar API, not a roadmap item. Does the iCalendar integration support both reading and writing data?Yes. It supports both reads and writes, so you can build bi-directional sync use cases — not just pull data from iCalendar, but push updates back to it. How does authentication work for iCalendar?Knit provides an embedded Auth component (white-labeling available on higher tiers) that handles iCalendar's OAuth, credential storage, and refresh — your customers authorize once through Knit, and you never touch raw credentials. What happens if iCalendar changes their API?Knit absorbs it. We maintain and update the iCalendar connector on our end, so your integration keeps working without you tracking iCalendar's changelog. Do you store iCalendar data or customer PII?No. Knit acts as a stateless passthrough — data is processed on our application server and sent directly to your webhooks, without being stored on Knit's servers. What is the pricing model, and is there a free trial?You choose the model that fits your business — pricing based on integrated accounts, or based on API call volume. Every plan includes a 30-day free trial before billing starts.
