Knot API is for when there's not an API! Knot gives you the power to allow your customers to instantly update their card information, passwords, and subscriptions across the merchants they use.

Great solution for fintechs

Very nice interface to switch cards on file. Like Plaid

Hello internet! We're so excited to introduce KnotAPI, the first universal merchant API...because there's not an API for it! Use KnotAPI to Change Card on File Information, Cancel Subscriptions, Change Passwords, and more. Fintechs use Knot API to grow customer spend.

We spun Knot out of Millions because our customers ran into all of these problems...so we figured, why don't we fix it for all challenger banks? For banks this means more utilization from day one, and more revenue. Want to use Knot? Get in touch or Check out our API docs!
