Our Platform
Knot is a merchant connectivity platform that securely connects your application to your customers’ online merchant accounts.
With Knot, your app connects to your customers’ merchant accounts. From there it can put your card on file, shop on their behalf, and read and write their account data. And that is just the start.

Built for rapid integration
Knot fits seamlessly into your existing stack, letting you launch new capabilities in minutes with minimal code and no infrastructure changes.
Don’t Compromise. Choose Knot
Leading companies choose us because performance and security shouldn’t be a tradeoff.
API-native architecture
Knot connects directly via merchant APIs. It does not use browser automation or screen scraping, so integrations are durable and scalable and do not break when a UI changes.
Persistent connections
Users authenticate once. Knot securely maintains the merchant connection, enabling server-side card updates and background data retrieval without asking them to log in again.
Broadest merchant coverage
The largest and fastest-growing network of supported merchants. It covers the services your customers use most, from streaming to food delivery to e-commerce.
Highest conversion rates
Built over 4+ years and with thousands of edge cases handled, continuously optimized for high conversion and frictionless authentication across keychains and SSO logins.
Enterprise-grade security
PCI DSS and SOC 2 compliant. There are no third-party runtime dependencies, and everything is secured with mTLS and strict ingress and egress controls.
Multi-product platform
One integration unlocks a complete merchant connectivity platform. As more accounts are linked, the value of the platform grows and it supports more products over time.
Powering banks, fintechs & beyond
Top of Wallet
Automatically update card-on-file at (almost) every merchant so your card becomes the default payment method, lifting transaction frequency and interchange revenue from day one.
Subscription Management
Let users manage, pause, cancel and upgrade their subscriptions without leaving your app, turning a support burden into upgrade-driven card spend.
Dispute Deflection
Give cardholders itemized, SKU-level proof of what they bought upfront, clearing up vague transaction descriptions and stopping friendly fraud before it becomes a chargeback.
