About Knot API
What Knot API does
Knot API provides a single interface to connect your app with dozens of services like Slack, GitHub, and Stripe. Instead of writing separate code for each provider, you use one API, one authentication flow, and one data format. It handles OAuth, webhooks, token refresh, and rate limiting automatically.
Who it’s for
Knot API is built for developers and startups shipping multi-integration products quickly. It’s ideal for teams tired of maintaining custom connectors and needing to add merchant features like card updates or account linking in days, not months. It’s not suited for projects requiring only one or two simple integrations, or for teams with extremely niche, unsupported third-party services.
Real use cases
Fintech apps use Knot to let users update card details across merchants in a few clicks. SaaS platforms embed “connect your account” buttons that authenticate with Stripe or Slack in minutes. Engineering teams reduce maintenance overhead by centralizing OAuth and webhook routing into a single endpoint.
