What shipping integrations with Knit actually gets you
Close More Deals
Turn “do you integrate with X?” into a yes on every call — native integrations remove one of the most common blockers in enterprise deals.
Turn Integrations into ARR
Package integrations as a product feature, not a one-off services engagement, and convert one-time revenue into recurring ARR.
Save Engineering Hours
Stop burning sprints on one-off API integrations. Ship what used to take a quarter in days, and keep engineers on your core product.
Skip the Integrations Team
No need to hire and maintain an in-house team just to keep connectors alive through every customer go-live.
Faster Time to Value
Customers go live faster when integrations are ready on day one, instead of a multi-week onboarding project.
Cut the System Integrator Bill
Stop pointing customers to expensive SI partners just to connect their stack — it’s built into your product.
Every app your customers ask for — reads and writes
180 apps across 13 categories, all reachable through one schema. Missing something? Most new connectors ship in days, not months, once we have access to the API docs.

What makes it a Unified API, not just an API
Embedded Authentication
Your users authorize the integration from within your product using a fully white-labeled, customizable auth component — embed it with a few lines of code.
Custom Field Mapping
During authentication, your users can map their own custom fields to the fields your product needs — integrating with non-standard, customized systems becomes routine, not a rebuild.
DIY Scope Management
Users control exactly what access they grant your product, toggling field- and record-level permissions right at the point of authorization.
Real-Time Data
Once authorized, Knit delivers fresh data to your webhooks on a schedule you set — or make on-demand API calls to the source for reads and writes.
Integrations Observability
Every live integration is visible in a dashboard your team can actually use — logs, issues, and controls to pause or debug a sync without touching code.
Security architecture buyers actually ask about
Not bolted on after the fact — Knit was built stateless from day one.
Stateless Integrations
Unified syncs without storing your customers’ data — a pure passthrough, processed on our application server and sent directly to your webhooks.
Advanced Scope Control
Column and row-level scope control at both the developer and end-user level, so customers know exactly what’s authorized.
Embedded, White-Labeled Auth
An embedded Auth component handles OAuth, credential storage, and refresh — your customers authorize once, and you never touch raw credentials. White-labeling available on higher tiers.
Data Residency
Choose where data is processed — US, EU, or India — to match your own compliance footprint.
One schema. Real code, not docs to decode.
{
"success": true,
"data": {
"contacts": [
{
"info": {
"id": "101",
"firstName": "Kendall",
"lastName": "Roy",
"jobTitle": "CEO",
"owner": { "email": "sales@gojo.com" },
"updatedAt": "2023-05-23T12:04:54Z"
},
"emails": [
{ "type": "NOT_SPECIFIED", "email": "kendall@waystar.com" }
]
}
],
"nextPageToken": "String"
}
}The same normalized schema works for writes — POST /ats.application.create pushes a candidate into an ATS with the same request shape. Browse the full API reference →

Trusted by global SaaS teams shipping integrations
Amazing Product With Exceptional Support from the team. By using Knit we managed to speed up our development by orders of magnitude.
A brilliant tool to let you seamlessly integrate with many different systems. It is very easy to integrate with and customer support is next level.
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.
Easy to integrate. Knit's dashboard is intuitive for setting up and testing integrations, and the sandbox is extremely useful during development.

Zero-storage and real-time — not the industry default
Knit adds a natural-language Integrations Agent and hosted MCP servers on top of the Unified API — not just the API alone.
Typical Unified APIs
- Data often cached or stored server-side
- Polling-based sync as the default
- Fixed field mapping, limited customization
Knit
- Zero-storage, stateless passthrough
- Webhook-first, near real-time by default
- Custom fields and non-standard data models supported
Simple, predictable pricing
Choose the pricing model that fits your business — pay based on integrated accounts, or pay based on API call volume.
Common questions about the Unified API
Which apps and systems do you currently support?
180 apps across 13 categories — HRIS, ATS, CRM, Accounting, Calendar, Communication, and more. Browse the full catalog on our Integrations page.
Does the API support 2-way sync (writing data back to the source)?
Yes. The Unified API supports both reads and writes, so you can build bi-directional sync use cases — not just pull data, but push updates back to the source app.
How does authentication / OAuth flow work?
Knit provides an embedded Auth component (with white-labeling available on higher tiers) that handles OAuth, credential storage, and refresh — your customers authorize once through Knit, and you never touch raw credentials.
Do you store 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 timeline for building a new connector?
Typically days, not months — thanks to the same AI-based tooling that lets us maintain 180 existing connectors.
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.
