The modern Unified API+MCP platform, built differently

Real-time, pass-through

Every request hits the source API live. No caching or sync jobs: reads and writes go to the source API, and native and virtual webhooks report changes on supported integrations.

No customer records at rest

No customer records at rest; connection credentials and operational metadata are encrypted at rest. Each workspace runs in one region: US on every plan, EU or AU on Pro and Scale.

Common objects across every category

Unified objects, endpoints, scopes and errors across every category, plus raw payloads when you need vendor-specific fields.

Custom fields & objects

Read and write custom fields through the Metadata API; reach custom objects through raw fields and the Passthrough API.

AI-ready integrations

Built for AI products: Unified MCP gives LLMs scoped access to integration tools, with options to limit permissions and hide sensitive fields.

Predictable pricing, no lock-in

Usage-based pricing that scales with API volume, not with the number of customers you connect. Own your credentials and export them anytime; tokens issued to your own OAuth app keep refreshing after you leave.

Add a QuickBooks Desktop integration to your application in hours

1Test drive integrations

Effortlessly test API calls, explore endpoints, and try out the QuickBooks Desktop integration using synthetic data in our Sandbox environment.

2Authorize connections

Drop in our Authorization component with a single line of code. Your users can then connect and grant access to their QuickBooks Desktop data.

3Start making API calls

Use the Connection ID to interact with QuickBooks Desktop via our unified API. We handle maintenance and updates so you can focus on your product.

Authorization handled for you

A pre-built authorization component and API handle each vendor's sign-in, so your code works with a connection ID.
