The modern Unified API platform, built differently

Real-time, pass-through

Every request hits the source API live. No caching, no sync jobs, no stale data — just on-demand API reads/writes with native and virtual webhooks for instant updates.

Zero-storage by design

We never store end-customer data. Traffic is stateless and regionalized (US/EU/AU), reducing compliance scope and eliminating data-at-rest risk.

One API, deeply normalized

370+ integrations, 23 categories... Unified objects, endpoints, scopes, and errors—plus raw payload passthrough when you need provider-specific fields.

Custom fields & objects

Go beyond shallow schemas. We support custom fields and read/write on custom objects (e.g., Salesforce) via unified metadata APIs.

AI-ready integrations

Built for AI products: real-time streams for RAG/embeddings and Unified MCP tools that securely grant LLMs controlled integration access.

Predictable pricing, no lock-in

Transparent usage-based pricing that scales with API volume—not customers. Own your credentials and migrate anytime.

Add an Affinity integration to your application in hours

1Test drive integrations

Effortlessly test API calls, explore endpoints, and try out the Affinity 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 Affinity data.

3Start making API calls

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

Seamless Auth, no extra work

Unified.to removes the complexity of authentication and authorization so you can focus on building your product, not managing auth flows. Our pre-built UI and flexible API handle everything in the background—no extra setup required.
