Orderandtrackverificationchecksacrossproviders
Background, identity and employment checks from providers such as Checkr, Certn and Socure through Unified.to's Verification API: list packages, create requests, read results.

One request. Every verification provider.
Swap the connection_id and the same code reads verification requests from Checkr, Certn, First Advantage or any of 24 verification integrations, in one normalized shape. Every call is live against the source API.

The modern Unified API+MCP 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.
Unified APIs, deeply normalized
1820+ integrations, 38 categories. Unified objects, endpoints, scopes, and errors—plus raw payload passthrough when you need integration-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: feed real-time data into embeddings or RAG pipelines, and let your agents perform secure write actions through MCP—all without caching or stale sync jobs.
Predictable pricing, no lock-in
Transparent usage-based pricing that scales with API volume—not customers. Own your credentials and migrate anytime.
Get integrations from backlog to production in days
1. Activate integrations
Activate the verification providers your customers use.

2. Launch integrations
List a connection's packages, then create a request with the candidate's details.

3. Authorize integrations
Embed our authorization component to let customers easily link their accounts.

Seamless authorization, no extra work
Unified removes the complexity of integration authorization so you can focus on building your product, not managing OAuth flows. Our pre-built UI and flexible API handle everything in the background—no extra setup required.
See documentationBusiness Login
Sign users in with the software their company already runs on. Redirect them to one Unified URL and get back their verified email and name. No OAuth flows to build, no tokens to store.
