Performance Management

One request. Every performance management platform.

Swap the connection_id and the same code reads reviews from Lattice, 15Five, Culture Amp or any of 10 performance management integrations, in one normalized shape. Every call is live against the source API.

curl --get \
  'https://api.unified.to/performance/{connection_id}/review' \
  --data 'limit=1' \
  --header "authorization: bearer $UNIFIED_API_KEY"

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.
