# Certn API Integration on Truto



**Category:** Background Verification  
**Status:** Built on request

## How it works

1. **Link your customer's Certn account.** Use Truto's frontend SDK; we handle every OAuth and API key flow so you don't need to create the OAuth app.
2. **Authentication is automatic.** Truto refreshes tokens, stores credentials securely, and injects them into every API request.
3. **Call Truto's API to reach Certn.** The Proxy API is a 1-to-1 mapping of the Certn API.
4. **Get a unified response format.** Every response uses a single shape, with cursor-based pagination and data in the `result` field.
