OneVERIFY API Reference

Use this collection to access all our APIs. OneVERIFY provides real-time identity verification services — including NIN, phone, bank account, and face match — through a single, unified REST API.

Authentication

All endpoints except /auth/register and /auth/login require authentication. Each request must include the following headers to access the API securely:

X-API-KEY

Your unique API key. Found in your account settings after registration.

X-USER-ID

The User ID associated with your API key.

Authorization

Bearer token received after calling /auth/login. Format: Bearer <token>

Quick Start

  1. 1

    Register your account and save your API Key and User ID from the response.

  2. 2

    Call /auth/login with your email and password to receive a short-lived Bearer token.

  3. 3

    Include all three headers (X-API-KEY, X-USER-ID, Authorization) in every authenticated request.

  4. 4

    Fund your wallet and start verifying identities at scale.
