Integration Guide

How the API Key and Link Actually Work

Everything you need to know after generating your API key: link structure, bearer headers, payloads, and live examples.

vrn_...

1. Your Secret API Key

Generated in your Developer Account. It begins with vrn_ and acts as your secret credential. The server never stores the raw key—only an encrypted SHA-256 hash.

/v1/{endpoint}

2. The Endpoint Link

Every Veron service has a dedicated HTTPS endpoint link (e.g. https://api.veron.io/v1/qr or /v1/pdf/to-word). All links are versioned under /v1/ for long-term stability.

Bearer Auth

3. Authorization Header

Pass your key in the standard HTTP header: Authorization: Bearer <YOUR_API_KEY>. The server authenticates your identity before executing any document or AI pipeline.

            Link Anatomy
            
Use the base link /v1 followed by the service path (e.g. /v1/qr, /v1/pdf/compress).

          

          

            Header Protocol
            
Always set Authorization: Bearer <key>. Unauthenticated requests are rejected with 401.

          

          

            File & JSON Responses
            
JSON tools return typed JSON or images. PDF/Image tools return downloadable binary attachments directly.
