Technical Implementation

Authentication

All API requests require authentication using a JWT Bearer token. Authentication follows these steps:

Obtain API Credentials: Register with Surepass to receive your API key.

Generate JWT Token: Use your API key to generate a JWT token.

Include in Requests: Add the token to the Authorization header as Bearer TOKEN.

Different authentication tokens are used for sandbox and production environments:

Sandbox: https://sandbox.surepass.io

Production: https://kyc-api.surepass.io

Implement proper error handling to manage authentication failures gracefully

Rotate JWT tokens periodically to minimize security risks

User Experience Guidelines

Use high-quality brand images with transparent backgrounds for best results

Ensure brand images are optimized for both mobile and desktop viewing

Test the branding appearance across different document types
