Introduction

Welcome to the Bridge Developer API - a comprehensive fintech payment platform for modern applications. Build powerful financial experiences with our secure, developer-friendly API.

What is Bridge API?

Bridge API enables you to integrate financial services into your applications. Accept payments, send payouts, manage wallets, and more - all through a single, unified API.

Integration journey

Bridge follows a sandbox-first onboarding model. You build and test your integration entirely against the sandbox before going live — no real money moves until you are ready.

Phase 1 — Sandbox: Contact TheBridge to receive a sandbox service_id, client_key, and secret_key. Your service will be in mode S. Use the sandbox test numbers and account values documented on each API endpoint page to trigger success and failure scenarios.

Phase 2 — Production: After completing your integration tests and KYC approval, TheBridge issues production credentials. The API host and endpoint paths are identical — only the credentials and real customer numbers change.

Important: Never use sandbox keys or sandbox test numbers in a production environment.

Quick Start

1. Get sandbox credentials: Contact TheBridge to receive your sandbox service_id, client_key, and secret_key
2. Set up authentication: Encode client_key:secret_key as Base64 and pass it in the Authorization: Basic header — see Authentication
3. Test with sandbox data: Use the test numbers and account values on each API endpoint page to validate your integration
4. Complete KYC: Submit required documents for production approval
5. Go live: Swap in your production credentials and use real customer numbers
