Getting Started

🚀 Welcome to HashDT API's​

Welcome to HashDT — your all-in-one platform for digital payments, wallet management, and seamless API integrations.

This guide is designed to help you integrate HashDT APIs quickly and confidently, whether you're building a sandbox app or preparing for production.

🔑 Key Points Before You Start​

  • Always collect and secure your API keys. Never expose your secret keys in frontend code.
  • The API secret key is delivered securely to your email by HashDT.
  • Use a unique x-request-id for each API request to ensure idempotency and reliable tracking.

🧪 Use the Sandbox Environment​

HashDT provides a fully isolated sandbox for safe testing of your integrations.

  • Sandbox credentials have been shared via email to your team.
  • Always use sandbox-specific API keys when testing.
  • No real financial transactions are processed in the sandbox.
  • Simulate different scenarios to test your app without impacting real users.

🌐 Sandbox Base URL : https://api.sandbox.zoqq.com — Used for development and testing. All transactions in this environment are simulated and safe.

💡 Tip: Treat the sandbox as a playground — experiment with all API endpoints and verify your logic.
