The 3Pay API gives you a simple way to accept stablecoin payments, check their status, and request withdrawals. This section walks you through the basics you need to know before making your first call.
What You’ll Learn Here
- How to connect to the correct environment (Sandbox for testing, Production for live transactions).
- How to authenticate using your API Key and Secret.
- The difference between payments (inbound funds) and withdrawals (outbound funds).
- How to receive real-time updates using webhooks.
- Where to find supported assets and payment rails.
What You’ll Need
- A 3Pay account and access to the Dashboard.
- Your API Key and API Secret (one set for Sandbox, another for Production).
- A server endpoint (
callbackUrl) to receive webhook events.
Once you complete this section, you’ll be ready to create your first transaction in the Sandbox environment.
