Sandbox (Test) Production (Live)

Generate Production Keys

Step 1: Copy your Sandbox API Key from the API & Keys page.

Step 2: Create a test payment with the curl command below.

Step 3: Set up a webhook URL to receive payment notifications.

Step 4: When ready for production, generate Production keys and switch your base URL.

# Create a test payment (Sandbox) curl -X POST https://axiscorepay.com/api/v1/payments \ -H "X-API-Key: YOUR_SANDBOX_API_KEY" \ -H "Content-Type: application/json" \ -d '{ "chain": "ethereum", "currency": "USDT", "amount": "1000000", "description": "Test Order #1" }'

✅ Sandbox: sb_test_* 🔒 Production: pk_live_*

All API requests require authentication via one of two methods:

Use JWT tokens for web-based integrations and API keys for server-to-server communication. Sandbox keys start with sb_test_, production keys with pk_live_.

UPM (Universal Payment Method) — internal stablecoin pegged 1:1 to USDT. Free internal transfers. Gasless.

Instant buy/sell crypto with linked bank cards (Visa, Mastercard, Mir).

We send real-time notifications to your callback URL as HTTP POST with HMAC-SHA256 signature.

Events: payment.created, payment.pending, payment.completed, payment.expired, withdrawal.completed, withdrawal.failed

Verification: Compute HMAC-SHA256(webhook_secret, raw_body) and compare with X-Signature header. Reject if mismatch.
