Official Python SDK for BlaziumPay - Production-ready crypto payment infrastructure

BlaziumPay Python SDK

Official Python SDK for BlaziumPay - Production-ready crypto payment infrastructure for TON, Solana, and Bitcoin.

Installation

pip install blaziumpay

Quick Start

from blaziumpay import BlaziumPayClient, BlaziumConfig, BlaziumEnvironment

# Initialize client
config = BlaziumConfig(
    apiKey="your-api-key",
    environment=BlaziumEnvironment.PRODUCTION,
    webhookSecret="your-webhook-secret"  # Optional, for webhook verification
)

client = BlaziumPayClient(config)

# Create a payment
from blaziumpay import CreatePaymentParams

payment = client.create_payment(
    CreatePaymentParams(
        amount=10.00,
        currency="USD",
        description="Premium subscription",
        metadata={"userId": "12345"},
        rewardAmount=1,  # Optional metadata: 1 premium subscription
        rewardCurrency="premium"  # Optional metadata: Premium access
    )
)

print(f"Payment created: {payment.checkoutUrl}")

# Wait for payment confirmation
confirmed_payment = client.wait_for_payment(payment.id)
print(f"Payment confirmed: {confirmed_payment.txHash}")

# Note: You must implement your own webhook handler to grant
# premium features when payment is confirmed. See Webhook Handling section.

Webhook Handling

Important: BlaziumPay does NOT automatically grant rewards or premium features. You must implement your own logic in webhook handlers to grant rewards, unlock features, or perform any other actions when a payment is confirmed.

Webhook Verification: Only verified webhooks receive events from BlaziumPay. You must verify your webhook endpoint in the dashboard before it will receive any events. Unverified webhooks will not receive any webhook events.

from flask import Flask, request
from blaziumpay import BlaziumPayClient, BlaziumConfig, WebhookEventType

app = Flask(__name__)

client = BlaziumPayClient(
    BlaziumConfig(
        apiKey="your-api-key",
        webhookSecret="your-webhook-secret"  # Required for webhook verification
    )
)

@app.route("/webhooks/blazium", methods=["POST"])
def handle_webhook():
    signature = request.headers.get("X-Blazium-Signature")
    raw_body = request.get_data(as_text=True)
    
    # Verify and parse webhook
    # Note: If webhookSecret is not configured, this will raise a ValidationError
    # with a helpful message explaining that webhooks must be verified first
    webhook = client.parse_webhook(raw_body, signature)
    
    if webhook.event == WebhookEventType.PAYMENT_CONFIRMED:
        payment = webhook.payment
        user_id = payment.metadata["userId"]
        
        # YOUR CUSTOM LOGIC HERE - You decide what happens:
        
        # Example: Grant premium features
        if payment.rewardCurrency == "premium":
            database.users.update(user_id, {"is_premium": True})
        
        # Example: Add in-game currency
        if payment.rewardCurrency == "coins":
            database.users.increment_coins(user_id, payment.rewardAmount)
        
        # You have full control - implement whatever logic you need!
    
    return {"received": True}, 200

Webhook Verification Process:

1. Create a webhook endpoint in the dashboard
2. Verify the endpoint ownership (BlaziumPay will send a challenge token)
3. Save the webhook secret securely (shown only once after verification)
4. Configure the secret in your SDK client
5. Only verified webhooks receive events - unverified webhooks are ignored by BlaziumPay

API Reference

Client Methods

create_payment(params, options=None)

Create a new payment. The rewardAmount and rewardCurrency fields are optional metadata for your reference. BlaziumPay does not automatically grant rewards - you must implement your own logic in webhook handlers.

payment = client.create_payment(
    CreatePaymentParams(
        amount=10.00,
        currency="USD",
        description="Product purchase",
        redirectUrl="https://example.com/success",
        cancelUrl="https://example.com/cancel",
        expiresIn=3600,  # 1 hour
        rewardAmount=1,  # Optional metadata: 1 premium subscription
        rewardCurrency="premium",  # Optional metadata: Premium access
        metadata={"orderId": "123", "userId": "user_456"}
    ),
    CreatePaymentOptions(idempotencyKey="unique-key-123")
)

# Note: rewardAmount is stored as metadata, but you must implement
# your own webhook handler to grant rewards when payment is confirmed

get_payment(paymentId)

Get payment details by ID.

payment = client.get_payment("payment-id-123")

list_payments(params=None)

List payments with optional filters.

from blaziumpay import ListPaymentsParams, PaymentStatus

response = client.list_payments(
    ListPaymentsParams(
        status=PaymentStatus.CONFIRMED,
        currency="USD",
        page=1,
        pageSize=20
    )
)

for payment in response.data:
    print(f"{payment.id}: {payment.amount} {payment.currency}")

cancel_payment(paymentId)

Cancel a pending payment.

payment = client.cancel_payment("payment-id-123")

get_stats()

Get payment statistics.

stats = client.get_stats()
print(f"Total: {stats.total}, Confirmed: {stats.confirmed}")

get_balance(chain)

Get merchant balance for a specific chain.

balance = client.get_balance("TON")
print(f"Available: {balance.availableBalance} TON")

request_withdrawal(request)

Request a withdrawal.

from blaziumpay import WithdrawalRequest

withdrawal = client.request_withdrawal(
    WithdrawalRequest(
        chain="TON",
        amount=10.5,
        destinationAddress="UQD4f0TZeNio8vgobNhnB9xa1bXptEKgr2Kaxi8zu1JIfzEJ"
    )
)

list_withdrawals()

List withdrawal history.

withdrawals = client.list_withdrawals()
for w in withdrawals:
    print(f"{w.id}: {w.amount} {w.chain}")

wait_for_payment(paymentId, timeoutMs=300000, pollIntervalMs=3000)

Wait for a payment to be confirmed (long polling helper).

# Wait up to 5 minutes, polling every 3 seconds
payment = client.wait_for_payment("payment-id-123")

verify_webhook_signature(payload, signature)

Verify webhook signature.

is_valid = client.verify_webhook_signature(raw_body, signature)

parse_webhook(rawPayload, signature)

Parse and verify webhook payload.

webhook = client.parse_webhook(raw_body, signature)

Utility Methods

client.is_paid(payment)              # True if CONFIRMED
client.is_partially_paid(payment)     # True if underpaid
client.is_expired(payment)            # True if expired
client.is_final(payment)              # True if no more updates
client.get_payment_progress(payment)  # % of amount paid (0-100)
client.format_amount(1.5, 'TON')      # "1.5000 TON"

Error Handling

The SDK provides specific error classes for different scenarios:

from blaziumpay import (
    BlaziumError,
    AuthenticationError,
    ValidationError,
    NetworkError,
    RateLimitError,
    TimeoutError,
    APIError,
    PaymentError,
    PaymentNotFoundError,
    PaymentExpiredError,
)

try:
    payment = client.create_payment(...)
except ValidationError as e:
    print(f"Validation failed: {e.message}")
    print(f"Details: {e.details}")
except AuthenticationError:
    print("Invalid API key")
except RateLimitError as e:
    print(f"Rate limited. Retry after: {e.retryAfter} seconds")
except NetworkError:
    print("Network error occurred")

Type Hints

The SDK is fully typed with Python type hints:

from blaziumpay import Payment, PaymentStatus, BlaziumChain

def process_payment(payment: Payment) -> bool:
    if payment.status == PaymentStatus.CONFIRMED:
        return True
    return False

Security Best Practices

1. Never trust frontend signals - Always verify payments server-side
2. Verify webhook signatures - Use verify_webhook_signature() - CRITICAL for security
3. Use idempotency keys - Prevent duplicate payments
4. Implement your own reward logic - BlaziumPay does NOT automatically grant rewards. You must implement webhook handlers to grant premium features, add currency, or perform other actions
5. Use rewardAmount as metadata - Store what you promise users, but implement your own logic to grant it
6. Store API keys securely - Use environment variables
7. Implement timeout handling - Network issues happen
8. Log webhook failures - Monitor for issues
9. Make webhook handlers idempotent - Handle duplicate webhook deliveries gracefully
