merchant = client.merchant.get()
print(f"Merchant: {merchant.merchant_profile.merchant_code}")

Async Client

import asyncio
from sumup import AsyncSumup

async def main():
    client = AsyncSumup(api_key="sup_sk_MvxmLOl0...")
    
    # Get merchant profile
    merchant = await client.merchant.get()
    print(f"Merchant: {merchant.merchant_profile.merchant_code}")

asyncio.run(main())

Creating a Checkout

from sumup import Sumup
from sumup.checkouts import CreateCheckoutBody
import uuid

client = Sumup(api_key="sup_sk_MvxmLOl0...")

# Get merchant code
merchant = client.merchant.get()
merchant_code = merchant.merchant_profile.merchant_code

# Create a checkout
checkout = client.checkouts.create(
    body=CreateCheckoutBody(
        amount=10.00,
        currency="EUR",
        checkout_reference=str(uuid.uuid4()),
        merchant_code=merchant_code,
        description="Test payment",
        redirect_url="https://example.com/success",
        return_url="https://example.com/webhook"
    )
)

print(f"Checkout ID: {checkout.id}")
print(f"Checkout Reference: {checkout.checkout_reference}")

Creating a Reader Checkout

from sumup import Sumup
from sumup.readers import CreateReaderCheckoutBody, CreateReaderCheckoutAmount

client = Sumup(api_key="sup_sk_MvxmLOl0...")

# Create a reader checkout
reader_checkout = client.readers.create_checkout(
    reader_id="your-reader-id",
    body=CreateReaderCheckoutBody(
        total_amount=CreateReaderCheckoutAmount(
            value=1000,  # 10.00 EUR (amount in cents)
            currency="EUR",
            minor_unit=2
        ),
        description="Coffee purchase",
        return_url="https://example.com/webhook"
