MakePay Python SDK

Overview

The MakePay Python SDK is the dependency-free Python package for MakePay server-side integrations. Use it to create crypto payment links, donation pages, invoices, bookkeeping records, subscriptions, POS terminals, products, Simple Shop storefronts, customer portals, branded domains, and signed webhook handlers.

Package:

makepay

Installation

pip install makepay

uv add makepay

The SDK targets Python 3.9 or newer and uses Python standard library HTTP and crypto modules.

Authentication

Create a MakePay API key from the MakeCrypto merchant developer area and store the key secret only on your server.

import os

from makepay import MakePayClient

makepay = MakePayClient(
    key_id=os.environ["MAKEPAY_KEY_ID"],
    key_secret=os.environ["MAKEPAY_KEY_SECRET"],
)

The SDK sends X-MakeCrypto-Key-Id and X-MakeCrypto-Key-Secret headers to the MakePay partner API.

Payment Links

response = makepay.create_payment_link(
    {
        "title": "Order #1042",
        "description": "Checkout for order #1042",
        "amount": "129.99",
        "currency": "USDT",
        "orderId": "order_1042",
        "customerEmail": "buyer@example.com",
        "returnUrl": "https://merchant.example/orders/1042",
        "successUrl": "https://merchant.example/orders/1042/success",
        "failureUrl": "https://merchant.example/orders/1042/pay",
        "expirationTime": "12h",
    }
)

print(response["paymentLink"])

Read, update, and email existing links:

makepay.list_payment_links()
makepay.get_payment_link("PAYMENT_LINK_UID")
makepay.update_payment_link("PAYMENT_LINK_UID", {"status": "paused"})
makepay.send_payment_request_email("PAYMENT_LINK_UID", "buyer@example.com")

Donations

Donation pages are flexible-amount payment links with a public donation slug.

donation = makepay.create_donation_link(
    {
        "title": "Spring campaign",
        "description": "Support the 2026 spring fundraiser.",
        "defaultAmountUsd": "25",
        "minimumAmountUsd": "5",
        "donationSlug": "spring-campaign",
    }
)

print(donation["paymentLink"]["publicUrl"])

makepay.list_donation_links()
makepay.get_donation_link("DONATION_UID")
makepay.update_donation_link("DONATION_UID", {"status": "paused"})

Anonymous Payment Links

Anonymous links do not use a MakePay API key. They require an explicit settlement route because MakePay cannot read merchant wallet settings.

from makepay import create_anonymous_payment_link

response = create_anonymous_payment_link(
    {
        "amount": "25",
        "settlement": {
            "currency": "USDT",
            "priorities": [
                {
                    "chain": "ETH",
                    "address": "0xYourSettlementWallet",
                    "asset": "ETH.USDT-0xdAC17F958D2ee523a2206206994597C13D831ec7",
                }
            ],
        },
        "title": "Invoice #1042",
        "webhookUrl": "https://merchant.example/webhooks/makepay",
    }
)

Checkout URLs And Embeds

Use hosted checkout for redirects, or the embed helpers when your frontend keeps the shopper on the merchant site.

from makepay import (
    build_makepay_embedded_checkout_url,
    build_makepay_hosted_checkout_url,
    build_makepay_iframe_html,
)

payment_uid = response["paymentLink"]["uid"]

hosted_url = build_makepay_hosted_checkout_url(payment_uid)
embed_url = build_makepay_embedded_checkout_url(
    payment_uid,
    parent_origin="https://merchant.example",
)
iframe_html = build_makepay_iframe_html(payment_uid)

Donation pages also have URL helpers:

makepay.hosted_donation_url("spring-campaign")
makepay.embedded_donation_url(
    "spring-campaign",
    parent_origin="https://merchant.example",
)

For static CMS pages, build_makepay_embed_button_html(payment_uid) returns a button snippet that loads the MakePay modal script.

Customers And Subscriptions

makepay.upsert_customer(
    {
        "email": "buyer@example.com",
        "name": "Buyer Example",
        "clientId": "crm_123",
    }
)

makepay.create_customer_portal(
    "CUSTOMER_ID",
    {"returnUrl": "https://merchant.example/account"},
)

makepay.create_subscription(
    {
        "amountUsd": "29",
        "customerEmail": "buyer@example.com",
        "label": "Monthly plan",
        "billingIntervalUnit": "month",
        "billingIntervalCount": 1,
    }
)

POS Terminals

terminal = makepay.create_pos_terminal(
    {
        "name": "Front counter",
        "pin": "1234",
        "allowedAssets": ["ETH.USDT-0xdAC17F958D2ee523a2206206994597C13D831ec7"],
        "emailCollectionMode": "optional_after_deposit",
        "catalogEnabled": True,
    }
)

makepay.list_pos_terminals()
makepay.get_pos_terminal(str(terminal["terminal"]["uid"]))

Products And Simple Shop

makepay.create_product(
    {
        "name": "Digital guide",
        "productType": "digital",
        "basePriceUsd": "19",
        "shopSlug": "digital-guide",
        "images": [{"url": "https://merchant.example/guide.png", "alt": "Guide cover"}],
        "variants": [{"name": "PDF", "priceUsd": "19"}],
    }
)

makepay.create_product_download(
    "PRODUCT_UID",
    {
        "fileName": "guide.pdf",
        "contentType": "application/pdf",
        "url": "https://merchant.example/downloads/guide.pdf",
    },
)

makepay.update_shop(
    {
        "slug": "merchant-shop",
        "displayCurrency": "USD",
        "checkoutMode": "hosted",
        "branding": {"accentColor": "#14b8a6"},
    }
)

makepay.update_shop_domain("shop.merchant.example")
makepay.refresh_shop_domain()
makepay.create_shop_coupon(
    {
        "code": "SPRING10",
        "discountType": "percent",
        "value": "10",
    }
)
makepay.list_shop_orders({"status": "paid", "limit": 25})

Invoices And Bookkeeping

Bookkeeping APIs manage merchant invoices, expenses, supporting documents, OCR, and reconciliation links.

created = makepay.create_bookkeeping_invoice(
    {
        "title": "Invoice #1042",
        "currency": "USD",
        "issueDate": "2026-05-15",
        "dueDate": "2026-05-30",
        "counterparty": {
            "name": "Buyer Example",
            "email": "buyer@example.com",
            "clientId": "crm_123",
        },
        "lineItems": [
            {
                "description": "Implementation services",
                "quantity": "1",
                "unitAmount": "500",
                "taxAmount": "0",
            }
        ],
        "metadata": {"orderId": "order_1042"},
    }
)

makepay.create_bookkeeping_invoice_payment_link(
    "INVOICE_UID",
    {"sendPaymentRequestEmail": True},
)

makepay.list_bookkeeping_invoices()
makepay.get_bookkeeping_invoice("INVOICE_UID")
makepay.update_bookkeeping_invoice("INVOICE_UID", {"status": "open"})

Expenses can be created manually or from wallet activity, then linked back to payments, transfers, invoices, or uploaded receipts.

makepay.create_bookkeeping_expense(
    {
        "title": "Hosting",
        "amount": "49",
        "currency": "USD",
        "incurredOn": "2026-05-15",
        "category": "Infrastructure",
        "counterparty": {"name": "Vendor Example", "type": "vendor"},
    }
)

makepay.create_bookkeeping_expense_from_activity(
    {
        "walletActivityEventKey": "CHAIN_EVENT_KEY",
        "category": "Settlement",
    }
)

makepay.create_bookkeeping_reconciliation(
    {
        "invoiceId": "INVOICE_UID",
        "paymentSessionId": "PAYMENT_SESSION_ID",
        "linkType": "payment",
    }
)

Document uploads use multipart form data. Pass bytes, a file path, or a readable file object.

with open("receipt.pdf", "rb") as receipt:
    makepay.upload_bookkeeping_document(
        {
            "file": receipt,
            "fileName": "receipt.pdf",
            "documentType": "receipt",
            "expenseId": "EXPENSE_UID",
        }
    )

makepay.list_bookkeeping_documents()
makepay.get_bookkeeping_document_download_url("DOCUMENT_UID")
makepay.run_bookkeeping_document_ocr("DOCUMENT_UID")
makepay.get_bookkeeping_summary()

Branding And Domains

makepay.update_branding(
    {
        "brandName": "Merchant",
        "supportEmail": "support@merchant.example",
        "brandingBrandColor": "#111827",
        "brandingAccentColor": "#14b8a6",
        "paymentLinkTheme": "system",
        "paymentLinkDomain": "pay.merchant.example",
        "emailSendingDomain": "mail.merchant.example",
    }
)

makepay.refresh_branding_domains("all")

Settings And Operational APIs

makepay.get_settings()
makepay.update_settings(
    {
        "callbackUrl": "https://merchant.example/webhooks/makepay",
    }
)

makepay.list_destination_assets()
makepay.list_webhook_requests({"limit": 25})

Webhook Verification

Read the exact raw body before parsing JSON.

import os

from makepay import parse_makepay_webhook


def handle_makepay_webhook(raw_body: bytes, headers: dict[str, str]):
    event = parse_makepay_webhook(
        raw_body,
        headers.get("x-makepay-signature"),
        os.environ["MAKEPAY_WEBHOOK_SECRET"],
    )

    if event.get("event", {}).get("type") == "status_changed":
        # Update your local order status.
        pass

    return "ok", 200

Use verify_makepay_webhook when you only need a boolean result.

Data Models And Response Models

Python payloads are plain dictionaries that use the MakePay API field names. New integrations should send camelCase keys such as customerEmail, paymentLinkDomain, and billingIntervalUnit.

Model conventions:

• Use strings for decimal money values when precision matters, for example "129.99" instead of 129.99.
• Dates are ISO strings. Date-only fields, such as invoice issueDate, should use YYYY-MM-DD.
• IDs are usually public uid values. Bookkeeping detail endpoints accept an internal UUID or public UID.
• API methods raise MakePayError for non-2xx responses. Successful responses are decoded JSON dictionaries, so production can add fields without requiring a Python package update.

Error Handling

API calls raise MakePayError. It includes the HTTP status and decoded response body.

from makepay import MakePayError

try:
    makepay.get_payment_link("PAYMENT_LINK_UID")
except MakePayError as error:
    print(error.status, error.response_body)
