Python

The Python SDK gives Python applications typed access to the Dodo Payments REST API. It has a synchronous client, DodoPayments, and an asynchronous client, AsyncDodoPayments, both built on httpx. Nested request parameters are typed dictionaries, and responses are Pydantic models.

Installation

Install the SDK with pip:

pip install dodopayments

To use aiohttp as the HTTP backend for the async client, install the aiohttp extra:

pip install "dodopayments[aiohttp]"

To verify webhook signatures with client.webhooks.unwrap(), also install the webhooks extra: pip install "dodopayments[webhooks]".

The SDK requires Python 3.9 or later. Use the latest stable Python release to get security updates.

Quick Start

Synchronous Client

Create a client, then create a checkout session:

import os
from dodopayments import DodoPayments

client = DodoPayments(
    bearer_token=os.environ.get("DODO_PAYMENTS_API_KEY"),  # This is the default and can be omitted
    environment="test_mode",  # defaults to "live_mode"
)

checkout_session_response = client.checkout_sessions.create(
    product_cart=[
        {
            "product_id": "pdt_123",
            "quantity": 1
        }
    ],
)
print(checkout_session_response.session_id)

If you omit bearer_token, the client reads the DODO_PAYMENTS_API_KEY environment variable. If you omit environment, the client connects to live mode. A test mode API key works only with environment="test_mode".

Asynchronous Client

AsyncDodoPayments has the same methods as DodoPayments. Await each call:

import os
import asyncio
from dodopayments import AsyncDodoPayments

client = AsyncDodoPayments(
    bearer_token=os.environ.get("DODO_PAYMENTS_API_KEY"),
    environment="test_mode",
)


async def main() -> None:
    checkout_session_response = await client.checkout_sessions.create(
        product_cart=[
            {
                "product_id": "pdt_123",
                "quantity": 1,
            }
        ],
    )
    print(checkout_session_response.session_id)


asyncio.run(main())

Keep API keys in environment variables or a secrets manager. Never commit them to version control.

Core Features

Pythonic Interface

Keyword arguments for parameters, TypedDict types for nested objects, and Pydantic models for responses.

Async/Await

AsyncDodoPayments for asyncio, with aiohttp as an optional HTTP backend.

Type Hints

Type hints on every method, for editor autocomplete and type checking with mypy.

Auto-Pagination

List methods return iterators that fetch the next page as you loop.

Configuration

Environment Variables

Store your API key in an environment variable:

.env

DODO_PAYMENTS_API_KEY=your_api_key_here

The client reads these variables when you don’t pass the matching argument:

Variable	Client argument	Purpose
`DODO_PAYMENTS_API_KEY`	`bearer_token`	Your API key. The client raises an error if neither is set.
`DODO_PAYMENTS_WEBHOOK_KEY`	`webhook_key`	Your webhook signing secret, used to verify webhooks.
`DODO_PAYMENTS_BASE_URL`	`base_url`	A custom API URL that replaces the `environment` URL.
`DODO_PAYMENTS_LOG`	No matching argument	The log level. See Logging.

If DODO_PAYMENTS_BASE_URL is set and you also pass environment, the constructor raises an “Ambiguous URL” error. To use environment in that case, pass base_url=None. To verify a webhook, pass the raw request body and headers to client.webhooks.unwrap(payload, headers=headers). It checks the signature with your webhook key and returns the parsed event. client.webhooks.unsafe_unwrap(payload) parses the body without verifying it, so use it only for testing. See Webhooks.

Timeouts

Requests time out after 1 minute by default, with a 5-second connection timeout. Pass timeout in seconds, or an httpx.Timeout for separate read, write, and connect limits:

import httpx
from dodopayments import DodoPayments

# Configure default for all requests (default is 1 minute)
client = DodoPayments(
    timeout=20.0,  # 20 seconds
)

# More granular control
client = DodoPayments(
    timeout=httpx.Timeout(60.0, read=5.0, write=10.0, connect=2.0),
)

# Override per-request
client.with_options(timeout=5.0).checkout_sessions.create(
    product_cart=[
        {
            "product_id": "pdt_123",
            "quantity": 1,
        }
    ],
)

When a request times out, the SDK raises APITimeoutError. Timed-out requests are retried, so a call can take longer than timeout before it fails.

Retries

Set max_retries on the client, or on a single request with with_options():

from dodopayments import DodoPayments

# Configure default for all requests (default is 2)
client = DodoPayments(
    max_retries=0,  # disable retries
)

# Override per-request
client.with_options(max_retries=5).checkout_sessions.create(
    product_cart=[
        {
            "product_id": "pdt_123",
            "quantity": 1,
        }
    ],
)

The SDK retries connection errors and responses with status 408, 409, 429, or 500 and above. It retries twice by default, with exponential backoff. When a request still fails, the SDK raises a subclass of dodopayments.APIError:

Status	Exception
400	`BadRequestError`
401	`AuthenticationError`
403	`PermissionDeniedError`
404	`NotFoundError`
409	`ConflictError`
422	`UnprocessableEntityError`
429	`RateLimitError`
500 and above	`InternalServerError`
No response	`APIConnectionError`

The status exceptions inherit from dodopayments.APIStatusError, which has status_code and response attributes. APITimeoutError is a subclass of APIConnectionError.

Common Operations

The examples in this section use the client from Quick Start.

Create a Checkout Session

Create a checkout session, then redirect the customer to the returned checkout_url:

session = client.checkout_sessions.create(
    product_cart=[
        {
            "product_id": "pdt_123",
            "quantity": 1
        }
    ],
    return_url="https://yourdomain.com/return"
)

print(f"Checkout URL: {session.checkout_url}")

Each checkout_url works once and expires after 24 hours. For every session option, see Checkout Sessions.

Manage Customers

Create a customer with an email address and name, then retrieve it by ID:

# Create a customer
customer = client.customers.create(
    email="customer@example.com",
    name="John Doe",
    metadata={
        "user_id": "12345"
    }
)

# Retrieve customer
customer = client.customers.retrieve("cus_123")
print(f"Customer: {customer.name} ({customer.email})")

Handle Subscriptions

Create a subscription, charge an on-demand subscription, and read a subscription’s usage history.

POST /subscriptions (the SDK’s subscriptions.create method) is deprecated. It still works for existing integrations, but new integrations should create subscriptions through a Checkout Session.

# Create a subscription
subscription = client.subscriptions.create(
    billing={
        "country": "US",
        "city": "San Francisco",
        "state": "CA",
        "street": "1 Market St",
        "zipcode": "94105",
    },
    customer={"customer_id": "cus_123"},  # or {"email": "...", "name": "..."} for a new customer
    product_id="pdt_456",
    quantity=1,
)

# Charge an on-demand subscription
# product_price is in the lowest currency denomination (e.g., 2500 = $25.00 USD)
charge_response = client.subscriptions.charge(
    subscription_id=subscription.subscription_id,
    product_price=2500,
)

# Retrieve usage history (for metered subscriptions)
usage_history = client.subscriptions.retrieve_usage_history(
    subscription_id=subscription.subscription_id,
    start_date="2024-01-01T00:00:00Z",
)

billing requires only country, a two-letter ISO country code. customer takes {"customer_id": ...} to attach an existing customer or {"email": ..., "name": ...} to create one. charge is for on-demand subscriptions, and product_price is in the smallest currency unit. retrieve_usage_history returns a paginated list, which you can iterate as shown in Pagination.

Usage-Based Billing

Ingest Usage Events

Send usage events for a customer:

from datetime import datetime, timezone

response = client.usage_events.ingest(
    events=[
        {
            "event_id": "api_call_12345",
            "customer_id": "cus_abc123",
            "event_name": "api_request",
            "timestamp": datetime.now(timezone.utc),
            "metadata": {
                "endpoint": "/api/v1/users",
                "method": "GET",
                "tokens_used": "150"
            }
        }
    ]
)

The event_id is the idempotency key, so give each event a unique value. If the same event_id appears twice in one request, the whole request is rejected. If an event_id was already ingested, the new event is ignored. A request accepts up to 1,000 events. timestamp defaults to the current time and is rejected if it’s more than 1 hour in the past or more than 5 minutes in the future.

List and Retrieve Events

Retrieve a single event by its event_id, or list events filtered by customer and event name:

# Get a specific event
event = client.usage_events.retrieve("api_call_12345")

# List events with filtering
events = client.usage_events.list(
    customer_id="cus_abc123",
    event_name="api_request",
    page_size=20
)

for event in events.items:
    print(f"Event: {event.event_id} at {event.timestamp}")

usage_events.list also accepts meter_id, start, and end filters.

Pagination

Auto-Pagination

List methods return an iterator that fetches the next page as you loop:

from dodopayments import DodoPayments

client = DodoPayments()
all_payments = []

# Automatically fetches more pages as needed
for payment in client.payments.list():
    all_payments.append(payment)
print(all_payments)

Async Pagination

With the async client, loop with async for:

import asyncio
from dodopayments import AsyncDodoPayments

client = AsyncDodoPayments()


async def main() -> None:
    all_payments = []
    # Iterate through items across all pages
    async for payment in client.payments.list():
        all_payments.append(payment)
    print(all_payments)


asyncio.run(main())

Manual Pagination

To work with one page at a time, read items and call has_next_page() and get_next_page(). next_page_info() returns the parameters for the next request:

# Access items from current page
first_page = client.payments.list()
for payment in first_page.items:
    print(payment.brand_id)

# Check for more pages
if first_page.has_next_page():
    next_page = first_page.get_next_page()
    print(f"Fetched {len(next_page.items)} more items")

HTTP Client Configuration

To add a proxy, a custom transport, or other httpx settings, pass your own http_client. DefaultHttpxClient keeps the SDK’s default connection limits, timeout, and redirect settings:

import httpx
from dodopayments import DodoPayments, DefaultHttpxClient

client = DodoPayments(
    base_url="http://my.test.server.example.com:8083",
    http_client=DefaultHttpxClient(
        proxy="http://my.test.proxy.example.com",
        transport=httpx.HTTPTransport(local_address="0.0.0.0"),
    ),
)

To use a different HTTP client for one request, call client.with_options(http_client=...).

Async with AIOHTTP

By default, the async client sends requests with httpx. For better concurrency, install the aiohttp extra and pass DefaultAioHttpClient() as http_client:

import os
import asyncio
from dodopayments import DefaultAioHttpClient
from dodopayments import AsyncDodoPayments


async def main() -> None:
    async with AsyncDodoPayments(
        bearer_token=os.environ.get("DODO_PAYMENTS_API_KEY"),
        http_client=DefaultAioHttpClient(),
    ) as client:
        checkout_session_response = await client.checkout_sessions.create(
            product_cart=[
                {
                    "product_id": "pdt_123",
                    "quantity": 1,
                }
            ],
        )
        print(checkout_session_response.session_id)


asyncio.run(main())

Logging

The SDK logs with the standard library logging module. To turn on logging, set DODO_PAYMENTS_LOG to info:

export DODO_PAYMENTS_LOG=info

For more detail, set it to debug:

export DODO_PAYMENTS_LOG=debug

Framework Integration

These examples create a checkout session from a web endpoint and return its URL.

FastAPI

This endpoint uses the async client:

from fastapi import FastAPI, HTTPException
from dodopayments import AsyncDodoPayments
from pydantic import BaseModel
import os

app = FastAPI()
dodo = AsyncDodoPayments(bearer_token=os.getenv("DODO_PAYMENTS_API_KEY"))

class CheckoutRequest(BaseModel):
    product_id: str
    quantity: int

@app.post("/create-checkout")
async def create_checkout(request: CheckoutRequest):
    try:
        session = await dodo.checkout_sessions.create(
            product_cart=[{
                "product_id": request.product_id,
                "quantity": request.quantity
            }],
            return_url="https://yourdomain.com/return"
        )
        return {"checkout_url": session.checkout_url}
    except Exception as e:
        raise HTTPException(status_code=400, detail=str(e))

Django

This view uses the sync client:

from django.http import JsonResponse
from django.views.decorators.http import require_POST
from django.views.decorators.csrf import csrf_exempt
from dodopayments import DodoPayments
import os
import json

client = DodoPayments(bearer_token=os.getenv("DODO_PAYMENTS_API_KEY"))

@csrf_exempt
@require_POST
def create_checkout(request):
    try:
        data = json.loads(request.body)
        session = client.checkout_sessions.create(
            product_cart=[{
                "product_id": data.get("product_id"),
                "quantity": data.get("quantity", 1)
            }],
            return_url="https://yourdomain.com/return"
        )
        return JsonResponse({
            "status": "success",
            "checkout_url": session.checkout_url,
            "session_id": session.session_id
        })
    except Exception as e:
        return JsonResponse({
            "status": "error",
            "message": str(e)
        }, status=400)
