SDK Installation

Note

Python version upgrade policy

Once a Python version reaches its official end of life date, a 3-month grace period is provided for users to upgrade. Following this grace period, the minimum python version supported in the SDK will be updated.

The SDK can be installed with either pip or poetry package managers.

PIP

PIP is the default package installer for Python, enabling easy installation and management of packages from PyPI via the command line.

pip install dub

Poetry

Poetry is a modern tool that simplifies dependency management and package publishing by using a single pyproject.toml file to handle project metadata and dependencies.

poetry add dub

Shell and script usage with uv

You can use this SDK in a Python shell with uv and the uvx command that comes with it like so:

uvx --from dub python

It's also possible to write a standalone Python script without needing to set up a whole project like so:

#!/usr/bin/env -S uv run --script
# /// script
# requires-python = ">=3.9"
# dependencies = [
#     "dub",
# ]
# ///

from dub import Dub

sdk = Dub(
  # SDK arguments
)

# Rest of script here...

Once that is saved to a file, you can run it with uv run script.py where script.py can be replaced with the actual file name.

SDK Example Usage

Example 1

# Synchronous Example
from dub import Dub


with Dub(
    token="DUB_API_KEY",
) as d_client:

    res = d_client.links.create(request={
        "url": "https://google.com",
        "external_id": "123456",
        "tag_ids": [
            "clux0rgak00011...",
        ],
        "test_variants": [
            {
                "url": "https://example.com/variant-1",
                "percentage": 50,
            },
            {
                "url": "https://example.com/variant-2",
                "percentage": 50,
            },
        ],
    })

    assert res is not None

    # Handle response
    print(res)

The same SDK client can also be used to make asychronous requests by importing asyncio.

# Asynchronous Example
import asyncio
from dub import Dub

async def main():

    async with Dub(
        token="DUB_API_KEY",
    ) as d_client:

        res = await d_client.links.create_async(request={
            "url": "https://google.com",
            "external_id": "123456",
            "tag_ids": [
                "clux0rgak00011...",
            ],
            "test_variants": [
                {
                    "url": "https://example.com/variant-1",
                    "percentage": 50,
                },
                {
                    "url": "https://example.com/variant-2",
                    "percentage": 50,
                },
            ],
        })

        assert res is not None

        # Handle response
        print(res)

asyncio.run(main())

with Dub(
    token="DUB_API_KEY",
) as d_client:
    res = None
    try:

        res = d_client.links.create(request={

        assert res is not None

        # Handle response
        print(res)


    except errors.DubError as e:
        # The base class for HTTP error responses
        print(e.message)
        print(e.status_code)
        print(e.body)

        print(e.raw_response)

        # Depending on the method different errors may be thrown
        if isinstance(e, errors.BadRequest):
            print(e.data.error)  # errors.Error

Error Classes

Primary errors:

  • DubError: The base class for HTTP error responses.
    • BadRequest: The server cannot or will not process the request due to something that is perceived to be a client error (e.g., malformed request syntax, invalid request message framing, or deceptive request routing). Status code 400.
    • Unauthorized: Although the HTTP standard specifies "unauthorized", semantically this response means "unauthenticated". That is, the client must authenticate itself to get the requested response. Status code 401.
    • Forbidden: The client does not have access rights to the content; that is, it is unauthorized, so the server is refusing to give the requested resource. Unlike 401 Unauthorized, the client's identity is known to the server. Status code 403.
    • NotFound: The server cannot find the requested resource. Status code 404.
    • Conflict: This response is sent when a request conflicts with the current state of the server. Status code 409.
    • InviteExpired: This response is sent when the requested content has been permanently deleted from server, with no forwarding address. Status code 410.
    • UnprocessableEntity: The request was well-formed but was unable to be followed due to semantic errors. Status code 422.
    • RateLimitExceeded: The user has sent too many requests in a given amount of time ("rate limiting"). Status code 429.
    • InternalServerError: The server has encountered a situation it does not know how to handle. Status code 500.
Less common errors (5)

Network errors:

Inherit from DubError:

  • ResponseValidationError: Type mismatch between the response data and the expected Pydantic model. Provides access to the Pydantic validation error via the cause attribute.

Server Selection

Override Server URL Per-Client

The default server can be overridden globally by passing a URL to the server_url: str optional parameter when initializing the SDK client instance. For example:

from dub import Dub


with Dub(
    server_url="https://api.dub.co",
    token="DUB_API_KEY",
) as d_client:

    res = d_client.links.create(request={
        "url": "https://google.com",
        "external_id": "123456",
        "tag_ids": [
            "clux0rgak00011...",
        ],
        "test_variants": [
            {
                "url": "https://example.com/variant-1",
                "percentage": 50,
            },
            {
                "url": "https://example.com/variant-2",
                "percentage": 50,
            },
        ],
    })

    assert res is not None

    # Handle response
    print(res)

Custom HTTP Client

The Python SDK makes API calls using the httpx HTTP library. In order to provide a convenient way to configure timeouts, cookies, proxies, custom headers, and other low-level configuration, you can initialize the SDK client with your own HTTP client instance. Depending on whether you are using the sync or async version of the SDK, you can pass an instance of HttpClient or AsyncHttpClient respectively, which are Protocol's ensuring that the client has the necessary methods to make API calls. This allows you to wrap the client with your own custom logic, such as adding custom headers, logging, or error handling, or you can just pass an instance of httpx.Client or httpx.AsyncClient directly.

For example, you could specify a header for every request that this sdk makes as follows:

from dub import Dub
import httpx

http_client = httpx.Client(headers={"x-custom-header": "someValue"})
s = Dub(client=http_client)

or you could wrap the client with your own custom logic:

from dub import Dub
from dub.httpclient import AsyncHttpClient
import httpx

class CustomClient(AsyncHttpClient):
    client: AsyncHttpClient

    def __init__(self, client: AsyncHttpClient):
        self.client = client

    async def send(
        self,
        request: httpx.Request,
        *,
        stream: bool = False,
        auth: Union[
            httpx._types.AuthTypes, httpx._client.UseClientDefault, None
        ] = httpx.USE_CLIENT_DEFAULT,
        follow_redirects: Union[
            bool, httpx._client.UseClientDefault
        ] = httpx.USE_CLIENT_DEFAULT,
    ) -> httpx.Response:
        request.headers["Client-Level-Header"] = "added by client"

        return await self.client.send(
            request, stream=stream, auth=auth, follow_redirects=follow_redirects
        )

    def build_request(
        self,
        method: str,
        url: httpx._types.URLTypes,
        *,
        content: Optional[httpx._types.RequestContent] = None,
        data: Optional[httpx._types.RequestData] = None,
        files: Optional[httpx._types.RequestFiles] = None,
        json: Optional[Any] = None,
        params: Optional[httpx._types.QueryParamTypes] = None,
        headers: Optional[httpx._types.HeaderTypes] = None,
        cookies: Optional[httpx._types.CookieTypes] = None,
        timeout: Union[
            httpx._types.TimeoutTypes, httpx._client.UseClientDefault
        ] = httpx.USE_CLIENT_DEFAULT,
        extensions: Optional[httpx._types.RequestExtensions] = None,
    ) -> httpx.Request:
        return self.client.build_request(
            method,
            url,
            content=content,
            data=data,
            files=files,
            json=json,
            params=params,
            headers=headers,
            cookies=cookies,
            timeout=timeout,
            extensions=extensions,
        )

s = Dub(async_client=CustomClient(httpx.AsyncClient()))

Authentication

Per-Client Security Schemes

This SDK supports the following security scheme globally:

Name Type Scheme
token http HTTP Bearer

To authenticate with the API the token parameter must be set when initializing the SDK client instance. For example:

from dub import Dub


with Dub(
    token="DUB_API_KEY",
) as d_client:

    res = d_client.links.create(request={
        "url": "https://google.com",
        "external_id": "123456",
        "tag_ids": [
            "clux0rgak00011...",
        ],
        "test_variants": [
            {
                "url": "https://example.com/variant-1",
                "percentage": 50,
            },
            {
                "url": "https://example.com/variant-2",
                "percentage": 50,
            },
        ],
    })

    assert res is not None

    # Handle response
    print(res)

Retries

Some of the endpoints in this SDK support retries. If you use the SDK without any configuration, it will fall back to the default retry strategy provided by the API. However, the default retry strategy can be overridden on a per-operation basis, or across the entire SDK.

To change the default retry strategy for a single API call, simply provide a RetryConfig object to the call:

from dub import Dub
from dub.utils import BackoffStrategy, RetryConfig


with Dub(
    token="DUB_API_KEY",
) as d_client:

    res = d_client.links.create(request={
        "url": "https://google.com",
        "external_id": "123456",
        "tag_ids": [
            "clux0rgak00011...",
        ],
        "test_variants": [
            {
                "url": "https://example.com/variant-1",
                "percentage": 50,
            },
            {
                "url": "https://example.com/variant-2",
                "percentage": 50,
            },
        ],
    },
        RetryConfig("backoff", BackoffStrategy(1, 50, 1.1, 100), False))

    assert res is not None

    # Handle response
    print(res)

If you'd like to override the default retry strategy for all operations that support retries, you can use the retry_config optional parameter when initializing the SDK:

from dub import Dub
from dub.utils import BackoffStrategy, RetryConfig


with Dub(
    retry_config=RetryConfig("backoff", BackoffStrategy(1, 50, 1.1, 100), False),
    token="DUB_API_KEY",
) as d_client:

    res = d_client.links.create(request={
        "url": "https://google.com",
        "external_id": "123456",
        "tag_ids": [
            "clux0rgak00011...",
        ],
        "test_variants": [
            {
                "url": "https://example.com/variant-1",
                "percentage": 50,
            },
            {
                "url": "https://example.com/variant-2",
                "percentage": 50,
            },
        ],
    })

    assert res is not None

    # Handle response
    print(res)

Pagination

Some of the endpoints in this SDK support pagination. To use pagination, you make your SDK calls as usual, but the returned response object will have a Next method that can be called to pull down the next group of results. If the return value of Next is None, then there are no more pages to be fetched.

Here's an example of one such pagination call:

from dub import Dub


with Dub(
    token="DUB_API_KEY",
) as d_client:

    res = d_client.links.list(request={
        "page_size": 50,
    })

    while res is not None:
        # Handle items

        res = res.next()

Resource Management

The Dub class implements the context manager protocol and registers a finalizer function to close the underlying sync and async HTTPX clients it uses under the hood. This will close HTTP connections, release memory and free up other resources held by the SDK. In short-lived Python programs and notebooks that make a few SDK method calls, resource management may not be a concern. However, in longer-lived programs, it is beneficial to create a single SDK instance via a context manager and reuse it across the application.

from dub import Dub
def main():

    with Dub(
        token="DUB_API_KEY",
    ) as d_client:
        # Rest of application here...


# Or when using async:
async def amain():

    async with Dub(
        token="DUB_API_KEY",
    ) as d_client:
        # Rest of application here...

Debugging

You can setup your SDK to emit debug logs for SDK requests and responses.

You can pass your own logger class directly into your SDK.

from dub import Dub
import logging

logging.basicConfig(level=logging.DEBUG)
s = Dub(debug_logger=logging.getLogger("dub"))

IDE Support

PyCharm

Generally, the SDK will work well with most IDEs out of the box. However, when using PyCharm, you can enjoy much better integration with Pydantic by installing an additional plugin.
