Client library for the increase API
Project description
Increase Python API Library
The Increase Python library provides convenient access to the Increase REST API from any Python 3.7+ application. It includes type definitions for all request params and response fields, and offers both synchronous and asynchronous clients powered by httpx.
Documentation
The API documentation can be found here.
Installation
pip install increase
Usage
from increase import Increase
increase = Increase(
# defaults to os.environ.get("INCREASE_API_KEY")
api_key="my api key",
# defaults to "production".
environment="sandbox",
)
account = increase.accounts.create({
"name": "Jane Doe",
})
print(account.id)
While you can provide an api_key
keyword argument, we recommend using python-dotenv
and adding INCREASE_API_KEY="my api key"
to your .env
file so that your API keys are not stored in source control.
Async Usage
Simply import AsyncIncrease
instead of Increase
and use await
with each API call:
from increase import AsyncIncrease
increase = AsyncIncrease(
# defaults to os.environ.get("INCREASE_API_KEY")
api_key="my api key",
# defaults to "production".
environment="sandbox",
)
async def main():
account = await increase.accounts.create({
"name": "Jane Doe"
})
print(account.id)
asyncio.run(main())
Functionality between the synchronous and asynchronous clients are otherwise identical.
Using Types
Request parameters are TypedDicts, while responses are Pydantic models. This helps provide autocomplete and documentation within your editor.
If you would like to see type errors in VS Code to help catch bugs earlier, set python.analysis.typeCheckingMode
to "basic"
.
Pagination
List methods in the Increase API are paginated.
This library provides auto-paginating iterators with each list response, so you do not have to request successive pages manually:
from typing import List
import increase
increase = Increase()
all_accounts = []
# Automatically fetches more pages as needed.
for account in increase.accounts.list():
# Do something with account here
all_accounts.append(account)
return all_accounts
Or, asynchronously:
import asyncio
from typing import List
import increase
increase = AsyncIncrease()
async def main() -> None:
all_accounts = []
# Iterate through items across all pages, issuing requests as needed.
async for account in increase.accounts.list():
all_accounts.append(account)
return all_accounts
asyncio.run(main())
Alternatively, you can use the .has_next_page()
, .next_page_params()
,
or .get_next_page()
methods for more granular control working with pages:
first_page = await client.cards.list({"page_size": 2})
if first_page.has_next_page():
print("will fetch next page, with params", first_page.next_page_params())
next_page = await first_page.get_next_page()
print(f"number of items we just fetched: {len(next_page.data)}")
# Remove `await` for non-async usage.
Or just work directly with the returned data:
first_page = await client.cards.list()
print(f"page number: {first_page.page}") # => "page number: 1"
for card in first_page.data:
print(card.token)
# Remove `await` for non-async usage.
Handling errors
When the library is unable to connect to the API (e.g., due to network connection problems or a timeout), a subclass of increase.APIConnectionError
is raised.
When the API returns a non-success status code (i.e., 4xx or 5xx
response), a subclass of increase.APIStatusError
will be raised, containing status_code
and response
properties.
All errors inherit from increase.APIError
.
from increase import Increase
increase = Increase()
try:
increase.accounts.create({
"naem": "Oops"
})
except increase.APIConnectionError as e:
print("The server could not be reached")
print(e.__cause__) # an underlying Exception, likely raised within httpx.
except increase.RateLimitError as e:
print("A 429 status code was received; we should back off a bit.")
except increase.APIStatusError as e:
print("Another non-200-range status code was received")
print(e.status_code)
print(e.response)
Error codes are as followed:
Status Code | Error Type |
---|---|
400 | BadRequestError |
401 | AuthenticationError |
403 | PermissionDeniedError |
404 | NotFoundError |
422 | UnprocessableEntityError |
429 | RateLimitError |
>=500 | InternalServerError |
N/A | APIConnectionError |
Retries
Certain errors will be automatically retried 2 times by default, with a short exponential backoff. Connection errors (for example, due to a network connectivity problem), 409 Conflict, 429 Rate Limit, and >=500 Internal errors will all be retried by default.
You can use the max_retries
option to configure or disable this:
from increase import Increase
# Configure the default for all requests:
increase = Increase(
# default is 2
max_retries=0,
)
# Or, configure per-request:
increase.accounts.create({
"name": "Jack"
}, max_retries=5);
Timeouts
Requests time out after 60 seconds by default. You can configure this with a timeout
option,
which accepts a float or an httpx.Timeout
:
from increase import Increase
# Configure the default for all requests:
increase = Increase(
# default is 60s
timeout=20.0,
)
# More granular control:
increase = Increase(
timeout=httpx.Timeout(60.0, read=5.0, write=10.0, connect=2.0),
)
# Override per-request:
increase.accounts.list({
"status": "open"
}, timeout=5 * 1000)
On timeout, an APITimeoutError
is thrown.
Note that requests which time out will be retried twice by default.
Advanced: Configuring custom URLs, proxies, and transports
You can configure the following keyword arguments when instantiating the client:
import httpx
from increase import Increase
increase = Increase(
# Use a custom base URL
base_url="http://my.test.server.example.com:8083",
proxies="http://my.test.proxy.example.com",
transport=httpx.HTTPTransport(local_address="0.0.0.0"),
)
See the httpx documentation for information about the proxies
and transport
keyword arguments.
Status
This package is in beta. Its internals and interfaces are not stable and subject to change without a major semver bump; please reach out if you rely on any undocumented behavior.
We are keen for your feedback; please email us at dev-feedback@increase.com or open an issue with questions, bugs, or suggestions.
Requirements
Python 3.7 or higher.
