This release is a pre-release and may not be stable for production use.
SDK for the Seam API written in Python.
Description
Seam makes it easy to integrate IoT devices with your applications. This is an official SDK for the Seam API. Please refer to the official Seam Docs to get started.
Parts of this SDK are generated from always up-to-date type information provided by @seamapi/types node package. This ensures all API methods, request shapes, and response shapes are accurate and fully typed.
Contents
Installation
This package is registered on the Python Package Index (PyPI) as seam.
Install it with:
$ pip install seam
Usage
Examples
Note: These examples assume `SEAM_API_KEY` is set in your environment.
List devices
from seam import Seam
seam = Seam()
devices = seam.devices.list()Unlock a door
from seam import Seam
seam = Seam()
lock = seam.locks.get(name="Front Door")
seam.locks.unlock_door(device_id=lock.device_id)Authentication Method
The SDK supports API key and personal access token authentication mechanisms. Authentication may be configured by passing the corresponding options directly to the Seam constructor, or with the more ergonomic static factory methods.
API Key
An API key is scoped to a single workspace and should only be used on the server. Obtain one from the Seam Console.
# Set the `SEAM_API_KEY` environment variable
seam = Seam()
# Pass as the first argument to the constructor
seam = Seam("your-api-key")
# Pass as a keyword argument to the constructor
seam = Seam(api_key="your-api-key")
# Use the factory method
seam = Seam.from_api_key("your-api-key")Personal Access Token
A Personal Access Token is scoped to a Seam Console user. Obtain one from the Seam Console. A workspace ID must be provided when using this method and all requests will be scoped to that workspace.
# Set the `SEAM_PERSONAL_ACCESS_TOKEN` and `SEAM_WORKSPACE_ID` environment variables
seam = Seam()
# Pass as an option to the constructor
seam = Seam(
personal_access_token="your-personal-access-token",
workspace_id="your-workspace-id",
)
# Use the factory method
seam = Seam.from_personal_access_token(
"your-personal-access-token",
"your-workspace-id",
)Action Attempts
Some asynchronous operations, e.g., unlocking a door, return an action attempt. Seam tracks the progress of the requested operation and updates the action attempt when it succeeds or fails.
To make working with action attempts more convenient for applications, this library provides the wait_for_action_attempt option and enables it by default.
When the wait_for_action_attempt option is enabled, the SDK:
Polls the action attempt up to the timeout at the polling_interval (both in seconds).
Resolves with a fresh copy of the successful action attempt.
Raises a SeamActionAttemptFailedError if the action attempt is unsuccessful.
Raises a SeamActionAttemptTimeoutError if the action attempt is still pending when the timeout is reached.
Both errors expose an action_attempt property.
If you already have an action attempt ID and want to wait for it to resolve, simply use
seam.action_attempts.get(action_attempt_id=action_attempt_id)Or, to get the current state of an action attempt by ID without waiting,
seam.action_attempts.get(
action_attempt_id=action_attempt_id,
wait_for_action_attempt=False,
)To disable this behavior, set the default option for the client:
seam = Seam(
api_key="your-api-key",
wait_for_action_attempt=False,
)
seam.locks.unlock_door(device_id=device_id)or the behavior may be configured per-request:
seam.locks.unlock_door(
device_id=device_id,
wait_for_action_attempt=False,
)The polling_interval and timeout may be configured for the client or per-request. For example:
from seam import Seam, SeamActionAttemptFailedError, SeamActionAttemptTimeoutError
seam = Seam("your-api-key")
lock = seam.locks.list()
if len(locks) == 0:
raise Exception("No locks in this workspace")
lock = locks[0]
try:
seam.locks.unlock_door(
device_id=lock.device_id,
wait_for_action_attempt={
"timeout": 5.0,
"polling_interval": 1.0,
},
)
print("Door unlocked")
except SeamActionAttemptFailedError as e:
print("Could not unlock the door")
except SeamActionAttemptTimeoutError as e:
print("Door took too long to unlock")Pagination
Some Seam API endpoints that return lists of resources support pagination. Use the SeamPaginator class to fetch and process resources across multiple pages.
Manually fetch pages with the next_page_cursor
from seam import Seam
seam = Seam()
paginator = seam.create_paginator(seam.devices.list, {"limit": 20})
devices, pagination = paginator.first_page()
if pagination.has_next_page:
more_devices, _ = paginator.next_page(pagination.next_page_cursor)Resume pagination
Get the first page on initial load and store the state (e.g., in memory or a file):
import json
from seam import Seam
seam = Seam()
params = {"limit": 20}
paginator = seam.create_paginator(seam.devices.list, params)
devices, pagination = paginator.first_page()
# Example: Store state for later use (e.g., in a file or database)
pagination_state = {
"params": params,
"next_page_cursor": pagination.next_page_cursor,
"has_next_page": pagination.has_next_page,
}
with open("/tmp/seam_devices_list.json", "w") as f:
json.dump(pagination_state, f)Get the next page at a later time using the stored state:
import json
from seam import Seam
seam = Seam()
# Example: Load state from where it was stored
with open("/tmp/seam_devices_list.json", "r") as f:
pagination_state = json.load(f)
if pagination_state.get("has_next_page"):
paginator = seam.create_paginator(
seam.devices.list, pagination_state["params"]
)
more_devices, _ = paginator.next_page(
pagination_state["next_page_cursor"]
)Iterate over all resources
from seam import Seam
seam = Seam()
paginator = seam.create_paginator(seam.devices.list, {"limit": 20})
for account in paginator.flatten():
print(account.account_type_display_name)Return all resources across all pages as a list
from seam import Seam
seam = Seam()
paginator = seam.create_paginator(seam.devices.list, {"limit": 20})
all_devices = paginator.flatten_to_list()Requests without a Workspace in Scope
Some Seam API endpoints do not require a workspace in scope. The SeamWithoutWorkspace client is not bound to a specific workspace and may use those endpoints with an appropriate authentication method.
Personal Access Token without a Workspace
A Personal Access Token is scoped to a Seam Console user. Obtain one from the Seam Console.
from seam import SeamWithoutWorkspace
# Set the `SEAM_PERSONAL_ACCESS_TOKEN` environment variable
seam = SeamWithoutWorkspace()
# Pass as an option to the constructor
seam = SeamWithoutWorkspace(personal_access_token="your-personal-access-token")
# Use the factory method
seam = SeamWithoutWorkspace.from_personal_access_token("your-personal-access-token")
# List workspaces authorized for this Personal Access Token
workspaces = seam.workspaces.list()Webhooks
The Seam API implements webhooks using Svix. This SDK exports a thin wrapper SeamWebhook around the svix package. Use it to parse and validate Seam webhook events.
Refer to the Svix docs on Consuming Webhooks for an in-depth guide on best-practices for handling webhooks in your application.
This example is for Flask, see the Svix docs for more examples in specific frameworks.
import os
from flask import Flask, request
from seam import SeamWebhook
app = Flask(__name__)
webhook = SeamWebhook(os.getenv('SEAM_WEBHOOK_SECRET'))
@app.route('/webhook', methods=['POST'])
def handle_webhook():
try:
data = webhook.verify(request.get_data(), request.headers)
except Exception:
return 'Bad Request', 400
try:
store_event(data)
except Exception:
return 'Internal Server Error', 500
return '', 204
def store_event(data):
print(data)
if __name__ == '__main__':
app.run(port=8080)Advanced Usage
Setting the endpoint
Some contexts may need to override the API endpoint, e.g., testing or proxy setups.
Either pass the endpoint option to the constructor, or set the SEAM_ENDPOINT environment variable.
Setting the request timeout
Requests time out after 30 seconds by default. Pass the timeout option, in seconds, to override this:
from seam import Seam
seam = Seam(api_key="your-api-key", timeout=60)Setting it to None disables the timeout entirely.
A request that exceeds the timeout raises httpx.TimeoutException.
Configuring retries
By default, the SDK makes up to three attempts: the initial request and two retries. Retries are limited to GET, HEAD, OPTIONS, PUT, and DELETE requests that fail because of a transport error, timeout, HTTP 429 response, or HTTP 5xx response. POST and PATCH requests are not retried.
Retries use exponential backoff with jitter: approximately 200–240 ms before the first retry and 400–480 ms before the second. A Retry-After header is honored instead of the calculated backoff. The request timeout is reset for each attempt.
Pass the retries option to configure retry behavior. Retries are handled by httpx-retries, and its Retry class is re-exported from seam for convenience:
from seam import Seam, Retry
seam = Seam(
api_key="your-api-key",
retries=Retry(total=3, backoff_factor=0.5, status_forcelist=[503]),
)Configuring the httpx client
For control the options above do not cover, pass httpx_options. These are handed to the underlying httpx Client and take precedence over the defaults the SDK sets:
from httpx import Limits
seam = Seam(
api_key="your-api-key",
httpx_options={
"limits": Limits(max_connections=25, max_keepalive_connections=20),
},
)Development and Testing

Manual
Publish a new version by triggering a version workflow_dispatch on GitHub Actions. The version input will be passed as the first argument to uv version.
This may be done on the web or using the GitHub CLI with
$ gh workflow run version.yml --raw-field version=<version>
GitHub Actions
GitHub Actions should already be configured: this section is for reference only.
The following repository secrets must be set on GitHub Actions.
PYPI_API_TOKEN: API token for publishing on PyPI.
These must be set manually.
Secrets for Optional GitHub Actions
The version, format, generate, and semantic-release GitHub actions require a user with write access to the repository including access to read and write packages. Set these additional secrets to enable the action:
GH_TOKEN: A personal access token for the user.
GIT_USER_NAME: The name to set for Git commits.
GIT_USER_EMAIL: The email to set for Git commits.
GPG_PRIVATE_KEY: The GPG private key.
GPG_PASSPHRASE: The GPG key passphrase.
