Stytch Python Library

The Stytch Python library makes it easy to use the Stytch user infrastructure API in Python applications.

It pairs well with the Stytch Web SDK or your own custom authentication flow.

Requirements

The Stytch Python library supports Python 3.10+

Installation

pip install stytch

Usage

You can find your API credentials in the Stytch Dashboard.

This client library supports all Stytch's live products:

B2C

B2B

Example B2C usage

Create an API client:

import stytch

client = stytch.Client(
    project_id="project-live-c60c0abe-c25a-4472-a9ed-320c6667d317",
    secret="secret-live-80JASucyk7z_G8Z-7dVwZVGXL5NT_qGAQ2I=",
    # Optionally specify a custom base URL for all API calls
    # custom_base_url="https://api.custom-domain.com/",
)

Send a magic link by email:

login_or_create_resp = client.magic_links.email.login_or_create(
    email="sandbox@stytch.com",
    login_magic_link_url="https://example.com/authenticate",
    signup_magic_link_url="https://example.com/authenticate",
)
# Responses are fully-typed `pydantic` objects
print(login_or_create_resp)

Authenticate the token from the magic link:

auth_resp = client.magic_links.authenticate(
    token="DOYoip3rvIMMW5lgItikFK-Ak1CfMsgjuiCyI7uuU94=",
)
print(auth_resp)

Async support

Every endpoint supports an async version which you can use by appending _async to the method name. You can use the same Client object for sync and async methods. The above example of sending and authenticating an magic link can be rewritten as:

login_or_create_resp = await client.magic_links.email.login_or_create_async(
    email="sandbox@stytch.com",
    login_magic_link_url="https://example.com/authenticate",
    signup_magic_link_url="https://example.com/authenticate",
)
print(login_or_create_resp)

auth_resp = await client.magic_links.authenticate(
    token="DOYoip3rvIMMW5lgItikFK-Ak1CfMsgjuiCyI7uuU94=",
)
print(resp)

Example B2B usage

Create an API client:

Python:

import stytch

client = stytch.B2BClient(
    project_id="project-live-c60c0abe-c25a-4472-a9ed-320c6667d317",
    secret="secret-live-80JASucyk7z_G8Z-7dVwZVGXL5NT_qGAQ2I=",
    # Optionally specify a custom base URL for all API calls
    # custom_base_url="https://api.custom-domain.com/",
)

Create an organization

response = client.organizations.create(
    organization_name="Acme Co",
    organization_slug="acme-co",
    email_allowed_domains=["acme.co"]
)

Log the first user into the organization

response = client.magic_links.email.login_or_signup(
    organization_id="ORGANIZATION_ID_FROM_RESPONSE",
    email_address="admin@acme.co",
    login_redirect_url="https://example.com/authenticate",
    signup_redirect_url="https://example.com/authenticate"
)

Handling Errors

Structured errors from the Stytch API will raise StytchError exceptions. You can view the details of the error through the .details property of the StytchError exception.

from stytch.core.response_base import StytchError

try:
    auth_resp = await client.magic_links.authenticate_async(token="token")
except StytchError as error:
    # Handle Stytch errors here
    if error.details.error_type == "invalid_token":
        print("Whoops! Try again?")
except Exception as error:
    # Handle other errors here
    pass

Learn more about errors in the docs.
