Python Library Reference
PropelAuth’s Python library provides all the building blocks you need to add authentication to any Python backend.
For most Python frameworks, like FastAPI, Django, and Flask, we have built out libraries specifically for them. Those libraries will provide a more first-class experience than this library.
Installation
pip install propelauth_py
Initialize
init_base_auth performs a one-time initialization of the library.
It will verify your api_key
is correct and fetch the metadata needed to verify access tokens in validate_access_token_and_get_user and validate_access_token_and_get_user_with_org.
from propelauth_py import init_base_auth
auth = init_base_auth("YOUR_AUTH_URL", "YOUR_API_KEY")
Protect API routes
validate_access_token_and_get_user
This function takes in the Authorization
HTTP header and verifies the request
was made by a valid user. It expects the header to be in the format
Bearer ACCESS_TOKEN
. If the Authorization HTTP header is malformed or doesn’t
contain a valid access token, an
UnauthorizedException
is thrown.
Otherwise, a User is returned.
auth_header = # get authorization header in the form `Bearer {TOKEN}`
try:
user = auth.validate_access_token_and_get_user(auth_header)
print("Logged in as", user.user_id)
except UnauthorizedException:
print("Invalid access token")
validate_access_token_and_get_user_with_org
This function will verify that a request was made by a valid user AND that user is in an organization.
Argument | Description |
---|---|
Authorization HTTP Header | It expects the header to be in the format Bearer ACCESS_TOKEN . If the Authorization HTTP header is malformed or doesn’t contain a valid access token, an UnauthorizedException is thrown. |
Required Org ID | A string representing the organization ID to check that the user is a member of. If the user is NOT a member of the specified organization, a ForbiddenException is thrown. |
The return value has a user
and a org_member_info
A user
returned by validate_access_token_and_get_user
and validate_access_token_and_get_user_with_org.
The id of the user
A dictionary of org ids to metadata about the org. Includes all orgs that the user is in
The original ID of the user, if the user was migrated from an external source
If someone on your team is impersonating another user, this will be set to the employee’s ID. By default, user impersonation is turned off and this will be None
org_member_info
returned by validate_access_token_and_get_user
and validate_access_token_and_get_user_with_org.
The id of the org
The name of the org
The user’s role within the organization. See Roles and Permissions for more details.
Returns True if the user’s role within the organization matches the role
passed in
Returns True if the user’s role within the organization is at least the role
passed in. If the hierarchy of roles is Owner => Admin => Member, specifying “Admin” will return True for Admins and Owners, but False for Members.
Return True if the user has a specific permission. The users’ permissions are derived from their role within this organization.
Return True if the user has all the specified permissions. The users’ permissions are derived from their role within this organization.
Roles and Permissions
A user has a Role within an organization. By default, the available roles are Owner, Admin, or Member, but these can be configured. These roles are also hierarchical, so Owner > Admin > Member.
Roles allow you to control what different users can do within your product. If you want to check a user’s role, you can use auth.validate_access_token_and_get_user_with_org_by_minimum_role or auth.validate_access_token_and_get_user_with_org_by_exact_role which will very the request was made by a valid user, that user is in the specified organization, AND that the user’s within the organization matches what was passed in.
Permissions are arbitrary strings associated with a role. For example, can_view_billing, ProductA::CanCreate, and ReadOnly are all valid permissions. The PropelAuth dashboard allows you to set up these permissions.
You can use auth.validate_access_token_and_get_user_with_org_by_permission or auth.validate_access_token_and_get_user_with_org_by_all_permissions to check for a given permission.
All of these functions, just like validate_access_token_and_get_user_with_org, will take in an authorization header and an organization ID. The last parameter is either a role, permission, or list of permissions depending on the function.

Migrate User from External Source
A similar function to Create User, but for cases where you already have a user stored in an external system. You can, for example, pass in a password hash for an existing user, and they will be able to login with their same password. It is also possible to provide an existing identifier, and we will store and return it along with our future identifiers, allowing you to link them.
# auth object comes from init_base_auth
auth.migrate_user_from_external_source(email, email_confirmed,
existing_user_id=None, existing_password_hash=None,

ask_user_to_update_password_on_login=False,
enabled=None, first_name=None, last_name=None, username=None)
The user’s email address
Whether the email address should start off as already confirmed. If false, the user is required to confirm the email address before they sign in.

and it is present everywhere user_id’s are (e.g. fetching user metadata or validating a user’s token).

(Optional) The user’s MFA secret, base32 encoded. If specified the user will have MFA enabled by default.

}
Create magic link
Creates a magic link that a user can use to log in. Use this API if you’d prefer to send the magic link to the customer yourself, otherwise, we have Create User which will email them directly.
# auth object comes from init_base_auth
auth.create_magic_link(email, redirect_to_url=None, expires_in_hours=None, create_new_user_if_one_doesnt_exist=None)
Argument | Description |
---|---|
The user’s email address | |
redirect_to_url | (Optional) Where to redirect the user after they login. If unspecified, will use the login redirect path specified in your dashboard. |
expires_in_hours | (Optional) How many hours should the link be valid for? |
create_new_user_if_one_doesnt_exist | (Optional) If true, this will create a new user if one matching the provided email address doesn’t exist. If false, the request will fail if no user with that email exists. Default is true. |
The user’s email address
(Optional) Where to redirect the user after they login. If unspecified, will use the login redirect path specified in your dashboard.
(Optional) How many hours should the link be valid for?
(Optional) If true, this will create a new user if one matching the provided email address doesn’t exist. If false, the request will fail if no user with that email exists. Default is true.
Successful response:
{
"url": "https://auth.yourdomain.com/..."
}
Create Access Token
Our frontend libraries allow you to get access tokens that can be sent to the backend. The backend is then responsible for verifying these tokens.
For testing purposes, you may want to create access tokens separately from the frontend and set a custom expiration time. With this API, you can create access tokens for users programmatically and set a custom expiration.
# auth object comes from init_base_auth
auth.create_access_token(user_id, duration_in_minutes)
The id of the user
How long the token is valid for, in minutes.
Successful response:
{
"access_token": "..."
}
