FastAPI Library Reference

Installation

pip

$ pip install propelauth_fastapi

Initialize

init_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 require_user, optional_user, or require_org_member.

from propelauth_fastapi import init_auth

auth = init_auth("YOUR_AUTH_URL", "YOUR_API_KEY")

Protect API routes

require_user

A dependency that will verify the request was made by a valid user. If a valid access token is provided, it will return that user’s information (including fields like a user_id). If not, the request is rejected with a 401 status code.

from fastapi import FastAPI, Depends
from propelauth_fastapi import init_auth, User

app = FastAPI()
auth = init_auth("AUTH_URL", "API_KEY")

@app.get("/")
async def root(current_user: User = Depends(auth.require_user)):
    return {"message": f"Hello {current_user.user_id}"}

optional_user

Similar to require_user, except if an access token is missing or invalid, the request is allowed to continue, but the dependency will be None.

from typing import Optional

from fastapi import FastAPI, Depends
from propelauth_fastapi import init_auth, User

app = FastAPI()
auth = init_auth("AUTH_URL", "API_KEY")

@app.get("/api/whoami_optional")
async def whoami_optional(current_user: Optional[User] = Depends(auth.optional_user)):
    if current_user:
        return {"user_id": current_user.user_id}
    return {}

require_org_member

A function that will verify that a user belongs to a specific organization.

from fastapi import FastAPI, Depends
from propelauth_fastapi import init_auth, User

app = FastAPI()
auth = init_auth("AUTH_URL", "API_KEY")

@app.get("/api/org/{org_id}/check")
async def admin_only(org_id: str, current_user: User = Depends(auth.require_user)):
    org = auth.require_org_member(current_user, org_id)
    return {"message": f"You are in {org.org_name}"}

current_user

The result of require_user

required_org_id

The id of an organization. This function will check that the current user is a member of this org. Typically, this is passed in from the frontend as a query or path parameter.

Specifically, it will:

Check that a valid access token was provided. If not, the request is rejected with a 403 status code.
Return the organization’s information for this user.

The returned organization is an OrgMemberInfo

User

A user returned by require_user or optional_user.

user_id

The id of the user

org_id_to_org_member_info

A dictionary of org ids to metadata about the org. Includes all orgs that the user is in

legacy_user_id

The original ID of the user, if the user was migrated from an external source

impersonator_user_id

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

OrgMemberInfo

The values of org_id_to_org_member_info are OrgMemberInfo‘s.

org_id

str

The id of the org

org_name

str

The name of the org

user_assigned_role

str

The user’s role within the organization. See Roles and Permissions for more details.

user_is_role(role)

Returns True if the user’s role within the organization matches the role passed in

user_is_at_least_role(role)

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.

user_has_permission(permission)

Return True if the user has a specific permission. The users’ permissions are derived from their role within this organization.

user_has_all_permissions(permissions)

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 require_org_member_with_minimum_role or require_org_member_with_exact_role.

## Assuming a Role structure of Owner => Admin => Member

@app.get("/api/org/{org_id}/admin_only")
async def admin_only(org_id: str, current_user: User = Depends(auth.require_user)):
    org = auth.require_org_member_with_exact_role(current_user, org_id, "Admin")
    return {"message": f"You are an Admin of {org.org_name}"}

@app.get("/api/org/{org_id}/admin_or_owner")
async def admin_or_owner(org_id: str, current_user: User = Depends(auth.require_user)):
    org = auth.require_org_member_with_minimum_role(current_user, org_id, "Admin")
    return {"message": f"You are an Admin or Owner of {org.org_name}"}

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 require_org_member_with_permission or require_org_member_with_all_permissions to check for a given permission.

@app.get("/api/org/{org_id}/billing")
async def billing(org_id: str, current_user: User = Depends(auth.require_user)):
    org = auth.require_org_member_with_permission(current_user, org_id, "can_view_billing")
    pass

Usage with API docs

FastAPIs built in documentation will automatically add this button when you are using either require_user or optional_user.

API docs authorize button

You can obtain an access token either from the frontend or by navigating to ${YOUR_AUTH_URL}/api/v1/refresh_token.

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,

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
email	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.

str

The user’s email address

redirect_to_url

str

(Optional) Where to redirect the user after they login. If unspecified, will use the login redirect path specified in your dashboard.

expires_in_hours

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)

user_id

str

The id of the user

duration_in_minutes

int

How long the token is valid for, in minutes.

Successful response:

{

orgId

str

orgId

str

The org’s ID

Returns True if successful, meaning the organization can no longer set up SAML connections.

# auth object comes from init_base_auth
# Returns true if it was successful, false if the organization was not found
