Onfido Python Client Library

onfido-python on PyPI

Version 2.3.0

The official wrapper for Onfido's API. Refer to the full API documentation for details of expected requests and responses for all resources.

This version uses Onfido API v3.4. Refer to our API versioning guide for details of which client library versions use which versions of the API.

This project supersedes the automatically generated api-python-client library (onfido in PyPI).


pip install onfido-python

⚠️ Having the old onfido package installed at the same time will cause errors.

Getting started

Make API calls by using an instance of the Api class and providing your API token:

import onfido

api = onfido.Api("<YOUR_API_TOKEN>")


Set the region in the API instance using the region parameter, which takes a value from the Region enum (currently Region.EU, Region.US or Region.CA).

For example, to specify the EU region:

import onfido
from onfido.regions import Region

api = onfido.Api("<YOUR_API_TOKEN>", region=Region.EU)

region does not take a default parameter. Failure to pass a correct region will raise an OnfidoRegionError.

See for more information about our supported regions at a given time.


You can optionally set a global timeout for all requests in the API constructor. This takes a floating number input and each whole integer increment corresponds to a second.

For example, to set a timeout of 1 second:

api = onfido.Api("<YOUR_API_TOKEN>", timeout=1)

The default value for timeout is None, meaning no timeout will be set on the client side.

Response format

The Python library will return JSON requests directly from the API. Each request corresponds to a resource.

All resources share the same interface when making API calls. For example, use .create to create a resource, .find to find one, and .all to fetch all resources.

For example, to create an applicant:

applicant_details = {
  'first_name': 'Jane',
  'last_name': 'Doe',
  'dob': '1984-01-01',
  'address': {
    'street': 'Second Street',
    'town': 'London',
    'postcode': 'S2 2DF',
    'country': 'GBR'
  'location': {
    'ip_address': '',
    'country_of_residence': 'GBR'

  'id': '<APPLICANT_ID>',
  'created_at': '2019-10-09T16:52:42Z',
  'sandbox': True,
  'first_name': 'Jane',
  'last_name': 'Doe',
  'email': None,
  'dob': '1990-01-01',
  'delete_at': None,
  'href': '/v3.1/applicants/<APPLICANT_ID>',
  'id_numbers': [],
  'address': {
    'flat_number': None,
    'building_number': None,
    'building_name': None,
    'street': 'Second Street',
    'sub_street': None,
    'town': 'London',
    'state': None,
    'postcode': 'S2 2DF',
    'country': 'GBR',
    'line1': None,
    'line2': None,
    'line3': None
  'phone_number': None,
  'location': {
    'ip_address': '',
    'country_of_residence': 'GBR'

See,-response-format for more information.
