dayforce-client

dayforce-client is a python SDK for interfacing with the Dayforce REST API and SFTP server.

Installation

$ pip3 install dayforce-client

Basic Usage (Rest API)

The main interface to the Dayforce REST API is the Dayforce class. You can instantiate the Dayforce class by supplying a few authentication and configuration arguments:

import os

from dayforce_client.client import Dayforce

DAYFORCE_USERNAME = os.environ["DAYFORCE_USERNAME"]
DAYFORCE_PASSWORD = os.environ["DAYFORCE_PASSWORD"]
DAYFORCE_CLIENT_NAMESPACE = os.environ["DAYFORCE_CLIENT_NAMESPACE"]

df = Dayforce(username=DAYFORCE_USERNAME,
              password=DAYFORCE_PASSWORD,
              client_namespace=DAYFORCE_CLIENT_NAMESPACE)

All get_ methods on the Dayforce class will return a DayforceReponse object. A DayforceReponse object contains the Dayforce instance used to make the call, the parameters used in the request, and the response received from the API:

resp = df.get_employee_details(xrefcode='12345')
print(resp.client)
print(type(resp.client))
print(resp.params)
print(type(resp.resp))
print(resp.resp.url)
print(resp.resp.status_code)
print(resp.resp.ok)
print(resp.resp.elapsed)

...


Dayforce(username='your-username', client_namespace='your-client-namespace', dayforce_release=57, api_version='V1', url='https://usr57-services.dayforcehcm.com/Api/your-client-namespace/V1')
<class 'dayforce_client.client.Dayforce'>
{}
<class 'requests.models.Response'>
https://usr57-services.dayforcehcm.com/Api/your-client-namespace/V1/Employees/12345
200
True
0:00:00.550066

Query Parameters

Certain methods also accept keyword arguments that will be used as query parameters for the request:

resp = df.get_employee_details(xrefcode='12345', expand='WorkAssignments')
print(resp.resp.url)

Output:

https://usr57-services.dayforcehcm.com/Api/your-client-namespace/V1/Employees/12345?expand=WorkAssignments

Accessing Response Content

Response contents can accessed using .get() syntax:

resp = df.get_employee_details(xrefcode='12345')
print(resp.get("Data"))

Pagination

Responses can also optionally be paginated using iteration syntax:

for page in df.get_employee_raw_punches():
  for raw_punch in page.get("Data"):
    print(raw_punch)

Yielding Resource Records

Optionally, you can use the DayforceResponse .yield_records() method to handle response pagination and yieliding resource records. The method will paginate the response and iterate through response content to yield single resource records for the given resource and the corresponding DayforceResponse instance:

for page, employee in df.get_employees().yield_records():
    print(employee)
    print(page)

...

{'XRefCode': '12345'}
DayforceResponse(client=Dayforce(username='your-username', client_namespace='your-client-namespace', dayforce_release=57, api_version='V1', url='https://usr57-services.dayforcehcm.com/Api/your-client-namespace/V1'), params={}, resp=<Response [200]>)
{'XRefCode': '67891'}
DayforceResponse(client=Dayforce(username='your-username', client_namespace='your-client-namespace', dayforce_release=57, api_version='V1', url='https://usr57-services.dayforcehcm.com/Api/your-client-namespace/V1'), params={}, resp=<Response [200]>)

Basic Usage (SFTP client)

client = DayforceSFTP(
  hostname='foo01.dayforcehcm.com',
  username='mycompany',
  password='sekret',
  disable_host_key_checking=True,
)
client.connect()

Using disable_host_key_checking is discouraged, however. Instead, use ssh-keyscan to retrieve a known-good key (better yet, see if Dayforce will provide it to you!) and pass it in to the construtor.

ssh-keyscan foo01.dayforcehcm.com
# foo01.dayforcehcm.com:22 SSH-2.0-9.99 FlowSsh: Bitvise SSH Server (WinSSHD)
foo01.dayforcehcm.com ssh-rsa AAAAB3...snip...XYZ

client = DayforceSFTP(
  hostname='foo01.dayforcehcm.com',
  username='mycompany',
  password='sekret',
  host_key='AAAAB3...snip...XYZ',
)
client.connect()

Batch Imports

Dayforce provides the ability to batch import data via SFTP. This client wraps up most of the business logic around this process, and exposes a simple, high-level API.

from dayforce import DayforceSFTP, ImportError, ImportPending

client = DayforceSFTP(hostname=...)
with client.connect():
  batch_token = client.put_import('./local/path/to/batch-20191225T000000.csv', type='KpiTargetImport')
  while True:
    try:
      client.raise_for_import_status(batch_token)
      print('batch import succeeded')
      break
    except ImportPending e:
      sleep 10
      continue
    except ImportError e:
      print('batch import failed')
      break
