A python library which implements the complete functionality of v3 of the CreateSend API.


pip install -e git+


Basic usage

Retrieve a list of all your clients.

from createsend import *

CreateSend.api_key = 'your_api_key'

cs = CreateSend()
clients = cs.clients()

for c in clients:
  print "%s: %s" % (c.ClientID, c.Name)

Results in:

4a397ccaaa55eb4e6aa1221e1e2d7122: Client One
a206def0582eec7dae47d937a4109cb2: Client Two

Handling errors

If the createsend API returns an error, an exception will be thrown. For example, if you attempt to create a campaign and enter empty values for subject etc:

from createsend import *

CreateSend.api_key = 'your_api_key'

  cl = Client("4a397ccaaa55eb4e6aa1221e1e2d7122")
  id = Campaign().create(cl.client_id, "", "", "", "", "", "", "", [], [])
  print "New campaign ID: %s" % id
except BadRequest as br:
  print "Bad request error: %s" % br
  print "Error Code:    %s" %
  print "Error Message: %s" %
except Exception as e:
  print "Error: %s" % e

Results in:

Bad request error: The CreateSend API responded with the following error - 304: Campaign Subject Required
Error Code:    304
Error Message: Campaign Subject Required

Expected input and output

The best way of finding out the expected input and output of a particular method in a particular class is to use the unit tests as a reference.

For example, if you wanted to find out how to call the Subscriber.add() method, you would look at the file test/

def test_add_with_custom_fields(self):
  self.subscriber.stub_request("subscribers/%s.json" % self.list_id, "add_subscriber.json")
  custom_fields = [ { "Key": 'website', "Value": '' } ]
  email_address = self.subscriber.add(self.list_id, "", "Subscriber", custom_fields, True)
  self.assertEquals(email_address, "")
