How to successfully load bulk contacts into constant contact API via python? - python-2.7

Question

I need to bulk load contacts to particular list via Constant Contact API (http://developer.constantcontact.com/docs/contacts-api/contacts-collection.html?method=POST).
I can successfully add contacts using the same JSON string as below into the following API GUI website(https://constantcontact.mashery.com/io-docs (find Tab POST 'add contact' to collection):
update_contact = {"lists": [{"id": "1"}],"email_addresses": [{"email_address": "yasmin1.abob19955#gmail.com"}],"first_name": "Ronald","last_name": "Martone"}
However when I run the same JSON string in my python code I get error 400 with the error message from my response object as the following:
[{"error_key":"query.param.invalid","error_message":"The query parameter first_name is not supported."},
{"error_key":"query.param.invalid","error_message":"The query parameter last_name is not supported."},{"error_key":"query.param.invalid","error_message":"The query parameter lists is not supported."},{"error_key":"query.param.invalid","error_message":"The query parameter email_addresses is not supported."}]
How can two of the same API calls produce different results?and how do I get my python code to work?
code:
import requests
headers = {
'Authorization': 'Bearer X',
'X-Originating-Ip': '1',
'Content-Type': 'application/json'
}
update_contact = {"lists": [{"id": "1"}],"email_addresses": [{"email_address": "yasmin1.abob19955#gmail.com"}],"first_name": "Ronald","last_name": "Martone"}
r_2 = requests.post('https://api.constantcontact.com/v2/contacts?action_by=ACTION_BY_OWNER&api_key=x', headers=headers ,params = update_contact)
print(r_2.text)

You will need to change params to data
r_2 = requests.post('https://api.constantcontact.com/v2/contacts?action_by=ACTION_BY_OWNER&api_key=x', headers=headers ,data = update_contact)
Additionally, you can use a multipart endpoint to upload contacts as well. I have found this to be very easy especially if your contacts are in a csv file.
A sample code would look like this:
import requests as r
import csv
from datetime import datetime
url = 'https://api.constantcontact.com/v2/activities/addcontacts?api_key=<your_api_key>'
headers = {'Authorization': 'Bearer <access_token>',
'X-Originating-Ip': '<ip>',
'content-type': 'multipart/form-data'}
files = {'file_name': 'Book1.csv',
'data': ('Book1.csv', open('Book1.csv', 'rb'),
'application/vnd.ms-excel', {'Expires': '0'}),
'lists':('<insert_listIds_seperated_by_commas>')}
response = r.post(url, headers=headers, files=files)
with open('CC_Upload_Response_Data.csv', 'a', newline='') as f:
writer = csv.writer(f)
time_stamp = datetime.now().strftime('%m-%d-%Y %H:%M')
row = [response, response.text, time_stamp]
writer.writerow(row)
The headers of your csv file need to be like so: "First Name" "Last Name" "Email Address" "Custom Field 1" "Custom Field 2" and so on. You can find a complete list of column names here: http://developer.constantcontact.com/docs/bulk_activities_api/bulk-activities-import-contacts.html
The csv file that this code appends acts like a log if you are going to schedule you .py file to run nightly. The log records the response code, response text and adds a timestamp.
Mess around with it a little and get it the way you like.
