Issue
I am using mailchimp3 in Python. I managed to make batch insertion of users using this function:
client = MailChimp(USERNAME, APIKEY)
def fill_list(list_id, subscribers_data):
data = {'operations': create_subscriptions_data(list_id, subscribers_data)}
client.batches.create(data)
def create_subscriptions_data(list_id, users_data):
return [{'method': 'PUT',
'path': 'lists/{}/members/{}'.format(list_id, str(md5(user['email_address'].encode('utf-8')))),
'body': json.dumps(user)} for user in users_data]
Here is how one user dict looks like:
{"email_address": "user@somemail.com", "status": "subscribed"}
Then I wanted to use similar method to unsubscribe list of users. To achieve that I tried to use the same logic, just to change the user objects. Now, I used this user format:
{"email_address": "user@somemail.com", "status": "unsubscribed"}
It doesn't update the subscribe status. When I deleted all users manually (using the web interface) and tried the same command I successfully created users with "status": "unsubscribed". I am wondering why this approach can't change the status? I tried also using POST instead of PUT, but it didn't work. Any idea what can be the issue?
I used this reference https://devs.mailchimp.com/blog/batch-operations-and-put-in-api-v3-0/ and it mentions that this approach should work fine for updates as well.
Thank you in advance!
Solution
Actually, I was using some wrong functions, so here is the fixed code. I also had some problems with the size of the batches. The maximum batch size is 500, so I did some splits of the data across several batches. Here is a simple code how the insertion should be done:
client = MailChimp(USERNAME, APIKEY)
def _update_list(list_id: str, members_data: list):
client.lists.update_members(list_id, {'members': members_data, 'update_existing': True})
Each member in members_data has data like this:
mailchimp_user = {
'email_address': user.email,
'status': user.subscription_status,
'merge_fields': {
'FNAME': user.first_name,
'LNAME': user.last_name
},
'interests': {}
}
And here comes the most important function:
def fill_in_multiple_batches(list_id, mailchimp_members):
step_size = 400
for i in range(0, len(mailchimp_members), step_size):
batch_start_idx = i
batch_end_idx = min(i + step_size, len(mailchimp_members))
this_batch_of_members = mailchimp_members[batch_start_idx:batch_end_idx]
client.lists.update_members(list_id, {'members': members_data, 'update_existing': True})
After that, in the main of the script:
if __name__ == '__main__':
fill_in_multiple_batches('your_list_id', your_data_list)
