Wrong Datacenter Invalid Key Error

[Max Keeler]

Hello,

I am intermittently receiving this error:

Invalid Mailchimp API Key: ### . You are accessing the wrong datacenter - your client library may not properly support our datacenter mapping scheme.

Interestingly, when I create a new api key and configure my code to use it, it works fine, for a while, and then I get the error again.  If I switch back to the original key, it works again!  For a while, and then breaks again.

One thing to note is that the application (which is synchronizing lists) is accessing multiple accounts with different keys.  It almost seems as though a key is disabled if there is some sort of activity that flags irregular behavior or something.

I'm using the latest MailChimp python package.

Any ideas?

Thanks,

Max

Hey Max,

Sounds like the URL to hit the API is being cached statically or in a class instance variable that's being reused and not properly rebuilt on every access of the API with a different key.  I'd need to see all of the code to know if that's the deal or not, though.  You could try making sure you re-initialize the object you are calling for API access on all accesses for a different user / API key and see if that clears it up.

Eirc,

Thanks for the reply, much appricated.  I believe in all cases I'm initializing a new object inside the function, like so:

def find_last_mailchimp_sub_date(mailchimp_list_id, api_key):
    mc = mailchimp.Mailchimp(apikey=api_key)
    members = mc.lists.members(id=mailchimp_list_id, status='subscribed',
                               opts={'sort_field': 'last_update_time', 'sort_dir': 'DESC'})


    date = members['data'][0]['timestamp']
    return date

It's definitely possible that something is getting cached though, I'll look into that more.

I've found the issue here, it appears that my version of the mailchimp python library (2.0.7) sets a global variable (ROOT) when creating the api post url.  This global variable seems to be set across instances.  Here's the line:

global ROOT
ROOT = ROOT.replace('https://api.', 'https://'+dc+'.api.')

But since root is already set to https://us3.api... the replace for the new datacenter doesn't work.

Something like this should fix it:

ROOT = re.sub(r'.*api', 'https://' + dc + '.api', ROOT)

I found the same thing.

It would be nice if the official client were fixed. In the meantime I rolled my own patch:

pip install -U -e git+https://bitbucket.org/yannkerherve/mailchimp-...@2.0.7-dcfix#egg=mailchimp
