MailChimp. Error 401 (Unauthorized) when sending a request for adding a new list member

Question

Here is how I'm trying to send a request:

fetch('https://us17.api.mailchimp.com/3.0/lists/185415c92c/members', {
      method: 'POST',
      headers: {
        'Content-Type': 'application/json',
        'Authorization': 'anystring:8ec49e64f2041073d3fe56e0abc5fe5f-us17',
      },
      body: JSON.stringify({
        email_address: 'email@mail.ru',
        status: 'subscribed',
      }),
      mode: 'no-cors',
    })

And I get such error:

POST https://us17.api.mailchimp.com/3.0/lists/185415c92c/members 401 (Unauthorized)

What am I doing wrong?

Here is a website where you can test it http://silencer.website/stasyq/ — , Feb 21 '18 at 10:52
Yes, I tried to test it with postman and it works, but I don't know why it doesn't work on my website: http://prntscr.com/ihr3g9 http://prntscr.com/ihr38b http://prntscr.com/ihr3nt — , Feb 21 '18 at 11:07

The Authorization header contains both type and credentials, but in your code the header only contains the latter. The following should work:

Authorization: Basic <base64-encoding of anystring:8ec49e64f2041073d3fe56e0abc5fe5f-us17>

EDIT: The real reason why it wasn't working: CORS, which MailChimp understandably doesn't support.

I kept having the same issue, I checked my Key from MailChimp in my account setting. Under KEY, it said my key "was disabled" and under LABEL it said "posted in public, do not enable". Sometimes it's not our code, it's the key itself. Try checking the key you are currently using.
