What You'll Need
Before starting, you'll need these 2 things from Mailchimp:
API Key — Your Mailchimp API key
Audience ID — The ID of the list to sync members to
Quick Setup
Step 1: Create a Mailchimp API Key

Troubleshooting
Events not appearing in Mailchimp?
Verify your API key has the correct permissions. The user who generated the key needs Manager-level access or higher.
Can't find Audience ID?
Go to Audience → All contacts → Settings → Audience name and defaults. The ID is a string of letters and numbers.
API key not working?
Make sure you copied the full key when it was generated. If lost, you'll need to create a new one.
API Key Security
Keep your API key safe:
Give each integration its own API key with a descriptive name
Never share API keys via email
If a key is compromised, revoke it immediately in Mailchimp
To revoke: Profile → Extras → API keys → click Revoke next to the key
