How to Add MailChimp app
When creating the Bot (or in the Apps tab), open the Apps drop-down menu, select “MailChimp” under “Add New App” and click on connect to continue.
In the pop-up window, Authorise access to your MailChimp account with your valid login and password and click on save button to save the app.
Resolving Authentication Errors
Sometimes you may see authentication errors like invalid API Key (screenshot below).
This might happen when you delete the Automate.io app from your MailChimp application under accounts sections
You may encounter these errors either while creating the Bot, or enabling the Bot or in the Bot activity.
To resolve this issue, you will need to re-connect your MailChimp app.
Go to Apps list, and hover on the MailChimp app, and click on the icon that says 're-connect the app'
A new pop-up window opens up, allowing you to re-authorize access to your MailChimp account. Finish the authorization and save the app.
Add to Automation Error
If you see an error like - subscriber not present in the List. Please do the following.
Note that an Automation in MailChimp is linked it a List. And the subscriber you wish to add to the Automation should be present in the SAME list.
So in your Bot, you need to add and an Action to add the subscriber to the List first, and then add to the Automation.
