MailChimp Integration
The MailChimp action sends form field values to MailChimp.
Create an API Key
- In Mailchimp, open your Profile, then Extras > API keys.
- Click Create A Key, give it a name such as
Breakdance forms, and click Generate Key. - Use Copy Key to Clipboard before clicking Done. The full key is shown only when it is created. See Mailchimp’s API key guide.
Save the Shared Key
- In WordPress, open Breakdance > Settings > API Keys.
- Paste the key into MailChimp API Key and click Save Changes.

Choose Default in the form to use this key, or Custom to enter a key for that form only.
Connect the Form
- Add the required form fields, including Email, then select MailChimp under Actions > Actions After Submission in the Content tab.
- Configure Use MailChimp API Key. Default uses site credentials; Custom uses credentials for this form. After correcting an invalid key, click Reload Key.
- Select the destination and map its fields to Form Field values, then save. Labels do not map automatically; destination choices depend on the connected account.
MailChimp Settings
Use MailChimp API Key, Audience, Double Opt-In, Field Mapping > Fields (Mailchimp Field → Form Field), and Audience Groups > Category / Group. Select the audience first. Double opt-in creates a pending subscription requiring confirmation.

Enable Run Action Conditionally and add Conditions to run this action only when all configured field comparisons match.
