Question 1

How do I message new Mailchimp subscribers on WhatsApp?

Accepted Answer

Use a Mailchimp recent-activity step or list webhook to detect a new member, then a WhatsApp Send a Pre-Approved Template Message operation, since WhatsApp requires approved templates for messages outside a 24-hour session.

Question 2

Can WhatsApp conversations build my Mailchimp list?

Accepted Answer

Yes. Use the WhatsApp incoming-message webhook to capture the sender, then a Mailchimp Add or Update a List Member step. Because Mailchimp keys on email, collect an email in the chat flow before adding the subscriber.

Question 3

Why do I need WhatsApp templates?

Accepted Answer

WhatsApp Business only allows free-form messages within a 24-hour window after the user messages you. Outside that window you must use the Send a Pre-Approved Template Message operation with a template approved in your WhatsApp Business account.

Question 4

What credentials are needed?

Accepted Answer

WhatsApp connects through the Cloud API with a phone number ID and access token, and Mailchimp uses an API key. Add each credential once on its node.
