What is this?
The Mailchimp integration messages new subscribers on WhatsApp as soon as they join one of your Mailchimp audiences. Each connection watches one audience.What can I do here?
- Send a WhatsApp template when someone subscribes
- Connect several audiences, each with its own message
- See every request Mailchimp sent, including failures
- Have every request checked with Mailchimp’s own signature
How to use it
1
Open the Mailchimp page
Go to Integrations, click Mailchimp, then Connect.
2
Enter your Mailchimp details
- Paste your Mailchimp API key, which ends in your data centre such as
-us6(in Mailchimp under Profile → Extras → API keys). - Enter the audience name or ID, for example Newsletter.
3
Choose your messages
Pick the WhatsApp template to send for a new subscriber:
Leave an event empty to send nothing for it.
4
Set up and activate
Click Set up and activate. The platform registers the webhook with Mailchimp for you and creates a ready-made automation that sends the right template for each event. You can open that automation in the builder any time.
Things to know
- The customer’s phone number comes from the audience’s PHONE field, so your signup form must ask for it. Subscribers without a phone number can’t be messaged.
- Repeats are ignored. If Mailchimp sends the same event twice, the customer isn’t messaged twice.
- One connection per audience. To watch another audience, connect Mailchimp again with that audience’s name or ID.
Troubleshooting / Technical Notes
- Connecting fails. Check the details you entered and that they belong to the right Mailchimp account. The error from Mailchimp is shown on the page.
- No messages are sent. Check the connection shows Connected, a template is chosen for the event, and the template is approved.
- A request shows as failed. Open the connection’s Activity tab and select the request to see the error and its raw body. A missing phone number is the most common cause.
- Webhooks look missing. On the connection page, click Verify on Mailchimp to check they are still registered. If any are missing, disconnect and reconnect to register them again.
- You rotated your key or token. Open the connection’s Settings tab and update the credentials.
