Set up a webhook in Mailchimp
Overview
The Cin7 Omni webhook allows Cin7 Omni to receive unsubscribe and subscribe events as they happen in real-time. There are two steps to setting this up: Copying the webhook from Cin7 Omni, and adding it to your Mailchimp account.
Mailchimp will not show as an integration on your main dashboard.
Set up a webhook
To set up a webhook, first retrieve the URL from Cin7 Omni:
While logged in as an Administrator, select your username in the top right corner.
Select Settings.
From the integrations menu, select Mailchimp.
Copy the URL from the WebHook box to the clipboard.
Next, add the copied webhook to your Mailchimp Account:
From the lists page, select Settings and then select Webhooks.
Select Create New Webhook.
In the Callback URL field, paste the webhook you copied from Cin7 Omni.
Select Subscribes and Unsubscribes from the list of events.
Select Save.
