Mailchimp Subscribe Event Catcher

This n8n workflow is designed to automatically catch and process new subscriber events from Mailchimp. It acts as a webhook listener, waiting for Mailchimp to notify it whenever a new user subscribes to one of your audiences.

What it does

1. Listens for Mailchimp Subscribe Events: The workflow starts by exposing a webhook URL that Mailchimp can call. When a new subscriber is added to a configured Mailchimp audience, Mailchimp sends a notification to this URL.

Prerequisites/Requirements

• n8n Instance: A running instance of n8n to host this workflow.
• Mailchimp Account: An active Mailchimp account with at least one audience configured.
• Mailchimp Webhook: You will need to configure a webhook in your Mailchimp audience settings to send "subscribe" events to the n8n webhook URL generated by this workflow.

Setup/Usage

1. Import the workflow: Import the provided JSON into your n8n instance.
2. Configure the Mailchimp Trigger:
   • Click on the "Mailchimp Trigger" node.
   • The node will automatically generate a unique webhook URL. Copy this URL.
3. Set up Mailchimp Webhook:
   • Log in to your Mailchimp account.
   • Navigate to the audience you want to monitor.
   • Go to Settings > Webhooks.
   • Click "Create New Webhook".
   • Paste the copied n8n webhook URL into the "Callback URL" field.
   • Ensure that "Subscribes" is checked under "What type of updates should we send?".
   • Click "Save".
4. Activate the workflow: Save and activate the workflow in n8n.

Now, whenever a new user subscribes to your configured Mailchimp audience, this n8n workflow will be triggered, and you can add subsequent nodes to process this event further (e.g., send a Slack notification, add to a CRM, update a Google Sheet, etc.).
