Mailchimp + Zapier integration

Plandalf has no Zapier app. Mailchimp has native Plandalf steps and triggers, so you do not need Zapier for those. Zapier fits where Plandalf has nothing built in: Send Webhook can post a Plandalf event to a Zap's catch hook, and a Zap can post a Mailchimp event to a Plandalf catch URL.

1. Use the native Mailchimp steps first

   In Automation, Marketplace, connect Mailchimp. Build the tag and event steps for buyers in a sequence on Checkout Completed before adding anything else.

2. Create the Zap's catch hook

   In Zapier create a Zap with the Webhooks by Zapier trigger, Catch Hook, and copy the custom URL from its Test tab.

3. Post to it from Plandalf

   In your sequence add Send Webhook with that URL, POST, and a JSON payload with email, offer and total filled from trigger variables. Run the test so Zapier receives a sample.

4. Finish the Zap

   Add the Zapier action you need, mapping the fields from the caught request. Turn the Zap on.

5. Bring a Mailchimp event the other way

   Create a Plandalf sequence with the Webhook Trigger and copy its URL. In a second Zap, add a Mailchimp trigger and a Webhooks by Zapier POST action pointing at that URL.

6. Test both directions

   Send one real event each way and confirm the Events view in Plandalf and the Zap history both show it.

• Plandalf has no Zapier app, and the Zapier trigger and action are the generic Webhooks ones. Zapier lists Webhooks as available on its Professional, Team and Enterprise plans, so check your plan.
• Zapier answers 200 while a Zap is on and 404 when it is off or deleted, so a switched-off Zap makes the Send Webhook step show an error.
• A catch URL on either side is a secret address. Do not put it in public pages, and check fields in the payload before acting on them.
• The Mailchimp trigger already covers subscribe and unsubscribe, so a Zap that also watches those would run the sequence twice.
• Zapier's catch hook accepts POST, PUT or GET, but Plandalf's Send Webhook defaults to POST with JSON, which is the safest pairing.

Does Mailchimp integrate with Zapier through Plandalf?

Plandalf has no Zapier app. Mailchimp is native in Plandalf, and Zapier is an optional bridge through Send Webhook and the Webhook Trigger catch URL.

How do I connect Plandalf to Mailchimp with Zapier?

You usually do not need to, since Plandalf has Mailchimp steps. For other events, post from Send Webhook to a Zap's catch hook or from a Zap to a Plandalf catch URL.

Which Mailchimp events can reach Plandalf?

Contact Subscribed and Contact Unsubscribed natively. Through Zapier's Mailchimp app, triggers such as new or updated subscriber, new campaign, email opened and new order are listed.

Do I need a paid Zapier plan?

Zapier's help page lists Webhooks as a feature of its Professional, Team and Enterprise plans. Check its current plans before building this.
