Ever need a form from one Mautic instance copied to another Mautic instance? Me too. So I solved the problem; here’s the solution (in [n8n](https://epl.ink/n8n-openai)).

## Who uses this?

Anyone running multiple Mautic instances and wants to duplicate a form into a different Mautic instance.

## How does it work?

In n8n (requires [n8n](https://epl.ink/n8n-openai), an entirely different platform from Mautic), a GET request is made to the API of the Mautic instance where the form already exists (source). Following, a Code node isolates all essential fields. The a POST request is made to the Mautic instance where you need the form duplicated (target).

Like this:

SOURCE MAUTIC Get Form → CODE NODE Build Request Body → TARGET MAUTIC Create New Form

## How to use?

Get [n8n](https://epl.ink/n8n-openai).

Copy-paste this JSON into a blank n8n workflow:

```auto

Replace URLs for the GET and POST requests.

Fill in your Mautic creds for both API requests.

This is a really practical solution for anyone juggling multiple Mautic instances. Using n8n as the middle layer makes a lot of sense, especially since it lets you clean up all the Mautic-specific metadata before recreating the form. The workflow is easy to follow, and the Code node does the heavy lifting in a transparent way. It’s also nice that it avoids manual exports or fragile SQL hacks. For teams managing many environments, this feels like a clean, repeatable approach that could save a lot of time.
