Click on Add New Connection and choose Mautic from the Available options in the dropdown.

Add Mautic Connection

Now here you will need API URL, which is going to be your Mautic Instance URL. And we need to generate the Keys for OAuth2.

Note: Please note that when Mautic API URL is mentioned, Ideally it is but in this case you only need to copy your Mautic URL which should be No need to add /api at the end.

Creating API credentials in Mautic

Go to your Mautic and log in into it to reach Dashboard.

Click on Settings > API Credentials.

mautic api credentials menu

You will see option to create new API credentials for Mautic, here you need to click New button.

In the auth type choose OAuth2.

In the name field give it a name of your choice.

URL to copy

In the Redirect URI field you need to copy the url of your thrive themes add connection page and append &api=mautic to it. So for example if the page URL looks like ‘’ then you need to copy paste it and then add ‘&api=mautic’ to it so the final URL will look like ‘’.

Credentials add screen

So once done click on ‘Save and close’ button on top left, this will generate the credentials for you.

Connection details added

Finally click on Connect, this will take you for the Authentication and you will be asked to login in and authorize your connection with Mautic.

Connection Ready

Once done your connection is ready and Mautic is connected with Thrive themes, and you will be able to integrate the Thrive themes leads with Mautic. Basically you will be able to create contacts in Mautic when a new lead is generated with Thrive themes.

Please note that you will need to choose this integration at the time when you are choosing the form actions.

Important part here is to keep in mind that,

  1. When you add API URL in the connection config form you don’t need to add ‘/api’ at the end of your Mautic URL.
  2. When you copy the URL from WordPress to Mautic API Credentials page for Redirect URI you need to append ‘&api=mautic’ at the end of it.

With the hopes that it will help you configure and connect your thrive themes with mautic. Here’s a complete connection Video from my Youtube channel for you.
