How to Connect OptinMonster with Marketo

OptinMonster offers seamless integration with Marketo email marketing service. Connecting OptinMonster to your Marketo email list is very easy.

In this article, you’ll learn how to connect Marketo with OptinMonster.

Before You Start

Here are some things to know before you begin:

• Marketo integration is available with a Pro or higher subscription.
• As a best practice, we recommend you also connect your campaigns to Monster Leads as a backup.
• You can alternatively add a custom Marketo form to your campaign, to add extra fields or other custom functionality.

Connect Marketo

When you create a campaign in OptinMonster that you intend to collect leads with, you’ll want to integrate with one or more services to send those leads to.

To send leads to Marketo, follow these steps:

1. Navigate to the Integrations tab in the campaign builder.
   
2. Click Add New Integration.
   
3. Search for and select Marketo from the dropdown field.
4. Log into your Marketo account to obtain your API Key. To do this:
   1. In your Marketo account create a custom service.
   2. Once you have a custom service you will need to locate your Client ID and Client Secret.
      Navigate to the Admin page.
      
   3. Next, select LaunchPoint from the Integration section.
      
   4. Your custom services will be listed, select View Details on the custom service you’ve created for OptinMonster.
      
   5. Copy the Client ID and Client Secret from the lightbox.
      
5. Returning to the OptinMonster campaign builder, paste your Client ID  and Client Secret into the corresponding fields.
   
6. Copy the Marketo Subdomain from the REST API page of your Marketo account and paste it into the corresponding field in the OptinMonster campaign builder.
   
      Note: you only need to copy the first portion of the subdomain, do not include the beginning https:// or ending .mktorest.com/rest. Adding the full subdomain url will prevent OptinMonster from connecting to your Marketo account.
   
7. Next, select the Connect to Marketo button.
   
8. Once connected, select the Partition you wish to use.
   
9. Finally, select the List you would like to add leads to.
   
10. When you’re finished, click Save.

Troubleshooting

What if my Marketo plan doesn’t include API Integrations?

Some Marketo plans don’t allow you to use the Marketo API to add subscribers to your account.

However, you can still use our Custom HTML Optin Form integration option to add subscribers to your Marketo account without using their API.
