If you want to integrate with Marketo via the ReST API, you’ll want to create a custom service. Here’s how.
Admin Permissions Required
You can’t create a custom service if you have the Spark level of Marketo.
Go to Admin and click LaunchPoint.
Under New, click New Service.
Enter a Display Name for the service. Select the API Only User previously created.
Notice that we already have native integration for popular webinar services.
Click Create.
Oh yeah! The service is now created, let’s go ahead and get all the credentials to provide for access.
Go to Admin and click LaunchPoint.
Click View Details for the custom LaunchPoint service created above.
Click Get Token.
Provide the Client Id, Client Secret, Authorized User, and Token to the person in charge of establishing the connection.
