Marketo V3 Connections Overview
Create a Marketo connection to connect to Marketo so that the Secure Agent can read data from and write data to Marketo. You can specify the Marketo source and target in mappings, Mapping Configuration tasks, or Data Synchronization tasks.
You create a Marketo connection on the Connections page. Use the connection when you create a Data Synchronization task or a Mapping Configuration task.
