Hello User,
Reltio is an API-first product, meaning that any access granted to a specific role applies to both the UI and the API. Currently, there is no out-of-the-box role that provides access solely to the Export Application. However, you can create a custom role, grant read-only access to the relevant entities and relationships using metadata security, and then allow access to the Export Application at the service level.
An example of a similar use case is provided in the following documentation link. Please take a look.

You can create the new custom role and select the necessary Export Service access from the User Management Console, as shown below.
