Emarsys Account Engagement API Monitoring/Calls

Hi Experts,

is there a way to monitor the API Calls that are made to Emarsys?

In Sales Cloud I have the OData API Monitor and can see the different calls that are made by Account Engagement Data Integration Service. It would be great to have the same possibility for Emarsys.

If that's not possible, does anyone know if Contacts are always updated with a full update?

So, if there's a field change for Contact Person in Sales Cloud (e.g. date of birth), then only the birthday field is updated in Emarsys or the whole contact with all fields that are available in Account Engagement Data Integration Service?

Kind Regards

Tobias
