When updating program status does it cost API calls?

[DhananjayaW]

Hi all,
I have synced my Email program to a SFDC campaign. When I update the program status i.e. Sent, Bounced, Opened, Clicked does it cost me API calls?
My target had 130k records and our API call limit per day is 50k. I'm worried that updating the synced program status is going to run us out of our daily API call limit.
Any idea?
Also, if I don't sync the program and used "Add to SFDC Campaign" activity to update the campaign member status, does that behave differently and cost us API calls to SFDC?

Sync lead to SFDC” is a 1:1 for API calls  and Add lead to SFDC Campaign” is a 1:1 API Calls too.

Your Salesforce API call limit is only 50K? What version of Salesforce do you have, and how many users?
