The update process is done in bulk and is limited by the file size of the bulk upload. Openprise uses approximately 1 API call per 300 records updated. If you are concerned about using too many API calls for your updates you can:
- Establish an API Quota to make sure Openprise limits the number of API calls used per day. Go to Administration > System Settings > Quota to define a Quota for Marketo, or
- Use filters to limit the number of updates done during one job run.
