We recently completed our final deployment of our Spring Update which introduced new features and enhancements for our customers as well as a few changes to the API.
Based on the feedback we received about the changes to the API in this update, we will publish upcoming changes to the API with as much advance notice as possible.
API Changes in R30:
DataService & Contact Service: Custom Fields are now case-sensitive.
Custom Field Validation: Custom Fields are now validated before using it in the query.
APIEmailService.sendEmail: Will return false if one or more email addresses are unable to receive marketing emails (opt-out, not marketable).
