Current Limitation:

The Event API for Real-Time Marketing does not support submitting multiple attendees in a single POST request.

Currently, each attendee must be registered individually, requiring multiple POST calls. This creates inefficiencies and significant friction for scenarios such as paid registrations, where a registering multiple attendees for a paid event requires the submission of payment details multiple time.

Requested Enhancement:

• Allow batch submission of attendees using an array in a single POST request.
• Maintain backward compatibility with Outbound Marketing functionality, which already supports multi-attendee registration.
• Provide configuration options so admins can enable or disable batch submission based on organizational needs.

Business Impact:

• Improves efficiency for enterprise-scale events by reducing repetitive API calls.
• Enhances user experience for paid registrations, avoiding multiple payment entries.
• Aligns with customer expectations for modern API design and parity with Outbound Marketing.
• Reduces custom development and accelerates adoption of Real-Time Marketing features.
