Managing event attendees across multiple platforms can create operational friction for sales and marketing teams. When your events are hosted in Zoho Backstage but customer data lives in Zoho CRM, switching between systems slows productivity and increases the risk of data inconsistency.
This is where a custom Zoho CRM Widget becomes a powerful solution.
In this guide, you’ll learn how to build a Zoho CRM widget that integrates with Zoho Backstage, enabling users to:
- View live event data
- Register attendees
- Remove attendees – all directly from the Contact Details page in Zoho CRM
