What Are Zoho CRM Extensions?
Zoho CRM extensions are custom applications that enhance CRM capabilities by adding new features, integrating third-party services, or automating workflows. Extensions can be built for internal use or published to the Zoho Marketplace for other users.
Widgets
Create custom UI components that display within Zoho CRM modules, providing contextual information and actions.
Integrations
Connect Zoho CRM with external applications, APIs, and services to synchronize data and automate processes.
Automation
Build serverless functions that execute custom business logic in response to CRM events and triggers.
Custom Modules
Extend CRM data models with custom modules, fields, and relationships tailored to your business needs.
Prerequisites
Before building Zoho CRM extensions, ensure you have the following:
