n8n Integration with Zoho Calendar

n8n is a powerful, open-source workflow automation software that allows you to connect different apps and automate tasks with ease. Its intuitive visual editor and drag-and-drop interface makes building complex workflows accessible to everyone.

The core functionality of n8n is to build workflows and integrations with various applications. It offers customizable triggers, actions, and logic, with features like self-hosting, error handling, and scheduling. With its visual interface, n8n enables both technical and non-technical users to create complex automations effortlessly.

n8n's integration with Zoho Calendar helps you to stay on track with your schedules, meetings, and events. You can custom-design your workflow by applying triggers and actions to automate your business processes.

Triggers 

Triggers are events that start a workflow. They are executed when a specific set of conditions are met. For example, you can set up Zoho Calendar to send updates or check for new events regularly, and n8n can trigger a workflow whenever an event is added or updated. 

The supported triggers are:

• Event Created - Triggers when an event is created.
• Event Deleted - Triggers when an event is deleted.
• Event Updated - Triggers when an event is updated.

Actions

Actions are the tasks or operations that a node can perform within a workflow. For example, when an event is added or updated in Zoho Calendar, it triggers an action in n8n, such as sending email notifications or creating tasks in other applications.

The supported actions are:

• Create an event - Creates an event in the specified calendar.
• Delete an event - Deletes an event from the specified calendar.
• Quick add an event - Creates an event from a piece of text.
• Update an event - Updates an event in the specified calendar.
