API (Application Programming Interface) has always been the most preferred means of integration between two systems. For instance, an HR software and payroll. This is most convenient when data needs to be exchanged every time a requirement arises. However, what if instant notifications need to be sent and received the very second an event is triggered? That’s precisely what a webhook does.

A webhook is an http call back that sends data to the third party system whenever an event is triggered. For example, when a travel expense record is approved, a webhook instantly notifies the accounting system by invoking its API to process the reimbursement. Alternatively, if a webhook isn’t used, the API  will only be called periodically (end of day, week, or month) to find out pending reimbursements and hence delay the payment process.

A Webhook is certainly a better way to integrate with third party systems and your own custom applications, ensuring data synchronization at all times. That’s why Zoho People has now adopted Webhooks!
