What is Process Builder in Salesforce
Process Builder :
Process Builder in Salesforce is a powerful automation tool that allows you to automate business processes with a point-and-click interface, without the need for code.
It provides more complex and more advanced alternative to workflow rules, enabling users to create multiple actions and conditions based on various criteria.
Though salesforce recommends developers to user Flow Builder, but Process Builder can also help you automate your business processes and give you a graphical representation as you build it.
