A connector provides a ready-made or custom connection between an automation tool and a service or data source.
What does this mean in practice?
It exposes specific operations, such as reading information or creating an item. The existence of a connector does not mean that it supports every feature of the connected system.
Example use case
A workflow uses an email connection to detect a new request, then connects to a data store to save it.
Things to consider
Check supported operations, permissions and licensing requirements. Standard, premium and custom connectors can have different terms of use.
