We define system integrations is the use of built in tools to get two pieces of software talking to each other. They are not custom-built integrations, they are pre-made and come with the software. They usually require expertise to establish, activate and manage.
We set integrations up frequently and thus have deep knowledge of how they work. We know what settings are available and what they mean. We also know what to watch out for and avoid the traps that may exist for inexperienced users.
