In detail
REST APIs organise data as resources (customers, orders) accessed through URLs with methods such as GET, POST, PUT and DELETE. They are simple to consume from web and mobile apps and from other systems.
Most integrations between business systems are built on REST APIs.
How this relates to our work
REST API comes up most often in our custom solutions work. Business automation, internal systems and integrations for processes that off-the-shelf software does not fit.
