Earlier in this course
in a separate course section
where we added payments to the online shop,
I introduced you to third party services and APIs.
In this course section, we are going to explore how
we can build our own APIs and services.
We're going to explore a specific concept called REST APIs,
and what that stands for and what it is.
And most importantly, of course, you will understand
why you might wanna build such APIs and services,
which different use cases you would have for that,
and, of course, how you build such APIs and services.
And, of course, we are also going to dive into
some concrete examples throughout this section.
Now, specifically, we are going to start
by having a brief look at why
we might wanna build custom services and APIs,
before we then have a look at REST APIs
and understand what that is specifically,
and how we would build such a REST API,
before we then, of course, do exactly that
and we dive into a concrete example
or actually multiple examples where we build such a REST API
ideal for a custom service, as you will see,
from the ground up, step by step.
