Now, when we did this call here, we did this post. We passed some data that was in the body. It created this entity over here and everything worked.

So what did FastAPI do? It said "great, everything worked. 200 ok". But let's drop over on our httpstatuses.com again
0:18
and see about these success codes. So Okay, well, that's kind of the most generic term. And here's a representation of the resource.

We actually did give that back, so it's kind of okay. But what would make more sense would be created. Over here, we're creating a new thing,
0:34
we've accepted their data. It was all good. And we could either give them a location where it was created or something that describes
0:42
it. And what we're doing to describe it here is this is you know, theoretically an ID You could do a lookup on in a database or some

other API right? That's the idea, we're not fully fledged in this out. But a 201 created makes a lot more sense than 200.

So does that mean we've got to go write more complicated code instead of just doing this?

We've got a create a response and set all the information about it? No. Just like this little name up here, we could just say "status code equals 201".

So if everything goes okay, that's what's getting submitted, or returned. Otherwise, it's whatever you explicitly set. So like we would up here,
1:16
you know, 400 or 500 or whatever. Let's just submit this again. Boom. Check it out. 201

created. The request has been fulfilled and resulted in a new resource being created. And guess what? That new resource was returned as well. Awesome.

Now we're playing nice with status codes.
