1
00:00:00,090 --> 00:00:01,410
‫Okay, so now let's talk

2
00:00:01,410 --> 00:00:04,650
‫about the different API we can set up in the API Gateway.

3
00:00:04,650 --> 00:00:05,610
‫So far in this course,

4
00:00:05,610 --> 00:00:08,400
‫we've been using the REST API, but there's two other kinds.

5
00:00:08,400 --> 00:00:10,860
‫There's the HTTP API, and the WebSocket.

6
00:00:10,860 --> 00:00:13,110
‫And I will just describe at a high level what they are.

7
00:00:13,110 --> 00:00:14,880
‫I don't think they come up in the exam just yet,

8
00:00:14,880 --> 00:00:18,510
‫maybe WebSocket, but just, again, at a high level.

9
00:00:18,510 --> 00:00:22,620
‫So, the first is HTTP API, and they're low latency,

10
00:00:22,620 --> 00:00:26,610
‫cost effective AWS Lambda proxy, HTTP proxy API,

11
00:00:26,610 --> 00:00:28,050
‫and private integration.

12
00:00:28,050 --> 00:00:30,390
‫So, as you can see, it's all proxy.

13
00:00:30,390 --> 00:00:33,270
‫There is no data mapping available to us.

14
00:00:33,270 --> 00:00:36,060
‫And it supports only a few kind of authorizations.

15
00:00:36,060 --> 00:00:38,820
‫So, OIDC, and Oauth 2.0.

16
00:00:38,820 --> 00:00:41,280
‫And there's also built-in support for CORS,

17
00:00:41,280 --> 00:00:44,190
‫but you won't find any usage plan, or API keys.

18
00:00:44,190 --> 00:00:47,490
‫So, they're a very low cost alternative to the API Gateway.

19
00:00:47,490 --> 00:00:49,770
‫They're newer, they're horribly named,

20
00:00:49,770 --> 00:00:51,480
‫they're just more simple.

21
00:00:51,480 --> 00:00:53,850
‫And the REST API has all the features

22
00:00:53,850 --> 00:00:54,930
‫we've seen in this course,

23
00:00:54,930 --> 00:00:58,680
‫except that Native OpenID Connect, Oauth 2.0.

24
00:00:58,680 --> 00:01:01,020
‫And so, you can find a link highlighting the differences

25
00:01:01,020 --> 00:01:03,150
‫between HTTP and REST API.

26
00:01:03,150 --> 00:01:06,150
‫But what you have to remember at a high level for the exam,

27
00:01:06,150 --> 00:01:09,000
‫is that HTTP API's are going to be much cheaper

28
00:01:09,000 --> 00:01:10,920
‫than REST APIs.

29
00:01:10,920 --> 00:01:13,560
‫And they have a slight difference in terms of support.

30
00:01:13,560 --> 00:01:16,620
‫For example, REST API supports resource policies,

31
00:01:16,620 --> 00:01:18,540
‫whereas HTTP API's don't.

32
00:01:18,540 --> 00:01:20,010
‫All right, so that's it.

33
00:01:20,010 --> 00:01:20,910
‫I hope you liked it,

34
00:01:20,910 --> 00:01:22,983
‫and I will see you in the next lecture.
