<v ->Hi guys and welcome back.</v>

2
00:00:02.320 --> 00:00:03.640
In this section, we're gonna be looking

3
00:00:03.640 --> 00:00:06.380
at interacting with APIs.

4
00:00:06.380 --> 00:00:08.280
APIs are a really simple thing.

5
00:00:08.280 --> 00:00:09.585
They're basically a programme

6
00:00:09.585 --> 00:00:12.190
that receives data from you

7
00:00:12.190 --> 00:00:15.570
and gives you data back be that what it may.

8
00:00:15.570 --> 00:00:17.630
So, in this section, we're going to be using this API

9
00:00:17.630 --> 00:00:20.370
called open exchange rates.

10
00:00:20.370 --> 00:00:22.160
This receives some data from you,

11
00:00:22.160 --> 00:00:24.740
which is what you want from it

12
00:00:24.740 --> 00:00:26.500
and it sends you some data back.

13
00:00:26.500 --> 00:00:30.597
For example, the current latest currency exchange rates.

14
00:00:30.597 --> 00:00:34.140
So, let's have a look at open exchange rates.

15
00:00:34.140 --> 00:00:36.640
First thing to do is of course to sign up

16
00:00:36.640 --> 00:00:38.060
and they've got some paid plans

17
00:00:38.060 --> 00:00:40.240
but they've also got a free plan.

18
00:00:40.240 --> 00:00:41.860
The free plan is a bit limited

19
00:00:41.860 --> 00:00:43.200
but it's okay for what we wanna do

20
00:00:43.200 --> 00:00:45.600
and to learn about APIs.

21
00:00:45.600 --> 00:00:47.370
So, sign up to the free plan

22
00:00:47.370 --> 00:00:51.730
and then let's go over to our dashboard.

23
00:00:51.730 --> 00:00:52.960
When you're in your dashboard,

24
00:00:52.960 --> 00:00:54.510
you'll see something like this.

25
00:00:54.510 --> 00:00:57.380
I've got already some API requests that I've made.

26
00:00:57.380 --> 00:00:59.140
I've interacted with the API already,

27
00:00:59.140 --> 00:01:01.900
so here it shows me what I have interacted with

28
00:01:01.900 --> 00:01:05.240
and when but since we're only just getting started,

29
00:01:05.240 --> 00:01:08.789
do go to your App IDs section of the page

30
00:01:08.789 --> 00:01:12.760
and then create a new app ID.

31
00:01:12.760 --> 00:01:16.700
The API needs this app ID whenever you ask it something

32
00:01:16.700 --> 00:01:17.720
so it knows it's you

33
00:01:17.720 --> 00:01:19.390
and that you have an account,

34
00:01:19.390 --> 00:01:21.740
so by sending them this string here,

35
00:01:21.740 --> 00:01:24.140
the app ID, then they'll know

36
00:01:24.140 --> 00:01:26.359
that you are a valid user.

37
00:01:26.359 --> 00:01:30.800
Just copy that and let's go over to our programme

38
00:01:30.800 --> 00:01:31.960
where we're gonna start working

39
00:01:31.960 --> 00:01:33.390
on interacting with this API,

40
00:01:33.390 --> 00:01:35.390
so once you've got this, that's everything you need.

41
00:01:35.390 --> 00:01:36.940
I'll see you in the next video.
