69 00:06:09,320 --> 00:06:16,820 Well, this is the interface of graphical interface that we can use to interact with a graph API explorer 70 00:06:16,820 --> 00:06:17,870 of Facebook. 71 00:06:18,590 --> 00:06:22,670 So using this interface is one way to interact with the API. 72 00:06:22,850 --> 00:06:25,130 Another way is to use Python. 73 00:06:25,880 --> 00:06:32,780 Both this interface gives us some key data that we need, and then we can switch to Python. 74 00:06:32,990 --> 00:06:34,880 So let's explore this interface first. 75 00:06:35,090 --> 00:06:35,900 What do we have here? 76 00:06:35,930 --> 00:06:37,490 Well, we have the access token. 77 00:06:37,910 --> 00:06:43,100 This one in here, you can press the button to copy it and put it in your Python script. 78 00:06:43,130 --> 00:06:44,150 I'll do that later. 79 00:06:44,600 --> 00:06:50,240 For now, it's important to know that you need to be careful with this access token where you put it, 80 00:06:50,480 --> 00:06:54,500 especially if this is your main Facebook account. 81 00:06:54,770 --> 00:06:57,200 For me, this is just a throwaway account, so. 82 00:06:58,520 --> 00:07:03,830 This just by phone, is how I described this, as I told you, so I'm not going to worry much about 83 00:07:03,830 --> 00:07:10,730 that, and I'm down here, you have the ad that we created the API app. 84 00:07:11,180 --> 00:07:13,100 So are this app in my case? 85 00:07:13,720 --> 00:07:19,310 No, this indicates if you're working with a user accounts or a page. 86 00:07:19,520 --> 00:07:25,880 So we have Facebook pages and we have user calls here we are working on Facebook user accounts. 87 00:07:26,210 --> 00:07:29,870 So this should be user token here and then we have permissions. 88 00:07:30,170 --> 00:07:36,290 So currently we only have permission to the public profile of this user. 89 00:07:36,290 --> 00:07:44,660 Accounts by phone is how, in my case, that to me is the API can only access posts and photos which 90 00:07:44,660 --> 00:07:45,770 are public. 91 00:07:46,160 --> 00:07:50,220 For example, this posting here is not public. 92 00:07:50,250 --> 00:07:51,830 This is shared only with friends. 93 00:07:51,830 --> 00:07:57,590 Therefore, with this permission, we cannot access that post. 94 00:07:58,100 --> 00:08:06,140 Therefore, what we want to do here is search for user posts and presence and also you want to give 95 00:08:06,140 --> 00:08:08,690 access to photos, so user photos as well. 96 00:08:12,430 --> 00:08:21,100 And leave them there, once you have done that, then you need to press again on generates access token 97 00:08:21,970 --> 00:08:25,600 so that you gets a new token for those permissions. 98 00:08:26,170 --> 00:08:32,740 Right now, you see that these are not green anymore, so they have been added to permissions. 99 00:08:32,960 --> 00:08:34,240 And this is a new token. 100 00:08:34,240 --> 00:08:39,280 So that's the new token you need to use now if you want to access user photos and user posts. 101 00:08:39,549 --> 00:08:44,440 That token is different from the previous form, so you can discard the previous token. 102 00:08:44,710 --> 00:08:45,460 Don't use it. 103 00:08:45,850 --> 00:08:47,930 Then we jump into this area here. 104 00:08:47,980 --> 00:08:48,700 Let me zoom in. 105 00:08:50,050 --> 00:08:54,730 We have this URL are a mixture moorfields equal I.D. common name. 106 00:08:55,090 --> 00:08:56,560 And I'm going to press submit. 107 00:08:57,310 --> 00:09:05,890 So what I did now is I performed a query to the API and we got back some data on what is this, what 108 00:09:05,900 --> 00:09:07,870 we have the I.D. and we have the name. 109 00:09:08,830 --> 00:09:12,670 The I.D. is the user I.D. of my Facebook account. 110 00:09:12,700 --> 00:09:20,450 So all Python is told and that this is a name that vets use it to contest in. 111 00:09:20,620 --> 00:09:26,200 In your case, it could be your Facebook name and surname or whatever you have in your Facebook profile 112 00:09:26,200 --> 00:09:26,500 name. 113 00:09:27,130 --> 00:09:33,160 So we just quoted some data with this query, but we did that through this interface. 114 00:09:33,160 --> 00:09:36,400 So how can we do the same via Python? 115 00:09:36,850 --> 00:09:44,200 Well, to do the same via Python, you need to go down here to get code presents and then you have different 116 00:09:44,200 --> 00:09:50,530 types here, so you have JavaScript implementation of this. 117 00:09:50,710 --> 00:09:58,990 But what we need to do is go to see your URL and then copy that entire thing. 118 00:09:59,230 --> 00:10:08,710 So right click copy or control, see and then go to Python and I'm going to import requests first. 119 00:10:08,740 --> 00:10:15,760 That's the Python third party library that allows you to make a request to the Graph API explorer. 120 00:10:15,910 --> 00:10:22,180 So in the case of the VA interface, this interface makes a request to the API. 121 00:10:22,930 --> 00:10:29,110 In this case, we want to make requests through this request library from Python and then construct 122 00:10:29,110 --> 00:10:40,480 the URL you want to request or remove that part and the leaf only of double quotes followed by HTP as 123 00:10:40,480 --> 00:10:45,820 graph, etc. And it closes with a double quotes. 124 00:10:45,820 --> 00:10:47,360 So that's a Python string. 125 00:10:47,360 --> 00:10:47,590 No. 126 00:10:48,190 --> 00:10:58,900 And then we do respond to requests that get and we answer that you went in there and then we print out 127 00:10:59,020 --> 00:11:03,850 a response, the content and run. 128 00:11:07,150 --> 00:11:14,710 Request is going to be installed on my repo because it was not installed, and we should be seeing the 129 00:11:14,710 --> 00:11:15,940 results in just a bit. 130 00:11:22,780 --> 00:11:27,730 Yes, so that's the results is the same data that we got in here. 131 00:11:29,200 --> 00:11:33,900 Now just one thing you see this Barbie here, which means this is a big string. 132 00:11:34,720 --> 00:11:41,250 So if you want to get a plane stream, you want to say Texea instead of content, we're on again and 133 00:11:41,260 --> 00:11:44,710 then you should get a plane string, not be in front. 134 00:11:46,270 --> 00:11:54,370 So what's going on is well, and here you have this access token and this access token is fetched automatically 135 00:11:54,370 --> 00:12:02,080 by this interface in Python, though when you copy that's €c codes. 136 00:12:02,500 --> 00:12:05,740 What we copy is we also copy the access token. 137 00:12:05,980 --> 00:12:11,230 So you see this part of your access token is equal to the actual access token, which you find also 138 00:12:11,230 --> 00:12:11,710 in here. 139 00:12:12,220 --> 00:12:17,710 So that means access token now is included in here. 140 00:12:17,950 --> 00:12:19,150 That's my access token. 141 00:12:19,570 --> 00:12:24,630 And then we have this other ports onto here. 142 00:12:26,500 --> 00:12:30,790 So that's the base URL of the Graph API graph. 143 00:12:30,790 --> 00:12:34,930 That's Facebook dot com v thirteen point zero. 144 00:12:35,050 --> 00:12:38,320 And then we have this Port Me question mark. 145 00:12:38,890 --> 00:12:47,920 Fields is equal to D, and we have this percentage too, which means a empty space, a white space. 146 00:12:48,130 --> 00:12:50,050 And then we have a name. 147 00:12:50,830 --> 00:12:59,590 So that is the same as we see in here, more or less the same, although the commas are white spaces 148 00:12:59,590 --> 00:13:00,230 in here. 149 00:13:01,300 --> 00:13:03,070 So let me explain what this means. 150 00:13:03,400 --> 00:13:08,840 Well, MI is the equivalent of placing this idea. 151 00:13:08,980 --> 00:13:14,440 So this is your unique I.D. of of your Facebook user account. 152 00:13:14,950 --> 00:13:24,070 So even if I place that idea instead of me in here and I run, I will get the same results. 153 00:13:24,880 --> 00:13:32,140 So that's the standards, you know, and you can do the same in here, so you can place that idea instead 154 00:13:32,140 --> 00:13:32,620 of me. 155 00:13:33,310 --> 00:13:37,930 And then followed by question mark submits and you get the same results. 156 00:13:39,430 --> 00:13:45,730 So often have a question mark when we have the query, what fields do we need from this user account? 157 00:13:46,180 --> 00:13:48,520 Well, we need the I.D. and we need the name. 158 00:13:52,160 --> 00:14:00,230 And if we add posts, as I just did, it gives us also the information about posts. 159 00:14:01,870 --> 00:14:05,380 So let's see what we've got here. 160 00:14:06,670 --> 00:14:09,640 So we have Heidi, as the key of this dictionary. 161 00:14:09,760 --> 00:14:11,830 We have name as another key. 162 00:14:12,220 --> 00:14:14,230 So each key has its own value. 163 00:14:14,500 --> 00:14:24,520 Python Nesto is the value of name, and then we have the post's key supports has as a value of this 164 00:14:24,520 --> 00:14:25,340 dictionary. 165 00:14:26,440 --> 00:14:32,560 And so this is a dictionary which has another key Delta and Delta has as a value of this list of this 166 00:14:32,560 --> 00:14:33,100 list. 167 00:14:33,430 --> 00:14:34,060 The dictionaries. 168 00:14:34,270 --> 00:14:35,800 So this is one dictionary. 169 00:14:35,800 --> 00:14:38,020 It starts here, it ends in here. 170 00:14:38,470 --> 00:14:45,850 And this dictionary contains one posts, so it represents one Facebook post on my user account. 171 00:14:45,890 --> 00:14:47,200 Here I have two posts. 172 00:14:47,920 --> 00:14:52,420 This is this is my first post on Facebook and it says this comment. 173 00:14:52,940 --> 00:14:54,760 And that's another post. 174 00:14:55,030 --> 00:14:59,020 So two posts and here as well, we get these two posts. 175 00:14:59,110 --> 00:15:03,010 One here, you see, this is my second post. 176 00:15:04,180 --> 00:15:07,610 And then we have this other one in here. 177 00:15:07,660 --> 00:15:09,310 This is my first post. 178 00:15:10,510 --> 00:15:13,540 And then each post has a 90. 179 00:15:14,380 --> 00:15:15,670 Let me expand this a bit. 180 00:15:16,990 --> 00:15:18,670 So that's the idea of the post. 181 00:15:20,830 --> 00:15:24,040 Now you ask, what's all these other things? 182 00:15:25,090 --> 00:15:31,090 So we have two posts, then we have this other dictionary here. 183 00:15:31,120 --> 00:15:37,390 So one, two, three and four. 184 00:15:38,320 --> 00:15:40,880 What these are is photos. 185 00:15:40,900 --> 00:15:44,770 So I have four photos here on my Facebook profile. 186 00:15:45,820 --> 00:15:49,900 It's one to this is a Facebook main picture. 187 00:15:50,080 --> 00:15:53,410 So it's one two three four, actually without the tiger. 188 00:15:58,720 --> 00:16:04,540 And that's what we have in here now, let's repeat the same query in Python. 189 00:16:04,660 --> 00:16:05,470 So again, get. 190 00:16:05,830 --> 00:16:10,660 Go to €c and copy that entirely. 191 00:16:10,670 --> 00:16:14,860 Go to Python in the URL paste. 192 00:16:14,860 --> 00:16:15,990 That's clean it out. 193 00:16:18,770 --> 00:16:24,220 We run and we should get the same dictionary in here. 194 00:16:27,150 --> 00:16:31,470 So that's the dictionary is the same one with this in here. 195 00:16:32,280 --> 00:16:36,510 Next, how can we get one single posts? 196 00:16:37,170 --> 00:16:38,280 We have multiple polls. 197 00:16:38,610 --> 00:16:39,960 How can we get just one? 198 00:16:40,470 --> 00:16:42,420 Or how can we get to one single photo? 199 00:16:42,790 --> 00:16:43,560 Let me show you that. 200 00:16:44,430 --> 00:16:51,030 Now what you do is you need the I.D. of the posts that you want. 201 00:16:51,360 --> 00:16:57,360 So for example, this second post here we give the I.D. with place. 202 00:16:57,360 --> 00:16:59,430 It's in the beginning in here. 203 00:17:00,540 --> 00:17:02,820 So that is followed by a question mark. 204 00:17:03,450 --> 00:17:08,880 And then what fields do we need if we run this query as it is? 205 00:17:09,300 --> 00:17:14,010 We're going to get this error tried accessing not existing fields posts. 206 00:17:15,150 --> 00:17:24,300 Of course, it's not a field of one post, so ID name and posts were fields of the user accounts. 207 00:17:24,990 --> 00:17:29,310 So it gives us the idea of the user calling the name of the user account and the posts. 208 00:17:29,550 --> 00:17:35,550 So these are attributes of the user account, but these are not attributes or a pause. 209 00:17:35,580 --> 00:17:39,120 So for posts, you could have comments. 210 00:17:40,270 --> 00:17:42,420 Now this post the second post. 211 00:17:44,950 --> 00:17:48,310 Doesn't have any comments, so I'm going to add a comma now. 212 00:17:49,110 --> 00:17:59,170 Hey, this is a comment and then around this query again submits and then we have this common ski. 213 00:17:59,690 --> 00:18:03,310 And so this is the text of a comment. 214 00:18:04,600 --> 00:18:06,820 And the idea of a comment as well. 215 00:18:07,630 --> 00:18:09,580 So everything has an idea. 216 00:18:10,720 --> 00:18:16,660 And of course, you can do the same with this gets cold and put this in python to access it with requests. 217 00:18:17,830 --> 00:18:18,700 Photos No. 218 00:18:19,150 --> 00:18:21,580 Well, let's get to again me. 219 00:18:22,300 --> 00:18:30,340 So with me, you get the user I.D. And so if you add the slash and write posts and press, enter again, 220 00:18:30,430 --> 00:18:34,420 this is going to give you the posts and also the photos. 221 00:18:34,840 --> 00:18:38,500 So again, try to get the idea of one post in here. 222 00:18:39,250 --> 00:18:44,610 And of course, in Python, you can also iterate over these dictionaries and gets all the posts and 223 00:18:44,620 --> 00:18:49,870 then make another loop where you access each posts. 224 00:18:49,870 --> 00:18:54,070 You grab that idea and access it and then get the pictures. 225 00:18:54,580 --> 00:18:59,710 If you only want the photos, though, you can remove posts and write photos. 226 00:19:03,710 --> 00:19:09,770 But you also need to add slash uploaded to actually get the list of photos. 227 00:19:10,580 --> 00:19:15,320 So now we have the photos and we also have a description of the photos, if there is any. 228 00:19:15,890 --> 00:19:22,160 So when you upload the photo as a user on your Facebook account, it gives you the option to enter a 229 00:19:22,160 --> 00:19:22,830 description. 230 00:19:22,850 --> 00:19:24,890 So that's the description of the photo. 231 00:19:25,160 --> 00:19:26,480 And as the idea of the photo. 232 00:19:26,720 --> 00:19:30,140 So let's get this photo of this particular photo. 233 00:19:31,100 --> 00:19:40,760 You want a copy of that I.D. pasted directly in here and then add the question mark fields if you want 234 00:19:40,760 --> 00:19:41,640 to give any fields. 235 00:19:41,660 --> 00:19:43,190 Otherwise, just leave it like that. 236 00:19:43,820 --> 00:19:47,090 Submit that to give you vets. 237 00:19:47,390 --> 00:19:54,470 If you want to get the link of the photo again, you want to add the question mark fields a single to 238 00:19:54,980 --> 00:19:55,790 link. 239 00:19:56,900 --> 00:20:03,890 Press submits, and that should give you this link, if you could, that's going to take you to this 240 00:20:03,890 --> 00:20:04,610 page. 241 00:20:04,940 --> 00:20:06,890 You want to follow the coupe case. 242 00:20:15,990 --> 00:20:16,570 Try again yet. 243 00:20:16,860 --> 00:20:19,980 So that's the link of the photo. 244 00:20:20,670 --> 00:20:27,240 No, as you can see, this URL points to the photo page, not to the image file itself. 245 00:20:27,840 --> 00:20:32,190 So if you want the actual image, you want to do something else. 246 00:20:32,550 --> 00:20:38,900 So let's go back in here and sometimes you get this error of error validating access token. 247 00:20:38,910 --> 00:20:40,440 The session is invalid. 248 00:20:41,520 --> 00:20:45,900 That's happens because these tokens are only used for six minutes. 249 00:20:45,900 --> 00:20:48,210 They are valid for that six minutes. 250 00:20:48,210 --> 00:20:52,380 Then you want to press that button again to generate another access token. 251 00:20:54,540 --> 00:20:58,530 And then we want to run that square again, which was this. 252 00:21:01,060 --> 00:21:05,170 So in this new page with this new access token, submit. 253 00:21:06,940 --> 00:21:10,420 Oh, I forgot to enter the first number it's on. 254 00:21:11,050 --> 00:21:12,280 I missed one digit. 255 00:21:12,700 --> 00:21:17,960 So again, so that's the Facebook page of the image. 256 00:21:17,980 --> 00:21:21,250 Now if you had another here, common images. 257 00:21:22,210 --> 00:21:29,250 So you'll see that this interface can also suggest you fields images and presence of myths. 258 00:21:31,300 --> 00:21:33,880 Then you get this. 259 00:21:34,540 --> 00:21:36,820 So you have this link. 260 00:21:37,360 --> 00:21:41,920 Press it's a that's that points you to the actual image file. 261 00:21:46,470 --> 00:21:48,060 So there are two links, actually. 262 00:21:48,090 --> 00:21:51,900 One, you have this big image and want a smaller image. 263 00:21:55,470 --> 00:21:59,970 So with five and then you can choose to download whichever you want. 264 00:22:00,540 --> 00:22:09,000 So next, let's try to download this first image and see if it's an actual image file in Python. 265 00:22:11,070 --> 00:22:13,050 So first of all, we need to get the codes. 266 00:22:15,040 --> 00:22:15,580 Cockpit. 267 00:22:18,110 --> 00:22:22,160 Place, it's in the other variable clean that's. 268 00:22:24,590 --> 00:22:25,490 So that's zero. 269 00:22:26,390 --> 00:22:29,930 This should give us that same dictionary. 270 00:22:30,590 --> 00:22:34,280 So now we want to access a let's go again in here. 271 00:22:34,560 --> 00:22:37,160 Not this one, this one. 272 00:22:37,460 --> 00:22:46,760 So I want to look at here because we have a cleaner view of this dictionary, so we want to access the 273 00:22:46,760 --> 00:22:48,050 images key. 274 00:22:49,340 --> 00:22:50,090 Let's do that. 275 00:22:52,040 --> 00:23:03,260 So data is equal to Respawn's the text and if we print just data images. 276 00:23:07,790 --> 00:23:15,710 We get this error because Delta is actually a strength at this point. 277 00:23:17,490 --> 00:23:22,620 So it's a strength, even though it looks like a dictionary, that dictionary is wrapped inside a string. 278 00:23:22,830 --> 00:23:29,540 So we want to convert that string into an actual Python Dictionary object for that. 279 00:23:29,540 --> 00:23:35,880 So we need to import Jason than that. 280 00:23:35,970 --> 00:23:39,780 So it would be equal to JSON that loads. 281 00:23:40,590 --> 00:23:42,090 And then we enter Delta. 282 00:23:43,290 --> 00:23:49,800 So Delta currently is a string so that Delta is a string, but it will be converted into a dictionary. 283 00:23:50,160 --> 00:23:51,510 So if I print it all now. 284 00:23:52,230 --> 00:23:57,780 Now we have a DICT, so let's bring out the delta. 285 00:23:57,790 --> 00:24:05,790 It looks the same as you will see is still the same, but now we can access the keys of the dictionary 286 00:24:06,330 --> 00:24:09,900 because Python now knows how to pass that object. 287 00:24:11,250 --> 00:24:17,070 So that's who gave us this list, which is basically, yeah, this one here. 288 00:24:18,180 --> 00:24:18,900 That's a list. 289 00:24:19,270 --> 00:24:22,950 Now let's get the first item of that list, which is this first dictionary. 290 00:24:23,040 --> 00:24:27,870 So the list has to dictionaries this one, and that's another one. 291 00:24:28,830 --> 00:24:33,270 So by applying an index of zero. 292 00:24:35,900 --> 00:24:38,430 We get that first dictionary rights. 293 00:24:39,230 --> 00:24:43,580 And then out of the dictionary, so we get this one. 294 00:24:43,730 --> 00:24:50,540 And then out of that, we get the source key, the value of the source key. 295 00:24:52,780 --> 00:24:53,530 Soldiers. 296 00:24:57,060 --> 00:25:01,710 So that gives us the URL, which if you click it, it takes you to that image. 297 00:25:02,010 --> 00:25:03,830 No, next. 298 00:25:04,200 --> 00:25:07,830 Let's save this URL to an image. 299 00:25:07,860 --> 00:25:08,850 You are a variable. 300 00:25:10,170 --> 00:25:13,680 Remove the parentheses of the print function. 301 00:25:15,300 --> 00:25:22,590 And then what we want to get now is to get the contents of that image, the Boyds. 302 00:25:23,190 --> 00:25:24,870 And we do that. 303 00:25:27,500 --> 00:25:37,610 With requests to gets again, and this request gets now, gets zero of the image images were so previously 304 00:25:37,610 --> 00:25:45,920 it got it got the usual or that a web page and now it's a you or a loved one image and we extract the 305 00:25:45,920 --> 00:25:46,670 content. 306 00:25:48,230 --> 00:25:50,990 So now we want the content, not texts. 307 00:25:51,000 --> 00:25:52,760 So we were working with bytes. 308 00:25:53,270 --> 00:25:57,530 Images are binary, files are not, they are not text files. 309 00:25:58,490 --> 00:26:10,030 And then we open a file locally with open image the chief p g in right binary mode as file and in that's 310 00:26:10,040 --> 00:26:11,090 new file object. 311 00:26:11,090 --> 00:26:11,720 We were right. 312 00:26:12,110 --> 00:26:22,100 Image voids that variable and we run the script adds an image. 313 00:26:22,100 --> 00:26:25,130 The JPG chief file is downloaded. 314 00:26:25,310 --> 00:26:28,070 We click it and we see the actual cat image. 315 00:26:29,660 --> 00:26:35,810 So that's how we can get an actual photo from Facebook via Python. 316 00:26:36,530 --> 00:26:47,060 And lastly, if you want to see the documentation, you want to go to docs and just over the mouse there 317 00:26:47,060 --> 00:26:49,460 and then go down to Graph API a reference. 318 00:26:52,950 --> 00:26:56,500 And even here in this listing here. 319 00:27:00,450 --> 00:27:03,960 You'll see all the notes that you can get. 320 00:27:04,380 --> 00:27:07,920 So, for example, we worked with photos. 321 00:27:08,000 --> 00:27:09,540 So I'm going to search for photos. 322 00:27:11,880 --> 00:27:12,960 It's a long document. 323 00:27:14,710 --> 00:27:16,420 So photo is something that we got. 324 00:27:16,470 --> 00:27:22,050 If you click that, it'll take you in here. 325 00:27:22,320 --> 00:27:29,880 So if you scroll down, for example, you see a table of fields that you can pass to photos. 326 00:27:32,470 --> 00:27:41,590 So in this example, here we pass the link field for photos, but you can pass all the fields as you 327 00:27:41,590 --> 00:27:43,540 see in this table. 328 00:27:47,240 --> 00:27:50,640 So with that, I wanted to finish this video. 329 00:27:50,660 --> 00:27:55,760 There's more and more about the Facebook API, and of course, I cannot cover it. 330 00:27:55,760 --> 00:28:03,280 All of the points of visibility was to give you some orientation on how to start to get started with 331 00:28:03,290 --> 00:28:04,700 a Facebook API. 332 00:28:05,540 --> 00:28:12,830 The things you can do with the Facebook API are infinite, so I hope this helps you to get some ideas. 333 00:28:12,830 --> 00:28:17,120 And whenever you need the Facebook API, just click this video to get started. 334 00:28:17,540 --> 00:28:18,000 Thank you. 335 00:28:18,180 --> 00:28:18,350 You.
