1.319 -> Hello and welcome to this session on Postman beginner tutorial And today we are going to

6.34 -> see how can we do debugging in Postman and we will go very basic step-by-step and we

12.829 -> will learn how do we debug with Postman console?

15.759 -> How do we open the postman console window?

18.24 -> And then we will discuss about all the information that we can see on the postman console window

23.74 -> How do we clear the logs and then some statements of logging and we will also see the app debug

29.96 -> logs so let's get started and let me switch to my Postman and here before I begin Let

36.36 -> me tell you I am using a dark theme so you can go to your settings And if you go to settings

42.85 -> we have the themes here so you can select the lighter theme or the Dark theme So I'm

46.31 -> using the Dark theme of Postman here and here let So I'm using the Dark theme of Postman

50.51 -> here and here let me go to any of the requests so This is a get user request that we have

56.5 -> created in our last session now while working with Postman they will be a need that you

62.179 -> want to debug your request or your scripts or you want to see what exactly is happening

66.99 -> so that you can troubleshoot and find the issues So for that one of the very useful

72.77 -> tool in Postman is the postman console and you can go to your view And here you can see

81.811 -> how show Postman console you can also use the keyboard shortcut, alt + Ctrl + C In case

88.83 -> you are on Mac You can press alt + command + C combination And also if you go to the

94.25 -> bottom of the postman you have this icon here and again, you can click this to open the

101.46 -> postman console So I will click here and it will open the postman console window and let

107.33 -> me split my screen so that you can See the postman console and the postman Windows side-by-side

113.75 -> And yes this is my Postman console window on the right and on the left I have my Postman

119.67 -> now, whatever I will run will be logged in the postman console So let me go to the get

129.57 -> user request and let me just hit send And yes you can see everything is now logged onto

140.56 -> Postman console and here you will find that all the scripts output are logged on the postman

147.33 -> console And then the actual request and response is also logged and then in case you have any

152.67 -> variables they are also being referred and the actual value is shown now here these are

159.02 -> some of the scripts that I had written earlier so you can see that and then if you go here,

165.47 -> this is the actual And you can expand this and you have the request header the response

172.42 -> header and then if you go down you have here the response body So if I expand this one

180.87 -> you can see the data as well from the response Now, you can also see the raw format and the

188.62 -> pretty format If you go to the raw format, this is the actual request that was sent to

194.08 -> the server and this is the actual request which was received back from the server before

200.77 -> Postman could apply its formatting So if you want to see the actual response that was received

205.99 -> before Postman applied some of it it's formatting and beautification This is what you can see

210.99 -> on the console window Also, you can see here in case you have any variables in your request

218.06 -> So for example, if I see my request there was a variable URL and this is the actual

224.58 -> value if you if I hover you can see the actual You and in the postman console window, it

230.16 -> actually refers the variable and shows the actual value So sometimes you will also need

235.31 -> to check whether your variable is being referred properly or the value is being referred properly

239.84 -> from the variable This is again, you can find in the postman console window So here you

245.04 -> can find all the script output all the error logs and everything One thing to note here

249.29 -> is in the postman console window The locks are preserved for the session of the postman

254.41 -> console window is open for example, if If I close this Postman console and try to start

260.16 -> it again, you will find no earlier logs So the locks are preserved only for the session

266.34 -> when the window is open So I will have to run it again to see the logs and you can also

272.49 -> clear the logs from this button We have a clear button here So you can clear the logs

278.21 -> Now The other useful thing is you can also use

309.36 -> these

346.94 -> The next important thing is you can also see the app debug locks so you can go to your

354.71 -> Postman and go to view and here you have developer option and here you can see show devtools

362.6 -> If you click here you will have a new window where you can see the elements console sources

370.13 -> on the console You can see all the app locks and this will be very useful while troubleshooting

375.63 -> you can also see the sources so you can see all the files and folders being referred to

379.83 -> in my case You can see the folder being referred is the postman folder And then you can also

385.87 -> expand and see everything but is being used So this is some deep level of troubleshooting

390.84 -> and Analysis If you really want to do this you can go to this console window and then

395.9 -> check for all these logs and parameters and do your troubleshooting

399.92 -> So this is how you can do a very quick debugging in Postman.
