OAuth 1.0 Authorization Flow using Flickr and Postman

While technically outdated, OAuth 1.0 is still around and older applications still use it.

In this tutorial, I will show you how to make the requests needed for an OAuth 1.0 authorization flow using Postman. This includes digesting the Flickr API documentation but letting Postman compute the OAuth signature (oauth_signature).

This tutorial was very helpful to finally get access to Flickr API. Also, in the new version of Postman, under Authorization, you can now add the callback URL. It won't work if you put it in params, in the newest version of Postman.

I'm working on get api from Flickr and trusly I have no idea until this vid. Thank you so much

[bspinnfade]

Thanks for showing this Valentin I was in desperation when I saw the flickr API was OAuth 1.0 as I'm much more familiar with OAuth 2.0 and Open ID Connect :)

[giancarlo]

You are a lifesaver!! I wish I could give you more than 1 like

Hi, thanks for your effort. I have a question... Is it Possible to call an API within the Pre-request script synchronously? I need to set the environment variable token from that request then use it in the main request. Is it possible to do that or I need to chain the requests?
I found pm.sendRequest but it's async

[saadaltwaim]

thank you for this tutorial
nice & easy
i have question
i want to use Flickr for swift Development what should write in Callback URL

[gafger]

Las nuevas versiones de postman cuentan con los parámetros de verifier para utilizarlos no es necesario crearlo en paremetros

Hi thanks for sharing this, it was really helpful. A question, say if I want to automate the user consent part within postman itself without manually opening a browser window - is this possible?

[cyndicorinne]

Question: how does postman generate the extra OAuth 1.0 parameters, if I were to implement my own code?

[muraliv]

Hi, Thanks for the video! I have a question, Should I need to pass the application name in the header? (like application_name: my_app)

[salmankrd]

Hi, i want to upload a picture on flickr using the api, which token shall i use in the setToken function?
I always get an error message saying you do not have permission.

[ishfaqbabar]

i also need a same for LTI APIs. it also uses oauth v1 but its has some extra steps in my opinion. this API used for Learning management system to access course contents. Many LMS provider are using LTI .like canvas, Whiteboard, pearson. ETC please make a video on it

[alexanderhatley]

You can avoid a nasty error Status: 401 Unauthorized
To do this, select Add authorization data to: Request Headers in Authorization.

[nancyfazal]

Hi, thanks for the nice video. But I am stuck at some point while requesting token. Though, I have specified all the parameters still meeting this error constantly:
Any suggestions.

[Draco]

Hey! good video help me a lot, but i stuck at Step 3— Exchanging the Request Token for an Access Token, do all like in your video, but i have respond "Status: 401 Unauthorized

[maghilvannanm]

Iam getting CORS error while using in browser, so wanna know whether you're using desktop or browser

[stokitko]

Why the Step 1 is needed? "When Your App first makes an API call for a request token.
OAuth 2 doesn't have it and we can just simply redirect a user to the AS

[ighsight]

oauth sucks. Thanks for this great explainer video, I am slightly less confused now.
