Generating User Api Keys with REST API

Umer_Mirza · 5월 1, 2017, 10:55오후

Hi
I am trying to generate User api keys. I know I can do it from admin dashboard. But instead of there I want to generate by making REST calls. I am following this post User API keys specification
I am getting error “THIS PAGE IS PRIVATE OR DOES NOT EXISTS” when I try to make a GET request to this https://unityforum.discoursehosting.net/api_key/generate?redirect_url=www.google.com.pk&client_id=2&access_level=read

Can someone please show me how my url should look like with the paramters. I am also confused what exactly is client_id here? Is it the id of the user whose api needs to created or is the username? Also can I use any url as redirect_url? For the record I have added this redirect url in my admin settings.

I am also looking for same solution, can anyone help in this?

Hello,

to generate an api key for a user:

curl -X "POST" "http://localhost:4000/admin/users/1/generate_api_key?api_key=10efbf2c9a84dfb3b6f60ffa117c029bda7fc9fb8f861ccd0dc8e8fbfa86968d&api_username=joffreyjaffeux"

Learn more about it:

@j.jaffeux That’s not the same “API” that @Umer_Mirza was asking about. I put “API” in quote because it may not exist?

The User API keys specification RFC talks about the use case of allowing users themselves the ability to request and API key so that a third party developed app may perform actions on their behalf. You would never want to give a third party your site API key because they would have full access.

I would ask this question in User API keys specification but that topic is closed. Does the API that @sam proposed in that post actually exist or not?

sam · 11월 9, 2017, 6:31오전

Yes user api keys exists and are consumed by the mobile app, look at the source code of the mobile app for exact specifications for now.

I would love to have this better documented so if you want to take that project on

djensen47 · 11월 9, 2017, 6:34오전

Awesome, thanks for the quick response.

Well, maybe I can get something started for documentation. I have to do something on this front anyway so I can post what I come up with here.

This is the endpoint sam is talking about I think:

Thanks @j.jaffeux. I was drafting a similar message but I only had the code from the mobile app. These other code snippets are very useful.

When I tried this API against my own server using Postman, I kept getting a 400 error with no details. My Ruby is a little rusty but I’ll dig into the code more but if you happen to know why a 400 might happen that would be helpful.

djensen47 · 11월 9, 2017, 11:12오후

I just tried adding my site to the official Discourse app, and it worked so I must be doing something wrong with regard to using the API in Postman.

Aside: I thought the app only worked for officially hosted Discourse sites.

sajattack · 12월 28, 2017, 10:18오후

I’m getting error code 400 when I visit https://community.frontrowcrew.com/user-api-key/new

sajattack · 1월 12, 2018, 8:17오후

Can I get some assistance on this @sam?

codinghorror · 1월 13, 2018, 2:58오전

Did you want to purchase a hosting contract with us?

sajattack · 1월 13, 2018, 3:09오전

No, but if you can point me in the right direction I’d be happy to document it for others.

sajattack · 4월 2, 2018, 1:01오전

By looking at the URL generated by the discourse android app, I’ve uncovered the fields required for
/user-api-key/new

scopes - these are the permissions of the api key, in the case of the official app, to read notifications and to read session info
client-id - hex string, dunno
nonce - another hex string, used as a cryptographic nonce
auth_redirect - url to redirect to after permission is given
application_name - the name to display to the user of the application using the api
public_key - a public RSA key

Still a few questions:

What are all the valid values for scopes?
Where does the client-id come from?
Are all api responses encrypted with the public key or what is it’s purpose?

sajattack · 4월 2, 2018, 4:21오전

So, looking at the source code, client-id is 32 random bytes and nonce is 16 random bytes.
Edit: It’s actually 32 & 16 nybbles, but the code generating it is called randomBytes(32)

sajattack · 4월 2, 2018, 10:37오후

Found the scopes!

I’ve written a program that generates URLs of this specification, enough to get me to this screen:

But when I press Authorize I get a 403.

sam · 4월 2, 2018, 11:26오후

After authorize you will be redirected, so the redirect URL needs to go somewhere where you can handle decrypting the payload it redirects with.

Also there is a site setting that lists where the redirect is allowed to go.

sajattack · 4월 3, 2018, 7:29오전

Ok, got my api key. Is this a different API than the admin one documented at http://docs.discourse.org ?

sajattack · 4월 8, 2018, 11:41오후

When I try to make a post with the api documented at http://docs.discourse.org using a user api key, it says

You are not permitted to view the requested resource. The API username or key is invalid.

So I think it’s a different API or needs different fields (client_id?) for authentication.
