I have a Firebase function that is triggered onRequest(), using the firebase-admin SDK and using Express as middleware. This function is not expected to be tied to a Firebase client/frontend (meaning, it is expected that this function can be called via curl -X POST ... etc.).
I want to secure this function such that only users with access to the Firebase project can make requests. I've found Firebase ID Tokens, and see how to create them on the client side.
My issue is that I don't have a client to create them from.
Is there a way to create an ID Token for an authorized user using the CLI, or another similar method?
E.g., something like
firebase login
firebase use <project-id>
firebase generate-id-token // would return an ID token with standard expiration rules.
There isn't a command in Firebase CLI to login as a user and print ID token. You can call Firebase Auth REST API using cURL and get the token.
curl --request POST \
--url 'https://identitytoolkit.googleapis.com/v1/accounts:signInWithPassword?key=[FIREBASE_API_KEY]' \
--header 'Content-Type: application/json' \
--data '{
"email": "user#domain.tld",
"password": "12345678",
"returnSecureToken": true
}'
I want to secure this function such that only users with access to the Firebase project can make requests.
Anyone can use the REST API but they must know the account's password to login.

I understand that I need to call:
curl --request POST \
--url 'https://auth.atlassian.com/oauth/token' \
--header 'Content-Type: application/json' \
--data '{"grant_type": "authorization_code","client_id": "YOUR_CLIENT_ID","client_secret": "YOUR_CLIENT_SECRET","code": "YOUR_AUTHORIZATION_CODE","redirect_uri": "https://YOUR_APP_CALLBACK_URL"}'
to get access token. There is some attempt to explain what are client_id, client_secret, code, redirect_uri, but it's totally cryptic to me. Can someone explain to me, what these are and where to get them?
I can login to company jira. I can create my personal access token in my profile. I cant get any meaningful support from my company. I need to get somehow from here to access token, so that I can call rest api.
OAuth needs that the user login through a web interface.
Once logged, is possible to retrieve the code you are looking for in the URL.
In my case, in order to get that code I have to open the oauth login web page of the service I want to use (in your case atlassian) and just login.
I usually manage this process with code, not using curls.
redirect_uri is where you want to be redirected after you login in the web interface.
i.e. Do I need to login with atlassian in order to call api and use data from my app ?
mobile app/Desktop App (redirect_uri will be a schema defined by you in the app, could be something like: myCompany://myApplicationExample or with desktop http://localhost should work ). In this case I suggest you to read something about deeplink for applications.
website (redirect_uri will the url of your website : https://yourwebsite.com
In my case, with the services I usually work with, cliend_id and client_secret are given per user or per application, when requested to the company which provides services you need.
I hope this can help you clarify
BY THE WAY:
if you say you already have an Access Token , you should be able to do everything without Loggin in, because the final purpose of login and use all this parameters you asked for, is to get an Access Token.
The endpoint you are trying to call, will just return you an Access Token.
The Access token is what you need in order to call rest api in this case.
I would suggest you to try to call an atlassian rest API you want, using the Access Token you already have in the headers of the rest API, and see the results.
In my case, I have to create an header like this:
Authorization : Bearer {your Access token}
I hope this helps you.
EDIT:
As shown in point 1 in this doc https://developer.atlassian.com/cloud/jira/platform/oauth-2-3lo-apps/
you should open this url by your application:
https://auth.atlassian.com/authorize?
audience=api.atlassian.com&
client_id=YOUR_CLIENT_ID&
scope=REQUESTED_SCOPE_ONE%20REQUESTED_SCOPE_TWO&
redirect_uri=https://YOUR_APP_CALLBACK_URL&
state=YOUR_USER_BOUND_VALUE&
response_type=code&
prompt=consent
read the doc on you should set redirect_uri (http://localhost is valid if is a desktop application, but you will have to implement an http listener in order to get the authorization code, I suggest you to set a schema in you app or simply use a web page url).
You should get a client_id by atlassian to use in the url,same for scope.
I don't know exaclty the state parameter but in the docs should be writtend.
Once logged you will be redirected to the redirect_uri you set, getting also this authorization_code, then you can call the /token endpoint in order to get the Access Token.
curl --request POST \
--url 'https://auth.atlassian.com/oauth/token'
--header 'Content-Type: application/json'
--data '{"grant_type": "authorization_code","client_id": "YOUR_CLIENT_ID","client_secret": "YOUR_CLIENT_SECRET","code": "YOUR_AUTHORIZATION_CODE","redirect_uri": "https://YOUR_APP_CALLBACK_URL"}'
Here you have to use the authorization code you get from the login, re use the same client_id, set also the client_secret (should be given with the client_id) and re use the same redirect_uri you used in the login url.
Once done you will have finally the Access Token, which must be used in order to call Apis.
as shown in the doc you should be able to call apis like this curl
curl --request GET \
--url https://api.atlassian.com/oauth/token/accessible-resources
--header 'Authorization: Bearer ACCESS_TOKEN'
--header 'Accept: application/json'
Where 'ACCESS_TOKEN' will be your access token obtained before.
Remind that an Access Token usually has an expiration date, after which you will need to login again or refreshing the token.
EDIT 2:
A Client ID is an identifier associated with an application that assists with client / server OAuth 2.0 authentication.
So basically is a constant string, this should be given to you from atlassian/jira in some way.
Client Secret should be given to you with Client ID from atlassian/jira.
Client_id and client_secret usually are also called api keys.
Usually the Scope is the name of the application you are requesting api keys for (you should request new api keys for each application),this is up to you, and should be comunicated to the company in your case (atlassian/jira) when requesting api keys.
(i.e. For my company I work with Trimble Connect, which is just a platform, everytime I develop for example a plugin/addon on top of it I ask them new api keys)
for what concerns the state:
state: (required for security) Set this to a value that is associated with the user you are directing to the authorization URL, for example, a hash of the user's session ID. Make sure that this is a value that cannot be guessed. You may be able to generate and validate this value automatically, if you are using an OAuth 2.0 client library or an authentication library with OAuth 2.0 support.
In the beginning I would try to give the state a random value.
I think you should ask to Atlassian how to get your api keys (maybe there's a page for that, like for Trimble Connect in my case).
I would send them an e-mail.
Seems you are not interested in call Apis from an application you are developing, but just from curls.
if I'm right, I know I have already told you, but if I were you I would definitely try to call an atlassian API not trying to get the access token from the OAuth Login, but using that ACCESS TOKEN you told me you told me you manually created.
Please try this curl:
curl --request GET \
--url https://api.atlassian.com/oauth/token/accessible-resources
--header 'Authorization: Bearer {ACCESS_TOKEN}'
--header 'Accept: application/json'
just use your Access Token string instead of {ACCESS_TOKEN} and see the results.
Due to the new updates of the Soundcloud API, I'm trying to update the authentication flow in my code ( the project was using login and password ).
But I'm blocked by a problem, and I'm losing my head.
I follow instructions on this page : https://developers.soundcloud.com/blog/security-updates-api
I manage to get a refresh token and an access token with this :
curl --request POST \
--url https://api.soundcloud.com/oauth2/token \
--header 'Content-Type: application/x-www-form-urlencoded' \
--data client_id=CLIENT_ID \
--data client_secret=CLIENT_SECRET \
--data grant_type=client_credentials
But I'm not able to execute this request, which is an example in the mentionned page, with the access token I got with the previous request :
curl --request GET \
--url 'https://api.soundcloud.com/me/tracks?limit=1' \
--header 'Authorization: OAuth ACCESS_TOKEN'
The request response is always :{"code":401,"message":"","link":"https://developers.soundcloud.com/docs/api/explorer/open-api","status":"401 - Unauthorized","errors":[],"error":null}
I tried with a refresh of my access token, and with the url "https://api.soundcloud.com/me" instead of "https://api.soundcloud.com/me/tracks?limit=1".
And always returning the same error.
Can someone help me ?
Thanks by advance, and thanks for reading.
OK, I think I got it, thanks to this question on github :
https://github.com/soundcloud/api/issues/76
"The client_credentials auth flow is meant only for server-side integration and allows access to public endpoints only. Meaning that for endpoint /me or any other user-related endpoint you have to use the Authorization Code flow which provides the client-side integration."
And here : https://developers.soundcloud.com/docs/api/guide#authentication :
"if your app needs to access only public resources, you can use the OAuth Client Credentials Flow"
I'm done with the error messages too blurry... and with me reading too fast !
I will add the correct authentication method in comments later.
UPDATE : "manual" authentication flow
As the project is behind a VPN, I can't use normal authentication flow ( redirect_uri can't be called by soundcloud !)
So :
Get a "code"
First, authenticate on SoundCloud with the account you want to access ( or ask your customer to do it )
In your browser, type this url :
https://api.soundcloud.com/connect?client_id=YOUR_CLIENT_ID&response_type=code&scope=&state=[random_string]&redirect_uri=YOUR_REDIRECT_URI
Accept the demand and this will redirect you to an URL with the code inside : code=YOUR_CODE. Keep it. If this is done by your customer, simply ask him to copy-paste the url.
That's not really secure, but you can't avoid it if your redirect uri is not accessible from Soundcloud.
Obtain a refresh token and an access token :
With curl, to keep your Client Secret, or App Secret, secret ( indeed :D ). And also the access token.
curl -X POST "https://api.soundcloud.com/oauth2/token"
-H "accept: application/json; charset=utf-8"
-H "Content-Type: application/x-www-form-urlencoded"
-d "grant_type=authorization_code&client_id=YOUR_CLIENT_ID&client_secret=YOUR_CLIENT_SECRET&redirect_uri=YOUR_REDIRECT_URI&code=YOUR_CODE"
This last request will answer in json format. Inside, you'll find an access token, and a refresh token.
Register the refresh token in your projet to reuse it to refresh your access token when needed !
I have created a job of JDBC to BigQuery using the web interface and it worked just fine.
Now I want to create the same job from the REST API of GCP so I took the rest equivalent of the request from the site and tried to send it from Postman.
I'm sending POST request for the following URL:
https://dataflow.googleapis.com/v1b3/projects/test-data-308414/templates:launch?gcsPath=gs://dataflow-templates/latest/Jdbc_to_BigQuery
which I got from the example in the GCP documentation.
I also pass the JSON that the GCP gave me in the body.
And the API key as get parameter in the next format "?key=[API_KEY]"
I'm getting 401 response from the server with the following message:
Request is missing required authentication credential. Expected OAuth
2 access token, login cookie or other valid authentication credential.
See
https://developers.google.com/identity/sign-in/web/devconsole-project.
With a status of:
UNAUTHENTICATED
I looked up at the link and found a tutorial on how to create google authentication on the front end
witch is not helpful to me.
I'm pretty sure that I'm passing the API key in the wrong format and that the reason it failed to authenticate.
But I couldn't find any documentation that says how to do it correctly.
PS> I have also tried passing it at the headers as I saw in one place
in the next format
Authorization : [API_KEY]
but it failed with the same message
Few days back I was trying to integrate GCP into MechCloud and struggling to figure out how to invoke a microservice ( which is acting as a proxy to GCP) with credentials for different projects which will be passed to this microservice on the fly. I was surprised that in spite of spending good amount of time I could not figure out how to achieve it because GCP documentation is focused on working with one project credentials at a time using application default credentials. Another frustrating thing is that API explorer shows both OAuth 2.0 and API Key by default for all the APIs when the fact is that API Key is hardly supported for any API. Finally I found the solution for this problem here.
Here are the steps to invoke a GCP rest api -
Create a service account for your project and download the json file associated with it.
Note down values of client_email, private_key_id and private_key attribues from service account json file.
Define following environment variables using above values -
GCP_SERVICE_ACCOUNT_CLIENT_EMAIL=<client_email>
GCP_SERVICE_ACCOUNT_PRIVATE_KEY_ID=<private_key_id>
GCP_SERVICE_ACCOUNT_PRIVATE_KEY=<private_key>
Execute following python code to generate jwt_token -
import time, jwt, os
iat = time.time()
exp = iat + 3600
client_email = os.getenv('GCP_SERVICE_ACCOUNT_CLIENT_EMAIL')
private_key_id = os.getenv('GCP_SERVICE_ACCOUNT_PRIVATE_KEY_ID')
private_key = os.getenv('GCP_SERVICE_ACCOUNT_PRIVATE_KEY')
payload = {
'iss': client_email,
'sub': client_email,
'aud': 'https://compute.googleapis.com/',
'iat': iat,
'exp': exp
}
private_key1 = private_key.replace('\\n', '\n')
# print(private_key1)
additional_headers = {'kid': private_key_id}
signed_jwt = jwt.encode(
payload,
private_key1,
headers=additional_headers,
algorithm='RS256'
)
print(signed_jwt)
Use generated jwt token from previous step and use it as a bearer token to invoke any GCP rest api. E.g.
curl -X GET --header 'Authorization: Bearer <jwt_token>' 'https://compute.googleapis.com/compute/v1/projects/{project}/global/networks'
The best practice to authenticate a request is to use your application credentials. Just make sure you installed the google cloud SDK.
curl -X POST \
-H "Authorization: Bearer "$(gcloud auth application-default print-access-token) \
-H "Content-Type: application/json; charset=utf-8" \
-d #request.json \

I am using Auth0 for User-Authentication in my VueJS-Application.
Now I want to create a backend providing a REST-API that will also use OAuth2-protocol and JWT-tokens in conjunction with our Auth0-based Frontend. This basically means: after SignUp of a new User, I want to send this new User to our backend in order to create a new record (which is already done).
The REST-API will be only accessible with a valid JWT-Token, which works perfectly following some tutorials and examples provided by Auth0 like this one.
I'd like to validate an access_token on my backend with Auth0 for a user, that was authenticated on the frontend application using auth0 also in the backend without sending any passwords.
This way, the Frontend or any other client can obtain an Access-Token like with this curl-command:
curl --request POST \
--url https://dev-xxxxx.eu.auth0.com/oauth/token \
--header 'content-type: application/json' \
--data '{"client_id":"DLjQxxxx","client_secret":"*****","audience":"https://api.example.org","grant_type":"client_credentials"}'
On the backend, I am able to parse this token against Auth0 to check if this token is valid or not.
But how can I obtain a token on the Frontend for a specific user consisting of its email and password in Auth0-authentication? The Auth0-API will not return any access token after user authentication that I can use together with my API in order to validate the JWT token for specific roles.
I think I don't get the final workflow here.
Can someone point me please into the right direction?
I am trying to make a request to the TaskRabbit API. I want to use my credentials and get the details of my account back.
I have a developer account (application ID, application Secret, Authorize URL). How can I use these credentials to authenticate with TaskRabbit? Can I use something like curl to test this out?
I tried using something like
curl -X POST -H "Content-Type: application/json" -d '{"username":"my username","password":"my password"}' https://combo-staging-2.taskrabbit.in/api/v2/account.json
this fails, since it’s not what the API expects. Is there a way to use my keys to make a similar request?
