File Exchange migrate to Feed API without OAuth in eBay - ebay-api

How can I use bulk data exchange using only auth'n'auth token.
My application does not have the ability to use OAuth because it works without users in the cron job.
Any ideas or examples?

Clearly there's no solution since service has been dismissed.
You can try with some SaaS solution.

You can create a RefreshToken which you can use for 18 months.
with this refresh token you can create your OAuth access Token und use the sell feed api

Customer Authentication in commercejs

You get the problem reading the title. Is there anyway I can sign up customers using commercejs. The documentation is only showing login/logout methods but not sign up.Is there anyway I can do it through commercjs. Or should I use other authentication service like Firebase Auth??
There is no specific way to register a user as Commercejs does not store any kind of password.
The only way for registering a user is to use https://commercejs.com/docs/api/#create-customer as per API reference docs. however if you want to integrate some kind of custom auth you should definitely use this reference:
https://commercejs.com/docs/api/#issue-jwt-for-customer
This allows you to issue a JSON web token for a customer directly using your secret Chec API key. This may be a desirable option if you are integrating your own customer authentication, and simply need a token to authorize API requests as your customer with.
I have personally used this method along with Firebase auth.

How to restrict someone to access my API directly using www.my-appspot-id.appspot.com/_ah/api/explorer?

I have created an app and some REST API on Google Appengine and deployed it to
www.my-appspot-id.appspot.com
I'm using Google Datastore to store my data and have created API's to access that data.
However, i can access my API directly also using
www.my-appspot-id.appspot.com/_ah/api/explorer
which means anyone can access them and can manipulate the data which i don't want.
How to restrict access so that nobody but some particular registered set of users can only use it?
I stumbled upon this tutorial recently, might be of some help.
I think you need to authenticate your endpoints and authorize only some client id.
OAuth 2 authentication : https://developers.google.com/appengine/docs/python/endpoints/getstarted/backend/auth
Allowed client ids and audience : https://developers.google.com/appengine/docs/python/endpoints/create_api#allowed_client_ids_and_audiences
To answer your question : you can't.
Google Cloud Endpoints is based on the explorer api: everybody will be able to navigate into your API, and see the differents methods available.
BUT if you add an authentication to your methods, the visitor will not be able to execute them.

Smartsheet API Sign in.

Is it possible to use Smartsheet's API to sign into Smartsheet on the Web. I am thinking of creating a form-based auth that uses the API to login. Has anyone done something like this? or is this even possible with the tokens that can be produced by the API. I am aiming for a web based single sign on without using SAML.
I'm not totally clear on what you are asking, so I'll address each question individually in hopes that it addresses your overall question:
Is it possible to use Smartsheet's API to sign into Smartsheet on the Web?
No, you cannot create a web session using the api. For 3rd party apps, that would defeat the purpose of using OAuth2 since the whole goal with OAuth is to grant limited access to protected resources. For user-generated access tokens, it could be feasible, since those tokens have unrestricted access, but the API does not currently support that.
I am thinking of creating a form-based auth that uses the API to login. Has anyone done something like this?
I assume you mean you will create a form to collect a user's Smartsheet credentials and use those to have an SSO experience into Smartsheet? This is technically possible, but I'd strongly discourage against it. To create an SSO experience, you'd need to retain the password in a way that allows you to POST it on behalf of the user. This means you'd store it in a 2-way encrypted state (at best), which is definitely not best practice. Again, I'd highly recommend NOT doing this.
I am aiming for a web based single sign on without using SAML.
If you want an SSO experience into Smartsheet, you can either use SAML or Google (not truly SSO, but pretty close). There isn't an API-based approach currently.
Side note, if you want to go the other way, meaning you have a website and you want to use Smartsheet (or any OAuth2-based API for that matter) as the identity provider, you could use the 3rd Party OAuth2 flow. See the docs here. You could then add a "Login with Smartsheet" button to initiate that flow, much like we see everywhere on the web with "Login with Google" or "Login with Facebook".

How to make twitter api calls using access token

I have managed to get an access token from the twitter api. Now I want to use that token for my further data fetching things, so please help me here to get the details of my twitter account.
For example, lets say I wanted to get the user's data, so when I tested this in apigee console, I got my result.
But how to get the same result, using same api, by hitting on a browser using the access token
something like this
Please help
It's a little more complex than the URL you suggested, but you can use Twitter's OAuth tool to generate the OAuth signature you need to make requests to its Home Timeline API call.
You can find the OAuth tool here:
https://dev.twitter.com/docs/api/1.1/get/statuses/home_timeline#oauth-tool
it's not like that when making twitter api calls you need to send consumer key, consumer secret, your_access_token and your_access_token_secret together
Eg: oauth_consumer_key="KEY",oauth_signature_method="HMAC-SHA1",oauth_timestamp="TIMESTAMP",oauth_nonce="NONCE",oauth_version="1.0",oauth_token="YOUR_TOKEN",oauth_signature="SIGN"

BigQuery Simple Api Authentication

I am trying to gain access to my BigQuery enabled Google API project using the .net Google APIs.
Using a console application, I am trying to authenicate first by supplying my simple API key in the URI, then just trying to get the list of projects.
The error I am receiving when I call Fetch() on the project list is: Login Required [401]
var bigqueryService = new BigqueryService{ Key = "MY-API_KEY" };
var projectList = bigqueryService.Projects.List().Fetch();
I am purposefully not using OAuth2 as we don't need any user data.
The API key simply identifies your app to the API console for quota purposes and other housekeeping. It's not authoritative for accessing BigQuery, as we do consider the BigQuery data as "user data."
If you're just trying to get an OAuth 2 access token for playing around quickly, you can use the OAuth 2 playground:
https://code.google.com/oauthplayground/
This token will be valid for one hour and can be copied/pasted as the access_token query parameter
Here's the scope for BigQuery to use in the playground:
https://www.googleapis.com/auth/bigquery
In the end, you'll either want to use the native client (out of band) flow:
https://developers.google.com/accounts/docs/OAuth2InstalledApp
Or the server-to-server (service accounts) flow:
https://developers.google.com/accounts/docs/OAuth2ServiceAccount
I don't have quick samples handy for those in .NET, but post another question on SO if you can't find them-- I'm sure someone will chip in!
You won't be able to use a simple API key - all authorization to the BigQuery API must happen via user interaction, or alternatively through a service account.
