How Google Pay figure out user's payment methods? - google-pay

Does Google Pay use Google Account's session cookies to figure out which payment method user can use?

Google Pay payment methods are attached to a Google profile and available when logged in.
On the web, if the user is NOT logged into a Google account when initiating a Google Pay payment, the user will be prompted to log in.
Cookies are involved in maintaining authenticated user state.

Auth0 Guest user login and Rest API login

Lately I started looking into PoC with Auth0 for our use case where we want to allow users to login with Google and Facebook, also want Guest user to login and access our API and once guest user choose to login with Google and Facebook then we can link guest user so that their data will be served once logout.
Here's the things which I am to able to do till now with PoC:
Able to Login with Google and Facebook through client App.
Access authenticated API after getting bearer token from client App.
Things which still need to do, I tried to search but couldn't found good resource:
I want user to login as Guest user and latter if they want they can login with Google/FB and link their account.
Also, I am looking into Rest login API in Auth0 so that we can hit login API after getting access token from Google/FB and register user into Auth0 and get the token for API access.
It would be great if anyone help me on above two points. Thanks!

PayPal sandbox for testing - is it safe?

I've been working with PayPal's Adaptive Payments API for a while and i'm ready to begin testing of my website.
My plan is to create a bunch of PayPal sandbox accounts and give them to family and friends to use on my site.
However, I've noticed that when I log in to a sandbox account (at sandbox.paypal.com), it says 'Logged in as real-account#example.com' where real-account#example.com is my actual PayPal account.
Does logging in to the fake sandbox accounts give the testers access to my real PayPal account?
No, it doesn't. Your real PayPal email address shows up at the top of the page because that's what you used to sign into https://developer.paypal.com, and there's a cookie on your computer telling the Sandbox that you signed in with that email address. It won't show up for other users.

Is there a way to verify social media links of a user

I am project owner of a community application built on Ruby on Rails: My question is about social network verifications.
We ask the user to add his/her social media profiles to his public profile of the community.
At the moment the user can simply put e.g. his/her Facebook URL to his profile, same for pinterest profile, Twitter and so on, but there is no validation for the urls, at the end of the day the user can add anything he wants, also blablabla
Is there a way to verify if his/her entries are valid?
Token, API, validation test?
Any hint is welcome,
Thank you
Most Social Networks have APIs and you can ask the user to link his account on your application to his/her account on a specific network if he/she wants to show profiles on these Networks.
For Example, you can use the Ruby Koala gem to communicate with the Facebook API. You can create a Facebook Application and link it to your website, then ask the user to grant your Facebook App the minimal default permissions, these will be sufficient to get the Facebook profile URL of the account that was acutally linked, i.e verified.

Can I let test users skip logging into PayPal sandbox?

I am using the PayPal sandbox to test user transaction on my website.
The site is going to be put through usability testing soon.
The problem is, whenever a user goes to complete a transaction, they are first asked to "Please login to use the PayPal Sandbox features."
This is the link that my form points to: https://www.sandbox.paypal.com/cgi-bin/webscr
I want the test users to skip having to create a PayPal sandbox account and just use the test user accounts that I have setup.
Is this possible?
This is not possible. A user has to have a developer account created at developer.paypal.com to be able to use any PayPal hosted payment methods on the sandbox.
However, you can submit API calls to the sandbox without the members needing a developer.paypal.com sandbox account.

Linkedin API: how to use my login credential in my access token

I'm building my website to pull out my own linkedin profile info. And it is working but when a visitor comes to the site, they will have to login to see my profile info displayed on my page. This should be a public website and I don't want visitors to log in to their linkedin account in order to see my public page.
Is there anyway to do this (so that visitors can see my info without having to be logged in) ? Thank you
NOTE: I'm using their REST API by the way.
Simple code
Per the documentation (section #1, bullet point 3), it is not possible to share your profile information via the API without the user both authenticating your LinkedIn application that is pulling the info, and also the authenticated user then being connected to you in some way. From that document, "Each user must grant your application access to their LinkedIn network and they can only see data from their own LinkedIn network. For example, you cannot gather information about a LinkedIn member in one user's LinkedIn network and show that information to other users"
In short, the REST API is probably not the way to go to expose un-authenticate user's to your profile. What you might want to do is use one of the plugins, such as the Member Profile plugin.
