Instagram Login - authentication

I'm new to the Instagram API and I am very interested in using it to create a login for a site I am building as another option for the user to get access. I've had a brief look at the documentation but still have no real understanding on how this could be achieved. Any help/links/documentation would be very helpful.

Did you see this documentation? It is really spot-on so I would recommend taking a look and then if you still have specific questions about it just edit your question and I'll see if I can answer them.

How to find the **alwasys** up to date Facebook Login API Worlflow URLs

This is additional question in regards to another relevant question:
Facebook Authorization url, scoped authorization url and token url
, I am new to OAuth2.0, so assume I didn't learn literature well back in high school!! (I have seen some people with very short learning curve recommended to read the Facebook login API documentation)
I have looked at it, but didn't find the
Authorization URL
AND
Access Token URL
While I was searching for some demos, in one video it used
https://www.facebook.com/v6.0/dialog/oauth?
key being: v6.0
in another it used:
https://www.facebook.com/v15.0/dialog/oauth?
key being: v15.0
and in the original post, the kind person who answered seemed to suggest to use:
https://www.facebook.com/dialog/oauth
(which didn't mention the version ID at all, that worked for me, and I like it; easier to remember and use. HOWEVER, previous two also kinda make sense, I don't think Facebook gonna stop enhancing and upgrading its OAuth2 APIs.
and if I go back to the original question, how can I find the latest URL info for above mentioned endpoints?
Thank you a million in advance!!
if this question was too basic, please be tolerant, I am new to OAuth2.0!

Can I track if someone clicked a link on my Twitter post

I have a private business Twitter account and I would like to know when someone clicks any link inside one of my posts. This solution cannot assume that we know the form of the link being posted.
For example a twitter post like this:
Have you guys heard of this amazing site called google?
I would like to see how many people clicked on this google.com link. I don't need to know any specific information about who they are, just if it was clicked or not.
Ideally I would want this from the API but crawlers and plugins are also possible. I would like to avoid using a paid tool but those would be acceptable.
I think you have multiple choices:
Use google firebase or google analytics
Create your own short link services by python or any other programming languages.
Just search in the google and look for short link generators which gives appropriate service.
Hi using the twitter api you should be able to understand how many clicks a link has.

But to have all this info automated you might need to use a third-party tool.
This should be the most straight forward solution.

Getting access to the Google Pay API for Passes

I am currently trying to get access to the Google Pay API for passes. I am following the official guide provided by Google: https://developers.google.com/pay/passes/guides/basic-setup/get-access-to-rest-api
Unfortunately I can't even follow the first step, as the sign up form for Google Merchant seems to be offline. The URL where I expect the form just forwards me to an FAQ page.
Has anyone had similar issues lately.
Any kind of help or information is appreciated! Thanks.
Moving discussion from comment to answer to include image.
Hard to say if we're seeing the same thing. This is what I see when visiting https://support.google.com/pay/merchants/gethelp?visit_id=1-636549173956235486-3194546471&rd=4
Is this what you see?
You need to go straight to step 2. Access the API Console.

Post Content on Google+ Business Page - SEO

Is it a good idea to directly post content on google+ business page instead of sharing (adding) the link of a blog written by us?
Right now, the blog cannot be setup in the website. So, will posting informative content on google+ business page will be a good idea?
Dear
Maybe suggest to your client its done on a sub domain and even hosted elsewhere so blog.yourdomain.com
This have a couple of benefits, firstly google will know the blog is part of the site so credit it with the new content.
But one other thing is that if the blog is hosted elsewhere should there be a problem with the main site for what ever reason the blog would still function giving you a way to communicate with your users.
Its always nice to have a fallback solution and maybe offering them that might help.
good luck
Posting content to G+ is good idea. But you have more control on your own blog. Let's imagine some scenarios: 1. Google shuts down Google+. 2. Your content don't meets Google policy.
