How to Generate Shopify Abandoned Cart "key" Parameter? (Email Hash?) - hash

I’m looking at abandoned checkouts ion Shopify and hoping to create my own links. I see the Checkout object has a token to construct a URL like this:
shop.com/{{ checkout.id }}/checkouts/{{ token }}
That’s great. However, looking in Shopify admin I can see the links sent to customers also have a key URL parameter that seems to be some kind of email hash, since when you click on the full link, you are taken to the Checkout in a logged-in state… Since I have the Customer emails, does any one know how to create that hash?

The answer my friend, is blowing in the wind...

You can clearly see how to deal with that hash right there!

Is there a simple way to confirm something like a announcement using an email-ed link?

I've been trying for few days and couldn't really find answers about what I'm trying to do.
Take the example of a registration where a link to confirm your email is sent, and then when the link is clicked the account is confirmed.
I want to achieve this to do a kind of validation for announcement publication.
I tried taking the example of the symfony verify email feature, but in this case it's using the authenticated user when the link is clicked. In my case, the person clicking the link doesn't have an account on the website and shouldn't be authenticated.
How could the mail link, when clicked, change a booleon in the database, like 'is_confirmed' from 0 to 1 without needing a user authenticated?
Thanks
You're still going to need to authenticate, but you'll do it with a one-time token instead of a userid and password. For each message:
Generate a unique unguessable string, like a UUID v4.
Generate an expiration timestamp for however many minutes/hours/days in the future you want the token to be good for.
Save the token and the expiration timestamp in the db so it's associated somehow with the record in question. This might mean adding two columns to an existing table, or creating a new join table.
Generate an email to the recipient, including a link that has the token embedded in it, like http://example.com/approve?token=whatever or http://example.com/approve/whatever
Create the /approve page. Configure it to not require any traditional Symfony authentication. It should then:
Look up the token that was provided.
Verify that the associated timestamp isn't expired yet.
Perform whatever process you want to occur.
Wipe the token and the expiration from the db.

signature request API wrong url

When I do a Paypal API signature request under business profile, the generated api is using my old website ---whateverAPI.my-old-website.com
I've updated all of my business information and see no instances of the old url in my paypal account or the developer or sandbox accounts.
I do not have the old login information for developer area where I created the original API information as it was changed to my new login/business.
I need to change the URL associated with my account so the api generated has the apicode.new-website.com
I know this is a low level expertise for most of you compared to what you are coding but I am completely stuck and have tried everything I can think of.
Thanks for taking the time to read!
When the API is first requested on an account, it is generated based on the email address associated with the account at the time. Even if you remove the email address and request new API credentials, it will still use that original email address. There is no need for concern, you only set this in your API call or in your shopping cart to use. Buyers are not going to see it or anything, and it's not something you would regularly share or have to use all that often. Once you set it in your code, you don't really mess with it again unless you need to set up the API credentials again.

Roadblocks with using PayPal Recurring Payment Subscription with ASP.Net Membership?

I'm using ASP.Net Membership Provider for logging into the premium content of this web site. The content isn't downloads, it's web pages of information and discounts, etc. That part is done. We want them to also have a PayPal Subscription annual payment to see the premium content. I would like ASP Membership and PayPal Subscription to work together as much as possible, but for the minimum I am thinking they will have to create a MemberId before they pay. Then I will send that MemberId to PayPal to associate the two.
I think I can do that like this:
Set "Auto Return" on in the interface so that it will redirect to return URL when payment is made.
Set "return URL" query string to MemberId. This requires not using the precompiled "Saved" buttons. I'll have to set it in Code Behind with Name Value Pairs, "NVP" to PayPal. I was hoping to just paste the stupid button.
But then, there were those "Advanced Variables" in the Button maker. Problem was they are compiled into the Saved button, so I can't change them for each person. But maybe that one parameter could be separate from the compiled parameters? Is this better than hacking the return URL? Are "Advanced Variables" good for anything?
All the details about the transaction will be POSTed to the return URL if I put in the right code, which might be rm=2. (Right?) Then I can record it.
This process is said to be unreliable, though, and PayPal recommends using a secondary system that they have, "IPN". PayPal sends the transaction details to me. I send them back http 200 code. Then I send it back to them in the same order I got it. Then they send me http 200. Then we all know it's good. This sounds like a few hours research to me, but if you've already done it once, it sounds like copy and paste. I hate reinventing the wheel. Is there a .Net sample of this IPN handshake/dance?
Also, if I do the IPN thing, maybe I don't need Auto Return. Maybe I add MemberId to "notify" URL instead of "return" URL. Then PayPal can handle the confirmation page, email, etc. Is that better?
Assuming we get the Subscription paid for and recorded with the MemberId, at least once per user session, after they log in, I have to check if they have paid their PayPal subscription and if it's up to date. "GetRecurringPaymentsProfileDetails" does this, but it is an API operation. That makes sense, but I was hoping to avoid learning their REST API. (Is there a "NVP" version?)
REST API OAUTH tokens expire every few minutes, but the only way it tells to get one is by using "Bash" to "cURL" some Linux commands. Again, this seems like the kind of thing that would only ever have to be written once. Does this already exist as a sample code somewhere?
(I don't want to use the API to do the Subscribe, because I don't want the Credit Card numbers to ever go to our site. Too much liability. That's why I wanted PayPal.)
Will this even work? I know PayPal has 18 ways to do everything and they all exclude each other, and I'm just getting the feeling that I'm creating a patchwork of unrelated ideas to fool myself into believing there's a light at the end of the tunnel. I've already been researching and experimenting for 10 hours or so. I really thought, going in, I'd just be pasting a stupid button.
If you want to just "copy the stupid button" then you'll have to stick to Payments Standard, and then you'll be limited with what you can do. For example, you won't be able to use GetRecurringPaymentsProfileDetails for a standard subscription.
Instead, you'll need to use Express Checkout and / or Payments Pro. There is indeed an NVP API available for these, and there is also a SOAP/XML version. Details on those can be found here: https://developer.paypal.com/docs/classic/api/
Specifically, for Express Checkout, you'll want SetExpressCheckout, GetExpressCheckoutDetails, DoExpressCheckoutPayment, and CreateRecurringPaymentsProfile. Some of those calls are optional depending on how exactly you're configuring things with the checkout flow.
For Payments Pro you'll use either DoDirectPayment / CreateRecurringPaymentsProfile or PayFlow depending on what version they put you on.
In any case, IPN is definitely the way to go for post-transaction processing.

How to manage users account from multi-provider (facebook, twitter) in my website?

I'm about to use one of those multi-provider authentication frameworks Opauth or Hybridauth (don't know which is the best but I had a little preference for the second one) so the consequence is that I have to manage multi account.
In fact I already have my own account management (login+password+email) and I had last year facebook users. Now I will have to deal with Twitter account, linkedin account, etc...
So the question is easy : how to manage the username ?
For instance, John create a account on my site. So "John" login/username is taken. But if another John from Facebook then another one from Twitter arrive, what i'm supposed to do ?
In Stackoverflow (or elsewhere), what is the practice ?
I don't want a John write on the behalf of another John. Today with my own system, I verify that the login (username) is unique. If not I reject the user. But now ?
I thought that I can check the email but... I learnt that email address can't be the key because of Twitter that doesn't give it to you.
Hope I'm clear enough :)
regards
As you say it's not possible to just retrieve the username from different sources and just store it. I don't know how it is done here in stackoverflow but if you try to register the name is optional so probably it is not an unique key. I can't see the way to login with twitter here so I bet that email is a unique key.
I'll try to answer your question but I've only used facebook API so maybe this can't be done with others. I suppose that each API gives you something you can store in your database and use it later to identify your user against their API.
If you allow users to register with facebook (or gmail, twitter...)then you can use the next approaches (I'm sure there are few more):
They always login with facebook (or twitter, gmail...): you store a record for them inside your database with the key provided by the API and other useful info you can collect. As you said each API gives you different things so you have to think in advance what you really need to provide your users with a good experience: is their name needed? age? If you need more data than the provided by the API you should jump to the next approach or prefetch it and make it editable before. Here you don't ask your user for a password so they can only login with facebook not with a login form, if a user tries to authenticate with facebook (or twitter, gmail) again you know which key you have to look for and authenticate your use.
The can create an account and link it with facebook (or whatever): you ask for facebook permission and then prefill a form for them to provide the data that is missing (password, mail if they use twitter...) and then create the record storing the unique key provided by the API as well to proceed exactly as step 1 if they use their facebook accounts to login. If you asked for a password and an email they can use a standard login form as well.
You can use the first approach and ask the user to change the attribute that is in conflict with other user (name in your case) or even ask to fill what is missing depending on which social network they are using to sign in. You can use name+surname as username to reduce the colission possibility if this is what you want to store to identify your user.
Hope this helps
HybridAuth gives you an excellent way to integrate your site with the social media...

Forwarding to Paypal with GET

i usually use the standard POST form on my site, with fields that the user fills out, which POSTs directly to https://www.paypal.com/cgi-bin/webscr
what i would like to do now, is have the form submit to my own site, for my own internal programming purposes, and when that is done, my site would automatically forward the user to paypal, with the relevant field data in the URL, for example, to: https://www.paypal.com/cgi-bin/webscr?first_name=foo&last_name=bar& etc...
this would save me from having to put the intermediate stage of the form with the hidden fields, asking the user to "click here to complete your transaction on PayPal"
hope i'm understood....
thanks!
Sure, it'll work. But keep in mind that unless you involve the BMCreateButton or Express Checkout API's, the amount will be open to URL manipulation, so you must do a check on the paid amount afterwards.
For example; https://www.paypal.com/cgi-bin/webscr?cmd=_xclick&business=blah#blah2.com&amount=0.99&currency_code=GBP&item_name=Blah+for+sale
Note: The GET redirect must be initiated on the browser-side or via a header() redirect. You can't use cURL for this, since that's a server-to-server communication.
