I have looked around SO for this but I can't seem to find anything like it.
On my service, I wish to charge on a per-month basis depending on how many users my clients have.
So this question is split up into two parts.
What I want to know is it possible for a client to use their own paypal account (without entering any CC details) with conjunction with CreateRecurringPaymentsProfile via the NVP, I have looked through the documentation and can not discern anything. So clearly it is not possible to do it via NPV - From what I've seen so far.
i. If I do an Express-Checkout Subscription, I can do 20% change on total amount every 180 days (I DO NOT want to do this) - I want to be able to get the Profile via the IPN and then modify the monthly amount on as-need basis
ii. There was some mention of Referenced Transactions, but the Documentation is very confusing.
So say there is a way to create a recurring payment subscription via a PayPal Account on the PayPal website, next step is to be able to update the Subscription via UpdateRecurringPaymentsProfile NVP command.
While I am happy to pass on CC details (which already works great), I am just wondering if it is indeed possible create a button, which would create a Subscription - once on success an IPN request is sent back with the ProfileID which I can modify the Billing Amount by NVP.
So TL;DR;
The current flow I have
Register on our website
Enter CC Details
Backend submits the data to PayPal and if passed - continues on.
On any Account modifications, update Profile Monthly Amount Automatically.
The flow I want
Register on website
Click on an Authorize Button Redirected to PayPal
Login to their PayPal Account Create Recurring Profile.
On any Account modifications, update that Profile Monthly Amount Automatically.
edit to add - this is all working now, had to contact and harass PayPal directly for a lonngg time.
I'm a little confused because it sounds like you answered your own question, but then said that's not what you want..??
Express Checkout does exactly what you outlined at the end of your post, and it triggers an IPN just like any other PayPal transaction. You are indeed limited on how much you can adjust the amounts of profiles created with EC, though, just like you mentioned with the 20% every 180 days. If you create profiles with Payments Pro (DoDirectPayment or PayFlow) then you're not limited and you can adjust the amounts however much you need to whenever you need to.
Reference Transactions and Preapprovals may be something to look into as well. I actually wrote an article about what they are and how they differ from each other awhile back that you might be interested in.

In Paypal, I m trying to implemen t a Auto payment system using paypal. Where user can save their card details then whenever the invoice is generated using card details invoice can be paid automatically.
I read the document of paypal but not found regarding that.
Please let me know how can I implement Auto payment system using PayPal.
There's quite a bit of information on the Subscriptions page, but most of that is a generic overview. However, there is link to the Integrate Subscriptions page that gives more links to specific API and SDK instructions.
Follow through the step-by-step information to get all this set up. It'll take a while to get everything correct, so definitely use their testing APIs so you aren't doing a bunch of tests on their production APIs and spending your own money doing it.
Once you get the subscriptions created and someone subscribed, PayPal does the rest. You just need to create the subscription and allow people to subscribe.
Also, PayPal keeps track of credit cards and other payment forms for you, so you don't have to go through all the PCI security procedures for storing that information yourself. That gets real involved and can cause you to get in serious trouble with fines and lawsuits if you aren't certified. It's much easier to use a payment processing gateway such as PayPal for this than create your own, especially since you are going to be using PayPal for processing the payments anyway.
I would like to support payments in my web application which acts as proxy between group of customers and merchant. I'm still trying to research this, but I'm new to subject and a little confused. Maybe someone could point me to good direction.
Is below scenario possible with paypal services (or other similiar sites)?
Customer creates account and my application stores his billing data
(credit card number) in 3rd party service, so I don't need PCI
compliance certificate
Customer A, B and C are creating common
group order from one of registered merchants. For example there are
3 products in this global order.
After some time one of customers
accepts group order and application create 3 payments to merchant
without needing confirmation from all customers
Those orders will be daily and payment will be delayed so that's why I don't want confirmation from users.
I was reading on Paypal site about Adaptive Payments, but there is step "Redirect the Customer to PayPal for Authorization", so I assume it's not for me, because it needs confirmation.

I'm from Poland so Paypal Direct Credit Card Payments are not available for me.
https://developer.paypal.com/webapps/developer/docs/integration/direct/rest_api_payment_country_currency_support/#direct-credit-card-payments
I found REST operation - store a credit card so maybe one thing is easy :)

Let me see if I can answer your questions (I'm with PayPal / Braintree), and I'm perfectly fine with you asking it here.
The short answer to your question is that yes, this is absolutely possible with PayPal services. Let's break down each part with some options:
Storing billing data
It looks like you already found the answer here - you can absolutely use the vault for storing that information (https://developer.paypal.com/webapps/developer/docs/integration/direct/rest-vault-overview/).
Creating an order for later capturing & Capturing the payment
What I would look into here (to see if that works for your needs) is the auth-capture mechanism (auth: https://developer.paypal.com/webapps/developer/docs/api/#authorizations and capture: https://developer.paypal.com/webapps/developer/docs/api/#captures). Here's how it basically works:
- You use authorize to hold funds in the buyer's account for a period of time.
- From the auth you will get a key back that will allow you to reference that authorization in the capture step
- When you are ready to capture, you simply use the capture endpoint with that key, and you capture those funds.
There's also on other mechanism which you might want to check out - the orders endpoint adds more of a flow on top of auth / capture to allow you to have auth / capture more bound to a order processing - you can check out more on that here: https://devblog.paypal.com/rest-orders-api/
A few other notes. There are a whole series of products in the classic suite to also do 2) and 3). One of the best resources I like in the classic docs is the use case page at https://developer.paypal.com/webapps/developer/docs/classic/use-cases/ - it tends to help guide you based on real world scenarios.
I hope that all helps, and I'd be happy to follow up with more specifics if there is something that I missed from your scenario.

I'm using paypal website standard and passing my order id that is generated on my site via item_number field. I was wondering, how does paypal know that the content in the form has not been altered by user? For example, someone could just change the amount of $10 to $5 and paypal would not not have any way of knowing. I've doe this before with other payment processor, and they make me send them md5 hash of amount and some other data + secret key, but I am not sure if paypal has this?
Based on this article, I believe it depends on whether or not you are using "Payment Data Transfer". If you're just using a button, then you'll need to manually verify the payment amount before shipping. If you're using PDT, you should be able to verify the payment_gross amount sent back in the response from PayPal.
Your right -- in general you can't keep someone from altering your data. If you must use PayPal (yeah, I know, no monthly fee) so far as I know you have three options:
Let PayPal host your button data. But this gives you little control over the process.
Manually verify each transaction, checking price etc before shipping item.
Using their API to receive completed transaction to automatically check data.
Another thing to watch out for is calculation of sales tax. PayPal's approach was too simplistic for our needs, which forced me to take control of the checkout process.
See this link.
you should try to implement it using ipn, pdt is prone to not passing the variables from paypal to your website if the user does not press the "go to store" button. as what others had answered hosting your button would make it secure at the cost of flexibility. Here is a link on the variables that could be altered on hosted buttons https://www.x.com/people/PP_MTS_Haack/blog/2009/11/11/override-variables-for-hosted-and-encrypted-buttons , as you would look into the variables, you cant really change the important ones.
The payments we gather on our website are for online subscriptions and registrations for conferences. In both cases, we want to gather absolutely all information other than the payment information ourselves, and ideally pass some of it on to PayPal (so users don't have to fill in name, address, etc. twice).
I know there are solutions where the information is gathered by the server itself and then redirected to PayPal via a web services call but that's not an option, unfortunately. All secure payment information gathered has to happen off-server due to network policy.
In addition, not every form will need to be processed using PayPal. Some people will be paying via check, etc. so they shouldn't be sent to a payment page at all. Most solutions I've looked at have a "Pay with Paypal" button, so I assume a form post is necessary to go to the PayPal site, but ideally we'd want to get there via a 302 redirect. Is that at all possible? (I'm aware we could do something like a form that was auto-submitted by JavaScript but I'd prefer to not go down that route).
Whichever system we implemented would need to handle recurring (periodic) payments also.
Paypal has something called Payflow Pro. They bought it from VeriSign a few years ago.
You can use it to do a full integration with the paypal api. So that the user enters their payment details on your site, and your backend code submits the transaction to paypal's servers. Paypal will then give you a transaction id back. Keep the transaction ID, chuck everything else (like the card number) out the window.
We have several clients that use Payflow Pro. It's very good and easy to use api.
I'm not entirely sure I understand the full scope of your question, but I think I do. I've coded a number these conf. registrations (though I have not interfaced with PayPal...rather iTransact and Plug'NPay) and in my applications, I had to read through the API documentation for the system being used (PayPal in this case). Then I logged into the payment gateway and usually they have an html form generator. All this does, of course, is returns an html form with the fields labeled appropriate to their API (so the billing name and address carry over from your system to PayPal's and the user doesn't have to re-enter their information), shows you what hidden fields you'll need(like cutomer_id, etc) and the form POST path.
Then what I do is I have the user register, preview their order details on another page (where you can choose to drop their info into a DB or wait until AFTER their credit card is processed) and then upon confirmation, they go to PayPal, pay with either credit card OR check (the options always exist) and when they hit confirm, the passback URL you put into a hidden var somewhere, takes you to a custom Thank You page (and hopefully processing script to capture successful transactions) which can be hosted anywhere on your servers.
It's pretty simple, just a bit labor intensive at first as you try and figure out the new form variables specific to a payment gateway API.
Hope this helped!
I'm trying to integrate a payment mechanism to my site. The scenario that I need is not trivial and can be explained by the following example:
User pays upfront for a subscription program (i.e. receiving Netflix). User is able to make changes to the subscription (i.e. change number of movies checked out each time from 4 to 2)
User is able to buy additional one time purchases via the provider's site (Netflix) supplied by 3rd parties. These items (i.e. popcorn, snacks) get billed to the same credit card as the subscription without having to go through the process of resubmitting the credit card information.
Of course, my site takes also a small fee for the transactions :-)
I was wondering if this is supported by PayPal, Google Checkout or someone else.
Thanks.
The Paypal api can handle all of those processes.
I seem to have dropped the ball on what kind of answer you wanted so I'll leave it at that.
If you have some feedback, more direct questions I will try to answer as much as I can
--
The money would best go through you first, unless somehow you can convince your customers its normal to bill them per item. Also if they pay by credit card you should only bill them once as you would incur fees on every payment. I don't know of anyway to bill once but distribute the payments.
As for the paypal docs..
Very good resource, there is also some sample code for most major web languages
Also this will get you started if you don't have a developer login
Their developer support is also pretty good. One thing a lot of people seem to screw up when starting out with the paypal api is not setting the latest version in the configs so don't forget to update that to the latest release. :)
Disclaimer..
Yea I know there is a lot of bad press about paypal and crazy stuff happening, but they do get the job done most of the time, its not my fault the customers love to use it.
