I am new at paypal payment system...
I have seen this been done, but i donn't find PayPals Documentation user friendly...
I need to make a payment gateway system, to allow users to use a shopping cart... then they could pay the total through paypal...
so is there a way to use paypal api tell how much the user should be charged e.g: $100 or £100 or however the product(s) might cost?
then confirm it... or if there is a tutorial (for newbies/dummie lol ) would be a great help.
Also which paypal option/system am I looking to use on this occasion.
hope i have explained myself clearly... thank you .
I can use PHP, and MySQL, JavaScript/JQuery, if necessary and I am confortable with understanding them.
(BTW PayPal is the worse documentation i have ever come across lol)
yes paypal can use a authorization & capture solution.
You can use GetExpressChecout with setExpressCheckout.
A good solution is to use a DoReferenceTransaction with theses method, in order to use recurring payment.
I have some sample but in c#.
The API ref :

Im trying set up recurring payment on my site by using Paypal Express Checkout. I did read through the official docs and I couldnt find anything useful related to recurring payment.
https://developer.paypal.com/docs/integration/direct/express-checkout/integration-jsv4/add-paypal-button/
Im just wondering does Express Checkout support recurring payment? If so, how can I achieve that or Where can I get some good example to start with?
Thank you for your help in advance. Much appreciated
Cheers
We have a similar issue before. You might wanted to take a look at this thread.
I'm trying to understand the use case here. When you say recurring payment for express checkout,it has to be something a customer is buying regularly like restocking an item, in that case it's not an express checkout, it's a recurring purchase by a returning customer. They must have opted to restock at a regular interval like every 30 days, 2 months etc. They also must be registered users on your website.
So your logic must include — Checking all the customers who have set up an automatic purchase for an item.
—Check their frequency of purchase and charge them for the amount of the item at that frequency.
—For this purpose PayPal has a REST API :
This is the accurate place to look for to implement PayPal recurring payments:
https://developer.paypal.com/docs/api/payments/#payment_create
In case they also allow you to authorize payments through the following API
https://developer.paypal.com/docs/api/payments/#authorization
you could use it as well.
But at least this narrows down your choices in terms of regular payment authorization.
This API will allow you to request PayPal services to authorize payment on a regular basis for that customer. You will still have to have your own logic to check the 'subscription' for your products and the intervals.
—The CreateRecurringPaymentsProfile API Operation (NVP) at the link below looks to be for personal payments. For example something an Inventory Management System will do.
https://developer.paypal.com/docs/classic/api/merchant/CreateRecurringPaymentsProfile_API_Operation_NVP/
It's an API specific to adding recurring payments functionality.
Since you're a developer, PayPal Developers' Resources will answer any queries you have regarding the API functionality and usage. You will have to just know what to ask for. You are their B2B customer trying to understand their API system. You can also file a bug on their Developer portal if you're not getting proper answers.
I need a help regarding paypal.
That is. Once I have logged in with paypal and made payment, Then for another payment no login will be asked, Direct payment will be done using paypal. Please comment your suggestions. Thanks in Advance.
You have a couple of options for this.
First, you could take a look at Preapproval, which is part of the Adaptive Payments platform. It allows users to create a Preapproval profile that your application can then use to trigger payments at any time without further approval as long as the payment fits within the guidelines of the preapproval profile.
Another option would be to look into Express Checkout with Reference Transactions. This would give you a little bit more flexibility and would be more in line what you're asking for, I think. Users would agree during their first payment with you to allow you to auto-charge this same account in the future. Then you would use DoReferenceTransaction to trigger future payments based on that "billing agreement" which is what it would be called that way.
I would recommend going with Express Checkout, and you might want to look at Digital Goods, too, which just adds some more functionality with quicker PayPal checkout in various ways.
It's all handled through a few simple API calls, so don't let all the info scare you.
My PHP class library for PayPal will make all of the API calls very simple for you regardless of which method you choose. Again, though, I'd recommend Express Checkout.
I'm using paypal to make my users able to payout their credits, which they can earn on my site. So i am actually buying my users efforts. As i have up to 200 payments per month, i would like to know, is there a possibility to send payments to my users via paypal api?
If yes, which methods should i use and what should i take care of? I possible i would also take a ready to go implementation in php.
I tried to check the documentation of the paypal api, but it was to complex, so i did not find any solution.
If you'll be submitting payments to 200+ people at the same time, the MassPay API would work nicely for you, but you'll need to call PayPal to request it and get it specifically approved on your account.
If the users will be doing this on their own, one at a time, then you'll want to look at the Pay API, which is part of the Adaptive Payments platform.
You can use my PHP class library for PayPal to make the API calls very quick and easy for you regardless of which method you end up using.
I developed a Web Application that accepts payments via the ExpressCheckout API, for users to become a members.
Everything works fine.
I now want to extend my Web Application Services and offer my users with the possibility to buy items which are sold by third parties (my members).
The principle I would like to implement is quite simple: for each order, let the user pay for the item they choose and then transfer a part of the amount I received to the item provider, and keep some money for me. I would like to automate this process so that once I received the payment notification, I compute the amount of money to transfer to the item provider who might or not have a Paypal account (in other words, this means that I could maybe need to transfer the money to a bank account, using the IBAN/SWIFT data) and then proceed with the money transfer.
I tried to find a solution reading your documentation and came across the "chained payment" but the latter does not seem to be used within the ExpressCheckout workflow.
Also, since my implementation of the ExpressCheckout flow works, I would not like to have to find a totally different solution but rather extend it... if possible.
Could you please tell me which is the best solution for me?
In advance, many thanks for your help.
You could do 1 of 2 things. You could use Express Checkout with parallel payments. This means you could split the transaction up between different accounts at the time of purchase. The other option would be to just receive all of the funds into your account, and then when you are wanting to send money to the other accounts you could either use the Adaptive Payments (Pay) API or the MassPayments API to send money to the other accounts. Keep in mind you would have to send it to their PayPal accounts, you would not be able to send it directly to a bank account with either one of these API's.
I had the same issue and I got an answer from PayPal that it is not allowed to use Express Checkout to transfer money to your PayPal account and - at a later point in time - transfer the amount minus your service fee (which stays on your PayPal account) via Adapative Payments API to the seller's PayPal account. PayPal suggested to use Chained Payments API instead. All works fine in the sandbox, but once you need a Live APP ID from PayPal they will review your business case and deny it. At least that what happened to me.
I know that is old question, but anyway, I tried to find solution and was enable to perform the simillar thing like described in question. So, then I asked paypal about this, and they gave me advice to use SellerDetailsType Fields that 's called PayPalAccountID, description for this field is Unique identifier for the merchant. For parallel payments, this field is required and must contain the Payer Id or the email address of the merchant. It wasn't clear for me to use this field for solving my problem. Here is link https://developer.paypal.com/webapps/developer/docs/classic/api/merchant/SetExpressCheckout_API_Operation_SOAP/ I described field for soap request, for NVP it's called PAYMENTREQUEST_n_SELLERPAYPALACCOUNTID, but the idea is the same. I hope it will help someone.
Well, I didn't really know how to call this...
I have been surfing PayPal's developer documentation for a while now, but there is nothing that speaks to me with direction as to achieving what I am looking for.
It's probably well documented, but I don't grasp it well enough yet to make sense while reading each part separately.
I have read about Preapproval, though it seem to require that I send the customer's browser to the designated PayPal address.
I have thought about creating a database with credit card information, but that is too scary -- so I am looking to see if there is a way for a customer to allow me to do unattended charges to their PayPal account, much like I would be able to do if I had a database with customer credit card information.
Any direction would be appreciated.
Yes, this is possible. There are two options:
PayPal Express Checkout with a Billing Agreement
This works similarly to Preapprovals (which is Adaptive Payments, a different set of API's). You would need to redirect the buyer to PayPal in order to accept the billing agreement, and from then on you can bill the user using to DoReferenceTransaction API.
PayPal DoDirectPayment (Website Payments Pro) with Reference Transactions
You would need to have an existing transaction, and instead of a billing agreement ID, you would submit a prior transaction ID to the DoReferenceTransaction API. You can then re-bill the user on the card details which are stored with PayPal (up to 1 year. assuming the card details are still valid).
Do note that both options require you having access to the DoReferenceTransaction API, which you will not have access to by default.
For further information on the API itself, see https://cms.paypal.com/us/cgi-bin/?cmd=_render-content&content_ID=developer/e_howto_api_nvp_r_DoReferenceTransaction
Important: You will need to call in to get Billing Agreements activated. Good luck finding someone that knows what you need (no really) :-)
You will eventually find someone who knows what DoReferenceTransaction is and then once you've finally found them they'll probably tell you they can only activate it in the sand box and transfer you to someone in the Business Office. They'll have to then submit it to approval with someone else. Est. Total call time 59 minutes 8 seconds.
The guy I just spoke with said he's probably handled only 2 call in a year about DoReferenceTransaction - so you may need to ask around. They have other subscription billing and that's not what you want.
Also realize that approval is not instant and you may need to have established history. The guy who helped me said this is the best number
888 215 5506. Be sure to explain why you need them carefully and try to reassure them you're legitimate. A reputable website behind the domain for your paypal email will probably help.
Good news: I applied for Reference Transactions Friday and was approved today (Sunday). This was for two accounts - one which had only been established the day before.
Thank you for contacting us about enabling reference transactions on
your PayPal account.
I am pleased to inform you that your request has been approved. You
can begin using this feature immediately.
If you have further questions regarding this email, please contact a

I was trying to do this recently and I found this question with no luck because the Express Checkout with a Billing Agreement method is deprecated since January 1, 2017.
There is a new REST method called Vault payment methods that recently entered open beta and it's not in the official documentation (to this date), so I leave the link to Create transactions when your buyer isn't present, in case someone needs it.
The process it's explained in the documentation but basically, you need to create a payment token (the source can be a PayPal account or a credit card), and then use that token to capture the payment.
