I am working on the paypal integration for rental website. I have completed the integration for the payment. Now I am struck on one point: my concern is, I have completed the payment process using Authorization & Capture, now I have to write code to apply service tax on the payment. The service tax will go to the business owners account and rest payment will get returned to the end user's account. How can I implement this?
Reference URL that I have used::
https://developer.paypal.com/docs/api/quickstart/capture-payment/
Thank you
I see several possible designs:
Design #1: You authorize the payment and do not capture it, or do a partial capture for the service tax, holding it in a pending state (pendingreason=authorization) for up to 29 days, and capture any remaining desired amount (just service tax or full pending balance) within 29 days.
Design #2: You capture the full amount at checkout time, and do a partial refund (minus the service tax) within about 180 days, or whatever the refund term is on your PayPal account.
Design #3: You implement Order-Authorization-Capture, also known as AS2, which is even more complex but can give you a longer window than 29 days if PayPal enables this on your account. They must enable it, you don't get it by default.
A disadvantage of Design #1 is that authorizations do not hold funds on the customer's funding source for long -- so after some days, they will no longer be reserved, and a future capture on e.g. day 29 may fail.
A disadvantage of Design #2 is that you may incur some fee for doing that partial refund. I am not certain what the fees are for partial refund, but PayPal refunds are not as free as they used to be.
The disadvantages of Design #3 are that it is more complex to implement and you also need the help of someone experienced on the PayPal business support or account administration side to turn on features like a window longer than 29 days, or multiple captures per order.
So, those are some tradeoffs to consider.

Unless I'm missing something there doesn't seem to be a way to calculate shipping based on the customers address using the latest express checkout.
I'm aware that it can be done using the old legacy nvp instant api callback.
Just seems to be slightly ridiculous to not have this if this is the case.
It's one of those things to account for. Sales tax is another - also dependent on "where".
You'll get the address after a Paypal user "accepts" (aka "approves") your Paypal payment request. You can make adjustments not exceeding 115% of the original total of the payment originally requested.
Usually ok for sales taxes, but depending on your needs, may not work for shipping (e.g. can't do "flat" shipping rates, international shipping or if US, outside of continental US) so may need to account for it in your checkout flow e.g.
ask user for zip/country (data you can use for "estimate") prior to payment flows
perhaps restrict and/or make adjustments, if needed (along the 115% limit).
Hth...
I've made contact with Paypal who have advised they are working on a solution similar to the instant callback api that will work on the latest express UI.
For Express checkout, when I create a payment with intent=authorize.
after calculate shipping and tax, if the shipping + tax is greater than 15% of the original payment amount I got the error "AUTHORIZATION_AMOUNT_LIMIT_EXCEEDED".
It is very common that shipping + tax exceeds 15% of the original total especially for smaller and heavy items. What will be the way to go around it?
thanks,
Additional info:
when I look at classic PayPal express checkout's first step, It's not required to set any amount to log in to PayPal in order to retrieve shipping address, how do we do this with REST API?
https://developer.paypal.com/docs/classic/express-checkout/integration-guide/ECGettingStarted/#id084RM05055Z
That you may consider the PayPal InstantUpdate API, which allows you to update the tax & shipping calculation on the PayPal order review page (with AJAX).
Or alternatively, the common practice is to make the calculation before your payment request API call, on your website checkout flow (when customer fills in the shipping address and select shipping method), submit the precise amount to PayPal and then make the redirection.
You are not getting this error from DoEc, but later when you are later calling DoCapture on the authorization you generated in DoEC, right?
If so, then you are up against one of PayPal's protections for its consumers, which is that they don't allow merchants to get agreement for one price but then charge the buyer a much higher price. This is to avoid bad buyer experiences.
You basically have three options:
1) You can call PayPal CS and ask them to give you special permission to exceed the 115% limit. If you have enough history & volume with PayPal without generating disputes from users, then they may give you this permission. But this permission is usually only extended to large/trusted brands.
2) You can add an estimated tax, shipping and handling charge to the auth in Express Checkout. You would still tell the user that precise tax and shipping will be calculated when the item is shipped and their exact cost will vary. But your estimated charge should get you within 115% of the total. (Note: you usually should be able to get tax precisely at time of sale....)
3) You can decide on a fixed shipping and handling charge that allows you to cover your costs in aggregate and charge that in the EC flow. Yes, on one item that is larger/heavier than you expect you may loose $5, but on another that is smaller & lighter you will come out $5 ahead. This is what most people do.
I am using PayPal Payments Standard to upload contents from a custom shopping cart. i.e. The upload happens with a page redirect which posts the hidden vars to PayPal where the customer completes the transaction. When the transaction finishes, PayPal uses the "IPN" process to notify my the payment has been made.
In this case a reservation is made at the same time. The same as selling a limited stock item. As it wouldn't be good to have multiple PayPal transactions out there contending for the same slot, the reservation is made before the customer gets redirected to PayPal.
Once the Customer is at PayPal they might realize they don't have any money and close the window leading to an unpaid reservation that needs timed out and dropped.
Is there a guaranteed expiration time for the PayPal checkout page after which the reservation can be discarded without a risk of receiving a surprise payment for a deleted transaction? I realize IPN has it's own non-deterministic timing stuff, but without knowing there even is an expiration period, someone might sit on the website for a day and then pay.
Possibly too late to help you, but for the record: I asked PayPal tech support this question, as I couldn't find it in the docs either. They wrote:
Each transaction is associated with a token that expires after 3 hours
if the buyer didn't complete the checkout. This isn't usually
modifiable but can be extended by contacting a Business service
representative ( we don't recommend to extend it for security reasons
however. the token can't be less than 3H in any case)
So it's a MINIMUM of three hours.
I have a bit of experience setting up online payment systems that accept credit card numbers and then pass them over to a gateway for a one time payment.
However, I now need to setup a system that can handle automatic recurring billing - where a user provides their credit card number and is automatically billed on a monthly basis from that point forward.
I am wondering what the best way to approach something like this is? (I notice that Paypal Payflow Pro does have a recurring billing feature, but I am a bit unclear on how it works.)
Any advice on the best method / service / gateway for implementing recurring billing? If possible, I would greatly prefer to avoid keeping a local record of credit card numbers for repeat processing.
Thanks (in advance) for your help.
There's a midpoint between building your own recurring billing and Auth.net's ARB or PayPal's recurring billing (both of which have their disadvantages). There are a number of providers that handle all the details and complexities of recurring billing, and simply report the charges to your payment gateway for processing at the interval you determine.
The most critical piece to look at is which services to credit card tokenization and support credit card data portability - this will ensure that your customer data isn't locked in with a billing provider and that you can take it with you if you choose another provider in the future. This also means that these providers store the customer credit card data for you, so you can greatly reduce your PCI compliance.
Take a look at Recurly (Disclaimer: I manage their customer and technical support) and Braintree. Both services will handle your recurring billing, credit card tokenization, and support credit card data portability.
Recurring billing is easy to handle and offload to a third party if your recurring amount is constant (e.g. the amount a user pays never changes in amount or frequency). Services like Authorize.Net's Automated Recurring Billing (ARB) and Paypal Payflow Pro recurring billing allow you to have those companies handle the actual recurring payments which means you don't have to store credit card information on your servers or even do anything once the subscription is created through their APIs.
If your subscriptions will vary in terms of cost or frequency, you'll need to use a service like Authorize.Net's Customer Information Manager (CIM) to create payment profiles for your customers. Basically you're storing credit card information on Authorize.Net's servers and whenever you want to make a subscription payment you tell Authorize.Net to charge the amount due to that payment profile. The drawback to this is you essentially have to build your own subscription system.
You usually find the recurring billing features in middleware gateways like Payflow Pro. In that case, it is invoked by a variation of the API you use for card processing. You usually set up the time span between billings and they perform the billing. You usually then reconcile the billing with the report that your processor sends you each month. In some cases, the payment gateway will post a notification to you that the billing was performed. You still have to reconcile the payments with the processor report because sometimes the notifications fail.
Canceling the recurring billing is also another API call.
If your gateway doesn't have the recurring feature, you obviously have to set up the billing yourself. This of course leads to storing card info and so forth. In this case, you usually tell the processor that it is a recurring transaction (which the gateway will do for you) so you get a discount on the transaction fees.
First, let apend the statement above "...tell the processor that it is a recurring transaction ...so you get a discount on the transaction fees". The true cost of credit card processing is a percentage fee and a per item fee based on the type of card presented ( and some other factors I won't delve into here.) The point being, on a wholesale price plan, the price would be the same regardless of whether it was recurring or not because there are no special rates for 'recurring' in interchange. But I digress.
"Any advice on the best method / service / gateway for implementing recurring billing?"
Don't take on storing credit card data no matter what. You can't afford the liability.
The right choice depends on several factors.
As to credit card portability, has anyone gone to Wells Fargo/ First Data and gotten their data out? (Braintree ISO/MSP). I guarantee it won't be pretty no matter what so I would focus on the right long term solution, rather than the exit strategy, though it will certainly weigh in.
Here's questions that need to be answered:
How many transactions per month? For very low volume, maybe a few hundred, pick paypal pro. It's easy to get into/ out of.
Are people more likely to pay with consumer cards or business credit cards? Interchange optimization is important if business cards. (CenPOS automatically optimizes the transaction for lowest interchange qualification, paypal and authorize.net do not)
What methods does my client accept payments? self pay on internet only? Phone orders? Mobile payments (special events or retail)? Choose a gateway that fits all their needs.
Do you need to charge on specific days- ie the 1st and 15th? Or any time? If on specific days, how will you prorate? Check the answer against the gateway flexibility.
What happens when a card expires?
What happens when a transaction is declined?
Who will need to see the payment data for customer service? How will they access it?
Determine your needs, then figure out which ones meet them.
For the record, CenPOS is the most robust solution, but may require more steps to integrate since they are newer to ecommerce.
Disclaimer: I've been a business user of paypal and authorize.net for probably a decade and more recently CenPOS. I'm also an authorize.net reseller, and CenPOS direct agent.
Just a heads-up about Payflow Gateway's Recurring Billing:
Their Instant Payment Notifications (IPN) is a fantastic feature, but only applies to their legacy APIs. For the time being, THE ONLY WAY to be notified by PayPal of a successful (recurring) billing transaction, is by inquiry. You will need to maintain a schedule to inquire, and send an individual inquiry for each, scheduled recurring billing transaction, one at a time. PayPal will not notify you if, for example:
A transaction is approaching
A transaction has occurred
This transaction was successful
This transaction resulted in fault
A credit card is approaching expiration
A dispute occurred
... and so on.
In my opinion, this renders their service useless.
I am trying to use the Recurring payment API offered by PayPal.
I have a scenario which I am not able to address directly. It goes like this.
We have a website where we sell some services. Now the services are charged per user license. A user can buy/cancel user license in between. We want to offer the customer a recurring billing option. We have to notice here that the amount may vary each billing cycle based on the number of user licenses the customer uses during that cycle.
Is there any way I can achieve this using PayPal recurring Payment API's.
I realize this is a very old post, but it still shows up for Google searches, so I thought I'd add:
Paypal does allow you to do this now, using their new adaptive payments api.
Authorize.net also has a service that might work called Customer Information Manager.
The recurring payment option is a fixed amount that the customer pre-agrees to pay each month (or period). To do what you're trying to do, a customer would have to pre-agree to pay whatever amount you decide to charge at a later time. This means pre-authorizing an unknown payment amount, which will not be allowed by any payment service.
Your only options are:
Bill the variable amount each month (i.e. no subscription).
Set up a subscription where the monthly amount is the maximum that could potentially be billed, and then refund the difference each month.
Good luck with #2 - I would never agree to such a thing as a customer, personally.
What you're looking for is covered in the UK by the Direct Debit system, however given the potential for abuse it's very tightly controlled and there are a lot of restrictions and regulations governing it.
I'd strongly suggest you just set up a monthly invoicing system that just bills the client each month.
I don't know its meaning full or not as it is a very old post.
Instead of creating recurring profile on PayPal Server, You can store the customer's credit card on the PayPal using REST API: https://developer.paypal.com/docs/api/#vault then every month you can fetch it and charge it like recurring Payment Or When client is no longer with the services then just remove its card from PayPal.
I suppose Authorize.net SIM method also does the same.
Hope this make sense.
