I am working on implementing Authorize.Net's Automated Recurring Billing API in Laravel Framework.
The scenario is I have a site, users sign up for our services and we charge them on monthly basis, and for that we have implemented automated recurring billing.
But I am unable to get the transaction id of successfully placed transactions.
ARB does not return a transaction ID when a payment is processed. It only establishes the recurring subscription. If you want transaction IDs of every successful subscription payment you will need to use one of two options available to you.
Webhooks
You can set up a webhook using the Webhooks API to be notified whenever a successful payment is made for a subscription. Although very little information is sent over with a webhook as it is best paired with the Transaction Details API, the transaction ID is one of the pieces of information sent with a webhook notification.
Silent Post
Silent Post is very similar to Paypal's IPN. Whenever a transaction is made Authorize.Net will send transaction details to a URL you specify which includes the transaction ID. Handling a Silent Post notification is easy as it looks exactly like a form submission.
Silent Post has been deprecated and will be going away so it is not recommended that you use this any more.
Disclosure: I wrote the articles about Webhooks and Silent Post.

I am trying to integrate the PayPal REST API into my Symfony 2 web app but I find hard to understand how exactly the complete workflow looks like:
The PayPal docs describe the following steps to accept a payment. One can use the PayPal Playground to simulate these steps:
Get an access token
Create a Payment object by querying the API
Redirect the user to the approval url received in the Payment response
After the user approved the payment on the PayPal page, he is redirected back to my page, using the success-link defined in the Payment object. Use the received information to execute the payment.
Payment is completed with status approved
From the docs: Once a payment is complete, it is referred to as a
sale. You can then look up the sale and refund it.
So far so good. BUT: Where are Webhooks used/fired in this workflow? I have defined a wildcard Webhook (accepting all possible events) in the PayPal Developer Dashboard.
My observation is, that my system receives the Webhook event 1-2 Minutes (!) after the user was redirected back to the success-link and after the payment was executed (Step 4).
Beside this long delay between executing the payment and receiving the Webhook, this workflow means, that I only receive the Webhook AFTER handling the success-link. This means, handling the success-link is absolutly necessary for the payment to be completed. Is this correct?
Do I need to use Webhooks?
I already asked this question a few days before and the answer by nifr is quite reasonable: One cannot trust the user to follow any redirect URL but should only rely on the Webhook events.
However this collides with the observations I described before, since I will never receive the Webhook without handling the redirect URL...
So, handling the PAYMENT.SALE.COMPLETED webhook event does not make a lot of sense, since this should already be done in when handling the redirect URL. Correct?
However, to handle updates on pending payments, handle refunds or reversed payments, etc. are only possible by listening on those events.
So the answer is: Only use Webhooks to get updates on payments made before. Correct?
So, the main questions are:
The 5-step process to accept payments does not say anything about using Webhooks. This does not seem to make a lot of sense, because without Webhooks one would miss update events, etc.? So, is it really possible to implement the complete payment workflow without Webhooks?
If yes, how are updates (refunds, pending, etc) handled in this case?
If no, what is the right strategy/time to fulfill the order since it take quite a long time to completly receive and handle the webhook?
i am still a newbie in PayPal world, but few days ago i integrated PayPal Plus REST API in an online Shop, and from my understanding i can tell that the workflow looks like:
create a Payment
redirect to PayPal
Payer could pay using PayPal account OR (using Bank Direct debit or Credit Card Payment without PayPal Account)
After completing the process on PayPal side, PayPal redirect the user back to your success URL.
till now the user is still not charged(you got no money). At the moment where you (in your success URL) do $payment->execute($paymentExecution,$api); , you ask Paypal to charge the amount from user. BUT also after this, you got no Money. Paypal have first to process the charging and notify you later via WebhookEvents.
the Webhook Notification (with that nasty delay) is especially important when the user pays per direct debit or Credit Card etc. Processing such Payments takes few seconds/minutes.
the redirectUrl ist absolutly necessary for charging/executing the Payment.
here on execution succeed, just to tell the user, that he finished his Job, and you can here save/capture the PaymentID/Transaction id for later usage/update via WebhookEvent Listener.
so i would recommend you to update your Database(Payment completed) only after receiving notofications via WebhookEvent Listener and not in the success RedirectUrl.
Does anyone know is there any way to check status of recurring (subscription) payment at PayPal.
I just want to submit transaction ID and to see is payment canceled (suspended) or it is still active.
If you're using the Recurring Payments API you can use GetRecurringPaymentsProfileDetails to obtain details including the current status of the profile.
If you're working with Standard Subscriptions, though, then there is no API to obtain the details, unfortunately.
In either case, I'd recommend looking into Instant Payment Notification (IPN). Using it you could automate the process of sending email notifications, updating your own database, etc. when new profiles are created, suspended, re-activated, etc.
I am having a very hard time figuring out whether it is even possible, but here is the task I want to do. Whenever an invoice that is created by my merchant account, I want PayPal to send a webhook to my webserver notifying that the invoice has been paid for. I can find full documentation on how to do that for simple payments, but there is literally nothing documented on how to do that with an invoice.
Instant Payment Notification (IPN) can be used for this.
When a PayPal invoice is paid the PayPal server will POST transaction data including the PayPal invoice ID and any custom invoice ID you supply with the original invoice. That way you can automate procedures based on the transaction data.
IPN works with all payments, refunds, disputes, etc. on your account. It's a very useful tool.
How can I capture paypal IPN and Authorize.net "Silent Post" messages?
I'm fine with how to make payments with Omnipay but I could not yet figure out how to listen to the callbacks from these APIs to detect changes for my payments.
For example Authorize.net processes it's credit card payments one time per day (late night for me) and then sends out it's messages via their so called "silent post" (its just a http POST) notifications. So the API call might be immediately "accepted" but I won't know for sure if everything is OK with the payment until I receive the callback.
So how do I set up Omnipay to listen to APIs that do these kind of delayed callbacks?
I'm aware that I'll need a callback URL like /payments/callback/ to load the right gateway to do something with the callback. But I could not yet figure out what method(s) from Omnipay I have to use for it.
Omnipay doesn't support notifications for existing payments. It automatically handles the first notification which is made directly after a payment, but doesn't yet have methods to handle notifications if you change the status of a payment (for example by refunding it from PayPal's control panel, it will not update in your database automatically).
Note this isn't needed for the initial payment. Especially with PayPal Express the payment is not confirmed until the customer returns to your site, so there is no chance of them closing the browser window and the payment being lost.
If you want to set up a notification endpoint and listen for events which happen after the payment is processed, you will need to add a new request type to Omnipay.
I'm just starting out with Paypal, so this is a newbie question.
I've been going through the instructions for setting up Paypal subscription service, but I think I'm looking at the wrong thing.
What I want to acheive is to get back some kind of response from Paypal so that I can update the database on my web site to mark a registered user as having paid. Basically I have a flag in the database that says if the user is subscribed or not. I want to ensure that the user is marked as paid so long as their Paypal subscription is maintained.
While the instructions linked above do say how to set up a button to receive a payment, there's nothing there about getting any data back from Paypal.
I know there are terms like IPN and sandbox that are related to what I'm trying to do, but I can't find clear instructions for how to get started on this process. I'm just circling around and not getting anywhere.
Where do I start on setting this up? Where is there a clear beginner's tutorial?
Also, I'm using PHP/Javascript/MySQL on my website.
PayPal's IPN service is what you want to use. I've used it myself to do just what you're looking to do.
Instant Payment Notification (IPN) is PayPal's message service that
sends a notification when a transaction is affected. Once IPN is
integrated, sellers can automate their back office so they don’t have
to wait for payments to come in to trigger order fulfillment. IPN can
send notifications for these transactions:
Instant payments, including Express Checkout and direct credit card payments
eCheck payments and pending, completed, or denied status payments
Pending payments
Recurring payments and subscriptions
Authorizations
Disputes, chargebacks, reversals, and refunds
You can also view notifications on PayPal’s IPN History page and
resend them if you need to. As PayPal’s interface for handling
purchase confirmation and server-to-server communications, IPN can
also be used to manage and customize a variety of APIs and
communications, including:
Customize your website's response to customer purchases in seconds
Track customers via IPN "pass-through" variables
Notify sellers who deal mostly in software downloads and other digital, online goods
Track affiliate sales and commissions
Store transaction information in your own database

I'm not sure if its the same thing, but I just setup my friends website with Express Checkout, and I wanted to add all paid orders to an orders table in my database.
After I call SetExpressCheckout, and the user is returned to my site after going through the purchase flow on Paypal's side,
I used the information from GetExpressCheckoutDetails.
Then, if DoExpressCheckoutPayment
is successful (also called from the "callback" page) I then do the appropriate work in my database as far as logging the order details. For you in this case, it could be updating a record for the user in the database.
Hope that helps a little.
