is there a way to detect canceled transactions?
My API is working fine, but someone is cheating somehow, transaction pass verification and API get the info and credits are added to account, but after 30-45 sec transaction is canceled and I see only this message
"The payment was cancelled and the money was returned to the sender's account."
Thank you.
That's what IPN is for. If a payment status changes, you get a notice sent to you when it happens.

After one has created a monthly billing agreement with a customer; how do I verify that the customer has paid (and not cancelled the agreement) at the next bill statement?
Would I use GetRecurringPaymentsProfileDetails for this information? Basically, I want to automate cancellations/etc.
In your ipn end point a subscr_cancel txn_type is sent when this happens. Then you can update a record in your database to account for this.
Ipn messages when enabled send post requests for all kinds of actions such when a Payment is made or a subscription is cancelled. When you receive a message you need to validate the message, determine what message it is, and then perform an action in your application

I am applying PayPal Direct Payment on my website. My question is how much time is needed from when a Direct Payment is committed until I receive IPN message that the payment is Completed or for example Denied, Failed or something else?
Some important notes depending on how/why you are asking about "time":
IPN is an asynchronous message service, meaning that IPNs are not synchronized with actions on your website. Thus, listening for an IPN message does not increase the time required to complete a transaction on your website.
...
The IPN message service is not a real-time service. As a result, your listener may not receive an IPN message for many seconds after an event occurs. As a result, your checkout flow should not depend upon receiving an IPN message to complete. If it does, your checkout flow will be slow during periods of heavy system load and complicated, since it must handle retries.
REF: Introducing IPN
Hth...
That should be instantaneous and will certainly be no more than a couple of seconds. As soon as PayPal receives a Payment to your account it will send this Instant Payment Notification. I think the name says it all.

I am currently working on a project using PayPal. When I made a transaction, the payment status in the IPN received was 'Pending' and reason was Payment review. I found out that it will take 24 hours for the review process. So I want know if I will get an IPN when the review process is over?
You should get an IPN notification when the transaction changes status. For example, PayPal sends you an IPN notifying you of a pending payment. PayPal later sends you a second IPN telling you that the payment has completed.
Because of security reasons you may get the first IPN with payment status pending But when the payment review is over You will get another IPN with payment status as completed.You can can transfer your stuffs then.The payment review will take maximum 24 hours.
I am working on the paypal recurring payment and I have set the MaxFailedPayments as 3. I want to send email to user when the this maximum failed payment has reahced 3. So from which status field in the IPN message ,we can understand MaxFailedPayments has reached ?
Thanks in advance

There is a "txn_type" value that tells you when a Recurring Profile reaches it maximum failed payment attempt limit - txn_type=recurring_payment_suspended_due_to_max_failed_payment
You can use that to trigger your notice to buyers.
You should receive an IPN post when the payment fails - txn_type=recurring_payment_failed
Trigger a notice to send out after two failed payment IPN posts arrive instead of waiting for the third failure and the Profile going into a suspended status.
I have done some scouring but cannot find a definitive answer for this!
I get "VERIFIED" and "Pending" so i can put my orders from "placed" to "in-progress" but need the complete / failed so i can then transfer to "paid" and "cancelled".
Anyone have anything definitive on this, or is it a waiting game until test payments are complete (not using sandbox).
If the payment has a “Pending” status, you receive another IPN when the payment clears, fails, or is denied.
Also, here are some good things to check once you receive Payment_staus=completed
Check that the "txn_id" is not a duplicate to prevent a fraudster
from using reusing an old, completed transaction
Validate that the "receiver_email" is an email address registered in
your PayPal account, to prevent the payment from being sent to a
fraudster's account
Check other transaction details such as the item number and price to
confirm that the price has not been changed
You get another IPN (not a 'resend'), same txn_id, with payment_status='Completed'.
