PayPal IPN sending multiple messages

Time:10-05

I am working in PayPal sandbox. I have configured IPN to post to my server url, and I am surely running through all the cycle of IPN (it sends me the message, I send 200, then I send message, then I am getting VERIFIED from PayPal). But a day after, I just got another message from PayPal. Why it happens? I know PayPal will continiously send me messages if I dont respond, but I respond to everything. How can that be?

My code for verification I have taken from this article:

The second message:

CodePudding user response:

message 1:

payment_status=Pending&pending_reason=paymentreview

message 2:

payment_status=Completed

These are separate events for different stages of the payment, hence separate IPN messages.
