How to process requests from PayPal (PayPal API)?

Question

PHP

I'm trying to figure out the PayPal API, do I understand correctly that if the PayPal servers return the status of the Pending transaction, then it is necessary to write all the transaction data to the database, after the transaction has the status Completed or Canceled, then delete the corresponding record from the database?

Answer 1

PayPal still has a certain period, the payer can dispute the transaction during this period. So it's better to store all transactions in the database
