Hi, i'm new with paypal, php and javascript, the fact is that i have to do this job. I'm trying to integrate express checkout in a web site, and i'm almost done, i have success already, but nothing happens at the end of the transaction and i don't know why, i hope you can help me. What does this line return fetch('/paypal-transaction-complete', do? and how can i change it in order to catch the results of the transaction?, Do i need to have a file named 'paypal-transaction-complete' to handle the answer of paypal? I'm sorry if i'm a complete newbie, i just want to learn about it and to get success doing this job Thanks in advance.
