Sharing this as I ve recently encountered issues similar to this thread   For a long time  my script worked well  basic payment form  and returned the POST variables to my success php page and the IPN data as POST variables also   However  lately  I noticed the return page  success php  was no longer receiving any POST vars   I tested in Sandbox and live and I m pretty sure PayPal have changed something    The notify url still receives the correct IPN data allowing me to update DB  but I ve not been able to display a success message on my return URL  success php  page     Despite trying many combinations to switch options on and off in PayPal website payment preferences and IPN  I ve had to make some changes to my script to ensure I can still process a message   I ve accomplished this by turning on PDT and Auto Return  after following this excellent guide   Now it all works fine  but the only issue is the return URL contains all of the PDT variables which is ugly    You may also find this helpful

on the checkout page  look for the  cancel return  hidden form element    set the value of the cancel return form element to the URL you wish to return to

one way i have found   try to insert this field into your generated form code    lt input type  hidden  name  rm  value  2  gt    rm means return method    2 means  post   Than after user purchases and returns to your site url  then that url gets the POST parameters as well   p s  if using php  try to insert var dump   POST   in your return url script  then make a test purchase and when you return back to your site you will see what variables are got on your url

I think that the idea of setting the Auto Return values as described above by Kevin is a bit strange   Say  for example  that you have a number of websites that use the same PayPal account to handle your payments  or say that you have a number of sections in one website that perform different purchasing tasks  and require different return-addresses when the payment is completed  If I put a button on my page as described above in the  Sample form using PHP for direct payments  section  you can see that there is a line there   input type  hidden  name  return  value  https   www yoursite com checkout complete php    where you set the individual return value  Why does it have to be set generally  in the profile section as well      Also  because you can only set one value in the Profile Section  it means  AFAIK  that you cannot use the Auto Return on a site with multiple actions   Comments please

You have to enable auto return in your PayPal account  otherwise it will ignore the return field   From the documentation  updated to reflect new layout Jan 2019       Auto Return is turned off by default    To turn on Auto Return          Log in to your PayPal account at https   www paypal com or https   www sandbox paypal com   The My Account Overview page appears    Click the gear icon top right     The Profile Summary page appears     Click the My Selling Preferences link in the left column    Under the Selling Online section  click the Update link in the row for Website Preferences    The Website Payment Preferences page appears   Under Auto Return for Website Payments  click the On radio button to enable Auto    Return     In the Return URL field  enter the URL to which you want your payers redirected after    they complete their payments     NOTE  PayPal checks the Return URL that you enter  If the URL is not properly formatted    or cannot be validated  PayPal will not activate Auto Return     Scroll to the bottom of the page  and click the Save button       IPN is for instant payment notification   It will give you more reliable useful information than what you ll get from auto-return   Documentation for IPN is here  https   www x com sites default files ipnguide pdf  Online Documentation for IPN  https   developer paypal com docs classic ipn gs IPN   The general procedure is that you pass a notify url parameter with the request  and set up a page which handles and validates IPN notifications  and PayPal will send requests to that page to notify you when payments refunds etc  go through   That IPN handler page would then be the correct place to update the database to mark orders as having been paid
