If you made your purchase of a course and/or exam before June 21, 2020, you may find your receipt by logging into identity.linuxfoundation.org and going to the Orders tab.
If you purchased after June 21, 2020, please login to trainingportal.linuxfoundation.org and click on Purchase History in the banner at top. If you created a new LF Login account to make the purchase, please be aware that you have to validate the email address on that LF Login account before you can load the Purchase History section. If you have not yet completed that step on your account, logout of the portal and log back in... you should be prompted to validate your email as the first step. Once you have validated your email and then logged back in, go to the Purchase History section. (It may take up to 15 minutes for the page to load, so please click on Purchase History and then check the page again after 15 minutes if needed.)
