i had open an ebay developer account, and created keys for sandbox mode . Now I tried several times to create a user token (i tried auth'n'auth and oauth modes), but I have all times a log in error message when i tried to login.
1) my exsisting ebay account (user: nunab-35 email email@example.com)
2) the ebay developer account credentials
3) another test account that i have created
The password recovery, moreover, send me to an error page. How i can create a user token correctly in order to test apis on a php application?
