I am getting error 400 Bad Request from POST https://api.ebay.com/identity/v1/oauth2/token
Hello,
When I try to retrieve my access token from my Java code, I receive a 400 error.
I have two other accounts for which I do not encounter this issue, so the Java code appears to be correct since it works with those two accounts. In addition, it used to work with this account as well, but it suddenly stopped working.
However, for the third account, it no longer works, even though the following information has been verified and is correct:
Client ID
Client Secret
Refresh Token
Redirect URI
Do you have any idea what could be causing this issue?
Thank you in advance for your help.
