“error”: 0,
“message”: “API configuration problem, consult your administrator”
help me

You should never have /web in your URL - this indicates a critical installation error. Only web should be served by your webserver, not everything underneath it.

I do not know if that will be the cause of the issue, but if you don’t fix that first you will have a terrible security risk.

This problem has been resolved by: web/api/authorize/index.php/access_token

I’m pleased you have it solved, but I will say again that running Xibo incorrectly is a security risk and you should please configure your webserver according to the installation instructions.
