Your problem
I installed api-tester from github (https://github.com/mautic/api-library/blob/6a821deadd94c5917f2781fa170467079b050d6f/apitester/index.php) doing download and unzip method (put all files from repo into /lib folder. When i try to access the tester by https://mautic.mydomain.com/api/apitester/ i get this JSON error response in my browser:
{“errors”:[{“message”:“API authorization denied.”,“code”:401,“type”:“access_denied”}]}
So i guess, even for the tester i need to provide some credentials. I turned basic auth on (for testing) but still no login dialog appears. Maybe there are some URL-params needed to use this?
These errors are showing in the log:
