From this link we have download api library files “https://github.com/mautic/api-library/tree/master/tests/Api” then again we copied the lead creation code from this link “https://developer.mautic.org/#leads” but no use getting fatal error with library files. If we am fixing one fatal error then facing another one. Can any one help with the below fatal error to move forward:

Fatal error: Interface ‘PsrLogLoggerAwareInterface’ not found in /home/grameen0/public_html/leadapi/lib/Api/Api.php on line 21
