Hi Donovan,
Thank your reaching out to our API support team.
From an API support perspective, your OAuth2 credentials should be specified in your .ini file (please refer
here) so the API can automatically refer to them when authenticating your API requests.
However, since it appears that your concern is more related to the PHP client library setup and how to access specific objects, then you may reach out directly to the PHP client library owners instead, via this
link, for further insight on the possibility of your requirement.
Best regards,
