how can I get all records from a object/table with rest api from netsuite?

https://docs.oracle.com/cloud/latest/netsuitecs_gs/NSAPI/NSAPI.pdf I guess this is where you will want to start.

I am trying to call netsuite rest api in postman like https://xxx.suitetalk.api.netsuite.com/services/rest/record/v1/customer can you help me to understand what/how the security things should be passed. I have already add role and authorization for api access.
