I am trying to find documentations about Fields for Accounts, Contacts, and so on. I tried to locate it, but I can't find it anywhere. I know that you can use rest API to get that info, such as  getFields . But, isn't there supposed to be a documentation somewhere stating what it has? I don't feel like it make sense to ask developer to call an API to just view what are the exact field names are for a specific module

Thanks in advance!
