Hi, @31ycb (31ycb)​ 

Thank you for posting on our Community page!

As the article you mentioned states, the prerequisites are to create a custom user with the following permissions:

“ A custom user profile in Salesforce (needed for both REST and SOAP integrations). Once you have created a custom profile in the Salesforce portal, edit the profile's Administrative Permissions to enable the following:

• API Enabled.
  • Manage Users: Enabling this option automatically enables the following: Assign Permission Sets, Manage Internal UsersManage IP Addresses, Manage Login Access Policies, Manage Password Policies, Manage Profiles and Permission Sets, Manage Roles, Manage Sharing, Reset User Passwords and Unlock Users, View All Users, View Roles an, Hierarchy, View Setup and Configuration.
• See also Salesforce Create or Clone Profiles documentation.
• Assign the permissions directly to the profile. Don't add the permissions through permission sets.”

Please check this table to see what Admin types have the permissions you need:
