SETTINGS –> Setup –> Settings –> API

Allow API - should we enable API?
Allow GET API - should we allow GET method to be used for API? Good for testing - but do not use in production! It is unsafe.
API Secret Key - key to generate Hash
XML API Extension - send XML output with <HTML> tag - this is used for broken .Net support, keep it unchecked if everything works for you
Allow API Login Redirect - if login is successful the customer will be redirected to MOR billing Main site.
