The Postings API provides a number of Posting Types, such as Authorisation and Settlements. These types of postings are used to model complex financial processes such as

Card Payments, and the types of postings allow you to record a statement of intent with your postings



The key benefit of these Posting Types is that we are able to enforce logical financial processes such as Authorisations & subsequent settlements of funds during a typical

Card Transaction, where we mandate an authorisation must occur before a settlement.
