Note

: Pre_posting_code is the hot path hook. It typically has strict performance SLAs as it blocks the committing of a posting to the ledger on a

hot path that could be a card payment or bank transfer. Payment providers generally expect a Payment to be accepted or rejecte d within a

few seconds. Therefore, the pre_posting_code hook is limited in what data it can fetch and what Hook Directives it has access to. All other

hooks are non hot paths. This means they have access to all directives and data.
