Money, dates and ids

Integer pence, UK dates as YYYY-MM-DD, UTC timestamps and numeric ids. The rules every field follows.

Field ends in Type Example Notes
_pence integer 75000 £750.00. Never send pounds as a decimal.
_on date 2026-11-01 A calendar date in the UK. No time, no zone.
_at timestamp 2026-10-12T17:53:00Z ISO 8601 in UTC.
_id / id integer 41 Abide.Rent’s own id. Ids are only meaningful inside the workspace that returned them.

Rent is per the tenancy’s rent_frequency (usually monthly). Where an input also accepts rent in pounds, prefer rent_pence.

Property identifiers you can also send: uprn, property_registration_number (PRN) and landlord_registration_number (LRN). A PRN is unique: sending one that another property holds answers DUPLICATE_PRN.
