TPP (The Phoenix Partnership) is a UK healthcare software company founded in 1997 and headquartered in Leeds, England. Its flagship clinical system, SystmOne, is one of the two dominant GP electronic health record platforms in England (alongside EMIS Web) and holds more than 61 million patient records shared across the NHS, serving over 300,000 users and 7,800+ organisations spanning general practice, hospitals, urgent care, mental health, community, and social care. TPP does not operate a public self-serve developer portal; integration is a gated, partner-conformance process. Third parties integrate with SystmOne through NHS England's Interface Mechanism 1 (IM1 Transaction, Bulk, and Patient Facing Services APIs) and the national GP Connect FHIR programme, both governed by the Digital Care Services (DCS) framework and a Supplier Conformance Assessment List (SCAL) approved by NHS England. TPP additionally publishes its own downloadable interface specifications - the SystmOne Client Integration API (XML over a TCP socket), a Patient Facing Services (PFS) API, a Generic HTML API, and a Telephony API - and a formal Integration Request process. Home market is the United Kingdom, exclusively within the NHS.
