TPP (SystmOne)

Interface Mechanism 1 (IM1)

The NHS England national integration route by which approved third-party applications connect directly to GP clinical systems including TPP SystmOne. IM1 comprises the Transaction API (real-time read/write, e.g. appointment booking and structured record updates), the Bulk API (Strategic Reporting Extracts / aggregated data extraction), and the Patient Facing Services API. Onboarding is via the Digital Care Services IM1 Pairing Integration Process and a Supplier Conformance Assessment List (SCAL) approved by NHS England. Standards are published in the NHS England developer API catalogue, not on a TPP-hosted portal.
