Transaction Layer Integration

    A zero-retention transactional bridge between your data and your downstream systems

    Brandywine's Transaction Layer Integration service acts as the transactional connection point between client data and downstream systems — without maintaining or storing any client data. Every payload is processed in volatile runtime memory and controlled transient buffers, then forwarded to the destination system or vendor and immediately discarded. This pattern is purpose-built for clients who need real-time data transformation across X12, EDI, FHIR, HL7, JSON, and proprietary formats but cannot — or will not — allow a third party to retain their data. BCP only maintains summary-level runtime logs (counts, latencies, status codes, correlation IDs) for auditing and operational visibility; no PHI, PII, or client artifacts ever land at rest in BCP-controlled infrastructure.

    What We Do

    Service overview and the core capabilities BCP brings to every transaction layer integration engagement.

    Zero-persistence message processing in volatile runtime memory
    Controlled transient buffers with deterministic TTLs and secure wipe
    X12 EDI translation (837, 835, 270/271, 276/277, 834, 820)
    HL7 v2.x ↔ FHIR R4 transformation and routing
    JSON / XML / flat-file / custom format normalization
    Real-time and near-real-time message routing to downstream vendors
    In-flight enrichment, validation, and schema conformance
    Field-level redaction, masking, and data minimization
    mTLS, OAuth2, SFTP, AS2, and VPN transport security
    Summary-only runtime logging for audit and SLA reporting
    Replay-from-source patterns (no payload retention required)
    Dead-letter handling without payload persistence

    Key Benefits

    Zero Data at Rest

    Payloads exist only in volatile runtime memory and controlled transient buffers — never written to disk, database, or backup inside BCP-controlled infrastructure.

    Reduced Compliance Surface

    Removing storage from the integration layer eliminates entire categories of HIPAA, GDPR, and contractual risk for your organization and ours.

    Real-Time Throughput

    Stateless, horizontally scalable runtime delivers sub-second translation and routing at millions of transactions per day.

    Real-time transactional integration layer routing healthcare data with zero retention
    Pass-through, not pass-store

    Translate, validate, and route every payload — without ever persisting client data.

    Who We Serve

    The audiences this service is built for, with the specifics that matter to each.

    • Benefits eligibility and verification routing
    • Federal reporting submission with audit-only logging
    • Inter-agency exchange with FedRAMP-aligned controls

    Typical Triggers

    If any of these sound familiar, you're in the window where this service delivers the most value.

    Legal or security policy forbids storing PHI/PII

    Counsel, CISO, or regulator has ruled out third-party data retention in the integration layer.

    Trading partner contract bars data retention

    Hospital, payer, or sponsor BAA / DPA prohibits the integrator from persisting payloads.

    HL7 ↔ FHIR or EDI ↔ API bridge needed

    Modern consumers need FHIR or REST while sources still emit HL7 v2 or X12.

    Existing integration engine retains too much

    Mirth, Rhapsody, BizTalk, or MuleSoft databases have become a compliance liability.

    Auditor demands data minimization

    HIPAA, HITRUST, SOC 2, or GDPR finding requires removing payloads from the transit layer.

    Multi-vendor brokering with strict isolation

    Need to route between many partners without becoming the de facto system of record.

    SOC 2 Type II

    BCP operations are SOC 2 audited; transactional layer change management, access reviews, and incident response covered under report (available under NDA).

    GDPR (purpose limitation & storage limitation)

    21st Century Cures Act / ONC interoperability

    FHIR R4 and USCDI-compliant translation supports Patient Access, Provider Directory, and Bulk Data export patterns.

    NIST 800-66 / 800-53

    Regional health plan, ~600K members

    Zero-retention EDI gateway for a regional health plan

    Challenge

    Compliance and legal banned the prior clearinghouse from storing 837 and 835 transactions on behalf of the plan; existing integration engine's database had become an audit liability.

    BCP Solution

    • Replaced prior pipeline with a stateless Azure Functions + Service Bus gateway
    • All 837/835/270/271/834 transactions translated and routed in volatile memory
    • Transient Service Bus topics with 60-second TTL for in-flight reliability only
    • Azure Monitor configured with payload scrubbing and DLP deny-lists
    • Replay handled by re-submitting from the plan's authoritative core admin system

    HL7 → FHIR pass-through broker for a digital health vendor

    Challenge

    Enterprise hospital customers required the vendor to broker HL7 v2 ADT/ORU feeds into a downstream analytics partner without the vendor ever storing the messages — a hard contractual constraint blocking new logo signings.

    BCP Solution

    • Built a multi-tenant, stateless HL7 → FHIR R4 conversion gateway on Azure Container Apps
    • Per-tenant cryptographic isolation with customer-managed keys in Key Vault
    • Event Hubs configured with minimum-viable retention for in-flight replay only

    How much PHI is your integration layer still holding?

    Five quick questions on PHI retention risk and zero-retention design. Answers stay in your browser — nothing is transmitted, stored, or tracked by us. Fittingly, this poll retains no data either.

    0 of 5 answered0%
    1. 01Where does most of your PHI risk actually sit today?

      Pick the surface that keeps your security team up at night.

    2. 02How long does PHI sit in your integration layer before it is purged?

      Count staging, replay buffers, and archived payloads.

    3. 03What is driving the conversation internally right now?

      The trigger usually shapes the timeline.

    4. 04Could you produce a complete PHI data-flow map this week?

      Every hop, every copy, every retention rule.

    5. 05How appealing is a zero-retention transaction layer for your organization?

      BCP acts as the transactional connection point — no PHI left behind.
