Introduction
LogiCoy eRx is a Surescripts-certified and ONC-certified electronic prescribing platform that provides a comprehensive REST API suite enabling healthcare technology companies to integrate complete e-prescribing workflows—including new prescriptions, cancellations, renewals, medication history, EPCS, prior authorization, and real-time prescription benefit—directly into their EHR, telehealth, and clinical applications.
Adding electronic prescribing to an EHR, EMR, telehealth platform, or healthcare application involves much more than simply sending a prescription to a pharmacy. A production-ready e-prescribing solution needs to support the complete prescription lifecycle—from identifying the patient, clinician, medication, and pharmacy to transmitting prescriptions, handling cancellations and renewals, receiving pharmacy requests, retrieving medication history, checking benefits, and supporting controlled-substance prescribing.
LogiCoy eRx provides a comprehensive e-prescribing API suite designed to give healthcare technology companies the building blocks required to integrate electronic prescribing directly into their applications. The platform is Surescripts-certified and ONC-certified, providing an established foundation for integrating electronic prescribing capabilities into healthcare products.
Who Can Use the LogiCoy e-Prescribing API Platform?
The APIs are designed primarily for organizations building or enhancing healthcare software, including:
- EHR and EMR vendors
- Telehealth platforms
- Digital health companies
- Healthcare technology startups
- Clinical workflow applications
- Practice management platforms
- Healthcare service platforms
- Other applications that need integrated electronic prescribing
Instead of building prescription connectivity, pharmacy directories, medication workflows, and prescription lifecycle management independently, developers can integrate these capabilities through the LogiCoy eRx API platform.

This breadth allows an application to integrate e-prescribing as an end-to-end workflow rather than as a single prescription submission function.
Patient APIs
A reliable electronic prescribing workflow starts with accurate patient information. The Patient APIs allow healthcare applications to create, maintain, retrieve, and search patient records within the LogiCoy eRx environment.
Patient API Capabilities
- Patient registration
- Patient demographic updates
- Patient profile retrieval
- Patient existence and status verification
- Patient listing by service location
- Patient search
- Synchronization of patient information from an EHR or EMR
The APIs are designed to support the patient context required by subsequent prescription workflows. Patient information can include demographic, contact, and clinical attributes used during prescribing and validation.
Clinician and Prescriber APIs
Electronic prescribing requires more than a provider’s name. Prescribing applications need to associate clinicians with their professional identifiers, practices, service locations, and authorized prescribing capabilities.
Clinician API Capabilities
- Clinician registration
- Clinician profile management
- NPI and DEA information
- Practice association
- Service-location association
- Prescribing permissions
- EPCS and non-EPCS configuration
- Clinician lookup
- Service-level authorization
The platform supports prescribing service levels including new prescriptions, cancellation, change, refill, fill-related workflows, controlled substances, electronic prior authorization, and pharmacy-initiated prescription requests. This allows an EHR or healthcare application to maintain the prescribing context needed for different clinical workflows.
Practice and Service Location APIs
Healthcare applications often operate across multiple practices, clinics, and physical locations. LogiCoy eRx provides APIs for managing this organizational hierarchy.
Practice API Capabilities
- Create a practice
- Update practice information
- Retrieve practice information
- Manage practice configuration
Service Location API Capabilities
- Create service locations
- Update service locations
- Retrieve service locations
- List service locations
- Associate clinicians with locations
- Retrieve clinicians associated with a location
Service locations are important because prescribing configuration, routing, authorization, and compliance can depend on the location from which a clinician is prescribing.
Pharmacy Lookup APIs
Selecting the correct pharmacy is an essential part of an electronic prescribing workflow. The Pharmacy APIs provide access to pharmacy directory information and allow applications to search for pharmacies based on criteria such as:
- Pharmacy organization
- Location
- City and state
- Postal code
- NCPDP identifier
- Pharmacy specialty
- Supported prescription transaction types
Applications can use the pharmacy directory to identify pharmacies capable of supporting particular prescription workflows, including new prescriptions, refills, changes, cancellations, and controlled substances. The API design supports structured search rather than requiring an application to maintain its own pharmacy directory.
Drug and Medication Search APIs
Medication selection is another fundamental component of e-prescribing. The Drug Search APIs allow applications to search for medications and retrieve medication information using approaches such as:
- Product name
- Strength
- Unit
- NDC
- Medication identifiers
Applications can use these APIs while composing a prescription to identify the appropriate drug product, strength, dosage form, and package information. NDC-based lookup is particularly useful when medication information originates from another clinical system.
e-Prescribing API for Prescription Lifecycle
The Prescription APIs form the core of the LogiCoy eRx platform. They support the prescription lifecycle from initial composition through transmission and subsequent pharmacy-related workflows. The prescription service supports draft prescription management, new prescription transmission, cancellation, fill status, transaction status, and prescription history.
Draft Prescription Management
Applications can create prescriptions as drafts before transmitting them to a pharmacy. The draft workflow includes capabilities to:
- Add draft medications
- Update draft medications
- Remove draft medications
- List draft prescriptions
A typical draft prescription workflow:
Draft medications can be modified before transmission. Once the prescription has been transmitted, subsequent changes follow the appropriate prescription change or cancellation workflow.
New Prescription Transmission
The RxNew APIs enable healthcare applications to electronically transmit new prescriptions to pharmacies. The typical workflow:
The platform provides an API for transmitting the new prescription and additional APIs for checking verification or transaction status where applicable. The API design allows the calling application to provide the clinical and prescription context required to transmit the medication electronically without requiring the application to directly implement the underlying pharmacy-network messaging.
Prescription Cancellation
The RxCancel APIs support the electronic cancellation workflow. Applications can:
- Submit a cancellation request
- Track cancellation processing
- Retrieve the resulting cancellation status
The cancellation workflow validates that the prescription was previously transmitted and then sends the cancellation request through the connected pharmacy network. Because cancellation processing can involve an asynchronous pharmacy response, the API suite separates submission from status retrieval.
Pharmacy-Initiated Prescription Changes
Pharmacies may need to contact a prescriber regarding a prescription—for example, to request a dosage modification, quantity change, therapeutic alternative, or formulary substitution. The RxChange APIs support this bidirectional workflow. Applications can:
- Receive notification of a pharmacy-initiated change request
- Retrieve the complete request details
- Present the request to the prescriber
- Submit a structured response
Supported responses include approval, approval with changes, denial, and validation. This makes it possible for an EHR or telehealth application to incorporate pharmacy-initiated prescription changes directly into its clinical workflow.
Prescription Renewal Workflows
The RxRenewal APIs support pharmacy-initiated renewal requests when a patient’s existing prescription requires authorization from the prescriber. The workflow includes:
The renewal APIs also support appropriate audit and EPCS-related validation.
Prescription Refill and Fill Status
Prescription fulfilment does not end when a prescription is transmitted. LogiCoy eRx provides APIs supporting refill and dispensing-related workflows, including fill status and fill indicator updates. These capabilities allow an application to:
- Track prescription fill status
- Retrieve pharmacy fill information
- Update fill indicators
- Incorporate dispensing status into clinical workflows
This can be particularly useful for EHRs that want to provide clinicians with visibility into what happened after a prescription was transmitted.
Prescription and Medication History API
Medication history is a critical clinical capability for medication reconciliation, clinical decision-making, and patient safety. LogiCoy eRx provides RxHistory APIs for requesting and retrieving prescription medication history from pharmacy networks.
The workflow is designed around asynchronous processing:
The APIs support patient medication history requests, date-range selection, consent information, transaction tracking, and retrieval of medication fill records. The resulting history can contain medication and dispensing information such as medication identifiers, quantities, days supply, fill dates, substitutions, and refill information.
Electronic Prior Authorization APIs
Prior authorization can introduce significant friction into the prescribing workflow. LogiCoy eRx includes APIs supporting electronic prior authorization (ePA) workflows.
The platform’s clinician configuration includes support for the ePA service level, while the broader advanced API capabilities include prior-authorization-related workflows and benefit coordination. This allows healthcare applications to incorporate prior authorization workflows alongside prescribing rather than treating them as a completely separate process.
Patient Eligibility, Formulary, and Benefit APIs
Patient Eligibility and Coverage
Before applying formulary or prescription benefit information, an application may need to determine the patient’s active pharmacy coverage. The Eligibility and Coverage API retrieves patient-specific eligibility and health-plan coverage information. This information can then be used as part of downstream formulary, benefit coordination, and real-time prescription benefit workflows.
Formulary Checks
Formulary information helps clinicians understand whether a medication is covered by a patient’s health plan and whether restrictions or alternatives may apply. The Formulary API provides on-demand formulary checking for a medication using patient eligibility and benefit information. Applications can use formulary information to support:
- Coverage checks
- Formulary status
- Benefit-related decision support
- Alternative medication selection
- Prior authorization workflows
Real-Time Prescription Benefit (RTPB)
A modern e-prescribing workflow increasingly needs to answer a question before the prescription is sent: What will this medication cost this patient, and is it covered?
LogiCoy eRx supports Real-Time Prescription Benefit (RTPB) workflows. The RTPB APIs can be used to obtain patient-specific prescription benefit information and apply the resulting benefit information to the medication workflow. The RTPB workflow can be combined with eligibility, formulary, and benefit coordination capabilities before the final prescription is transmitted.
LogiCoy has also achieved Surescripts Real-Time Prescription Benefit certification, extending the platform beyond basic prescription transmission into point-of-prescribing coverage and cost intelligence.
Benefit Coordination
Benefit coordination provides another layer of intelligence before a prescription is finalized. The LogiCoy eRx API suite includes capabilities for patient eligibility and coverage, formulary checks, benefit coordination, RTPB, and applying benefit information to medication workflows. The platform is designed so that these capabilities can be used before prescription transmission to improve coverage decisions, reduce avoidable prescription problems, and support medication affordability.
Notifications and Pharmacy-Initiated Workflows
Electronic prescribing is bidirectional. A complete e-prescribing integration must be able to receive information from pharmacies and respond to events—not simply send prescriptions.
The Notifications APIs provide structured access to prescription-related events such as:
- RxChange requests
- Refill requests
- Renewal requests
- Prior authorization events
- Other actionable pharmacy messages
Notifications can include patient and clinician context, priority, requested dates, due dates, reply requirements, and transaction type. This provides an important foundation for building an inbox or task-oriented prescription workflow inside an EHR or healthcare application.
Electronic Prescribing of Controlled Substances (EPCS) API
Controlled-substance prescribing introduces additional identity, authentication, authorization, and compliance requirements. LogiCoy eRx supports Electronic Prescribing of Controlled Substances (EPCS) workflows.
The platform includes controlled-substance service-level configuration and identity verification capabilities, including ID.me-based identity verification and MFA workflows for EPCS. The API platform is designed to incorporate EPCS-specific controls into the prescribing workflow rather than treating controlled-substance prescriptions as ordinary prescriptions.
This allows healthcare technology companies to build EPCS-capable prescribing workflows into their applications while using LogiCoy eRx as the underlying e-prescribing platform.
A Complete Electronic Prescribing Workflow
The individual APIs become particularly powerful when combined into an end-to-end workflow. For example, an EHR could implement a prescribing workflow like this:
This architecture allows the EHR or healthcare application to retain control of its own user experience while LogiCoy eRx provides the underlying electronic prescribing infrastructure.
REST APIs Designed for Healthcare Application Integration
LogiCoy eRx exposes its capabilities through REST-based APIs using structured request and response models. The APIs use HTTPS JSON endpoints with structured request and response models. Operations are submitted using POST, as documented in the vendor portal. LogiCoy provides detailed API documentation and interactive testing capabilities through its eRx vendor portal.
Security, Authorization, and Auditability
Healthcare APIs require more than functional endpoints. The LogiCoy eRx platform incorporates authorization and audit controls into its API architecture. API operations are designed around authenticated application access and practice, service-location, and clinician context.
Transactions also use transaction identifiers for traceability and audit purposes across prescription workflows. The OpenAPI specification describes audit logging and authorization controls across the platform, including additional validation for EPCS-related workflows. Detailed authentication and integration instructions are provided to authorized developers through the LogiCoy eRx vendor portal.
