AVImark is a Windows server-based veterinary practice management system from Covetrus, in use since the 1980s and still one of the most widely installed on-premises PIMS in North America. This page is an independent design exercise that asks what a well-designed AVImark API could look like: the resources it would expose, the authentication it would need, and the workflows it could unlock. Below: a hypothetical endpoint design, the technical requirements a production implementation would face, the use cases programmatic access could serve, and where to start if your team needs this kind of access today.

This page is an independent analysis by Supergood of what a well-designed AVImark API could look like. It draws on publicly available information, vendor materials, and general integration experience in this category. Nothing on this page describes an existing AVImark product, and Supergood is not affiliated with or endorsed by the vendor. If the vendor offers an official API, we highly recommend it.
AVImark is a Windows server-based veterinary practice management system from Covetrus, in use since the 1980s and still one of the most widely installed on-premises PIMS in North America. Practices run scheduling, medical records, billing, and inventory locally at the clinic, with a notes glossary for consistent clinical documentation, a centralized whiteboard for tracking patient activity and assigning tasks, and integrated Covetrus tools, vRxPro digital prescribing, Covetrus Comms client messaging and telemedicine, and EMV/PCI DSS-compliant payment processing.
Core product areas include:
An API for a platform like this would naturally organize around its core data entities:
Thousands of veterinary hospitals run AVImark as their clinical and financial system of record, but getting data in and out programmatically is one of the hardest problems in the veterinary software ecosystem:
If AVImark exposed a modern, general-purpose API, the integration challenges above suggest what it would need to get right. This is a design sketch, not documentation of anything that exists today:
The endpoint sketches, technical requirements, and use cases below flesh out this hypothetical design.

If your team needs this kind of access today, Supergood builds integrations on request, one customer at a time. We act at the direction of our customers, within the access they already hold. Customers bring their own accounts, licenses, and entitlements. If the vendor offers an official API, we highly recommend it.
Authentication
/authenticateWould establish an authenticated session with your AVImark system
Patient Operations
/patientsWould retrieve patients with owner/client details, species, breed, and status
Scheduling
/appointmentsWould list appointments with provider, patient, reason, and schedule details
Clinical
/medical_recordsWould fetch medical history, treatments, notes, and prescriptions for a patient
Billing
/invoicesWould retrieve invoices, line items, payments, and client account balances
Inventory
/inventoryWould read inventory items, stock levels, and pricing
- Sync clients, patients, and appointments into engagement and reminder platforms - Trigger confirmations, recalls, and post-surgery follow-ups from live AVImark data - Write communication outcomes back to the patient record
- Pull invoices, production, and inventory across every AVImark server you operate - Consolidate revenue and compliance metrics into one BI dashboard - Eliminate manual end-of-day exports from each clinic
- Read prescriptions and refill requests as they are recorded - Keep external pharmacy and inventory systems in sync with dispensing activity - Reconcile stock levels against invoiced items automatically
- Extract complete patient histories, invoices, and client data from on-prem AVImark - Feed cloud systems, data warehouses, or acquisition due-diligence workflows - Maintain a continuously updated off-site copy of the clinical record
Automate this platform from the no-code stack you already use.
Authentication
Would require managed credential-based login with encrypted credential storage
Connectivity
Would build on works with on-premises AVImark Windows server deployments via a secure connector
Response format
Normalized JSON over REST
Rate limits
Managed throttling tuned to your AVImark environment
Session management
Would need automatic session establishment, refresh, and recovery
Data freshness
On-demand reads against the live system, no batch export cycles
Security
Credentials encrypted at rest and in transit; least-privilege access
Webhooks
Change-detection events for new and updated records
Latency
Design target: typically seconds per request, depending on clinic environment
Throughput
Design target: paginated batch retrieval for large patient and invoice datasets
Reliability
Continuous monitoring with automatic retries and alerting
Versioning
Clear versioning and change management would matter as AVImark evolves
Patients, clients, appointments, medical records, treatments, prescriptions, invoices, payments, and inventory, normalized into consistent JSON objects. Read and write operations are scoped to what your workflows require.
Availability of official interfaces varies by product, plan, and licensing. Many platforms in this category gate access behind partner programs or paid modules, and there is often no broadly available, self-serve public API. Check the vendor's developer resources for current offerings.
The hard parts would be authentication (MFA, session management, enterprise controls), consistent schemas across the platform's products, and write semantics that reconcile the way the platform's own workflows do.

Supergood acts at the direction of its customers, within the access those customers already have. We respect each customer's agreements with their software vendors, and how those agreements apply to a customer's use is a determination the customer makes. If the vendor offers an official API, we highly recommend it.
Supergood builds managed API access to enterprise software for customers on request, scoped to each customer's own licensing and entitlements. If your team needs programmatic access to a platform like this, schedule an integration assessment to discuss options.
