Dynamics 365 CRM Integration Platform

.NET 8 microservices at Techverx that connect partner order systems and the HSV healthcare platform to Microsoft Dynamics 365, for healthcare transportation and interpretation. Five layers I worked on:

API Details screen I built on CCF: request status, business-rule result and the full log trail for one partner API call.

  1. 01 · Gateway

    One gateway, three services

    Built .NET 8 microservices for inbound partner orders, outward updates and the HSV healthcare platform, all behind an Ocelot API gateway secured with JWT, Keycloak and role-based authorization.

  2. 02 · Orders

    The full order lifecycle

    REST APIs take a partner order from creation through quotes, bill details, exception pricing, staffing status, record outcome, itinerary changes and cancellation.

  3. 03 · Rules

    Rules before anything is written

    A business rules engine validates quotes, bills, exception pricing and itinerary changes, and SmartyStreets / Google geocoding checks addresses, before any data reaches the CRM.

  4. 04 · CRM sync

    Clean data in Dynamics 365

    Orders, claimants, claims and referrals are written to Microsoft Dynamics 365 through the Dataverse SDK. Customizing CRM entities, workflows and data mappings cut manual processing by 30%.

  5. 05 · Operations

    Async work you can see

    RabbitMQ / MassTransit consumers and Redis caching keep processing off the request path, and API Calls / API Log dashboards on CCF show every request, CRM call and response, backed by Serilog, Grafana Loki and Prometheus.
