API integration across the Microsoft Dynamics ecosystem
REST and OData integrations between Dynamics 365, Power Platform, Azure and third-party applications, designed for authentication, throttling, retries and supportability.
The challenge
An API call that works in Postman isn't yet an integration. Production needs authentication that renews, limits that are respected, idempotent writes and someone alerted when a message fails.
Technology we use
How we approach it
The same four steps apply whether the project is a rollout, an integration or a fix. Only the depth changes.
Read the contract
Endpoints, limits, authentication and error semantics of every system involved.
Design the flow
Synchronous or queued, push or pull, single record or batch.
Implement
Middleware, AL code or flows, with structured logging.
Operate
Monitoring, replay of failed messages and documentation for support.
