Real-Time Integration with Dynamics 365 Finance & Operations Using Azure Event Hub & Logic Apps (F&O as Source System)

Most organizations think of Dynamics 365 Finance & Operations (D365 F&O) only as a system that receives data from other applications. In reality, the most powerful and scalable architecture is when F&O itself becomes the source of truth and an event producer.

Every financial transaction, inventory update, order confirmation, or invoice posting is a critical business event – and when these events are not shared with other systems in real time, businesses face:

• a. Delayed updates in downstream systems
• b. Mismatched data between applications
• c. Manual reconciliation
• d. Outdated reporting

So, the real question is:

What if every critical event in D365 F&O could instantly trigger actions in other systems?

The answer lies in an event-driven architecture using Azure Event Hub and Azure Logic Apps, where F&O becomes the producer of events and the rest of the enterprise becomes real-time listeners.

Event-Driven Model with F&O as Source

In this model, whenever a business event occurs inside Dynamics 365 F&O, an event is immediately published to Azure Event Hub. That event is then picked up by Azure Logic Apps and forwarded to downstream systems such as:

• a. CRM systems
• b. Data warehouses
• c. eCommerce platforms
• d. Power BI
• e. Third-party logistics applications
• f. Notification systems

In simple terms:

Event occurs in F&O → Event is pushed to Event Hub → Logic App processes → External system is updated

This enables true real-time integration across your entire IT ecosystem.

Why Use Azure Event Hub Between F&O and Other Systems?

Azure Event Hub is designed for high-throughput, real-time event ingestion. This makes it the perfect choice for capturing business transactions from F&O.

Azure Event Hub provides:

• a. Millions of events per second
• b. Partitioned data streaming
• c. Event retention for replay
• d. High availability and fault tolerance
• e. Near-zero latency

This ensures that every change in F&O is captured and made available in real time to any subscribed system.

Technical Architecture

Here is the architecture with F&O as the source:

       Azure Event Hub
            ↓
       Azure Logic App

Role of each layer:

This architecture is:
✔ Decoupled
✔ Scalable
✔ Secure
✔ Real-time
✔ Fault tolerant

How Does D365 F&O Send Events to Event Hub?

Using Business Events

F&O has built-in Business Events Framework which can be configured to trigger events such as:

• 1. Sales order confirmed
• 2. Invoice posted
• 3. Purchase order approved
• 4. Vendor created
• 5. Inventory adjusted

These business events can be configured to push data to an Azure Event Hub endpoint.

This is the cleanest, lowest-code, and recommended approach.

Logic App as Event Consumer (Real-Time Processing)

Azure Logic App is connected to Event Hub via Event Hub Trigger:

When events are available in Event Hub

Once triggered, the Logic App performs:

• 1. JSON parsing
• 2. Business rule validation
• 3. Mapping to target system schema
• 4. API calls to external systems
• 5. Logging & monitoring

Example downstream actions:

This allows one F&O event to trigger multiple automated actions across platforms in real time.

Real-Time Example: Invoice Posted in F&O

Step-by-step flow:

1. Finance user posts an invoice in F&O
2. F&O Business Event fires
3. JSON event is published to Event Hub
4. Logic App picks up the event
5. Logic App sends data to:
   • – CRM for customer visibility
   • – Data Warehouse for reporting
   • – Power BI for dashboard updates
6. Status is logged in App Insights

All of this happens automatically, within seconds.

This is true enterprise-wide automation.

Key Technical Benefits

1. No polling required
   Systems don’t check for data — they receive it instantly.
2. Single Source of Truth
   F&O remains the authoritative system.
3. Asynchronous processing
   No performance impact on F&O users.
4. Supports microservices architecture
   Multiple systems can consume the same event independently.
5. Built for the future
   Supports AI, analytics, and real-time monitoring scenarios.

Why this Architecture is important for Technical Leaders

If you are a CTO, architect, or technical lead, this approach helps you:

• Move towards event-driven enterprise
• Eliminate batch-based integrations
• Enable real-time business insights
• Improve system performance
• Ensure data consistency
• Future-proof your architecture

Instead of systems “asking” for data, they react to real-time business events.

To conclude, by making Dynamics 365 Finance & Operations the event source and combining it with Azure Event Hub and Azure Logic Apps, organizations can create a fully automated, real-time, intelligence-driven ecosystem.

Your first step:

➡ Identify a critical business event in F&O
➡ Publish it to Azure Event Hub
➡ Use Logic App to trigger automatic actions

This single change can transform your integration strategy from reactive to proactive.
