Microsoft Teams
Dynamics 365 integration tools, and when each earns its place
Power Automate
Cloud flows suit department-level automation with modest volumes. For example, a new account in Sales creates a folder in SharePoint. An approved quote posts a message in Teams. Quick to build, easy for power users to read.
Azure Logic Apps
The same connector idea with enterprise controls: source control, deployment pipelines, virtual network options and better handling of large volumes. Our default for anything finance depends on.
Dataverse Web API and plug-ins
When another application needs to read or write customer engagement data directly, the Web API is the front door. Plug-ins react inside Dataverse when timing must be exact.
Azure Service Bus and Functions
For high-volume or order-sensitive traffic, a queue between systems absorbs spikes. It also lets one side go offline without losing messages.
Dual-write
Microsoft's built-in link between Finance and Supply Chain Management and Dataverse. It keeps customers, products and orders aligned across ERP and CRM.
EDI through a provider
X12 documents such as 850 orders, 856 ship notices and 810 invoices usually arrive via an EDI provider. Then they land in Dynamics 365 through an API or file drop we build and watch.
Business Central APIs and webhooks
Standard and custom API pages expose Business Central data over REST with OAuth sign-in. Webhooks tell a subscriber when records change, so nothing has to poll constantly.
Virtual tables
Data from Finance and Supply Chain Management or another source shows up inside Dataverse with no copy. That suits CRM users who only need to read it.
Dual-write in Dynamics 365 integration services
Dual-write is attractive because it is Microsoft's own mechanism. It also ships with ready-made table maps for customers, vendors, products, sales orders and more. Turned on carelessly, though, it can create a tangle. Two systems may both edit the same record, or legal entity rules may differ from CRM ownership rules. Initial sync jobs can also stall on bad data.
Before switching it on, we decide which system owns each field, table by table. We also decide whether sync runs one way or both ways. First, we clean duplicate customers, because dual-write will faithfully copy every duplicate across. And we test the initial sync on a copy with realistic volumes, not the demo data in a sandbox.
Sometimes the right answer is not to use dual-write at all. If CRM only needs to read invoice history, a virtual table or a scheduled Logic App may be simpler.
Picking a Dynamics 365 integration pattern for each connection
How we watch every Dynamics 365 integration we ship
- ✓Each run writes a log entry with a correlation ID. So you can follow one order from the web shop to the invoice.
- ✓Transient errors retry on their own with a back-off. Permanent errors stop and go to a dead-letter queue instead of looping.
- ✓Failures raise an alert to a named mailbox or Teams channel. It carries enough detail for the reader to act.
- ✓Credentials live in Azure Key Vault or connection references, never inside flow definitions or code.
- ✓A plain-English runbook explains how to resubmit a failed message without calling us.
- ✓We review volumes and run times on a schedule. So we change a flow that nears a service limit before it starts failing.

Dynamics 365 integration services questions we hear most
Should we use Power Automate or Logic Apps?
Both use the same connectors, so the choice is about ownership and scale. Power Automate is a good fit when a business team will maintain a modest flow themselves. Logic Apps fits when IT needs source control, deployment pipelines, private networking or heavy volumes.
Can you connect Dynamics 365 to our ecommerce platform?
Yes. Most ecommerce platforms offer APIs or webhooks. We build a flow that creates customers and orders in Dynamics 365. It also sends stock and shipment updates back. The design decides which system owns prices, stock and customer details before anyone writes a mapping. Business Central users should also look at the dedicated Shopify connector, which Microsoft ships with the product.
Do we need a separate EDI provider?
Usually, yes. An EDI provider handles the trading partner connections, envelopes and acknowledgements, which is specialist work. We connect that provider to Dynamics 365 and build the document mapping and error handling on our side.
What happens when Microsoft updates Dynamics 365?
APIs change slowly, and Microsoft announces deprecations in advance. Still, connectors and dual-write maps do change. We test integrations in a sandbox with the upcoming release wave turned on. Then we fix anything that breaks before the update reaches production. Customers on our support service have this done as part of each wave.
Someone else built our integrations. Can you take them over?
Yes. We start by listing every connection and reading the flows and code. We also check where credentials live and who gets alerts. You receive a written assessment of what is solid and what is risky before we take responsibility for it. Then we rank fixes by how much business depends on each connection.
