Microsoft Dynamics 365 Business Central
Add Microsoft Dynamics 365 Business Central to your product for your customers, and give your AI agents governed access to it.
Embed a Microsoft Dynamics 365 Business Central integration so your customers can work their own small and mid-size business ERP from inside your product instead of exporting documents by hand. Business Central is deployed per environment and per company, and every company has its own dimensions, posting groups and number series, so those are mapped per tenant as configuration rather than code. fastn handles per-customer OAuth against each environment, token refresh, pagination and API upkeep, and writes are idempotent so a retry after a timeout does not post a document twice.
In your product
Embedded for your customers. Per-tenant auth, no per-customer code, maintained by fastn.
Let customers connect their own Business Central environment so your product reads their customers, vendors, items and posted invoices without a CSV export.
Create sales orders, sales invoices and purchase invoices from your product so a finance user never re-keys data your product already holds.
Map each company's own dimensions, posting groups and number series per tenant, so an unusual setup needs no release from you.
Trigger your product when a document is posted or a customer record changes, instead of polling the API on a schedule.
For your AI agents
Governed, audited access for the agents you build, through the MCP server.
An agent reads open sales orders and customer balances before answering a question about an account.
An agent drafts a sales invoice within governed permissions, with the write logged and attributable per tenant.
An agent reacts to a posted document and runs the next step of an approval workflow.
Example prompt
List open sales orders older than 30 days with the customer's outstanding balance and flag anything past its due date.

Why teams use the Microsoft Dynamics 365 Business Central integration
What you get by embedding it with fastn instead of building it yourself.
- Ship a Microsoft Dynamics 365 Business Central integration without building it. Your customers connect their own Microsoft Dynamics 365 Business Central account inside your product and work their invoices, payments and vendors there, with no per-customer code on your side.
- Handle the part that actually costs time: financial writes must be idempotent and reconcilable, because a duplicate is an accounting problem rather than a bug. fastn owns the auth, token refresh, rate limits, pagination and breaking-change fixes, so a Microsoft Dynamics 365 Business Central update is not your on-call problem.
- One integration serves your product and your agents. The same governed Microsoft Dynamics 365 Business Central connection powers in-product features and gives AI agents scoped, audited access, so you move financial records without hand-keying them between systems without wiring it twice.

AfterShipMicrosoft Dynamics 365 Business Central integration FAQ
How do I add a Microsoft Dynamics 365 Business Central integration to my product?
Enable the Microsoft Dynamics 365 Business Central connector in your fastn dashboard, then let each customer authenticate their own Microsoft Dynamics 365 Business Central account. fastn handles the OAuth flow, token storage and refresh per tenant, so there is no Microsoft Dynamics 365 Business Central client code in your app and no per-customer branch in your codebase. Setup is 4 steps.
Do my customers each connect their own Microsoft Dynamics 365 Business Central account?
Yes. Every connection is scoped to the individual customer, so each authorises their own Microsoft Dynamics 365 Business Central account and only ever sees their own invoices, payments and vendors. That per-tenant isolation is the point of an embedded integration: you support the long tail of customer setups without maintaining an integration per customer.
Can AI agents use this Microsoft Dynamics 365 Business Central integration?
Yes. The same connection is exposed to your agents through the fastn MCP gateway, with permissions scoped per tenant and every call audited. An agent reads open sales orders and customer balances before answering a question about an account.
Who maintains the Microsoft Dynamics 365 Business Central integration?
fastn does. When Microsoft Dynamics 365 Business Central changes an endpoint, deprecates a field or alters its auth, the fix lands in the connector rather than in your backlog, and your customers' connections keep working.
Is the Microsoft Dynamics 365 Business Central integration safe for financial writes?
Writes are idempotent, so a retry after a timeout does not post a document twice, and every call is logged per tenant so an entry can be traced back to the event that created it. That matters more in finance than anywhere else, because a duplicate is a number somebody has to explain.
Can it handle each customer's own chart of accounts?
Yes. ERP deployments are configured to the business, so account structures, required fields and fiscal calendars differ per customer. Those are mapped per tenant as configuration, not hard-coded.
What about Microsoft Dynamics 365 Business Central rate limits during a first import?
Backfills are throttled deliberately. ERP limits are often account-wide rather than per-integration, so an unthrottled import can exhaust a customer's allowance and disrupt their other integrations.
What can I build with the Microsoft Dynamics 365 Business Central integration?
A common starting point: connect their own Business Central environment so your product reads their customers, vendors, items and posted invoices without a CSV export. Teams also use it for the other use cases listed above, and expose it to agents for governed reads and writes.
How much does the Microsoft Dynamics 365 Business Central integration cost?
It is included. Pricing is based on connected accounts, not on how many connectors you enable, so adding Microsoft Dynamics 365 Business Central does not change your per-connector cost. You can start free with 3 connected accounts.
