Microsoft Dynamics GP
Add Microsoft Dynamics GP to your product for your customers, and give your AI agents governed access to it.
Embed a Microsoft Dynamics GP integration so your customers can keep using the Great Plains deployment they already run while working it from inside your product. GP is the legacy on-premise product in the Dynamics family, usually installed per company database behind the customer's own network boundary, so connection details and company selection are per-tenant configuration. fastn handles credential storage, retries and idempotent writes, so a timeout does not post the same document twice, and a customer who has not yet migrated to a cloud ERP is still a customer you can onboard.
In your product
Embedded for your customers. Per-tenant auth, no per-customer code, maintained by fastn.
Let customers connect their existing Great Plains company databases so your product reads customers, vendors, invoices and journal entries without a manual extract.
Write invoices and journal entries back into GP so your product does not depend on someone re-keying them.
Handle each customer's own company structure, account format and fiscal periods as mapping instead of code.
Onboard customers still running GP alongside those on a cloud ERP, without a second integration codebase for the legacy one.
For your AI agents
Governed, audited access for the agents you build, through the MCP server.
An agent reads aged receivables from the customer's GP company before answering a collections question.
An agent prepares a journal entry for a human to approve, within governed permissions and with the write logged.
An agent reconciles a payment against an open invoice and reports what it matched.
Example prompt
Summarise aged receivables by customer for this GP company and list anything more than 60 days overdue.
Set up Microsoft Dynamics GP in 4 steps
- 01Open the Microsoft Dynamics GP connector from your fastn dashboard.
- 02Have each customer supply their own GP connection details and the company databases in scope, stored encrypted per tenant.
- 03Map the documents, accounts and fields your product uses, then enable the actions you need.
- 04Call them from your product, or expose them to an agent through the MCP server.
Why teams use the Microsoft Dynamics GP integration
What you get by embedding it with fastn instead of building it yourself.
- Ship a Microsoft Dynamics GP integration without building it. Your customers connect their own Microsoft Dynamics GP 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 GP update is not your on-call problem.
- One integration serves your product and your agents. The same governed Microsoft Dynamics GP 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 GP integration FAQ
How do I add a Microsoft Dynamics GP integration to my product?
Enable the Microsoft Dynamics GP connector in your fastn dashboard, then let each customer authenticate their own Microsoft Dynamics GP account. fastn handles the OAuth flow, token storage and refresh per tenant, so there is no Microsoft Dynamics GP 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 GP account?
Yes. Every connection is scoped to the individual customer, so each authorises their own Microsoft Dynamics GP 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 GP 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 aged receivables from the customer's GP company before answering a collections question.
Who maintains the Microsoft Dynamics GP integration?
fastn does. When Microsoft Dynamics GP 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 GP 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 GP 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 GP integration?
A common starting point: connect their existing Great Plains company databases so your product reads customers, vendors, invoices and journal entries without a manual extract. 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 GP integration cost?
It is included. Pricing is based on connected accounts, not on how many connectors you enable, so adding Microsoft Dynamics GP does not change your per-connector cost. You can start free with 3 connected accounts.
