Microsoft Word
Add Microsoft Word to your product for your customers, and give your AI agents governed access to it.
Embed a Microsoft Word integration so your product produces and reads the documents your customers actually work in, filed in their own storage rather than downloaded from yours. Word documents live in the customer's OneDrive or SharePoint, so a document your product creates keeps the folder's permissions and version history instead of starting a parallel copy. fastn handles per-tenant OAuth, token refresh, upload sessions for larger documents and API upkeep, so contract drafts, reports and letters are generated where the customer expects to find them.
In your product
Embedded for your customers. Per-tenant auth, no per-customer code, maintained by fastn.
Let customers connect their own Microsoft 365 account so your product reads the Word documents they point it at.
Generate a document from a template and data your product already holds, then save it to the customer's folder.
Convert a document to PDF for signature or archiving, without running a conversion service yourself.
Create each new draft as a version in the customer's own document, so history stays where their team looks for it.
For your AI agents
Governed, audited access for the agents you build, through the MCP server.
An agent reads a document's text before answering a question about its contents.
An agent drafts a document and files it in the folder you scope it to, with the write logged.
An agent produces a PDF of an approved draft and returns the link, within governed permissions.
Example prompt
Draft the renewal letter for this account from our template, save it to the client folder and give me a PDF.
Set up Microsoft Word in 4 steps
- 01Open the Microsoft Word connector from your fastn dashboard.
- 02Have each customer authenticate their own Microsoft 365 account with the file scopes your product needs.
- 03Choose the templates and folders your product writes to, 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 Word integration
What you get by embedding it with fastn instead of building it yourself.
- Ship a Microsoft Word integration without building it. Your customers connect their own Microsoft Word account inside your product and work their files, documents and versions there, with no per-customer code on your side.
- Handle the part that actually costs time: permissions and versioning are easy to get subtly wrong, and mistakes expose content. fastn owns the auth, token refresh, rate limits, pagination and breaking-change fixes, so a Microsoft Word update is not your on-call problem.
- One integration serves your product and your agents. The same governed Microsoft Word connection powers in-product features and gives AI agents scoped, audited access, so you let your product work with your customers' documents in place without wiring it twice.

AsanaMicrosoft Word integration FAQ
How do I add a Microsoft Word integration to my product?
Enable the Microsoft Word connector in your fastn dashboard, then let each customer authenticate their own Microsoft Word account. fastn handles the OAuth flow, token storage and refresh per tenant, so there is no Microsoft Word 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 Word account?
Yes. Every connection is scoped to the individual customer, so each authorises their own Microsoft Word account and only ever sees their own files, documents and versions. 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 Word 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 a document's text before answering a question about its contents.
Who maintains the Microsoft Word integration?
fastn does. When Microsoft Word 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.
Whose permissions does the Microsoft Word integration run under?
Each customer's own Microsoft Word grant. Where Microsoft Word holds a library, their existing folder and item permissions apply and your product cannot reach content the connected account could not reach itself. Where it processes content you supply rather than storing it, the call runs under that customer's own credentials and is logged per tenant.
Can my product create or update content in Microsoft Word automatically?
Where Microsoft Word supports writes, documents, entries and assets can be created, updated and filed from your product or by an agent within scoped permissions, with each action logged. Where it is a read surface, the same connection serves reads only.
What can I build with the Microsoft Word integration?
A common starting point: connect their own Microsoft 365 account so your product reads the Word documents they point it at. 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 Word integration cost?
It is included. Pricing is based on connected accounts, not on how many connectors you enable, so adding Microsoft Word does not change your per-connector cost. You can start free with 3 connected accounts.
