Google Docs
Add Google Docs to your product for your customers, and give your AI agents governed access to it.
The Google Docs API is not a text editor. A document is a tree of structural elements, paragraphs, tables, inline objects and named ranges, and you change it by sending a batchUpdate: a list of requests applied in order, each addressed by an index into the document. That is where care is needed, because indexes shift as earlier requests in the same batch land, and a document somebody else is editing at the same moment moves underneath you. Reading the current revision, building the batch against it and keeping requests order-aware is the difference between a clean insert and mangled text. Sharing and permissions live in Drive rather than here. fastn holds the per-user authorisation and tracks Google's API changes.
In your product
Embedded for your customers. Per-tenant auth, no per-customer code, maintained by fastn.
Let a customer authorise their own account so your product writes into documents they already own.
Generate a document from your product's data by sending one ordered batch of requests rather than many calls.
Write into named ranges so a template keeps its structure while your product fills it in.
Read a document's structure to pull out the section your product needs without scraping the whole body.
For your AI agents
Governed, audited access for the agents you build, through the MCP server.
An agent reads a document's headings and tables before answering a question about the contents.
An agent inserts an approved paragraph, with the document and the revision it wrote against recorded.
An agent reports which named ranges a template exposes before anyone fills one in.
Example prompt
Fill the named ranges in this proposal template with the account details and leave the rest untouched.
Set up Google Docs in 4 steps
- 01Enable the Google Docs connector from your fastn dashboard.
- 02Have each customer authorise their own Google Docs account, so calls run under their credentials rather than a shared key.
- 03Decide which files, documents and versions your product needs, map those fields, then enable the actions and triggers you want.
- 04Call it from your product and expose it to your agents through the same governed connection.
Why teams use the Google Docs integration
What you get by embedding it with fastn instead of building it yourself.
- Ship a Google Docs integration without building it. Your customers connect their own Google Docs 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 Google Docs update is not your on-call problem.
- One integration serves your product and your agents. The same governed Google Docs 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.

AsanaGoogle Docs integration FAQ
How do I add a Google Docs integration to my product?
Enable the Google Docs connector in your fastn dashboard, then let each customer authenticate their own Google Docs account. fastn handles the OAuth flow, token storage and refresh per tenant, so there is no Google Docs client code in your app and no per-customer branch in your codebase. Setup is 4 steps.
Do my customers each connect their own Google Docs account?
Yes. Every connection is scoped to the individual customer, so each authorises their own Google Docs 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 Google Docs 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 headings and tables before answering a question about the contents.
Who maintains the Google Docs integration?
fastn does. When Google Docs 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 Google Docs integration run under?
Each customer's own Google Docs grant. Where Google Docs 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 Google Docs automatically?
Where Google Docs 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 Google Docs integration?
A common starting point: let a customer authorise their own account so your product writes into documents they already own. 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 Google Docs integration cost?
It is included. Pricing is based on connected accounts, not on how many connectors you enable, so adding Google Docs does not change your per-connector cost. You can start free with 3 connected accounts.
