Docusign
Add Docusign to your product for your customers, and give your AI agents governed access to it.
Embed a Docusign integration so your customers can send documents for signature and follow envelope status from inside your product, using their own Docusign account, their own templates, and their own branding. Access runs through each customer's own grant, so their existing permissions apply and your product cannot read an envelope the connected account could not see itself. fastn handles per-customer OAuth and API upkeep, so onboarding a new signing account is configuration rather than a release.
In your product
Embedded for your customers. Per-tenant auth, no per-customer code, maintained by fastn.
Let customers send envelopes for signature from inside your product using their own Docusign account.
Populate their own templates with data from your product so nobody rebuilds a document by hand.
Read envelope and recipient status so your app shows who has signed without a chase email.
Trigger your product when an envelope is completed, declined, or voided.
For your AI agents
Governed, audited access for the agents you build, through the MCP server.
An agent checks which recipients are outstanding on an envelope before drafting a reminder.
An agent sends or voids an envelope within governed permissions, with the action audited.
An agent reacts to a completed signature and runs the next step of the workflow.
Example prompt
List envelopes sent more than five days ago that are still awaiting a signature and name the pending recipient.
Set up Docusign in 4 steps
- 01Open the Docusign connector from your fastn dashboard.
- 02Have each customer authenticate their Docusign account with OAuth.
- 03Map the templates and envelope fields your product uses, then enable actions and triggers.
- 04Call them from your product, or expose them to an agent through the MCP server.
Why teams use the Docusign integration
What you get by embedding it with fastn instead of building it yourself.
- Ship a Docusign integration without building it. Your customers connect their own Docusign 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 Docusign update is not your on-call problem.
- One integration serves your product and your agents. The same governed Docusign 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.

AsanaDocusign integration FAQ
How do I add a Docusign integration to my product?
Enable the Docusign connector in your fastn dashboard, then let each customer authenticate their own Docusign account. fastn handles the OAuth flow, token storage and refresh per tenant, so there is no Docusign client code in your app and no per-customer branch in your codebase. Setup is 4 steps.
Do my customers each connect their own Docusign account?
Yes. Every connection is scoped to the individual customer, so each authorises their own Docusign 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 Docusign 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 checks which recipients are outstanding on an envelope before drafting a reminder.
Who maintains the Docusign integration?
fastn does. When Docusign 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 Docusign integration run under?
Each customer's own Docusign grant. Where Docusign 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 Docusign automatically?
Where Docusign 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 Docusign integration?
A common starting point: send envelopes for signature from inside your product using their own Docusign account. 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 Docusign integration cost?
It is included. Pricing is based on connected accounts, not on how many connectors you enable, so adding Docusign does not change your per-connector cost. You can start free with 3 connected accounts.
