Gainsight

Add Gainsight to your product for your customers, and give your AI agents governed access to it.

Embed a Gainsight integration so your customers can work their own customer success data inside your product, covering companies, people, health scores, timeline activity, and calls to action. Every Gainsight instance is configured to the business, so custom fields and scoring setups are mapped per tenant rather than hard-coded. fastn handles per-customer authorisation and API upkeep, so onboarding another instance 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 sync their Gainsight companies and people into your product, mapped to their own fields.

Read health scores so your product can surface at-risk accounts where the team already works.

Create a call to action or log timeline activity from an event in your product.

Trigger your product when a health score changes or a call to action is opened or closed.

For your AI agents

Governed, audited access for the agents you build, through the MCP server.

An agent reads an account's health score and recent timeline activity before recommending a next step.

An agent opens or updates a call to action within governed permissions, with the action logged.

An agent reacts to a score change and gathers the context a CSM will need.

Example prompt

List accounts whose health score dropped this month and show the last timeline activity on each.

Set up Gainsight in 4 steps

  2. 02Have each customer authenticate their own Gainsight instance.
  3. 03Map the companies, people, and custom fields your product uses, then enable actions and triggers.
  4. 04Call them from your product, or expose them to an agent through the MCP server.

Why teams use the Gainsight integration

What you get by embedding it with fastn instead of building it yourself.

  • Ship a Gainsight integration without building it. Your customers connect their own Gainsight account inside your product and work their accounts, contacts and opportunities there, with no per-customer code on your side.
  • Handle the part that actually costs time: every CRM instance is customised, so standard objects are never the whole story. fastn owns the auth, token refresh, rate limits, pagination and breaking-change fixes, so a Gainsight update is not your on-call problem.
  • One integration serves your product and your agents. The same governed Gainsight connection powers in-product features and gives AI agents scoped, audited access, so you keep customer records aligned between your product and the CRM each customer already runs without wiring it twice.

Gainsight integration FAQ

How do I add a Gainsight integration to my product?

Enable the Gainsight connector in your fastn dashboard, then let each customer authenticate their own Gainsight account. fastn handles the OAuth flow, token storage and refresh per tenant, so there is no Gainsight client code in your app and no per-customer branch in your codebase. Setup is 4 steps.

Do my customers each connect their own Gainsight account?

Yes. Every connection is scoped to the individual customer, so each authorises their own Gainsight account and only ever sees their own accounts, contacts and opportunities. 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 Gainsight 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 an account's health score and recent timeline activity before recommending a next step.

Who maintains the Gainsight integration?

fastn does. When Gainsight 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.

Does the Gainsight integration support custom fields and custom objects?

Yes. CRM instances are heavily customised, so field and object mapping is configuration rather than code. Each customer maps their own fields during setup, which means onboarding a customer with an unusual Gainsight schema does not require a deploy on your side.

Can records sync both ways?

Yes. You can read from Gainsight, write back to it, and react to changes through triggers, so a record updated in your product and a record updated in Gainsight do not drift apart.

What can I build with the Gainsight integration?

A common starting point: sync their Gainsight companies and people into your product, mapped to their own fields. 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 Gainsight integration cost?

It is included. Pricing is based on connected accounts, not on how many connectors you enable, so adding Gainsight does not change your per-connector cost. You can start free with 3 connected accounts.
