InsideSales.com
Add InsideSales.com to your product for your customers, and give your AI agents governed access to it.
Embed an InsideSales.com integration so your customers can work their own sales engagement records from inside your product. Every instance is customised, so field mapping is configuration per customer rather than code, and onboarding a team with an unusual setup does not require a deploy on your side. fastn handles per-customer authorisation, token refresh, and API upkeep, and records can be read, written, and reacted to through triggers so nothing drifts apart.
In your product
Embedded for your customers. Per-tenant auth, no per-customer code, maintained by fastn.
Let customers read their own leads and contacts into your product, mapped to their own fields.
Write activity back so calls, emails, and outcomes logged in your product appear against the right record.
Create or update a lead from your product so reps work it without switching tools.
Trigger your product when a lead is created, updated, or reaches a new stage.
For your AI agents
Governed, audited access for the agents you build, through the MCP server.
A sales copilot reads a lead's recent activity before it drafts a next touch.
An agent creates or updates a lead or contact within governed permissions, with every action logged.
An agent reacts to a stage change and runs the next step of a workflow.

Why teams use the InsideSales.com integration
What you get by embedding it with fastn instead of building it yourself.
- Ship an InsideSales.com integration without building it. Your customers connect their own InsideSales.com 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 an InsideSales.com update is not your on-call problem.
- One integration serves your product and your agents. The same governed InsideSales.com 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.

Google AdsInsideSales.com integration FAQ
How do I add an InsideSales.com integration to my product?
Enable the InsideSales.com connector in your fastn dashboard, then let each customer authenticate their own InsideSales.com account. fastn handles the OAuth flow, token storage and refresh per tenant, so there is no InsideSales.com client code in your app and no per-customer branch in your codebase. Setup is 4 steps.
Do my customers each connect their own InsideSales.com account?
Yes. Every connection is scoped to the individual customer, so each authorises their own InsideSales.com 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 InsideSales.com integration?
Yes. The same connection is exposed to your agents through the fastn MCP gateway, with permissions scoped per tenant and every call audited. A sales copilot reads a lead's recent activity before it drafts a next touch.
Who maintains the InsideSales.com integration?
fastn does. When InsideSales.com 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 InsideSales.com 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 InsideSales.com schema does not require a deploy on your side.
Can records sync both ways?
Yes. You can read from InsideSales.com, write back to it, and react to changes through triggers, so a record updated in your product and a record updated in InsideSales.com do not drift apart.
What can I build with the InsideSales.com integration?
A common starting point: read their own leads and contacts 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 InsideSales.com integration cost?
It is included. Pricing is based on connected accounts, not on how many connectors you enable, so adding InsideSales.com does not change your per-connector cost. You can start free with 3 connected accounts.
