Insider

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

Yes. Every connection is scoped to the individual customer, so each authorises their own Insider account and only ever sees their own campaigns, segments and subscribers. 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.

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 user's segment membership and engagement before suggesting the next campaign.

fastn does. When Insider 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.

Yes. Product events can start a campaign, add a contact to a segment, or enrol someone in a journey, so lifecycle messaging follows what a user actually did rather than a nightly export.

Yes. Results come back scoped per tenant, so your product can act on them without one customer's data mixing with another's. What you get depends on the channel: opens, clicks, bounces and unsubscribes where there are sends, and impressions, spend and conversions where there are campaigns.

A common starting point: sync user profiles and attributes from your product into their own Insider account. Teams also use it for the other use cases listed above, and expose it to agents for governed reads and writes.

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