Terminus
Add Terminus to your product for your customers, and give your AI agents governed access to it.
Terminus runs marketing at the account rather than at the lead, so the unit everything hangs off is a list of target accounts and the audiences built from it. An embedded Terminus integration pushes the accounts your product already knows are worth targeting, keeps those lists current as they qualify or churn, launches display and social advertising against them, and reads spend, impressions and account engagement back so your own reporting can show what the money bought. One fact belongs on the page rather than buried: Terminus merged into DemandScience in November 2024, and the account-based advertising and account experience capability now sits under the DemandScience brand, so the platform a customer logs into may not carry the Terminus name any more. Credentials stay with fastn, scoped to the customer that granted them, and interface changes land in the connector.
In your product
Embedded for your customers. Per-tenant auth, no per-customer code, maintained by fastn.
Let each customer connect their own account-based platform so the target accounts your product identifies become a list they can actually advertise against.
Keep a target account list current from your own signals, adding accounts as they qualify and removing them when they close or churn.
Start advertising against an audience when something in your product says the account is in market, rather than waiting for a quarterly list upload.
Read spend, impressions and account engagement back per tenant, so reporting in your product closes the loop rather than only pushing data outward.
For your AI agents
Governed, audited access for the agents you build, through the MCP server.
An agent reports which target accounts have had advertising spend against them and no engagement to show for it.
An agent adds or removes accounts from a list within scoped permissions, with each change attributed to the tenant that authorised it.
An agent explains which audience an account sits in and why it was added there.
Example prompt
Which target accounts have we spent against this quarter with no lift in engagement?
Set up Terminus in 4 steps
- 01Enable the Terminus connector in your fastn dashboard.
- 02Have each customer supply credentials for their own account, noting that the platform now sits under the DemandScience brand after the 2024 merger.
- 03Map the account, list and audience fields your product uses, then decide which advertising actions you want to expose.
- 04Call it from your product and expose the same connection to your agents through the MCP gateway.
Why teams use the Terminus integration
What you get by embedding it with fastn instead of building it yourself.
- Ship a Terminus integration without building it. Your customers connect their own Terminus account inside your product and work their campaigns, segments and subscribers there, with no per-customer code on your side.
- Handle the part that actually costs time: engagement data arrives as a high-volume event stream, so ordering and deduplication matter. fastn owns the auth, token refresh, rate limits, pagination and breaking-change fixes, so a Terminus update is not your on-call problem.
- One integration serves your product and your agents. The same governed Terminus connection powers in-product features and gives AI agents scoped, audited access, so you trigger and measure campaigns from inside your product without wiring it twice.

Terminus integration FAQ
How do I add a Terminus integration to my product?
Enable the Terminus connector in your fastn dashboard, then let each customer authenticate their own Terminus account. fastn handles the OAuth flow, token storage and refresh per tenant, so there is no Terminus client code in your app and no per-customer branch in your codebase. Setup is 4 steps.
Do my customers each connect their own Terminus account?
Yes. Every connection is scoped to the individual customer, so each authorises their own Terminus 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.
Can AI agents use this Terminus 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 reports which target accounts have had advertising spend against them and no engagement to show for it.
Who maintains the Terminus integration?
fastn does. When Terminus 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.
Can I trigger a Terminus campaign from an event in my product?
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.
Can I read engagement results back from Terminus?
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.
What can I build with the Terminus integration?
A common starting point: let each customer connect their own account-based platform so the target accounts your product identifies become a list they can actually advertise against. 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 Terminus integration cost?
It is included. Pricing is based on connected accounts, not on how many connectors you enable, so adding Terminus does not change your per-connector cost. You can start free with 3 connected accounts.
