Demio
Add Demio to your product for your customers, and give your AI agents governed access to it.
Demio runs webinars, and the shape that matters is that an event has many sessions and a registrant belongs to a session rather than to the event. Getting that wrong is the standard bug: registrations attach to the wrong date and people are counted twice. Attendance is distinct from registration and only exists after the fact, so the interesting metric, who actually turned up, is a later read rather than part of the signup. Registration is the write most products want, because it lets a signup in your product become a webinar seat without the user visiting a second site. fastn scopes each customer's key and keeps the session addressing correct.
In your product
Embedded for your customers. Per-tenant auth, no per-customer code, maintained by fastn.
Let a customer connect their own Demio account so webinar registration happens inside your product.
Register an attendee against the correct session rather than the parent event.
Read attendance after the fact, which is the number that actually matters.
React when someone registers or attends, and update the record your product holds.
For your AI agents
Governed, audited access for the agents you build, through the MCP server.
An agent reports registration against attendance for a session and flags the drop-off.
An agent registers a contact within governed permissions, with the write audited per tenant.
An agent lists who registered but did not attend, for follow-up.
Example prompt
How many registered for this session and how many actually attended?
Set up Demio in 4 steps
- 01Enable the Demio connector from your fastn dashboard.
- 02Have each customer authorise their own Demio account, so calls run under their credentials rather than a shared key.
- 03Decide which meetings, calls and participants your product needs, map those fields, then enable the actions and triggers you want.
- 04Call it from your product and expose it to your agents through the same governed connection.
Why teams use the Demio integration
What you get by embedding it with fastn instead of building it yourself.
- Ship a Demio integration without building it. Your customers connect their own Demio account inside your product and work their meetings, calls and participants there, with no per-customer code on your side.
- Handle the part that actually costs time: a call or a meeting is a real-time event, so a missed join or a dropped recording cannot be retried later. fastn owns the auth, token refresh, rate limits, pagination and breaking-change fixes, so a Demio update is not your on-call problem.
- One integration serves your product and your agents. The same governed Demio connection powers in-product features and gives AI agents scoped, audited access, so you let your product act on the conversations that happen by voice and video, not just the written ones without wiring it twice.

CalendlyDemio integration FAQ
How do I add a Demio integration to my product?
Enable the Demio connector in your fastn dashboard, then let each customer authenticate their own Demio account. fastn handles the OAuth flow, token storage and refresh per tenant, so there is no Demio client code in your app and no per-customer branch in your codebase. Setup is 4 steps.
Do my customers each connect their own Demio account?
Yes. Every connection is scoped to the individual customer, so each authorises their own Demio account and only ever sees their own meetings, calls and participants. 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 Demio 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 registration against attendance for a session and flags the drop-off.
Who maintains the Demio integration?
fastn does. When Demio 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 my product schedule or act on Demio conversations automatically?
Yes. Within the permissions each customer grants, your product can create a meeting, place or route a call, add participants, or react when one ends, all inside their own Demio account rather than through a shared one.
Can I get recordings, transcripts and outcomes back from Demio?
Yes, scoped per tenant and audited. This matters more here than in most integrations, because the substance of a call usually exists only in its recording or transcript, so a read that fails silently loses the thing you wanted.
What can I build with the Demio integration?
A common starting point: let a customer connect their own Demio account so webinar registration happens inside your product. 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 Demio integration cost?
It is included. Pricing is based on connected accounts, not on how many connectors you enable, so adding Demio does not change your per-connector cost. You can start free with 3 connected accounts.
