RegOnline by Lanyon
Add RegOnline by Lanyon to your product for your customers, and give your AI agents governed access to it.
RegOnline was the self-service event registration product that Active Network acquired, that was consolidated under the Lanyon name in 2014, and that came to Cvent when Cvent acquired Lanyon in 2016; RegOnline itself stopped taking new accounts and was retired at the end of 2019, with its capabilities folded into Cvent Event Management. An embedded integration here is about the records organisers still hold: events, registrations, attendees, sessions and the custom registration questions each event asked, which are exactly the values that decide whether a migrated attendee list reconciles. Custom questions differ per event, so mapping is configuration per organiser rather than a fixed schema. For anything new, the Cvent connector is the current surface.
In your product
Embedded for your customers. Per-tenant auth, no per-customer code, maintained by fastn.
Let each organiser connect their own account so historical events, registrations and attendee records are reachable inside your product.
Read the custom registration questions an event asked, since those answers are usually the only place a detail was captured.
Reconcile a migrated attendee list against the records it came from, so past attendance survives a move to Cvent.
Support organisers mid-migration, where recent events already sit in Cvent and older ones do not.
For your AI agents
Governed, audited access for the agents you build, through the MCP server.
An agent answers what a past event's attendance actually was, from the record rather than from a summary.
An agent reports which events have already been migrated and which have not.
An agent flags attendee records that did not carry across, with every read logged.
Example prompt
Which of this organiser's past events still only exist as RegOnline records, and how many attendees did each have?

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

ApolloRegOnline by Lanyon integration FAQ
How do I add a RegOnline by Lanyon integration to my product?
Enable the RegOnline by Lanyon connector in your fastn dashboard, then let each customer authenticate their own RegOnline by Lanyon account. fastn handles the OAuth flow, token storage and refresh per tenant, so there is no RegOnline by Lanyon client code in your app and no per-customer branch in your codebase. Setup is 4 steps.
Do my customers each connect their own RegOnline by Lanyon account?
Yes. Every connection is scoped to the individual customer, so each authorises their own RegOnline by Lanyon 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 RegOnline by Lanyon 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 answers what a past event's attendance actually was, from the record rather than from a summary.
Who maintains the RegOnline by Lanyon integration?
fastn does. When RegOnline by Lanyon 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 RegOnline by Lanyon 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 RegOnline by Lanyon?
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 RegOnline by Lanyon integration?
A common starting point: let each organiser connect their own account so historical events, registrations and attendee records are reachable 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 RegOnline by Lanyon integration cost?
It is included. Pricing is based on connected accounts, not on how many connectors you enable, so adding RegOnline by Lanyon does not change your per-connector cost. You can start free with 3 connected accounts.
