description: >-
Demio has a real event surface — registration, join, no-show and series-update
notifications — but does not expose it as a first-party webhook API. The only published
delivery path is the Demio Zapier app, so an integrator cannot subscribe an endpoint of
their own without routing through Zapier and paying the Zapier tax. There is no
AsyncAPI document, no webhook endpoint registration, no event payload reference, no
signature scheme and no delivery or retry semantics anywhere on the Demio developer
surface. Because these events are not addressable through Demio's own contract, no
`Webhooks` and no `AsyncAPI` pointer is wired in apis.yml — recording one would credit
Demio for an event surface it does not actually serve.
delivery:
mechanism: partner-platform
platform: Zapier
app_docs: https://help.demio.com/en/articles/3527489-zapier-setup
customer_visible_endpoint: false
quota_note: >-
Zapier traffic consumes the same daily API-call quota as direct API calls (100/day on
a free trial, 5,000/day for paying customers), so an event subscription silently eats
the same budget as the REST integration.
events:
- name: New Webinar Registration
trigger: zapier
fires: When someone registers for a selected Event.
scope: per-Event (the Event is chosen from a dropdown when the Zap is built)
note: Covers all Event types, including Like Live Replays.
- name: Joins Webinar
trigger: zapier
fires: When an attendee joins a selected Event.
scope: per-Event
- name: Does Not Attend Webinar
trigger: zapier
fires: >-
When a webinar ends and a Registrant did not attend. Documented not to fire for
On-Demand Sessions, where Registrants may join at any time and are therefore not
treated as no-shows.
scope: per-Event
- name: Webinar Update
trigger: zapier
fires: >-
When a Session from a Series Event ends, so that fields — including the new
date/time and the Unique Join Link — can be updated for Registrants carried over.
scope: per-Event
actions:
- name: Create Registration for Webinar
platform: zapier
rest_equivalent: openapi/demio-openapi.yml#registerForEvent
gaps:
- No AsyncAPI or event-schema document is published.
- No customer-registerable webhook endpoints; Zapier is the only subscriber.
- No payload reference, no signature/verification scheme, no retry or ordering guarantees.
- >-
Triggers are bound to a single Event each — there is no account-wide event stream, so
an integration must be rebuilt every time a new Event is created.
