A headless scheduling engine. We are the layer it does not ship.
Hapio exposes scheduling-event webhooks through a flexible headless API. Their documentation says it plainly: attribution, UTM handling, and offline conversion tracking are left to the implementer. Every Hapio implementation starts attribution from zero.
Independent comparison based on public documentation and pages. No paid rankings, no sales scores. Where the other tool is better, we say so.
Flexible headless API for building custom flows
Well-documented scheduling-event webhooks
Total UX freedom for product teams
Attribution is explicitly out of scope
It is the documented case: Hapio users build UTM handling, identity, and offline conversion by hand. Apointo is exactly that layer, ready.
From raw webhook to ad conversion there is a chasm
A raw event is not a verified conversion. Apointo does identity matching, deduplication, conversion windows, and Google Ads delivery.
No operator surface at all
Headless means assembling everything. Apointo ships a multi-tenant dashboard with per-client conversion status.
- You are BUILDING a scheduling product
- An engineering team wants to assemble its own stack
- Fully custom UX is worth the assembly cost
- You use a headless engine and attribution still does not exist
- You want the post-click layer ready instead of building it
- You need to prove campaign revenue without hiring a data team
