Webhook Replay & Delivery IDs
Nothing missed, nothing twice.
Comment enseignez-vous ?
When your endpoint is down, webhooks are lost, and duplicates are hard to spot. We build a replay store you query for any time window, plus a delivery ID and dispatch timestamp on every webhook.
If your server goes down overnight, you lose that night’s attendance events. Replay any time window from a store, and deduplicate with a delivery ID on every webhook.
A missed webhook means a missing attendance record. Query undelivered webhooks for any time window and replay them, with IDs to deduplicate.
Compliance records can’t have gaps. Replay undelivered webhooks for any window, with delivery IDs and timestamps for clean ordering.
District systems need complete attendance data. Replay undelivered webhooks for any time window, with a delivery ID on each to avoid duplicates.
Replay undelivered webhooks for any time window, with delivery IDs and dispatch timestamps to keep records in order.
Parents won’t need this. It keeps a program’s lesson records complete even when its systems go down.

The problem
Missed webhooks mean missing records
When an endpoint is down, webhooks that can’t be delivered are lost. Retries create duplicates, and events arrive out of order.
La méthode habituelle
Engineers rebuild missing data from exports and write their own deduplication.
How Pencil Spaces solves it
Webhooks that could not be delivered are kept in a store you query for any time window, and every delivery carries its own ID and dispatch timestamp for deduplication.
Quels sont les changements ?
No gaps and no duplicates in the data your systems depend on.
What we build
- Pull-based replay for any time range
- A unique delivery ID on every webhook
- Dispatch timestamps for ordering
Typical build time: about 1 month.
What it looks like
Dans la pratique
A company’s endpoint goes down for two hours. Afterward, an engineer queries undelivered webhooks for that window, replays them and drops duplicates by delivery ID.
In a 1:1 lesson
After a deploy breaks your endpoint, you replay the afternoon’s webhooks and nothing is missing from payroll.
In a group class
You replay Monday’s undelivered events, and attendance for every class is complete.
In a virtual training
Your compliance report is complete, because a missed hour of events was replayed and ordered by timestamp.
In your classroom
The district’s attendance data has no gaps after a weekend outage, because the events were replayed.
In the training room
Events from a day of workshops are replayed in order after your system’s maintenance window.
At home
Parents won’t see this. It means your child’s attendance is never lost.
