cursor-origin-axiom

Send Cursor Origin webhook events straight into Axiom. One serverless function, zero dependencies. Deploy your own copy for free — your data never touches anyone else's infrastructure.

Setup

1. In Axiom: create a dataset (e.g. origin) and an API token with ingest permission for it.
2. Click the deploy button above and set:
   • AXIOM_TOKEN — the Axiom API token
   • AXIOM_DATASET — the dataset name
   • AXIOM_URL — optional, defaults to https://api.axiom.co (set for EU region)
3. Open https://<your-deployment>.vercel.app — the setup page checks your config live and shows your webhook URL.
4. In Origin app settings, set your app's webhook URL to: https://<your-deployment>.vercel.app/api/webhook
5. Subscribe to the events you want. They land in your dataset within seconds.

What lands in Axiom

Each delivery is verified (Ed25519 signature against Origin's JWKS, 5-minute timestamp window) and flattened to:

{
  "_time": "<event.eventTime>",
  "type": "pull_request.merged",
  "eventId": "evt_01...",
  "deliveryId": "whd_01...",
  "appId": "app_01...",
  "installationId": "i_01...",
  "payload": { ... }
}

Failed Axiom ingests return 5xx so Origin redelivers (up to 6 retries). Deliveries are at-least-once — dedup on deliveryId in queries if exactness matters.

Starter queries (APL)

Field paths below are verified against real Origin events. pull_request.merged events carry both createdAt and mergedAt, so cycle time needs no joins:

['origin']
| where type == 'pull_request.merged'
| extend cycle_min = datetime_diff('minute',
    todatetime(['payload.pullRequest.mergedAt']),
    todatetime(['payload.pullRequest.createdAt']))
| summarize avg(cycle_min) by bin_auto(_time)

Push activity by author:

['origin']
| where type == 'repository.pushed'
| summarize count() by author = tostring(['payload.pusher.user.email']), bin_auto(_time)
