Creates durable webhook handlers in Amp plugins running in Orbs. Use when asked to create, configure, or test a plugin webhook.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Creating Webhooks
Use `amp.createWebhook` to add a durable HTTP webhook to an Amp plugin running in an
Amp-managed Orb. Project threads owned by the same user share a registration for each plugin and
key. Threads without a project keep separate registrations.
## Workflow
1. Inspect the plugin and run `amp plugins show-docs` if the locally installed Plugin API is
unclear.
2. Choose a short, stable `key` for the webhook's logical purpose. Never generate the key at
runtime. Re-registering the same key in its scope restores the same URL after plugin reloads
and Orb restarts.
3. Register the handler from the plugin entry point so every plugin load reinstalls it:
```ts
const { url } = await amp.createWebhook({
key: 'deploy',
headers: ['x-hub-signature-256'],
handler: async (event, ctx) => {
await verifyAndApply(event.id, event.body, event.headers['x-hub-signature-256'], ctx.signal)
},
})
```
4. Load or reload the plugin, then give the capability URL to the user through the least exposed
local channel available.
5. Test with representative payloads, duplicate deliveries using the same event ID, handler
failures, and cancellation.

How to install
mdr add ampcode/official-plugins/creating-webhooks@sha256:5d5729ea789fc834The line at the top of this page pins the label git:20260929.7201b9d, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
