WebhooksNew

Settings → Webhooks, done properly: "Send test" runs a bead down the wire to the endpoint and back in the answer's colour, and every delivery opens into its request and response.

Where it’s used

Developer dashboards
The Settings → Webhooks page of a product that sends events.
Payments and billing platforms
Let customers choose which events go to which URL.
Integration platforms
Show where events are sent and whether they arrived.
Delivery debugging
Inspect the request and response of a failed delivery.

What it handles for you

Webhook settings are usually a table of URLs and a “Send test” button that answers with a toast somewhere else. This shows the test as the request it is, and keeps every delivery inspectable.

Instead of wiring upan endpoints tablea Send test buttona deliveries loga request and response viewera Redeliver buttona secret revealan enable switch

Add endpoints with events
A URL and event chips. A bad URL shakes the field and says why.
Send test, visibly
A bead runs the wire to the endpoint, the chip pulses while it answers, and the bead returns in the answer’s colour with “200 OK in 182 ms”.
Every delivery is inspectable
Each shows its status, event, time and duration, and opens into the request and the response as JSON.
Redeliver
Send a delivery again and the new attempt arrives on top of the list.
The secret stays hidden
The signing secret is dots until someone asks to reveal it, with a copy button once shown.
Enable and delete safely
The enabled switch saves itself and goes back if it fails. Delete asks first.

Webhook settings are usually a table of URLs and a "Send test" button that answers with a toast somewhere else. Here every endpoint opens in place. The test is drawn as the request it is: a bead leaves your app and runs the hairline to the endpoint, the endpoint's chip pulses while it answers, and the bead comes home in the answer's colour as "200 OK in 182 ms" rolls in; the delivery lands on top of the list below. Every delivery opens into its request and response, the tab highlight sliding between them, and Redeliver sends it again: the new attempt arrives on top. The signing secret stays dots until you reveal it. Enabled is a switch that saves itself, and Delete stretches the bin into a confirm and folds the endpoint away. A new endpoint fades in on top, already open on Send test.

States

add: "Add endpoint" opens the form by height: the URL (https://, or http://localhost) and event chips whose checks draw in. A bad URL shakes the field and says why. The new endpoint fades down 6px out of a blur on top of the list, open, with focus on Send test.
open: A row opens by height in 460ms; its chevron turns. The first time, recent deliveries load (loadDeliveries) with a spinner, then fade in.
test: The bead fades in and runs the wire to the endpoint in 620ms; the endpoint's chip pulses a ring every 900ms until onTest resolves; the bead comes back in emerald (2xx), amber (3xx/4xx) or red (5xx, no answer) in 640ms. Then the status code and the milliseconds roll in, the button says Delivered or shakes and says Send again, and the delivery glides in on top of the list.
delivery: Each row shows the status code in its colour, the event, how long ago and how long the endpoint took. It opens by height into Request and Response (pretty-printed JSON); the tab highlight slides 360ms between them.
redeliver: Redeliver → Sending → Sent with a drawn check; the new attempt ("attempt 2") fades in on top while the rest glide down, and the endpoint's last status updates.
secret: Dots until Reveal (which says Revealing while onRevealSecret runs); then the secret fades in from a blur with a copy button whose icon draws a check, and Hide.
enable / delete: The switch's thumb is thrown with a slight overshoot and its label says Saving until onToggle resolves (or is thrown back if it throws). Delete endpoint stretches out of the bin; a check draws, then the endpoint folds away.

Usage

import { Webhooks } from "@/components/webhooks";<Webhooks  defaultValue={endpoints}  events={[{ value: "invoice.paid" }, { value: "customer.created" }]}  onCreate={(input) => api.createEndpoint(input)}  onTest={(endpoint, event) => api.sendTest(endpoint.id, event)}   // → the delivery  loadDeliveries={(endpoint, before) => api.deliveries(endpoint.id, before?.id)}/>

Depends on lucide-react, installed for you by the CLI along with the keyframes it needs.

Works with

Installs with it

Signed deliveries from your own route

The test route signs the body with the endpoint's secret, posts it with a 10 second timeout, times the answer and stores the delivery, which is exactly what the card shows. Real events go through the same function from your queue. With Svix or Hookdeck, these routes call their APIs instead and map the attempts to the same shape.

Props

Prop	Type	Description
events	{ value, description? }[]	Event types an endpoint can subscribe to.
onCreate	({ url, events }) => Promise<WebhookEndpoint>	Creates an endpoint: { id, url, events, enabled?, lastDelivery? }. Throw to keep the form and show the message.
onTest	(endpoint, event) => Promise<WebhookDelivery>	Sends a test and returns the delivery: { id, event, status (null for no answer), durationMs?, at, attempt?, request?, response? }.
loadDeliveries	(endpoint, before?) => Promise<WebhookDelivery[]>	Recent deliveries, newest first, loaded the first time an endpoint opens; before is the oldest one shown when paging back. Return an empty list when there are no more.
onRedeliver	(delivery, endpoint) => Promise<WebhookDelivery>	Sends a delivery again and returns the new attempt. Without it there is no Redeliver.
onRevealSecret	(endpoint) => Promise<string>	Fetches the signing secret when someone asks to see it. Without it the secret stays dots.
onToggle	(endpoint, enabled) => Promise<unknown>	Turns an endpoint on or off; the switch moves at once and goes back if this throws.
onDelete	(endpoint) => Promise<unknown>	Deletes an endpoint after a confirm.
value	WebhookEndpoint[]	Controlled endpoints. lastDelivery updates after every test and redelivery.
defaultValue	WebhookEndpoint[]	Starting endpoints when uncontrolled.
onValueChange	(endpoints) => void	Every add, toggle, delete and new delivery.
appName	stringdefault "Your app"	The near end of the test's wire.

Accessibility and motion

Each endpoint is a button with aria-expanded; its details are its own region. Deliveries are a list whose rows open with aria-expanded, and Request / Response is a tablist that arrows move between.
The test result ("200 OK in 182 ms") is a status message; adding, deleting, toggling and redelivering are announced too. The wire itself is for the eye only.
Status codes are told by number and word, not colour alone: 2xx emerald, 3xx and 4xx amber, 5xx and no answer red.
The bead and the pulse are Web Animations that only run while a test is in flight; deliveries glide with additive transforms (use-row-motion).
Reduced motion skips the bead, the pulse, the fades and the glides; results and rows still change in place.

Requirements

React 19, Tailwind CSS v4 and shadcn/ui theme variables (any style, light and dark). Icons from lucide-react.

The CLI also installs Text morph, Number roll, Status button.
