Webhooks: every event, to your own addresses, signed and retried

A new webhooks service subscribes to the event bus and delivers each event to the repository and workspace webhooks that want it: an HTTPS POST of JSON naming the repository, workspace and actor, signed with HMAC-SHA256 in X-G1t-Signature-256. A receiver that does not answer with a 2xx within ten seconds is tried again after 1m, 5m, 30m, 2h and 5h. Every delivery is kept for a fortnight with its request and response, and can be redelivered. Addresses must be public HTTPS; private and local ones are refused. Each event reaches a webhook once. Members manage a repository's webhooks under its settings, now with General and Webhooks tabs; owners manage the workspace's under Settings. Seven API and MCP tools cover both. The secret sealing that integrations used moves into a shared crate, g1t-secrets. Also: an address no route matches now shows its 404 inside the signed-in sidebar instead of the public frame.

2+title: Webhooks
3+description: Have g1t send a repository's or a workspace's events to your own address as they happen, signed and retried.
4+---
5+
6+A webhook sends events to an HTTPS address you choose, as they happen: a
7+push, an issue opened, a pull request merged, checks finished, the merge
8+queue moving. Use them to build on g1t: post to chat, start a deploy, keep
9+another system in step.
10+
11+A webhook belongs to one of two things:
12+
13+| | Sent the events of | Managed by | Where |
14+| --- | --- | --- | --- |
15+| A repository's | That repository | Members of its workspace | The repository's **Settings → Webhooks** |
16+| A workspace's | Every repository in the workspace | Owners | The workspace's **Settings → Webhooks** |
17+
18+## Add one
19+
20+1. Open **Settings → Webhooks** for the repository or the workspace.
21+2. Give the **payload URL**: an HTTPS address on the public internet.
22+3. Choose the events, or leave **Everything**, which also includes event
23+ types added later.
24+4. Give a **secret**, or leave it empty and g1t makes one. A secret g1t
25+ makes is shown once.
26+5. **Add webhook**. g1t sends it a `ping` at once, so you can see straight
27+ away whether your receiver answers.
28+
29+## What is sent
30+
31+Each delivery is a `POST` with a JSON body:
32+
33+```json
34+{
35+ "id": "evt_01m401tecce9h8wt7k3ayvs72n",
36+ "type": "comment.created",
37+ "time": "2026-10-03T04:54:37.708Z",
38+ "workspace": "acme",
39+ "repository": { "id": "rep_cf985171afeee00a62a1c0acb0", "fullName": "acme/web" },
40+ "actor": { "id": "usr_b51a1a09fc53e9471cbe1426b7", "username": "ada" },
41+ "data": { "commentId": "cmt_01m401te9eekb92kccgwhympr4", "number": 3, "repoId": "rep_cf985171afeee00a62a1c0acb0" }
42+}
43+```
44+
45+`data` holds what the event is about: ids and numbers to fetch the rest with
46+the [API](/reference/api/). `actor` is null for something g1t did by
47+itself.
48+
49+With these headers:
50+
51+| Header | |
52+| --- | --- |
53+| `X-G1t-Event` | The event type, such as `pull.merged`, or `ping`. |
54+| `X-G1t-Delivery` | The delivery's id. A redelivery has a new one. |
55+| `X-G1t-Hook` | The webhook's id. |
56+| `X-G1t-Signature-256` | `sha256=` and the HMAC-SHA256 of the body, keyed with the secret. |
57+| `User-Agent` | `g1t-webhooks/1` |
58+
59+## Events
60+
61+| Event | When |
62+| --- | --- |
63+| `git.push` | A branch moved. `data.ref`, `data.after`, `data.defaultBranch`. |
64+| `repo.created`, `repo.forked` | A repository was made, or forked for a pull request. |

97+## Answering, and retries
98+
99+Answer with any 2xx within 10 seconds. Do slow work after answering.
100+
101+A delivery that gets anything else, or no answer, is tried again after 1
102+minute, 5 minutes, 30 minutes, 2 hours and 5 hours: six attempts over
103+about seven and a half hours. Then it is marked failed. Pausing or removing
104+a webhook stops its retries.
105+
106+An event is delivered to a webhook once. Use `X-G1t-Delivery`, or the
107+event's `id`, to ignore one you have already handled.
108+
109+## The delivery log
110+
111+Each webhook keeps its deliveries for 14 days. Open **Deliveries** to see,
112+for each one, the request g1t sent, the status and body your receiver
113+answered with, how long it took, and when it will be tried again.
114+**Redeliver** sends the same payload again, as a new delivery.
115+
116+The status dot beside each webhook shows how its latest delivery went:
117+green delivered, amber waiting to try again, red failed.
118+
119+## Addresses
120+
121+Webhooks are sent only over HTTPS, to public addresses. Private and local
122+addresses (`localhost`, `10.0.0.0/8`, `192.168.0.0/16` and the like) are
123+refused. To receive webhooks on your own machine while you build, use a
124+tunnel such as Cloudflare Tunnel.
125+
126+## From the API
127+
128+The same tools work for a repository's webhooks (give `repo`) and a
129+workspace's (give `workspace` instead).
