Notifications

Gitea Mirror supports push notifications for mirror events. You can be alerted when jobs succeed, fail, or when new repositories are discovered.

Supported Providers

1. Ntfy.sh (Direct)

Ntfy.sh is a simple HTTP-based pub-sub notification service. You can use the public server at https://ntfy.sh or self-host your own instance.

Setup (public server):

1. Go to Configuration > Notifications
2. Enable notifications and select Ntfy.sh as the provider
3. Set the Topic to a unique name (e.g., my-gitea-mirror-abc123)
4. Leave the Server URL as https://ntfy.sh
5. Subscribe to the same topic on your phone or desktop using the ntfy app

Setup (self-hosted):

1. Deploy ntfy using Docker: docker run -p 8080:80 binwiederhier/ntfy serve
2. Set the Server URL to your instance (e.g., http://ntfy:8080)
3. If authentication is enabled, provide an Access token
4. Set your Topic name

Priority levels:

• min / low / default / high / urgent
• Error notifications automatically use high priority regardless of the default setting

2. Apprise API (Aggregator)

Apprise is a notification aggregator that supports 100+ services (Slack, Discord, Telegram, Email, Pushover, and many more) through a single API.

Setup:

1. Deploy the Apprise API server:

   # docker-compose.yml
   services:
     apprise:
       image: caronc/apprise:latest
       ports:
         - "8000:8000"
       volumes:
         - apprise-config:/config
   volumes:
     apprise-config:
   

2. Configure your notification services in Apprise (via its web UI at http://localhost:8000 or API)
3. Create a configuration token/key in Apprise
4. In Gitea Mirror, go to Configuration > Notifications
5. Enable notifications and select Apprise API
6. Set the Server URL to your Apprise instance (e.g., http://apprise:8000)
7. Enter the Token/path you created in step 3

Tag filtering:

• Optionally set a Tag to only notify specific Apprise services
• Leave empty to notify all configured services

3. Gotify (Direct)

Gotify is a simple self-hosted push notification server.

Setup:

1. In Gotify, create an application and copy its token
2. In Gitea Mirror, go to Configuration > Notifications
3. Enable notifications and select Gotify
4. Set the Server URL to your Gotify instance (e.g., https://gotify.example.com)
5. Paste the Application token
6. Pick a Default priority (0 to 10; error notifications are always sent at priority 8)

The token is encrypted at rest like all other provider credentials.

4. Webhook (Generic)

Sends a plain JSON POST to any URL you control. Works with n8n, Home Assistant, or any service that accepts a generic webhook.

Setup:

1. In Gitea Mirror, go to Configuration > Notifications
2. Enable notifications and select Webhook
3. Set the Webhook URL to your endpoint
4. Optionally set a Signing secret

Payload:

{
  "title": "Mirror Failed: my-repo",
  "message": "Repository my-repo failed to mirror",
  "type": "sync_error",
  "timestamp": "2026-08-03T02:33:29.707Z"
}

Signature verification: When a signing secret is set, every request includes an X-Webhook-Signature header containing sha256=<hex>, an HMAC-SHA256 digest of the raw request body. Verify it on the receiving end:

const crypto = require("node:crypto");
const expected = "sha256=" +
  crypto.createHmac("sha256", secret).update(rawBody).digest("hex");
const valid = crypto.timingSafeEqual(
  Buffer.from(signatureHeader), Buffer.from(expected));

The secret is encrypted at rest.

Event Types

Event	Default	Description
Sync errors	On	A mirror job failed
Sync success	Off	A mirror job completed successfully
New repositories discovered	Off	New repositories were discovered and imported; the three switches below select which ones
In your account	On	Repositories owned by your account
In an organization	On	Repositories of one of your organizations
Starred repositories	On	Repositories you starred, all stars in one alert

The three group switches are sub-options of "New repositories discovered": they only apply while that switch is on, and a configuration saved before they existed counts as all three on (they are keys inside the stored settings JSON, so no database migration is involved). Each enabled group is sent once per group per discovery pass (scheduled sync, boot auto-start and the manual "Mirror Organization" sync), listing the repositories that were imported: one alert per account, one per organization, and a single "Starred" alert for every star because their owners are arbitrary. A large import is capped to the first 10 names plus an "and N more" line so one pass never floods your provider.

Testing

Use the Send Test Notification button on the Notifications settings page to verify your configuration. The test sends a sample success notification to your configured provider.

Troubleshooting

Notifications not arriving:

• Check that notifications are enabled in the settings
• Verify the provider configuration (URL, topic/token)
• Use the Test button to check connectivity
• Check the server logs for [NotificationService] messages

Ntfy authentication errors:

• Ensure your access token is correct
• If self-hosting, verify the ntfy server allows the topic

Apprise connection refused:

• Verify the Apprise API server is running and accessible from the Gitea Mirror container
• If using Docker, ensure both containers are on the same network
• Check the Apprise server logs for errors

Tokens and security:

• Notification tokens (ntfy access tokens, Apprise tokens) are encrypted at rest using the same AES-256-GCM encryption as GitHub/Gitea tokens
• Tokens are decrypted only when sending notifications or displaying in the settings UI
