Forgejo supports webhooks for repository events. This can be configured in the settings page /:username/:reponame/settings/hooks by a repository admin. Webhooks can also be configured on a per-organization and whole system basis. All event pushes are POST requests. The methods currently supported are:

• Forgejo (can also be a GET request)
• Gitea (can also be a GET request)
• Gogs
• Slack
• Discord
• Dingtalk
• Telegram
• Microsoft Teams
• Feishu
• Wechatwork
• Packagist

Event information

The following is an example of event information that will be sent by Forgejo to a Payload URL:

Example

This is an example of how to use webhooks to run a php script upon push requests to the repository. In your repository Settings, under Webhooks, Setup a Forgejo webhook as follows:

• Target URL: http://mydomain.com/webhook.php
• HTTP Method: POST
• POST Content Type: application/json
• Secret: 123
• Trigger On: Push Events
• Active: Checked

Now on your server create the php file webhook.php

<?php

$secret_key = '123';

// check for POST request
if ($_SERVER['REQUEST_METHOD'] != 'POST') {
    error_log('FAILED - not POST - '. $_SERVER['REQUEST_METHOD']);
    exit();
}

// get content type
$content_type = isset($_SERVER['CONTENT_TYPE']) ? strtolower(trim($_SERVER['CONTENT_TYPE'])) : '';

if ($content_type != 'application/json') {
    error_log('FAILED - not application/json - '. $content_type);
    exit();
}

// get payload
$payload = trim(file_get_contents("php://input"));

if (empty($payload)) {
    error_log('FAILED - no payload');
    exit();
}

// get header signature
$header_signature = isset($_SERVER['HTTP_X_FORGEJO_SIGNATURE']) ? $_SERVER['HTTP_X_FORGEJO_SIGNATURE'] : '';

if (empty($header_signature)) {
    error_log('FAILED - header signature missing');
    exit();
}

// calculate payload signature
$payload_signature = hash_hmac('sha256', $payload, $secret_key, false);

// check payload signature against header signature
if ($header_signature !== $payload_signature) {
    error_log('FAILED - payload signature');
    exit();
}

// convert json to array
$decoded = json_decode($payload, true);

// check for json decode errors
if (json_last_error() !== JSON_ERROR_NONE) {
    error_log('FAILED - json decode - '. json_last_error());
    exit();
}

// success, do something

There is a Test Delivery button in the webhook settings that allows to test the configuration as well as a list of the most Recent Deliveries.

Authorization header

Forgejo webhooks can be configured to send an authorization header to the target.

The authentication string is stored encrypted in the database.
