Webhooks

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 (default webhooks on repository creation or instance-wide webhooks). The currently supported webhook types are:

Raw event as JSON or FORM payload:

  • Forgejo (GET or POST)
  • Gitea (GET or POST)
  • Gogs (POST)

Dedicated integration:

  • Packagist: ask packagist to refresh the given package
  • SourceHut Builds: submit build manifests (only on push)

Generic notification messages in chosen channel/chat:

  • Matrix
  • Slack
  • Discord
  • Dingtalk
  • Telegram
  • Microsoft Teams
  • Feishu / Lark Suite
  • WeCom (Wechat Work)

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://example.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.
