Webhooks

Introduction

Webhooks allow you to listen to certain events on Toornament. When one of those events happen, an HTTP POST request is sent to your configured webhook URL.

Concept

A webhook is linked to an application. You can find the list of your webhooks on the Applications page.

Example of a webhook

{
    "name": "My webhook",
    "url": "http://toornament.com/webhook",
    "enabled": true
}

Example of a subscription

{
    "event_name": "registration.info_updated",
    "scope": "tournament",
    "scope_id": "842693950880972836"
}

First you need to define a webhook (see webhook endpoint). Each webhook subscription (see subscription endpoint) has specific scope and scope_id parameters used to limit the entity events the webhook listens to.

Scopes

The Webhook API currently support the following webhook scope:

tournament
Listens to a specific tournament. The scope_id is the tournament_id.
project
Listens to a specific project. The scope_id is the ID of the project.

}

Available Object Types

Security

Webhook URL legitimation

To ensure your webhook URL is a legit URL, a HTTP HEAD request will be sent with the X-Webhook-Secret header. To validate your webhook, the response to this request must return a 200 HTTP Response with the same X-Webhook-Secret header. Save the X-Webhook-Secret header as you will need it for payload validation.

Payload Validation

In each HTTP POST webhook, a X-Webhook-Signature header is added to the request to ensure that payload has not been altered. To validate the body content you need to concatenate the body response with the X-Webhook-Secret header and hash the result with sha256. The result string must be the same as the X-Webhook-Signature.

Retry policy

If the Toornament servers can not contact the webhook URL, the servers will try to send the data again during the next 24 hours.

So we can not ensure the event payloads will be delivered in the correct order. To prevent any error, we recommend you retrieve the entity concerned by the event to make sure you have its latest state.
