Xsolla Documentation

Overview

Webhooks allow you to receive notifications of events that happen to your Xsolla transactions. Use webhooks to automate back-end and supplementary functions, such as providing status and other transaction-related information.

We use webhooks for payments, including purchases of virtual currency, items, games, physical goods and so on.

In most cases, webhooks are triggered by user actions on your website. But they can come from other actions, too. For example, a back-end process on your website may invoke an API method to refund a payment, or the payment system may send a notification about a disputed charge.

You must write or use a so-called listener, or handler, to receive and process webhooks. This is a program that waits for a webhook and usually passes it to an internal workflow of yours, which responds appropriately.

For example, you can do the following after receiving a webhook:

Filling up a user’s balance
Unlocking new item for a user
Delivering physical goods to a user

Listen to webhooks at the following IP addresses: 185.30.20.0/24, 185.30.21.0/24, 185.30.23.0/24.

Notice: Your database must NOT contain two successful transactions with the same ID. If your listener receives a webhook with an existing transaction ID, it must return the latest result for that transaction. Avoid charging the user twice or creating duplicate records in your database.

We cannot guarantee that your listener will receive all the webhooks we send. As internet connection is not 100% reliable, webhooks may fail to come on time or at all. Moreover, your listener may return a 5xx HTTP code for a temporary error on your server. For example, your listener returns a 500 HTTP response code in case a virtual item that a user purchased successfully was not added to the user's inventory.

To reduce the risk of lost messages, the Xsolla alert service uses a retry mechanism. For messages that don’t reach their destination, the service resends them per the following frequency:

2 times with an interval of 5 minutes
7 times with an interval of 15 minutes
10 times with an interval of 60 minutes

A repeated webhook may be sent within 12 hours after the previous one. The maximum number of retries is 20.

Note: Although connection problems may indeed result in lost, delayed, or duplicate webhooks, the most common cause is faulty logic on the listener side.

Response Codes

Xsolla API accepts conventional HTTP response codes for successful and failed requests. Code 204 indicates successful processing. Return code 400 in case of an error in the provided information (e.g., a required parameter missing, a failed recharge, etc.). Use code 500 for temporary errors with your servers.

Sign Requests

Digital signatures enable secure data transmission. To generate the signature, (1) concatenate the request's JSON body with your project's secret key and (2) apply SHA-1 hashing to the resulting string.

Make sure that the created signature matches the one passed in the HTTP header.
